Auxiliary Connections
The ViLX-228 Master Station has three auxiliary connections:
Fault is a normally closed volt free relay (30V DC 1A) which
OPENS on any fault, including loss of power.
In Use is a normally open volt free relay (30V DC 1A) connection
which closes when any outstation is operated, see Remote Signal
Display section 7.6 switch settings for further information.
Enable is a normally CLOSED input, and is required to operate the
system. If Jumper J1 is in place, then no connection is required at
the terminals. This function only disables Type B outstations, with Type A outstations and “Assist Call”
emergency assistance alarm systems continuing to operate. It is advised that this feature is not used as
the system should be available at all times, not just during an evacuation. If the feature is used then
the mode LED illuminates yellow after 30 seconds to show that the system is disabled.
