Connecting the fault signalling outputs
The control panel provides a Fault signal output (normally open, non-supervised contact).
Figure 28 - Connecting the fault signal output
During standby status, the 2 terminals will be open. If the control panel detects any type of fault, the two
terminals will close together. The contact can switch a maximum load of 1A - 30V.
Note:
In order to validate the IMQ-SISTEMI DI SICUREZZA certification, this output should not be used as a type
J output (EN 54-1), therefore, it must not be used to command Fault transmission devices.
6.9.1 Wiring
Use NON-shielded cable. The wire section should be compatible with the wire length and load connected to
the output.
6.10 Connecting the Alarm signalling output
Figure 29 - Connecting the Alarm output
The alarm output is a silenceable supervised output protected by a resettable fuse @ 0.9 A.
During standby status the panel will allow a low supervisory current to circulate on the line, with reverse
polarity to that indicated on the board. The diodes connected in series to each load on the line will ensure
that the current closes on the EOL resistor. This current allows the panel to verify cable integrity. Open or
shorted conditions on the wires will generate a fault signal: “
Open”
or “
Shorted alarm output
”.
In the event of an alarm, the output will activate and the panel will supply 24V in accordance with the
polarity indicated on the board.
