This unit has been designed for the professional installer who requires large load
switching capabilities. The unit can be used for switching lights, heaters, fans,
motors etc. The control unit can be triggered by the use of 1804 or 1811 External
Sensors which detect a persons moving body heat, or a push button can be used
to trigger the system

220/240V 50/60Hz operating voltage.
Switches 8KW of load.
Adjustable light(s) on time control. (3 sec - 7 mins)
Adjustable lux level control. (sets the level of darkness at which the unit starts
to work)
100mA @ 12Vdc available from the power supply to power the external sensor
and other low voltage devices.
IP40 enclosure protection.
The number of External Sensors and other low voltage devices that may be
connected to the controller is governed by the current available (100mA). Add up
the current rating of each device to be connected to make sure it does not exceed
100mA. If you do require more current, an additional 12V do power supply will be
needed. Each Voltek External Sensor consumes 12mA(max) @ 12V dc
.
The control unit may be located at any convenient wiring point, that is not
subject to excessive heat, vibration or moisture.
SITING THE UNIT

Installation Instructions
FEATURES
4. Run a cable from the load (lighting, heaters, etc.) and connect the cable as
shown in the table on the right.
5. Locate and install the PIR sensors following the instructions supplied with the
sensors. Return to these instructions when it is time to connect the wiring.
6. Connect the sensors as shown below using a suitable cable such as four core
alarm cable.
SETTING UP
1. Turn the TIME adjustment and the LUX level adjustment fully anti-clockwise
ready for a daytime walk-test.
2. Apply power.
3. Walk in front of the PIR sensors and ensure that the load (lights) switch on
when desired. The load will switch off 2 seconds after you have stopped moving.
Pan and tilt the sensors to obtain the desired coverage.
4. Remember that the detection range will increase slightly
at night time due to the lower ambient temperature.
5. If you only want the load to switch on at night-time when it is dark, such as in a
lighting system, turn the LUX adjustment to the half way position to set the
system for night-time only operation. Walk in front of a PIR sensor and check
that the load doesnt turn on
6. Turn the TIME adjustment to the half way position to allow the load to switch on
for 3 minutes after movement has stopped. This can be increased or decreased
to suit individual needs.
The Installation is now complete.
7. Note : only one of the External Sensors on the system should be connected
to the L terminal. This sensor will supply the control unit with information of
how light or dark it is.
8. Note : an over-ride or a timed lights button can also be installed as shown
above.
