DEACTIVATION
Deactivation may take place either in the surveillance state, or in the alarm state.
It is carried out by pressing the button on the transmitter, which instructs the BC to deactivate the alarm system in accordance with the following procedure: deactivation is indicated by two flashes of the blinkers at 1Hz ± 10%, d.c. 50% and two
beeps (the indication is enabled/disabled depending on the operating mode).
This indication is activated within 100 ms from receipt of the deactivation command:
- the siren is deactivated.
- the external modules are deactivated.
- the BC interrupts perimter protection and all counter-measures in progress, if there are any.
The command is also accepted in the presence of the +15 signal.
After carrying out deactivation and at the first Key-On, the control unit indicates discharged transmitter batteries, alarms from volumetric, anti-tilt, perimeter sensors,+15 and +30.
The indication takes place by the flashing of the dissuasion light for 120 ± 10% s.
The meanings of the flashing are as follows:
| Light on fixed: transmitter | batteries discharged (disguises all the indications) |
|---|---|
| 1 flash | one or more doors |
| 2 flashes | boot |
| 3 flashes | bonnet |
| 4 flashes | ultrasound module |
| 5 flashes | anti-tilt module |
| 6 flashes | +15 |
| 7 flashes | +30/earth |
| 8 flashes | serial line (no signal/incorrect signal from siren for more than 3 times) |
| 9 flashes | at least three causes of alarm |
The flashes last 0.5 s ON, 0.5 s OFF and the indications are repeated after a pause of 1.5 s. If there are two different causes of alarm, these are displayed in cycles.
