Unit I GENERAL INFORMATION DESCRIPTION The U1F-, U2F-UV/IR model controllers with UVC120 ultraviolet (UV) detector and IRC90H infrared (IR) detector provides fast reliable fire detection in environments where false actuation due to interference can be a problem. Such interference includes x-rays, gamma rays, electric arcs, and hot objects. These interfering agents can make either an infrared or an ultraviolet detection system alone unusable. By combining the two types of fire detection systems, reliable fire detection is possible in these environments without unacceptable false alarms. In order for an alarm condition to be actuated, both the UV and IR detectors must ‘see’ the fire. The UV and IR detectors monitor different portions of the radiation spectrum and fire is virtually the only source that will affect both types of detectors. This system makes it possible for arc welding and other projects to be performed on the premises without the need to shut down your fire detection system and leave your facility unmonitored. The controller comes with a full array of faceplate indicators, relay and current outputs, automatic and manual Visual Integrity (vi) testing.
