General
The RS motion detector system is an ideal outdoor security
system. It uses passive infra-red technology to detect heat
radiation within its sensing zone. At night, upon detection, the
system lights up the halogen lamp to illuminate the area. The
light-on period is fixed at three minutes. A built-in sensor turns
off the motion sensor during daylight hours to save energy and
lamp life.
Selecting a location
The higher the unit is mounted (up to a maximum of six metres
above ground level), the larger the detection area. Refer to the
zone coverage chart below (figure 2).
Note: Sensitivity of the unit can be affected by temperature and
climatic conditions. Reflective surfaces e.g. pools of
water and swaying trees in the detection area may
falsely trigger the unit.
Mounting
1. Remove the four top housing screws using a screwdriver.
2. Position the bottom housing at desired location and make
markings on the wall through the three screw holes.
3. Drill the three marked points to about 40mm depth and insert
the screw pegs. Before mounting the bottom housing onto
the wall, the mains supply cable and optional slave lamp
loads cable need to be inserted through the wire gasket.
4. Place the bottom housing over drilled holes and screw it tight
with the three long screws provided.

1. Feed the mains input cable through one of the wire gaskets
located at the back of the bottom housing, ensuring a water
tight seal is maintained.
2. The unit switches up to a maximum of 1200W halogen lamp
load, including the integral 300W lamp. Hence, the slaving
capability can be utilised through additional wiring up to
900W maximum.
3. Attach the wire into the connection box as shown in figure 4.
Operation
1. Test: When the power is initially switched 'on', the light will
operate for four seconds when movement is detected
regardless of the external lighting level.
2. Automatic: After five minutes in the test mode, the unit
switches into automatic mode. In this mode, the light will
activate after motion has been detected during the hours of
darkness only. The lamp will remain lit for three minutes.
3. Override: By connecting the unit to a wall switch in series
with the power supply, it is possible to manually override the
unit.
At night, turn the wall switch 'off' for more than 0.5 seconds,
but less than 2 seconds, then immediately turn it back 'on'.
The lamp will be activated to remain on until dawn. As the
built-in photocell detects daylight, the unit will turn the light
'off' and return the unit to automatic mode operation. To
return the unit to automatic mode, whilst it is operating in
override mode at night, turn the wall switch 'off' for more
than 10 seconds and then turn back 'on' again. The unit will
switch into test mode and, at the end of 5 minutes, the unit
switches into automatic mode again.
Lamp replacement
Allow lamp to cool before replacement.
1. Unscrew the glass cover.
2. Slide the lamp tube to the right-hand side to free the left-
hand side from the slot of the lamp fitting and remove it.
3. Use a clean dry cloth to handle the new lamp. Hold the
lamp with the cloth at one end, place the other end into the
left-hand spring-loaded socket and then push inward to
place the other end of the lamp into the right-hand socket.
4. Fasten the glass cover to the lamp housing.
