Safety and General Information

2.1

Company Liability The information in this manual has been carefully compiled and checked for technical accuracy. Multitone Electronics plc accepts no liability for inaccuracies or errors. In line with the company policy of technical advancement, the information within this document may be changed. The user should ensure that the correct issue of the document is used. Comments or correspondence regarding this manual should be addressed to: Multitone Electronics plc Technical Publications Hansa Road Hardwick Industrial Estate Kings Lynn Norfolk PE30 4HX England

2.2

Safety Summary The following information applies to both operating and servicing personnel. General Warnings and Cautions will be found throughout the manual where they apply. WARNING statements identify conditions or practices that could result in personal injury or loss of life. CAUTION statements identify conditions or practices that could result in equipment damage.

2.3

Operating Temperature Range The ambient operating temperature range is –30°C to +60°C (–22°F to +140°F) for the 25W transmitters and –30°C to +50°C (–22°F to +122°F) for the 40W and 50W variants. Ambient temperature is defined as the temperature of the air at the intake to the cooling fans.

2.4

Humidity The humidity should not exceed 95% relative humidity through the specified operating temperature range.

2.5

Dust and Dirt For uncontrolled environments, the level of airborne particulates must not exceed 100µg/m3.

2.6

Grounding and Lightning Protection

2.6.1

Electrical Ground A threaded grounding connector is provided on the rear of the tray, for connection to the site ground, or rack grounding point (for further details, refer to Section 4.2).

2

2.6.2

Lightning Ground It is extremely important for the security of the site and its equipment, that you take adequate precautions against lightning strike. Because it is outside the scope of this manual to provide comprehensive information on this subject, we recommend that you refer to your country’s standards organization, or regulatory body instructions for further instruction.

2.7

Ventilation Always ensure there is adequate ventilation around the transmitter. Do not operate at high duty cycles in a sealed cabinet. You must keep the ambient temperature within the specified range and we strongly recommend you ensure that the cooling airflow is not restricted. Important: - The cooling fans are mounted behind the front panel. To ensure adequate airflow through the transmitter, do not operate it for more than a few minutes with the fans disconnected (e.g. for servicing purposes).

2.7.1

Cabinet and Rack Ventilation Adequate cooling airflow is critical to the performance of the transmitter. The cooling airflow enters through the front panel and exits at the rear of the tray. For optimum thermal performance, the heated air that has passed through the transmitter must not be allowed to re-enter the air intakes on the front panel. Do not operate the transmitter at high duty cycles in a sealed cabinet. Each transmitter requires an unobstructed airflow of 18m3/h (11cfm). To allow enough cooling airflow through a cabinet mounted transmitter, we recommend the following: ■ a distance of 5cm minimum clearance to any obstruction to the front of the tray; ■ an open area of at least 50cm2 (8sq.in.) per tray of ventilation slots or louvres in front of the air intakes for the fans for each tray; for example ten 6×85mm (0.25×3.3in.) slots will allow the recommended airflow; ■ a distance of 10cm minimum clearance to any obstruction to the rear of the tray; ■ an open area of at least 50cm2 (8sq.in.) per tray of ventilation slots or louvres in the top of the cabinet, or to the rear of each tray; ■ a 2U gap at the top of the cabinet. Note The ventilation opening must be unrestricted. If the slots or holes are covered with a filter, mesh or grille, the open area must be increased to allow the same airflow as an unrestricted opening. The maximum ambient temperature entering the cabinet must not exceed the maximum temperature specified for the transmitter. If the transmitter is installed in a rack or cabinet with other equipment having different ventilation requirements, we recommend that it be positioned below this equipment.

2.7.2

Auxiliary Extractor Fans If multiple transmitters are fitted in a cabinet, auxiliary extractor fans may be required to ensure adequate cooling. If fitted, they should be capable of extracting 18m3/h (11cfm) per transmitter in the cabinet.

Compliance Information

3.1

EU Territories - This product complies with the requirements of the EU Radio & Telecommunications Terminal Equipment Directive 99/5/EC. A complete copy of the associated Declaration of Conformity for this and other Multitone products, may be found at the Multitone Internet address www.multitone.com. This is a Class 2 type equipment, under the terms of the R & TTE Directive and is therefore subject to restrictions in its use. Before installation and use, consult your local radio communications spectrum authority, for licensing and frequency regulations.

