GF80.50-D-4005HA Acoustic Alarm, Function
- with CODE (FY1) ATA 2 with interior protection, towing sensor and battery-operated horn
When the anti-theft alarm system (ATA) triggers an alarm, the OCP control unit (N70) transmits the signal "ATA alarm" to the battery- operated horn (H3/1) via a bi-directional single-wire interface. The control electronics integrated into the battery-operated horn with data interface read in the signal and then actuate the battery-operated horn at intervals (2 Hz ± 0.2 Hz) of t = 25 s (parameterizable in increments of 5 steps from 0 to 60 s ).
Termination of alarm by ATA system
The alarm is interrupted when the "Unlock" transmitter button on the transmitter key (A8/1) is actuated, simultaneously the ATA system is deactivated. This is indicated by the turn signal lamps flashing once and the LED in the interior central locking button (N72/1s7) going out simultaneously.
The "Unlock" message from the EIS control unit (N73) is read in by the OCP control unit via the controller area network bus class B (interior compartment) (CAN B).
The "ATA_ST (ATA status)" is transmitted by the OCP control unit to the UCP control unit (N72/1) via the CAN-B.
