8. USING SOUNDER DELAYS
8.1 WHAT IS A SOUNDER DELAY
In certain circumstances it may be desirable to have a delay between the panel detecting a fire, and starting its external
sounders, to allow the responsible person to check the cause of the alarm, to stop building evacuation by an obvious false
alarm. If the cause of the Alarm is found to be a true fire hazard, the Delay can be overridden and the Alarm Sounders
activated immediately. Alternatively, in the case of a false alarm, the Panel can be reset.
8.2 SOUNDER DELAY SETTING
On the
Infinity
8 panel, the sounder delay can be programmed on zones 2
– 8 (zone 1 cannot have a delay). That is, all
zones will be delayed by the same amount. The delay can be set between 1 minute and 10 minutes, or the delay can be
left off (sounders activate immediately). Changing the delay time should only be done by the engineer responsible for
setting up the system. But turning the delay on or off can be done by the user.

8.3 HOW THE PANEL INDICATES SOUNDER DELAY
If a Delay has been programmed into the Panel, the General Disablement & DEL(AY) LEDs will be lit. When a zone
processes an alarm signal, the panel will indicate fire in the usual way, but the sounders will not be active until the delay
period has expired. To override this delay, press Delay Override Switch, which will cause the external sounders to
energise. If there is no delay programmed, the Delay Override Switch has no function.
8.4 A FIRE ALARM CONDITION ON A DELAYED PANEL
When an alarm occurs on a Delayed Panel, the panel will: -
Light its General Fire and appropriate Fire Zone light(s)
Sound its Internal buzzer
Start the Delay countdown sequence
Wait until the end of the delay, and then start the sounders.
8.5 OVERRIDING A DELAY IN THE EVENT OF A GENUINE FIRE ALARM
If on investigation the cause of the Alarm is found to be a true fire hazard, pressing the
, will active the Alarm
Sounders and Outputs with immediate effect.
8.6 RESET THE SYSTEM IN THE EVENT OF A FALSE ALARM
If, on investigation, the cause of the Alarm is found to be false, enter the access code and press
button.
