5. Installation
5.1 Ensure the mains supply is switched OFF
and the circuit supply fuses are removed
or the circuit breaker turned OFF (See image 1).
5.4 With both lugs pressed in, remove the font cover by pulling it away
from the PIR sensor (See image 3).
5.2 An isolating switch should be installed to enable the power to be switched
ON and OFF for maintenance purposes and to activate the manual/auto
override function.
5.3 Use a 2.5mm Allen key to unlock the captive latch located on the bottom
of the sensor, by turning it anti-clockwise (quarter turn) so the dot indicator
aligns with the ‘Unlock’ symbol, then pull downwards (See image 2, a).
Note: the captive latch cannot be removed.
Use a flat head screwdriver to press in the lugs on each side
of the PIR sensor to unfasten the front cover (See image 2, b).
