GENERAL SAFETY WARNINGS
PERSONAL SAFETY
■Everyone is responsible for safety.
■The installer/service personnel should be trained and authorized to complete the required work.
■Ensure that the machine is safely isolated during installation and testing to protect all personnel.
■Complete all required risk assessments and job safety analysis (JSA) before commencing work.
■Observe all site specific and machine OEM procedures regarding the following:
–working at heights
–working in heat
–working in confined spaces
–all other site specific occupational health and safety (OH&S) procedures
MACHINE
■Carry out all prestart operations as per site and machine OEM procedures.
■Ensure the machine is safely isolated during installation and testing to protect the machine and other
equipment in the area.
■Do not operate any machine with a known fault and report all findings to the supervisor in writing.
■Test and operate machine as per machine OEM and site procedures.
■Read and understand machine and site specific operational and testing instructions.
PRODUCT
Before applying power to the equipment, the user/repairer/ installer must read all product instructions. If in
doubt, seek assistance.
■Ensure electrical connections are made as per RCT’s recommendations. Test circuits prior to connecting
power to any component.
■The equipment contains no user serviceable parts inside. Return the unit to RCT for repairs.
■Retain product and installation instructions for future use.
■Ensure that RCT’s recommended service procedures are included in the machine’s service routine.
■Observe all machine, site and RCT product warnings.
■Follow all machine, site and RCT product operating procedures at all time.
The application of safety should not be limited to the above recommendations.

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
proximityswitches 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.
FEATURES AND FUNCTIONS
Increases operator and workplace safety
Enforces safe operating practices
Multi-voltage 12 to 24 volts
Compact and robust design
Environmentally sealed –IP65
Audio and visual indicators
Door sensing
Park brake sensing
Self-test outputs at startup
Customised circuitry
Override switch
Protects personnel working on and near machine
Helps prevent unattended machine run away accidents
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.

one second).
GREEN –On for normal operation.
INSTALLATION INSTRUCTIONS
1. Mount the control unit in suitable location.
2. Refer to the wiring table below and the wiring diagram in this manual to connect the control unit.
It is recommended that the wiring is installed alongside the OEM wiring ensuring that it is secured at regular
intervals; this will provide protection from heat and abrasion, and any other excess damage that may occur
with extended vehicle operation. When securing the wiring to the OEM wiring, ensure that the loom is away
from moving vehicle parts which could lead to loom damage.
3. Mount the LED on the instrument panel in the cabin clear view of the operator.
