performing the disable. This message will then be printed as a
permanent record.
b. During maintenance procedures, a zone input may be disabled so that
the zone may be repaired/tested without its programmed output
occurring.
Input's Message: When a supervised output circuit (bell, horn, strobe
etc.) is activated, the zone reports a supervisory open. This verification
of its operation may not require a message. During an alarm condition
the system automatically disables the verification message of audible
circuits. In cases when doors are monitored for intrusion, it may be
required for your application that door status be reported even in the
access or day mode. In this event, disabling only the input message will
not prevent outputs from occurring based upon the door status, but will
prevent output to the printer and CM1(N) display.
Switch: Switches may be disabled to prevent unauthorized operation
during non-alarm conditions. It may be necessary for your particular
application that HVAC control circuits not be allowed to operate
override functions except during the fire alarm condition. In this case,
the HVAC control switches (located on RASP panel) are normally
disabled and only enabled when an alarm is in the system.
Action: An action is a group of outputs that may be combined as a
function. This output function may be disabled depending upon your
application.
Time Control: Time controls are actions that automatically occur at a
specific time of day. These time controls are typically used for door
control day/night modes, HVAC day/night modes, and lighting control.
During an alarm condition the time controls must be disabled to prevent
a time control from occurring while a fire alarm situation is present in
the system.
Sequences: Sequences may be disabled depending upon status of
specific inputs in the system. If a sequence is disabled, it will not start if
called.
