Principles of Operation
PRINCIPLES OF OPERATION - PERIMETER ALARMThe smart junction box (SJB) monitors the door ajar switches circuits 1312 (LG/BK), 1314 (YE/LG), 1432 (WH/VT), and 1433 (DB/LG), the anti-theft hood switch circuit 1304 (VT/OG), and the liftgate ajar switch circuit 1351 (TN). If any intrusion is detected without the alarm being shut off, the SJB energizes circuit 1324 (BK/LG) sounding the anti-theft horn, and circuits 1341 (DB/OG), 1342 (GY/BK), 1363 (WH/RD), and 1365 (GY/LB) causing the turn signal lamps to flash.
The system can be disarmed by opening the driver door with the key, grounding circuit 1313 (LB/BK) through the anti-theft inhibit switch; using the correct entry code on the remote keyless entry (RKE) keypad; unlocking the doors with the RKE transmitter; or turning the ignition switch to the ON position.
The system arms when the driver door is locked with the key; the doors are locked with the RKE transmitter; 7/8 and 9/10 on the RKE keypad are pushed simultaneously; or the doors are locked with the door lock control switch and then the doors are closed. The SJB queries the position of all entry points. If any entry point is open, the alarm arms excluding inputs from the open entry point. The SJB adds the entry point to the protected status when the closure of the open entry point is detected.
