Coverage Information
The recommended mounting height is:
•
3.1 m (10 ft) for the A200 mirror
•
2.3 m (7.5 ft) for the A80 and A120 mirrors
Mounting Considerations
The detector may be surface or corner mounted, but use of
the B334 Mounting Bracket (included) is strongly
recommended. Because variations exist in the surfaces of
most mounting walls, most units are not mounted at perfect
angles to the floor or walls. This may cause the pattern to
point away from the "ideal” direction. To ensure proper
catch performance, mounting the detector on a bracket
permits the flexibility needed to adjust the direction of the
coverage pattern.
Misalignment of the detector when using an optional
mounting bracket might reduce the range and increase
dead zones.
Wiring
Do not use shielded cable. Use wire no smaller than 0.8 mm
(#22 AWG) to connect the detector to the control panel.
Technical Specifications
Environmental Considerations
Temperature (Oper-
ating):
-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
Current Draw (2-wire):
LED Off: < 350 µA draw on mux bus
In Alarm; LED On: 2 mA draw on mux bus
Current Draw (4-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. power
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 Re-
quirements, 1400 µAh (4 hrs.) minimum is required.
Voltage (Input): 12 VDC from panel's mux bus and optionally from an
auxiliary power supply.
