TAMPER
The sensor is protected against tampering attempts by two controls: cover anti-opening and anti-removal (this one uses both
inclinometer and electro-mechanic technologies).
When the sensor is in TEST mode, a tamper event is signalled by 5 slow “beeps” sequence and blue alarm LED (buzzer must be
enabled, set DIP6 = ON).
ANTI-OPENING
Protection against the cover opening.
To enable/disable this function act on
J4
jumper:
J4
= closed
Tamper disabled
J4
= opened
Tamper enabled
ANTI-REMOVAL
Double protection against sensor removal from installation place: electro-mechanic and inclinometer.
Electro-mechanic
Protection activated by opening of the tamper switch on the back of the case (normally closed because the sensor is fixed on
the wall).
To enable/disable this protection act on
J5
jumper:
J5
= closed
Back tamper disabled
J5
= opened
Back tamper enabled
Inclinometer
Electronic protection obtained by digital inclinometer on board.
As soon as the sensor is tilted of about 30° (any direction), the tamper alarm starts.
To enable/disable this protection act on jumper J6:
J6
= closed
Inclinometer tamper disabled
J6
= opened
Inclinometer tamper enabled
Disable this protection only if the detector is subject to vibrations, installed not in vertical position or during in stallation and
test.
