6. SOUNDER ACTIVATION DELAY
6.1 DECIDING TO USE A DELAY
A delay of up to ten minutes from the Fire Alarm Panel being triggered, to its Alarm sounder outputs being activated, can be
programmed into the panel by the Engineer. This is a particularly useful feature for schools, nightclubs and other public places
where the nuisance and panic caused by a false alarm must be avoided. It should be noted that the delay period will apply to ALL
DETECTOR zones. Call point Zones will not be delayed.
When a sounder delay is used, zone 1 is designated as a call point zone, and an alarm in this zone will not be delayed. There is an
option to define the last zone as a call point zone also (see section 13: Engineer Options). All other zones will be designated as
detector zones.
When an Alarm occurs on any detector zone, it is processed as normal. However, the activation of the sounders is postponed until
the delay period has expired, thus allowing the cause of the Alarm to be investigated by the User. If the alarm is false the alarm can
be cancelled.

Press
.
5.
The panel will flash a confirmation of the selected delay.
6.
Press
3 times to exit access level 3.
6.3 WIRING CONSIDERATIONS WHEN USING A DELAY
A delay is not usually applied to manual call points, unless there are exceptional circumstances to be taken into consideration.
In order to meet this requirement, call points should be connected to a zone that is not delayed.
On the infinity panel, zone 1 is never delayed, so call points should be connected to zone 1. If more than one 'call point zone' is
needed, the last zone on the panel can also be set as non-delayed by setting configuration dip switch 8 to the on position.
6.4 DELAY INDICATION AND OVERRIDE
If a delay is set, the fire panel will light the Delay (SOUNDER DELAY) LED to indicate that the sounders are delayed. If an alarm
occurs, the fire LEDs will light as usual, but the sounders will not start until the delay period has expired. After the delay period, the
Delay LED will extinguish & the sounders will start.
Pressing the
switch will override the delay at any time and results in the sounders being turned on immediately.
If on investigation, the panel was activated by a false alarm, enter the access code to enable the Controls, and press the reset
button. This will return the system to normal, without the sounders being activated. (Assuming the cause of the false alarm has
been removed).
The delay can be toggled on/off:
1.
Enter access code (1245) press
.
2.
Press
.
3.
Press
again to deactivate sounder delay.
