14.3 Full and Local Alarms on the SPC
The type of alarms generated by the SPC system can vary depending on the type
of zone that triggered the alarm activation. The vast majority of alarms require a
visual (Strobe) and audible (Bell) indication of an intrusion to the premises or
building.
By default, the first 3 physical outputs on the SPC4000 Controller are assigned to
the External Bell, Internal Bell, and External Bell Strobe. When activated, these 3
outputs together provide sufficient warning of an alarm condition to persons located
inside or within the immediate environment of the building or premises where the
intrusion has taken place.
Full and local alarms on the SPC activate the following physical outputs:
z
Controller Output 1: External Bell
z
Controller Output 2: Internal Bell
z
Controller Output 3: Strobe
For details on how to wire the bells and strobe see Section 7, Wiring the System.
A
Full Alarm
activation reports the alarm to the Alarm Receiving Centre (ARC) if
one has been configured on the system.
A
Local Alarm
activation does not attempt to call the ARC even if one has already
been configured.
A
Silent Alarm
activation does not activate outputs 1 – 3 (no visual or audible
indications of the alarm). The alarm event is reported to the ARC. Silent alarms are
only generated when alarm zones with the Silent attribute have been opened when
the system is set.
