WAPIR Issue 1.0 2
Product Overview
The 3-wire wall or ceiling mounted passive infra-red occupancy switch (WAPIR) should be wall
mounted at a locaon where a neutral connecon is available. The WAPIR incorporates a passive
infra-red quad sensor to detect movement of a warm body within the detecon zone (diagram B
or C) and a photocell to monitor the ambient light level.
Upon detecng movement, if the ambient light is dark enough, the
WAPIR switch will turn the load on. The ambient threshold can be set
by the user to between approx. 30 lux and 1000 lux and maximum
(photocell inacve) at the PIR via the LUX adjuster (diagram A). If no
more movement is detected within a pre-selected me, then the
WAPIR switch will turn the load o. This me lag can be set via the
TIME adjuster to 10, 20, 40 seconds, 1 min 15 secs, 2 min 30 sec, 5m,
10m, 20m or 40 mins ( diagram A).
The WAPIR also incorporates a sensivity adjuster. Turn fully clockwise
for maximum range and sensivity of the occupancy detecon.
Several WAPIR units can be wired in parallel, using re-wired 2-way lighng wiring to allow
mulple PIR detectors (diagram E).
Loading Limits:
The WAPIR should only be connected to a 230V 50Hz AC supply.
The PIR switches can switch up to:
•6 amps (1500W) of electronics or wire wound transformers
•6 amps (1500W) of compact uorescent loads
•3 amps (750W) of electronic and wire wound transformer loads
•2 amps (500W) of CFL. 2D Lamps, LED Drivers and LED lamps and ngs
•1 amp (250W) of fans
Minimum Load
Minimum load 2W resisve, suitable for most energy saving lamps, LEDs and emergency ngs.

Installaon Procedure
1. The switch should be placed facing the area where acvity is expected, if wall mounted at
between 1 and 1.8 mm high (diagram C). If the photocell override facility is required, the
switch must be sited in a posion where daylight can give greater illuminaon than the
arcial light
2. Connect the WAPIR as:
a. L – Live in
b. N – Neutral in
c. SL – Switched line out.
3. A few WAPIR’s products can be wired in parallel to control the same load (see diagram E).
4. There are three adjustments on the underside of the switch: TIME, LUX and SENS
(sensivity) (Diagram A).
5. When the wiring has been completed and veried, switch on the supply and test operaon.
When the PIR is powered up, it will switch on the load for 1 minute, the load will then switch o
and the PIR will enter its Operang Mode. If a manual override-o switch is posioned before
the PIR in the circuit (Diagrams D&E, note 1).
It will do this each me the wall switch is switched on. Alternavely, if the wall switch is placed
aer the PIR (Diagrams D&E, note 2) it will not enter the start-up mode each me.
LUX and Time Set-up
For convenience, ensure that the TIME is set to the minimum and the WAPIR is set to automac
mode when seng up the LUX level.
Aerwards se the TIME and SENS to values suitable for the applicaon. The LUX is best set up
when the local ambient light is close to the minimum desired light level. With the LUX set fully
clockwise, wait for the WAPIR to switch OFF. Rotate the LUX adjuster slowly anclockwise (- to +)
whilst waving your hand approximately 1m in front of the WAPIR, unl the load switches ON.
Adjustment – Typical Sengs
For indicaon see typical seng:
TIME: 10-20mins
LUX: Set fully clockwise (See above) SENS: 100%
All electrical installaon and maintenance must be carried out by a competent person. If in doubt,
consult a qualied electrician. Any new wiring must be carried out by qualied personnel in
accordance with the current edion of the IET Wiring Regulaons (BS7671).
Ensure the electrical supply is isolated before making any connecons or adjustments.

Fault Finding:
The load will not switch on:
❖The LUX adjuster is set too low and is inhibing the switch.
❖The moving body is not eming more than the background (person wearing insulang
clothing in a warm environment).
❖Person is too far from the PIR switch (see detecon diagram)
❖Person is moving unusually slowly (perhaps when tesng)
The load switches on when nobody is present:
❖Heater causing infra-red variaons in a small cold room.
oReduce the sensivity adjuster or re-site the WAPIR.
