Fault Mode - JSG M2AP01 Operation & Installation Manual

FAULT MODE

The Alarm Panel is able to detect a number of faults conditions. Most fault conditions are latched and can only be
cleared by pressing the TEST button. This ensures that intermittent faults do not go unnoticed. Once a fault is latched
the appropriate indicator will blink and the audible alarm will give a short pip every 3 seconds and the OK indicator will
be off. Should the fault clear by itself (for example an intermittent open circuit) the OK led will indicate that the panel is
now functioning correctly but the appropriate red indicator will remain lit until cleared by pressing the TEST button.
REPLACE BATTERY
Indicates the battery is due for replacement. Note that if the OK indicator remains lit the battery still has enough charge
for the Alarm Panel to function correctly but should be replaced at the first opportunity. If the OK indicator is off then
the battery is critical and the panel can no longer function correctly, the battery must be replaced immediately.
OVER/UNDER PRESSURE
Indicates that the pressure in the system is either below 9 bar or above 16 bar.
SYSTEM FAULT
Indicates there is an electrical fault. On the pressure transducer circuit the Alarm Panel will detect a short or open
circuit as well as incorrectly wired or faulty pressure transducers. In MusterWire LHD installations the panel will also
detect if there is a fault with the release solenoid.
On the detection circuit the panel will detect an open circuit and a missing or faulty Resistor Plug (M2RP01).
TEST FUNCTION: Briefly pressing the TEST button will activate (test) the buzzer and all LEDs. All latched faults will be
cleared and all circuits will be tested – any faults still detected will be latched and indicated. Use this button to clear
any faults after they have been corrected.
FIRE MODE
The Alarm Panel will behave differently depending on the type of installation:
MUTE FUNCTION: In FIRE MODE once the panel has completed the SHUTDOWN sequence will the MUTE function be
enabled to allow the alarm to be silenced.
