Alarm Horn: Description and Operation
Vehicle Theft Security Siren - Description
DESCRIPTION
An alarm siren module (1) is part of the premium version of the Vehicle Theft Alarm (VTA) in the Vehicle Theft Security System (VTSS). The premium
version of the VTA is only available in vehicles built for certain markets, where the additional features offered by this system are required. This unit is
designed to provide the audible alert requirements for the premium VTA.
The alarm siren module consists of microprocessor-based electronic control circuitry, the siren, and a nickel metal hydride backup battery. All of the
alarm module components are protected and sealed within a molded plastic housing. An integral connector receptacle (2) extends rearward from the top
of the housing and connects the unit to the vehicle electrical system through a dedicated take out and connector of the headlamp and dash wire harness.
The housing also has a threaded insert within the mounting hole (3) on the back through which a screw secures it to a stamped metal mounting bracket.
The siren and bracket unit are located in a hollow behind the right end of the front frame crossmember outboard of the right front frame rail. A single
screw secures the mounting bracket to the right end of the front crossmember.
The alarm siren module cannot be repaired or adjusted and, if ineffective or damaged, it must be replaced.
