5 SIGNALLING OUTPUTS AND RELAYS
5.1 SIREN OUTPUT
The control panel has a supervised siren output for the signalling of the alarm condition. This output is controlled
permanently by the control panel and, in case of interruption or short circuit in the connection with the siren, the control
panel generates a fault signal. The siren output, when the control panel is in an alarm condition, can be deactivated
and reactivated again.
The siren output can be excluded from its operation; in this condition, the output is neither activated nor supervised.
5.2 FAULT RELAY
The control panel is equipped with an SPDT form C – dry contact relay to signal the general fault condition managed
as follows:
•
Control panel ON without any fault event:
energised relay
•
Control panel ON with at least one fault event: non-energised relay
•
Control panel OFF:
non-energised relay
The silkscreen in the card is related to the non-energised relay condition.
5.3 OPTIONAL RELAY CARD
The optional modules MR402 and MR404 are equipped with 2 or 4 outputs respectively, with an SPDT form C – dry
contact relay that makes it possible to differentiate among the signals from alarms that come from each zone.
The relay associated to a zone is activated when:
•
The zone goes to alarm condition because of an alarm coming from one device
(zone programmed in single knock mode)
•
The zone goes to alarm condition because of an alarm coming from two or more devices
(zone programmed in double knock mode)
On the optional modules MR402 and MR404, there is also an SPDT form C – dry contact relay output that signals an
alarm condition of any zone of the control panel.
