Installation manual
• 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.
