Door Lock Actuators

The CTD system uses the door jamb switches in the door lock assembly as one method to activate the alarm. The Driver Door Module (DDM) monitors all door jamb switches via a discrete input or the Door Lock Serial Data (DLSD) from the other door modules. If the Remote Control Door Lock Receiver (RCDLR) receives a class 2 message from the DDM that a door is open and the CTD system is armed, the RCDLR activates the alarm.
