The Park Brake Warning System is a unique product that incorporates the following features:
DOOR SENSING
The control unit senses when the door is opened or closed via proximity switches.
PARK BRAKE SENSING
The control unit senses the state of the park brake via a park brake switch.
OPERATOR WARNING
Operates a visual alarm and incorporates an output for the OEM horn circuit (RCT recommends this output be connected to the OEM horn circuit via a relay).
KEY OVERRIDE FUNCTION
The system incorporates a key override in the external circuit so that the system becomes inactive and maintenance can be carried out.
SELF TEST FUNCTION
When the control unit is first powered up, the alarms will self-test for approx. 1-2 seconds.
Light Vehicle Park Brake Module (Part No. 8722)
The 8722 alarm is used in a 12V light duty system. It monitors the handbrake switch and the door frame switch (the door frame switch is the switch mounted in the door frame that switches on the cab light when the door is opened) to provide audible and visual warning if the door is opened while the handbrake is not applied. Once the alarm starts, it stays latched on until the handbrake is applied (even if the door is closed again).
