Door Tamper Switch

The door tamper switches are connected to the front door lock cylinders. If a forced entry causes a front door lock cylinder to be moved in and out the attached door tamper switch to closes and the Remote Function Actuator (RFA) module detects a ground at terminal F10 (CKT 263, LT BLU). When the RFA module detects a ground condition at terminal F10 the Universal Theft Deterrent (UTD) system enters the alarm mode.
