PRODUCT OVERVIEW
The Muirhead
®
Park Brake Warning systems, part numbers 11386 and 11387, are preventative action systems
that not only alert
the operator that the machine’s park brake is not applied, but also alert any personnel within
the vicinity of the machine.
The control unit senses when a door is opened or closed via proximity switches. The 11386 kit has two door
proximity switches whilst the 11387 kit has only one. If
a machine’s door is open, the system alerts the operator
and personnel by means of an audible horn and a instrument panel-mounted LED
that the machine’s park
brake has not been applied. When the machine’s battery isolator is turned on, the system runs through a test
cycle, turning on all outputs for two seconds before returning to its operational state.

OPERATION AND USE
When the park brake warning system is first powered up, the alarms will self-test for approximately one to two
seconds. When the two doors are closed and the park brake is applied, the park brake warning system is in
its armed state.
When the park brake is released and a door is opened, a flashing LED will operate and the OEM horn will
operate repeatedly until the park brake is reset. Simply closing the door will not reset the system. The park
brake will have to be reapplied to reset the system.
When the park brake is applied and a door is opened, this has no effect on the park brake warning system
until the park brake is released.
The park brake warning system has a keyed override (11386 kit only) incorporated in the external circuitry, so
that when the override is turned to the off position, the system becomes inactive to allow for maintenance.
