CAST XFP 16 & 32 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL

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 conditions should appear on the System Set-Up Data
Chart on page 20.
In the event of a 1st-stage fire condition (zone dependency or investigation delay):
• the panel's internal sounder will pulse
• the relevant Fire Zone indicator 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 an 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 activating
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.
