1.0 INTRODUCTION
The Passive Infra Red (P.I.R) movement detector works by
detecting the warmth of moving bodies walking through the
area.
When the P.I.R is triggered it will signal the fan or light to run. The
“timer” will run on for the time set. The focusing of the unit is in
fact made up of a number of smaller lenses known as facets or
zones, each zone is focused on a dierent spot to give a wide
area of coverage.
The P.I.R. is triggered when walking from one zone to the next.
Therefore for optimum detection sensitivity it will operate best
when walking across the zone patterns.
Code Description

230 - PIR
1. Voltage: 230 = 230V Supply
2. Detector Type PIR = 10A (max load) passive infra-red
detector with adjustable timer.
1 230-PIR Sensor
When using for lighting and fan control, whilst this is suitable
for several fans, only one light fitting should be connected
directly to the P.I.R.
Please note there are high voltages which exist
inside the unit and under no circumstances
should it be opened, there are no user
serviceable parts inside.
IMPORTANT
2.0 INSTALLATION
The P.I.R. must be installed in accordance with the latest IEE
recommendations.
Before installing the unit or making any adjustments the
electricity must be switched o.
Max Ceiling Height: 4m
Detection Range: 7 metres (max)

Install height: 2-2.5 metres
Detection Range: 7 metres (max)

3 Typical wall-mounted application
2.1 Positioning the P.I.R. unit
•For best results never position over a heat source.
•Never position in a draught.
•Do not place in direct sunlight.
•Take account of exit/entry points.
•Always seal PIR cable entry.
•Fix securely to wall or ceiling.
•Avoid obstructions such as screen/ furniture.
•Be conservative on range and angle.
•Avoid walking towards the PIR for prime detection.
•Avoid long ranges for instant triggering.

230-PIRInstallation Manual
Before installing the switch, the best position must be sought
bearing in mind that the unit has a range of up to 6 metres and
will provide 100° coverage in all directions. It also should be
noted that the units are not suitable for use in shower cubicles,
and should always be used in an indoor environment.
To avoid unnecessary triggering the P.I.R should not be mounted
in a draught or directly over a heat source such as a radiator.
Overloading the unit will result in permanent damage,
therefore it should not be used on loads over those stated
on the P.I.R.
After installing the fan the P.I.R should be wired to the
switch/timer.

PLEASE NOTE 2.3 Adjusting the Sensitivity
Set the DIP switches to TEST MODE (Shown in Section 2.2) and
gently rotate the LUX potentiometer (Figure 5) anti-clockwise
towards the plus (+) to the desired ambient light level that is
required. If the LUX is set too low the switch will not activate.

4.1 Powering Up the Unit
When the installation is complete, switch on the mains and wait
for the P.I.R to settle down. This could take up to 60 minutes
depending on how the timer adjustment is set. To check that
the P.I.R will settle down and switch o the fan, the P.I.R can be
temporarily “blinded” with a piece of paper in front of the lens to
stop the circuit triggering each time.