3.2

Installation Notes WARNING Do not install / use this equipment near sources of water, moisture, or in areas where explosive gases may be present! Do not expose to strong magnetic fields, extreme temperatures or strong sunlight. The equipment should be positioned so that there is no interference to the flow of air around the unit and away from sources of heat. It should only be mounted as recommended in the installation instructions. All installation wiring should be carried out in accordance with recognised Codes Of Wiring Practice, applicable to the equipment and circuits involved, e.g. Mains power, telephone and/or radio. Power supply cords and other leads should be routed so that they are not likely to be walked on, or pinched by items placed upon or against them. Particular attention should be paid to cord entrance and exit points. Where installation involves an external radio aerial/antenna, the antenna should be located away from power lines. Ensure that where applicable the antenna system is grounded, to provide some protection against voltage surges and the build-up of static charges. This equipment has been designed to conform to the relevant Radio and EMC performance standards, but it may be necessary to take additional precautions during installation, to ensure continued compliance. Use only cables supplied, or suitably rated power cables and screened signaling cable. Where quoted, do not exceed specified cable lengths and keep cable runs to a minimum, especially on the outside of buildings. Do not unnecessarily route wiring alongside cables from, or through, areas that are a source of interference e.g. heavy plant and switch rooms, RF transmitter housings, without taking suitable precautions to reduce EM interference coupling. Where necessary, use additional protection e.g. armoured trunking, surge arrestors, especially on the outside of buildings. Where any interference problems are observed, it may be required to fit additional filtering components such as ferrite absorbers, or in-line filters. If such action proves to be necessary, contact either Multitone or their authorised agents.

3.3

Connection of Power Supplies Use only power sources specified, or supplied by Multitone. The use of another device will invalidate any declared conformity for this equipment, if as a result it ceases to conform to those standards on which conformity is based. The equipment should only be connected to a power supply as described in the operating instructions, as marked on the equipment, or supplied by Multitone. Do not overload outlets and extension cords, as this can result in fire, or electrical shock. Where the equipment power supply unit (where provided) has been supplied with a threewire grounding type plug, this plug will only fit a grounding type power outlet. This is a safety feature and should not be defeated. If you are unable to use a grounding outlet, contact your electrician. Where equipment has been has been provided with a polarised line plug (one blade wider than the other - US/Canada), this plug will only fit a power outlet one way. This is a safety feature and should not be defeated. If you are unable to insert the plug fully, try reversing the plug. If the plug still does not fit, contact your electrician to replace the obsolete outlet.

3.4

Servicing This equipment contains no user-serviceable parts. All repairs to be undertaken by qualified service personnel. In the case of a problem, please contact your service representative/agent. All the safety and operating instructions should be read before the equipment is connected and operated and retained for future reference. All warnings marked on the equipment should be strictly adhered to. No attempt should be made to remove any designated safety covers, as these areas contain voltages of a sufficient magnitude to constitute a risk of electric shock to personnel.

3.5

Disposal

WEEE DIRECTIVE & PRODUCT DISPOSAL At the end of its serviceable life, this product should not be treated as household or general waste. It should be handed over to the applicable collection point for the recycling of electrical and electronic equipment, or returned to Multitone or their agent, for disposal.

4.

Installation & Fitting The installation and servicing of this product must only be carried out by suitably qualified personnel.

4.1

Fitting For greatest security, the RPT702/703 should be mounted in a 19 inch equipment cabinet or rack (Fig.1), using M6 (or 0.25in) fixing screws, passed through each of the four mounting holes (1). Ensure that the unit is physically stable once all the leads have been connected and that there is adequate ventilation around the equipment. Route any cabling away from the unit and along the sides of the cabinet/rack, to avoid any obstruction to the airflow. If the equipment is to be transported after fitment, or subject to other vibration, then a suitable transit bracket is available (Fig.2 - 380mm depth rack/cabinet only), please ask Multitone for details.

Fig. 1 - RPT702/703 Transmitter mounting points, DC power and earth connections An earth wire MUST be fitted to the earth screw terminal (3) on the back of the transmitter, using the earth lead supplied, or suitable equivalent.

6

Fig. 2 Optional Rear Support Brackets (Transit)

Fig. 3 Optional Wall Mounting Configurations An optional wall-mounting bracket kit (1) is also available. Please contact Multitone for further details. The Multitone paging transmitter can be wall-mounted (Fig.3), by rotating the front mounting brackets and fitting the brackets supplied in the wall mounting kit to the rear of the chassis.

