1. Battery life is calculated at an average of 20 activations per day
Installation
The detector is equipped with a tamper switch on the back cover. When
the detector is mounted correctly, the tamper switch will be
compressed. When the detector is removed from the back cover or the
wall, the tamper switch will activate and the detector will send a signal
to the receiver.

Choosing position for detector mounting
For best coverage, the detector should be mounted on a height of 2
meters above the ground.
Mounting
Wall mounting
1. Open the cover by removing the fixing screw at the bottom of the
detector.
2. Break through the desired knockouts on the back cover.
3. Use the knockout holes to screw the detector to the wall.
This method will enable the
tamper switch
function.
Corner mounting
With triangular bracket:
1. Break through the knockouts on the bracket.
2. Mount the bracket in the corner with the two pointing sticks on top
facing you.
3. Snap on the detector to the bracket
4. Screw the cover back on.
This method will enable the
tamper switch
function.
With knockouts in housing:
1. Open the cover by removing the fixing screw.
2. Break through the knockouts on the slanted sides of the housing.
3. Mount the detector in the corner.
4. Screw the cover back on.
The
tamper switch
will not be enabled with this mounting method.

No
ottee!! Do not mount the detector:
– Where the view is obstructed by e.g. curtains, ornaments etc.
– Directly facing a door contact (DCW), since the signals can interfere
– In direct sunlight
– Where the temperature can rapidly change, e.g. in an area with an air
condition unit
– Directly facing heat sources, e.g. boilers, open fires
– Above a radiator
– Where there are moving objects in the detection area, e.g. curtains
