4. Installation

Refer to the illustrations on page 2 of this manual.

The installation must be carried out by a qualified person.

1. Choose a proper location for the sensor. Avoid places where

temperature changes frequently, e.g. near air conditioners or

heating devices. Also avoid moving obstructions or objects in the

detection field of the sensor to prevent unnecessary activation.

2. The PIR sensor must be installed inside a hole which is max.

14 mm in diameter. The controller can be installed on the other

side of the wall, inside a dropped ceiling or, behind a false wall.

Leave sufficient space (at least 2 cm) around the controller for

ventilation.

Notes:



The lead wires of the sensor are ± 20 cm long. When mounting

the controller on the other side of a wall, drill a hole of at least

14 mm for the connector and wires to go through.



Make sure the controller is accessible at all times when installing

inside a dropped ceiling or behind a false wall. However, it should

be sufficiently protected to avoid accidental touching!

3. Electrical wiring must be present at the installation location.

4. Deactivate and remove the fuse of the electric circuit on which

you want to install the device.

5. Connect the sensor to the controller [2]. The connector fits only

one way, do not force.