7

When the transmitter is wall mounted, ensure the airflow is from bottom to top (option 2, front panel facing down), or side to side (option 3). The transmitter will perform best in these orientations. We do not recommend mounting the transmitter with the airflow from top to bottom (front panel facing up), as testing has shown that recirculation of air may lead to overheating. When mounting the transmitter, ensure that the areas in front of the air intake and air exhaust are free of obstructions, to allow unrestricted airflow. 4.2

Power Supply The DC power supply connection to the equipment is via the terminal connector (4) on the rear of the unit. The required I/P is nominally 13.8V DC (10 – 16VDC) at a current level up to 13A (dependent upon RF power option). You must connect the DC supply from the battery to the transmitter via a readily accessible disconnect device such as a fuse or DCrated circuit breaker with the appropriate rating, 15A. Where ac mains operation is required, a suitable external power supply is available from Multitone. For safe connection to the DC I/P terminals (M4 screw) the use of 8AWG/8.35mm2 cable is recommended for cable lengths 1.5 – 2m, with suitable crimp ring-connectors fitted to the cable ends. The overall voltage drop over the length of the cable should be less than 0.2V, so if the length of the power cable exceeds 2m, then the gauge of wire used should be reviewed, to minimise loss. NB When connecting the RPT702/703 equipment to an RPE1600/1650 Firecoder, ensure that the power connector is located in the 12V 8A socket only and that the Firecoder is not powered-on at the time of connection, as damage to the Firecoder may occur! Where the RPE1600/1650 has a number of auxiliary items connected to the 12V dc sockets, it is advised that a separate 24/12V dc-dc converter is used to power the transmitter, otherwise overloading of the Firecoder equipment may occur, resulting in a critical system failure.

4.3

Aerial and RF Output Always ensure that the transmitter is operated with a suitable load connected to the RF output, to prevent damage to the output power stage. The impedance of the aerial/load should be 50 Ohms and it is recommended that this be connected to the transmitter by a suitably rated 50 Ohm coaxial cable, of minimum grade type UR67, or RG213U, terminated with an “N” style RF connector. Where cabinet space is restricted, it is recommended to use an elbow style adaptor, to enable easier exit of the aerial cable. Should a poor load or connection be detected, the transmitter will automatically revert to a low RF power output level of approximately 12W. For added protection, a temperature sensor also ensures that the transmitter power is reduced to very low levels should a temperature threshold be exceeded. If the temperature does not decrease, the transmitter is switched off.

Do not operate the transmitter unless you have checked that all RF connections are secure, or if someone is located within 3m of the antenna!

Alternatively, where a Serial port is not available on the PC, a USB-RS232 adaptor may be used. After connecting the programming lead, install the software provided to a folder on the hard drive of the PC. Check that all connections are secure and that the TX/RX switch on the front panel is set to the TX mode. Connect power to the transmitter and switch on; the LCD should display the current channel number and the “On” LED will show green. Activate the programming software program on the PC. The programming application allows the transmitter configuration parameters to be read, edited and written back to the equipment. It has been optimised for mouse navigation and features are easily enabled and configured using a check box or drop-down list. The frequencies for each required channel are simply typed into a table. The application will open with a “general” front window, as shown below:-

It may be necessary to set the communication path to the PC, by selecting the COM port. This is done by selecting the Tools option from the top level menu and then Options. This will open the Options window as follows:-

30

Select the Communication Port drop-down window and select relevant COM Port. Leave the Default Access Level set to High, but other features may be selected according to preference. Once options have been selected, press OK. Next, select the TB7100 Tx mode:-

31

From the main Toolbar, select the “Read the Radio” option:-

The program will open a sub-window and read the current settings for the equipment:-

Once this has been completed, the program will revert to the main window. From the Options List at the side of the main window, select the “Channel Select” option.

32

The “Summary” window will open, showing the currently programmed parameters. From here it is possible to edit the parameters as required, either in this window, or by further selecting the “Detailed” option.

33

From the “Summary” window, each parameter may be selected by clicking onto the white parameter value area. In the case of the Tx frequency, it is necessary to double-click this area to gain access to edit the values.

For the other options a drop-menu will appear, giving a number of values. The required value may be selected by clicking on the numbers displayed. The chosen value will automatically be entered into the parameter area.

34

Selecting the “Detailed” option opens a new window, in which all the parameters are displayed and may be edited in a similar manner to the “Summary” window.

