Delay-to-alarm status

The delay-to-alarm status indicates that an input
point or detector has exceeded its alarm threshold.
The control panel does not generate an alarm until
the preset delay-to-alarm time ends. If a second
input point, such as a detector in the same software
zone, detects alarm conditions during the delay-to-
alarm state, and the double knock (DK) option has
been programmed for that zone, the control panel
generates an instant alarm.
The control panel generates an instant alarm if it
detects alarm conditions during the night mode,
or if you initiate an alarm from a call point. When
the control panel is in alarm status, it bypasses the
delay-to-alarm.

You can view the information related to the delay-
to-alarm status in point view mode and in zone view
mode.
The point related to the first zone in delay-to-alarm
status is the first point in the zone that becomes
active. For all other zones in delay-to-alarm status,
the related point is the last that becomes active. This
information is updated in real time.
The first point in the delay-to-alarm field contains
the information about the first device that becomes
active. Irrespective of what zone it belongs to, the
last point in the delay-to-alarm field contains the
information about the last activated point.
The following items signal the delay-to-alarm status:
• Control panel display
• LED (1-8) relative zone in delay-to-alarm status
flashing
• Intermittent audible signal on the control panel
buzzer
• Delay-to-alarm output points
During the delay-to-alarm status, you can silence,
investigate, or reset the system, and view the event
log.
