• Next to or directly above heaters or air conditioning vents, windows, wall vents etc. that can

change the direction of airflow and cause rapid temperature fluctuations.

• In very high or awkward areas (e.g. over stairwells) where it may be difficult to reach the unit (for

testing, hushing etc.).

• Locate away from very dusty or dirty areas as dust build-up in the optical sensor chamber can

impair performance. It can also block the insect screen mesh and prevent smoke from entering

the chamber.

• Locate the unit at least 1m from dimmer controlled lights and wiring as some dimmers can cause

interference.

• Locate the unit at least 1.5m and route wiring at least 1m away from fluorescent light fittings as

electrical “noise” and/or flickering may affect the unit. Do not wire into the same circuit as

fluorescent lights or dimmers.

• Do not locate in insect infested areas. Small insects getting into the optical sensor chamber can

cause intermittent alarms. Insects and contamination on the heat sensor can increase its

response time.

5. INSTALLATION

The Alarm is designed to be permanently mounted, using it’s own built-in terminal

block to connect it to the mains. The mounting plate can be screwed directly to the

ceiling. Alternatively it can be screwed to a standard junction box. It requires a current

of 60mA. The Alarm must not be exposed to dripping or splashing. There are important

markings on the underside of the alarm.
