Troubleshooting 45
• An address has been duplicated, that is, assigned to more than one panel.
Access the main menu from the panel. Select Programming , Configuration , View configuration ,
Network
Check the address of each panel in the token-ring network and rectify the error.
• Network circuit open
The token-ring network cabling must be closed properly otherwise the system will be unable to configure
properly.
Check the integrity of the ring cabling, as follows:
- Restore all the panels in the token-ring network to address O.
- Disconnect the network terminals of the SmartLoop/NET board of one of the panels, then check the
continuity of the wiring between the “ D+ ” poles of the A and B ports and between the “ D- ” poles of the
A and B ports and the two “ - ” poles (refer to paragraph 5.1.2 The SmartLoop/NET board ).
10.5.2 Fault on ALARM-A/B terminals
Wiring fault in the emergency alarm ring circuit.
• Check the integrity of the circuit wiring of the panel that generated the event.
Using a multimeter or similar tool, measure the voltage over terminals ALARM-A “ + ” and “ – ”. Under
normal operating conditions the value should be approximately 2.5 V.
- If the value is nearer to 5 V, the connection with terminals ALARM-B “
+ ” and “ - ” of the adjacent control
panel is interrupted.
- If the voltage is nearer to 0 V, there may be a short-circuit between the two poles that connect the
ALARM-A “ + ” and “ - ” terminals of the board concerned with the ALARM-B “ + ” and “ - ” terminals of the
antecedent board.
• Check the integrity of the connection.
Note:
If the emergency alarm loop is not used, it must be disabled via software, otherwise it will signal a
persistent fault condition.
