NOTES ON DELAYS
What is a delay?
A delay can be programmed into the fi re alarm panel to postpone the activation of the alarm sounders and other outputs 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 vehicle exhaust smoke in a loading bay) before the building is evacuated. If
the cause of the alarm is found to be a true fi re hazard, the delay can be overridden and the alarm sounders activated immedi-
ately.
Alternatively, in the case of a false alarm, the panel can be reset.
Delay options
One, some or all of the zones on the fi re alarm panel can have a delay applied to them to suit the requirements of the site. The
same delay period applies to all delayed zones and is adjustable to a maximum of 10 minutes. The programming of delays
must only be carried out by competent service personnel who are advised to record all relevant delay data on the System Set-
Up Data Chart (page 13) of this user manual. Delays should only be used with the prior knowledge and consent of all relevant
authorities, i.e. fi re offi
cer, building control, etc.
Delay indication
If delays have been programmed into the panel the Output Delays light and the General Disablement light will be lit steady.
This means the immediate turning on of the alarm sounders and other outputs on one or more zones has been disabled. The
only way to ascertain which zones have been programmed with a delay is to refer to the System Set-Up Data Chart (page 13)
What happens when there is a fi re alarm condition on a delayed zone?
Should an alarm occur on a delayed zone, the panel will:
• Flash its General Fire and appropriate Fire Zone light(s)
• Sound its internal sounder
• Start the delay countdown sequence
• Indicate a delay is running by fl ashing its Output Delays light
How to override a delay in the event of a true fi re alarm condition
• If, on investigation, the cause of the alarm on the delayed zone is found to be a true fi re hazard, pressing the Silence/Resound
Sounders button at any time will override the delay and activate the alarm sounders and outputs with immediate eff ect.
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, put the panel into access level two
(see Authorised User Con-
trols - page 6) and press the Control Panel Reset button.
How to turn the delays function on or off
Any delays that have been programmed into the panel can be turned on or off by putting the panel into access level two and
following the disablement/enablement selection process as described on pages 10 and 11.
Selecting the Output Delays option and then pressing the Enable/Disable button so that the Output
Delays light fl ashes in synchronisation with the General Disablement light shows that the delays are on.
Pressing the Enable/Disable button again will make the Output Delays light fl ash slower than the General
Disablement light, showing that the delays are off .
Having chosen the desired setting, pressing the Next Option button will exit the disablement/enablement selection process.
The Output Delays light will now be lit steady with the
General Disablement light, showing that delays are on, or the Output Delays light will be off , showing that delays are off .
