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.

will turn on for two seconds. The red alert indicator will switch on after the preset period. The ETR

12 | 16
M0030.docx | Rev 1.8 | Modified on 14/06/2019 | © Remote Control Technologies Pty Ltd
output will turn off and the auxiliary output will turn on. The alarm will be active in this state. When the
panel test button is released, the system will revert back to the run state.
d) To check the low cylinder pressure circuit, open circuit the wire at input 1 pressure switch (1200 kPa).
When open, the green alert indicator will switch off, the amber alert indicator will switch on and the
alarm will pulse on and then off. In this state, the alarm will pulse every 30 seconds.
e) To check the cylinder discharged circuit, open circuit the wire at input 2 cylinder discharged pressure
switch. The red alert indicator will switch on and the alarm will be active and pulse for last two seconds
prior to shutdown. Once the shutdown has occurred, the alarm will stay active.
f) Repeat part (e), but push the panel test button during the six-second cycle. This will extend the
shutdown for 20 seconds. During this override period, the alarm will stay active. The delay extension
will only operate once.
g) Once part (f) is performed, insert the key into the key switch and turn to activate it. This will override
the ETR circuit only. The alarm will stay active.
Note
1. Once the system test has been completed, turn the key switch off and ensure all wiring is reconnected to
the original position. Refer to the external wiring diagram in this manual.
2. Once the following has been completed;
a. system has been discharged, or
b. a discharged test has been carried out, AND the ETR output has switched off (shutting down the
machine), then,
the battery power to the unit must be cycled to reset the system.
Turning the ignition on and off WILL NOT RESET the system.
