1ST-STAGE FIRE CONDITIONS
On sites where there is a high incidence of nuisance alarms or where the consequence of a false
alarm could result in the activation of, say, a sprinkler system, the fire officer may have permitted
certain zones to be set up with:-
•
a 1st-Stage
zone dependency function
- to prevent the zone going into full alarm until certain
other events have occurred on the same zone, such as a second device going into alarm; or
•
a 1st-Stage
investigation delay period
- to give the user time to investigate the cause of an
alarm before a full alarm is initiated.
Details of any zones set up with 1st-Stage alarm function will appear on the system set-up data chart
on page 20, provided it has been completed by the system engineer.
In the event of a 1st-Stage fire condition (zone dependency or investigation delay):-
• the panel’s internal sounder (if enabled) will pulse;
• the relevant Fire Zone LED on the panel will flash;
• the panel’s display will show the number and name of the last zone which entered a “1st-Stage”
fire condition (see example below).
If the 1st-Stage alarm is in a zone set up with a zone dependency function:-
Press the
more information
button to display the actual device that has triggered the
1st-stage fire condition (the display will also confirm that the panel is waiting for a
confirmatory signal before going into full alarm). Pressing the
more information
again
will show how long is left before the panel auto-resets (returns to normal mode) should a
confirmatory signal not be received.
If the 1st-Stage alarm is in a zone set up with an investigation delay period:-
Press the
more information
button to display the actual device that has triggered the
1st-stage fire condition (pressing
more information
again will count down how long you
have to invoke the zone’s investigation delay period before it goes into full alarm)
To start the zone’s investigation delay period:-
Enter access level 2 (see page 14) and press the
investigate
button. The period the
investigation delay runs for will be as programmed by the system engineer. Pressing
more
information
after the investigate button has been pressed will display how long is left before
the investigation period expires and the zone goes into full alarm
If upon investigation you discover the fire condition is correct, you can override the delay by activat-
ing any manual call point in that zone.
Should any additional detection device(s) be activated in the zone being investigated during the
recognition or delay periods, the panel will automatically put the zone into full alarm.
Should you discover the fire condition is false, you can silence or reset the 1st-stage fire condition at
access level 2 (see page 14) and take appropriate action to clear the nuisance alarm.
In effect, the 1st-Stage delay on a zone set up for investigation comprises two delays - the initial recognition
period (where the user is expected to acknowledge the delay) followed by the investigation period itself.
