Door Lock Actuators

The CTD system uses the door jamb switches that are internal to the door lock actuators as one method to activate the alarm. The door modules monitor the door jamb switch via a discrete input to the appropriate door module. When the door is open the door jamb switch grounds the door open input to the door module. The CTD system uses the driver door unlock switch that is internal to the driver door lock actuator to disarm an armed system. The Driver Door Module (DDM) monitors the driver door unlock switch via a discrete input. When the lock cylinder is turned to the unlock position the switch grounds the disarm input to the DDM.
