TROUBLESHOOTING
No LEDs are lit and the LCD shows no text messages.
a) Verify if supply is properly connected to the unit.
b) Verify using a voltmeter that the supply voltage is 24V DC.
The green LED is ON but the LCD shows message “NO COMS TO MAIN PANEL”
This fault is normally associated with a communication fault between the Main Panel and JUNIOR MINI-REP(s).
Press the SILENCE BUZZER button.
The buzzer will stop and the AMBER LED associated with this switch will be OFF.
a) Verify integrity of cables inter-connecting all data loop interfaces.
b) Verify that interfaces are connected to their associated units in the right connector.
c) Verify that
DIL Switches 1 & 2
are placed on the interfaces associated with Repeaters and sub-panels and OFF
on the Main Panel.
Before conducting any verifications on the network wiring or connections between devices in the network,
always remember to completely remove power across the network. The same applies when replacing any
hardware parts on the fire detection system.
Always refer to the installation manuals for technical information.
Do not attempt any hardware repairs without the consent of GFE’s technical department.
If further technical information/ support is required, please contact GFE’s technical support department.
NOTES:
On Main Panel interface DIL Switches 1 & 2 should be removed.
On JUNIOR MINI-REP interface DIL Switches 1 & 2 should be ON.
Interface CON3 should be connected to DATA LOOP
on JUNIOR MINI-REP Main Board.
