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.
