Coverage Information
The recommended mounting height range is 2.4 m (8 ft) to
5.5 m (18 ft). The pattern consists of 64 zones grouped into
16 barriers, with one additional zone looking straight down
from the unit (sabotage). Each barrier is 9.2 m (30 ft) long
and 1.3 m (4.4 ft) wide at 9.2 m (30 ft).
There is a choice of two optical modules depending on
ceiling height. These choices provide 360° by 18.3 m (60 ft)
diameter coverage when mounted on 2.4 m (8 ft) to 5.5 m
(18 ft) high ceilings.
Wiring Considerations
Do not use shielded cable. Use wire that is no smaller than
0.8 mm (22 AWG) to connect the detector to the control
panel.
Technical Specifications
Environmental Considerations
Temperature
(Operating):
-29°C to +49°C (-20°F to +120°F). For UL Listed Re-
quirements, the temperature range is 0°C to +49°C
(+32°F to +120°F).
Power Requirements
Standby Power: There is no internal standby battery. Connect to
DC power sources capable of supplying standby
power if primary power fails. For each hour of
standby time needed, 350 µAh are required.
For UL Listed Requirements, four hours (1400
µAh) minimum is required.
Voltage (Input): 12 VDC from panel's MUX bus and optionally
from an auxiliary power supply.
Current Draw (two-wire):
LED Off: < 350 µA draw on MUX bus
In Alarm; LED On: 2 mA draw on MUX bus
Current Draw (four-wire):
LED Off: < 350 µA draw on MUX bus, 0 mA draw on Aux.
power
In Alarm; LED On: < 350 µA draw on MUX bus, 3 mA draw on Aux.
