Alarm Horn: Description and Operation
Description
DESCRIPTION
An alarm siren module 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 (3) extends from the housing and
connects the unit to the vehicle electrical system through a dedicated take out and connector of the engine compartment wire harness. The housing also
has a threaded insert within a mounting hole through which a screw (2) secures it to one of two mounting brackets.
A bell-shaped stamped metal mounting bracket (1) is used on vehicles with a diesel engine, while an L-shaped stamped metal mounting bracket is used
on vehicles with a gasoline engine. The diesel engine siren and bracket unit is secured by two screws and two spring nuts to the inboard side of the front
fender load path beam on the left side of the engine compartment, while the gasoline engine bracket is secured by a single screw and U-nut to an integral
stanchion of the molded plastic component tray on the right side of the engine compartment.
The alarm siren module cannot be repaired or adjusted and, if ineffective or damaged, it must be replaced.
