3.1.1 Fire in Delayed Mode
The DeIayed Mode introduces a delay between an alarm
being detected and the sounders and output modules
activating. Depending upon the panel configuration, this
may be a single delay or a 2-stage delay (an initial brief
delay which may be extended by pressing EXTEND
DELAY to allow an investigation). The delay is initiated if
the panel enters an alarm condition during Delayed Mode.
Note:
For any configured delays, pressing EXTEND
DELAY cancels the initial response time and initiates
the fire investigation period. Activation of an MCP
will also cancel any configured delay period. The
maximum time for the primary initial response time
is 300 secs;
the TOTAL time for both periods is
600 secs
. The delay period can only be configured
at Level 3 by the Commissioning Engineer.
The delayed mode status is indicated on the LCD as below:
1a
When the panel enters a fire condition the delay
countdown is started and the internal buzzer sounds.
The buzzer can be silenced by pressing the MUTE
BUZZER pushbutton. The LCD displays the alarm
information on the top line; this alternates for 1 sec
every 5 secs with the time remaining before the
shortest day mode delay expires.
1b
If the 2-stage delay is configured, pressing the
EXTEND DELAY pushbutton during the primary delay
initiates the fire investigation period.
Note:
If configured to do so, the DISABLEMENT LED is
illuminated (not default) from the initiation of the
primary delay and extinguishes at the end of the
primary delay period or fire investigation period.
2
If the delay time elapses, a full alarm condition is
entered (the configured fire outputs are activated). To
cancel the delay, operate the END DELAY/EVACUATE
pushbutton; the full alarm condition is entered and the
internal buzzer sounds (it can be silenced by pressing
the MUTE BUZZER pushbutton).
Note:
A Fire alarm in a different zone to the first alarm
will also cancel the delay.
3
When the cause of the alarm has been cleared, press
the RESET pushbutton to return to the ‘Status:
NORMAL’ message.
