Alarm Horn: Description and Operation

SIREN (EXPORT)

Fig.6 Vehicle Theft Security Siren:

Some vehicles equipped with the premium Vehicle Theft Security System (VTSS) utilize a separate siren. This siren is dedicated to the Vehicle Theft Security System (VTSS) and is controlled by the ARKEM module (Remote Keyless Entry). The siren can reach sound decibels as high as 110 dB. A internal battery-backup power source and auto detect feature are also built into the siren. The internal battery-backup provides sufficient power to sound the alarm even if the vehicle's electrical system is depleted. The auto detect feature has the ability to sound the siren if any of the wires (voltage supply, ground and signal) leading to the siren are cut while the system is armed.

In the event the vehicle theft security is triggered, the ARKEM module will sound the siren.
