CFP 2/4/8 ZONE CONVENTIONAL FIRE ALARM PANEL

NOTES ON DELAYS

hat is a delay?

delay can be programmed into the fire 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

ound 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.

Delay options

One, some or all of the zones on the fire 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. fire officer, 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 fire 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 flashing its output delays light

How to override a delay in the event of a true fire alarm condition

• If, on investigation, the cause of the alarm on the delayed zone is found to be a true fire hazard,

pressing the Silence/Activate Sounders button at any time will override the delay and activate the

alarm sounders and outputs with immediate effect.

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 Controls - 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 flashes 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 flash 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.