Should it be required to add new channels to the equipment, this may be done by selecting the “Add” button and entering the desired values in the relevant boxes. Once the parameters have been loaded, the “Program the Radio” option from the main Toolbar:-

Initially the program will open an “Interrogate” window and once the existing details have been confirmed, this will switch to the “Programming” window, with the progress bar.

35

If additional confirmation of programming is required, the equipment may be reinterrogated using the “Read Radio” function from the main Toolbar. If it is required to program the further options as listed in Sections 9.2 – 9.5, then these may be accessed from the main programming window and adjusted according to the restrictions given in the related tables.

Re-setting the RF Power Level

During installation, it may be necessary to increase or decrease the RF output power level setting for the transmitter, in order to meet local licensing regulations, or match to the aerial network. This can be achieved by the use of the Programming Kit 2326-0026. This adjustment should only be carried out by qualified personnel. Before attempting to make any adjustments, ensure that the transmitter RF output is connected either to an RF power meter and 50 Ohm load, or via a thro’-line power meter, to the aerial system. Connect the test lead and ensure that the transmitter is set as per section 10, paragraphs 1-3 and activate the “Calibration Application” program on the PC.

From the opening page toolbar, select the Tools option, followed by COM Port. Select the Communication Port drop-down window and select relevant COM Port to communicate with the PC. Leave the Default Access Level set to High, but other features may be selected according to preference. Once options have been selected, press OK.

37

From the Toolbar, select Read the Radio (yellow icon) and download current parameters. From the left-hand menu options, select Tx Power Control. The window should now display the current settings for the transmitter.

From the given options in the window, select the Test Frequency closest to the actual frequency of the transmitter under test. Select the Next button and step through the menu Instructions to Step 3.

38

Identify the required Target Power Level range which corresponds to the power level which requires modification. Adjustment may be effected from either the UP/Down button icon found on either side of the slider, or the slider itself. The slider option provides quick and quantum adjustment, whilst the button will allow for more accurate single digit changes in the level value. If the button has been chosen, left-click on it with the mouse and the transmitter will key-up. Note the measured RF power on the power meter. Continual clicks of the mouse will increase or decrease the transmitter output power, according to which button has been selected. The change in value will be shown in the window to the RHS of the slider and this can be noted against the original Current Value, read from the transmitter earlier. To use the slider, place the mouse cursor onto the slider and a window showing the current value will appear. Left-click the mouse button onto the slider cursor and hold the button down. The transmitter will key and the cursor may then be slid up or down to vary the power level; the change in value will be noted in the small window which tracks the cursor. Once the desired power level has been reached, release the mouse button. Select the green tick Accept Changes icon. Once this icon has been pressed, the transmitter will power-down.

39

Where the desired operating frequency falls midway between two of the Test Frequencies, in order to maintain consistent operation, it may be necessary to repeat the previous adjustment steps on the Test Frequencies either side of the operational frequency. Where an equipment is programmed for multi-channel use, then it will be necessary to make adjustment across all of the Test Frequencies. Once all adjustments have been made, select and press the Program Radio icon.

When given the overwrite option in the exit window, select Yes.

Program will exit and close. Key the transmitter from the associated control system, or link pins 1 & 4 on the 9-way FSK connector (see Section 6.3), to check that the reset power level is functioning correctly.

12. Re-setting the Modulation Level This adjustment should only be carried out by qualified personnel. Before attempting to make any adjustments, ensure that the transmitter RF output is connected to an RF power meter and 50 Ohm load, with a suitable attenuation device providing connection to a modulation monitoring instrument. The modulation level is normally factory set, according to the customer sales requirements and should not normally need adjustment. However should this not be the case, it is possible to adjust the set modulation level in the field, providing that the correct instrumentation is available:i. A function/arbitary waveform generator; ii. RF power meter with load; iii RF attenuator; iv. Modulation meter v. Test lead (see text for details). Remove the top equipment cover, to expose the Paging Interface PCB.

Connect the test lead/connector 9way D (female) to the FSK Encoder 9-way D (male) socket on the rear of the transmitter. This lead/connector should be wired to provide a data input on pins 3 & 4 and a Tx key function on pins 1 & 4. In both cases, pin 4 is ground. Connect and set the waveform generator to provide a 256Hz, 5V p-p square wave O/P between pins 3 & 4 of the test lead. Key the transmitter by connecting Pins 1& 4 of the connector. Adjust RV2 on the Interface PCB to give the desired modulation deviation (4.5kHz max. for a 25kHz channel spacing system). Replace the unit cover and check the modulation level with the customer’s system, to ensure that system over-deviation is not occurring.
