1. General Information
These instructions should be read carefully and retained for further reference
and maintenance.
2. Safety
• Before installation or maintenance, ensure the mains supply to the PIR
sensor is switched off and the circuit supply fuses are removed or the
circuit breaker turned off.
• It is recommended that a qualified electrician is consulted or used for the
installation of this PIR sensor and install in accordance with the current
IEE wiring and Building Regulations.
• Check that the total load on the circuit including when this PIR sensor
is fitted does not exceed the rating of the circuit cable, fuse or circuit breaker.

4. Selecting a Location
• Careful positioning of the sensor will be required to ensure optimum
performance. The mounting height for the sensor should be 2.5m.
See diagram A.
• The sensor is more sensitive to movement ACROSS its field of vision than
to movement directly TOWARDS. Therefore position the unit so that the
sensor looks ACROSS the likely approach path.
• Avoid positioning the sensor where there are any sources of heat in the
detection (extractor fans, tumble dryer exhausts etc.). See diagram B.
• Reflective surfaces (i.e. pools of water or white-painted walls)
may cause false activation under extreme conditions.

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).
5.2 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).
5.4 With both lugs pressed in, remove the font cover by pulling it away
from the PIR sensor (See image 3).
