4.4.3 Alarm and General Fault Relay
NFS Supra control panel has two voltage free relays (C, NC, NO): Fault and alarm relay.
Alarm relay is activated when an alarm is generated at the control panel (the Alarm
led also turns on). Once activated, it is necessary to reset the control panel in order to
reset the alarm relay and revert it to its normal status
.
The system allows to be configured so that the alarms are verified during a period
of time. If an alarm is not confirmed, the alarm relay will not be activated. Refer to
the operating and zone configuration sections of this manual.
The fault relay is activated in standby and becomes deactivated when a fault is
generated at the control panel or the panel power supply is cut.
Faults may be configured as latched or resettable. By default, faults are latched
and it is necessary to reset the control panel so that the fault relay comes back to
its normal (standby) status. On the other hand, resettable faults automatically
revert the fault relay to its normal (standby) status, in case the fault is cleared.
NFS Supra control panels support 12 additional relays by means of up to three
4-relay boards (VSN-4REL).
Check clause 5.5.1,
Check Special Functions Configuration
section for more information.
Each relay supports 1 A max.
For high current or 240Vac, please use external double relays
with a polarity
diode and a protective diode to avoid return spikes from
coils. See the drawing
below.
