8. NOTES ON DELAYS
8.1 WHAT IS A DELAY
A delay can be programmed into the fire alarm panel to postpone the activation of the Alarm Sounders for a
predetermined length of time. The Delay period gives a responsible person time to investigate the cause of an Alarm,
usually in areas which are prone to false alarm (such as waiting rooms filled with smoke) before the building is evacuated.
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 DELAY OPTIONS
All of the Zones of this Fire Alarm Panel can have a Delay applied to them to suit the requirements of the site. The same
Delay period applies to all Zones and is adjustable to a maximum of 9 minutes. The programming of the Delay must only
be carried out by competent service personnel who are advised to record relevant Delay Data on the System Set-up Data
Chart on Page 13 of this User Manual.
8.3 DELAY INDICATION
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 Delay is not programmed, the Delay Override Switch has no function.
8.4 WHAT HAPPENS WHEN THERE IS A FIRE ALARM CONDITION ON A DELAYED PANEL
Should an alarm occur 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, then start the sounders.
8.5 HOW TO OVERRIDE A DELAY IN THE EVENT OF A TRUE FIRE ALARM CONDITION
If on investigation the cause of the Alarm is found to be a true fire hazard, pressing the Delay Override, will active the
Alarm Sounders and Outputs with immediate effect.
8.6 HOW TO RESET THE SYSTEM IN THE EVENT OF A FALSE ALARM
If, on investigation, the cause of the Alarm is found to be false, turn the Key switch to the “Controls Enabled” position and
press reset button.
8.7 HOW TO TURN OFF THE SOUNDER DELAY
There are two ways of turning off the sounder delay:-
1
Return the rotary switch to the 0 position.
2
Turn key to controls enabled position. Press engineer button (to select disablement mode). Press delay override
(the DEL LED will now go off to show that the delay is no longer active). Pressing Delay Override again will toggle the
delay back on.
