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 pre-start 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.

Product Overview
The Muirhead®Fire System Status panel, part number 5884, is a unique product that incorporates the following
features:
Figure 1Muirhead®Fire System Status panel, part number 5884
No. Function Description
1. Cylinder Pressure
Correct The alert indicator is green when the cylinder pressure is correct, above 1200 kPa.
2. Cylinder Pressure
Low The alert indicator is amber and will flash when the cylinder pressure is below 1200 but above 900 kPa (the audible alarm will pulse on for one
second every 30 seconds).
3. System Fault The alert indicator
is red when the cylinder is discharged or the
pressure is below 900 kPa. (On initial discharge, the audible alarm will
be on constantly before a two-second pre-shutdown warning period
indicated by the alarm switching from continuous to pulsing.)
The ETR output deactivates whilst the auxiliary output activates.
The red alert indicator flashes when the override is activated.
4. Panel Test / 1 Shot
Override When the cylinder pressure is correct, the panel test button acts as a test button. When the button is pressed, the system will simulate that
the fire system has been set off.
When the cylinder pressure is discharged, the button
acts as an
extension to the six-second delay. When the button is pressed, the
delay will increase by 20 seconds (only once).
5. Key Override
Shutdown Bypass The key switch override will bypass the control unit to allow for machine operation. This switch is to be used in situations where the control unit
requires bypassing, e.g. to move the machine after the fire system has
discharged or when the fire system is empty.
Functions and Features
■Supply voltage 12 to 24 volts dc
■Compact and robust design
■Environmentally sealed – IP65
■Audio and visual indication on reader
■Modular design

Operation and Use
The control unit does not operate while the ignition is not active.
After ignition is applied, the unit pulses the alert indicators and alarm twice to show that they are operating.
The control unit state is displayed by the alert indicators as follows:
■If the cylinder pressure is correct (input 1 closed) and not low (input 2 closed), the green alert indicator
illuminates.
■If the cylinder pressure is okay (input 2 closed) but the low pressure is active (input 1 open), the amber
alert indicator illuminates.
■If the cylinder pressure is discharged (input 2 open), the red alert indicator illuminates. It will then remain
active until the battery power (pin 8) is cycled—cycling power to the ignition input (pin 4) does NOT clear
the red alert indicator.
If the control unit detects that the cylinder pressure is discharged (input 2 open), a timing cycle is initiated. At
the end of the time period (default setting of six seconds), the alarm pulses for two seconds and then the
ignition ETR output is turned off.
The shutdown delay may be adjusted to 15 or 20 seconds.
■If the panel test button is pressed during the six-second cycle, the time delay period is extended by 20
seconds.
■The red alert indicator flashes for this extended period and then the ignition output is turned off.
■This extension can only be applied once.
■If the control unit is shut down after the six-second cycle, the 20-second extension is still available once
only.
The panel test button then has no further effect except that the amber alert indicator illuminates for up to two
seconds to confirm operation.
Note
The test only can be initiated when there is no fault and will illuminate the amber alert indicator for two seconds.
Then, perform a normal shutdown sequence after the programmed time period—the ignition and the green
alert indicator are restored when the panel test button is released.

Installation Guide
1 Install the control unit in a suitable location near the operator.
2 Refer to the wiring table below and the wiring diagram/s 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.

NOTE 1. FOR OFF HIGHWAY TRUCKS (OHT) AND OTHER MACHINES
THAT USE THE C TERMINAL OF THE IGNITION SWITCH;
ENSURE THAT BOTH "AUX CONTROL" WIRES FROM THE
CONTROLLERS ARE CONNECTED AS SHOWN. NOTE THAT THE
C TERMINAL IS DISCONNECTED FROM THE KEY SWITCH
WHEN AUX CONTROL WIRE IS USED AS SHOWN BELOW.
NOTE 2. WHERE THE YELLOW / BLUE AND ORANGE WIRES JOIN,
USE A 2 PIN DEUTSCH PLUG TO MAKE THIS CONNECTION.
NOTE 3. THE IGNITION SWITCH CONNECTIONS ARE MADE BY USING
DEUTSCH PLUGS TO INTERFACE DIRECTLY INTO THE
CATERPILLAR IGNITION SWITCH CONNECTOR PLUG.
NOTE 4. THE IDLE TIMER, EPS AND FIRE CONTROLLER MUST BE
CONNECTED IN THE ORDER AS SHOWN, TO FACILITATE
CORRECT SHUTDOWN PRIORITY SEQUENCE.
NOTE 5. A DIODE IS INSTALLED AS INDICATED WHEN AN EPS
SYSTEM IS INSTALLED.
THE FIRE CONTROLLER RED WIRE CAN BE CONNECTED TO THE
ORANGE WIRE OF THE PRESSURE SWITCH TERMINAL TO AVOID THE
FIRE CONTROLLER TIMING OUT AFTER SIX (6) SECONDS WHEN THE
IGNITION IS SWITCHED OFF.
