1. 2.

3.

Emergency Connection: Operate lamp(s) continuously upon loss of normal power. Connect unswitched circuit to battery-inverter unit and switched circuit to fixture ballast. Operation: Relay automatically turns lamp on when power-supply circuit voltage drops to 80 percent of nominal voltage or below. Lamp automatically disconnects from battery when voltage approaches deep-discharge level. When normal voltage is restored, relay disconnects lamps from battery, and battery is automatically recharged and floated on charger. Environmental Limitations: Rate equipment for continuous operation under the following conditions unless otherwise indicated: a.

b. c. d. 4.

Test Push-Button and Indicator Light: Visible and accessible without opening fixture or entering ceiling space. a. b.

G.

Ambient Temperature: Less than 0 deg F (minus 18 deg C) or exceeding 104 deg F (40 deg C), with an average value exceeding 95 deg F (35 deg C) over a 24-hour period. Ambient Storage Temperature: Not less than minus 4 deg F (minus 20 deg C) and not exceeding 140 deg F (60 deg C). Humidity: More than 95 percent (condensing). Altitude: Exceeding 3300 feet (1000 m).

Push Button: Push-to-test type, in unit housing, simulates loss of normal power and demonstrates unit operability. Indicator Light: LED indicates normal power on. Normal glow indicates trickle charge; bright glow indicates charging at end of discharge cycle.

Battery: Sealed, maintenance-free type. Charger: Fully automatic, solid-state, constant-current type with sealed power transfer relay. Integral Self-Test: Factory-installed electronic device automatically initiates coderequired test of unit emergency operation at required intervals. Test failure is annunciated by an integral audible alarm and a flashing red LED.

External Type: Self-contained, modular, battery-inverter unit, suitable for powering one or more lamps, remote mounted from luminaire. 1. 2.

Emergency Connection: Operate lamp(s) continuously. Connect unswitched circuit to battery-inverter unit and switched circuit to luminaire. Operation: Relay automatically turns lamp on when power-supply circuit voltage drops to 80 percent of nominal voltage or below. Lamp automatically disconnects from battery when voltage approaches deep-discharge level. When normal voltage is restored, relay disconnects lamps from battery, and battery is automatically recharged and floated on charger. Nightlight Connection: Operate lamp in a remote fixture continuously. Battery: Sealed, maintenance-free type. Charger: Fully automatic, solid-state, constant-current type. Housing: NEMA 250, Type 1 enclosure listed for installation inside, on top of, or remote from luminaire. Remote assembly shall be located no less than half the distance recommended by the manufacturer, whichever is less. Test Push Button: Push-to-test type, in unit housing, simulates loss of normal power and demonstrates unit operability.
