number of reasons. Some of them are:
Main power failure for an extended period of time during which the batteries have •
been depleted.
Blown main board fuse.•
Other malfunction of the power supply, main board disconnected from PSU (power •
supply unit) etc.
Blinking power indicator signies one of the following :
(a) Removal or power loss of the batteries.
(b) Main power loss.
(c) Blown main power fuse or PSU fuse.
In the above cases, SYSTEM FAULT indicator turns ON and the on board buzzer sounds
continuously.
2.1.1 Battery faults
The Matrix2000 panel uses a battery fault detection system that will generate a battery
fault indication in the following cases:
Battery missing.•
Battery wiring open circuit.•
Battery not able to charge (low voltage).•
Battery wear (increased internal resistance of batteries).•
2.2 System FAULT indication (General Fault)
GENERAL FAULT, indicates a problem in the system. It turns ON in case of:
Zone wiring connection problems,•
Signalling devices output wiring problems •
Relays outputs wiring problems (auxiliary relays MER4 or MER8). •
Auxiliary power faults•
Earth fault condition•
The above mentioned problems could be open circuits, shorts between wires or shorts
between wires and earth.
Consequently the Fault relay output is activated. At the same time there will be a continu-
ous audible notication from the on board Buzzer.
It is possible to silence the Buzzer by pressing the SILENCE key, with the keyswitch in
position Control Enable.
When the problems causing the indication are restored all the above indications will turn
off automatically.
