Alarm Confirmation Delay Time
When a detector on a dwelling zone is activated, the integral sounder (or all the sounders on the same
zone if the system is configured to do so) will operate for a pre-determined time period. During this period
the control panel carries out a number of alarm confirmation checks, following which it either silences the
sounders if the detector is no longer in the fire state, or generates a full alarm if the detector is still active.
The number of checks carried out by the panel can be in the range of 1 to 5, with each check period
having a duration of approximately one minute. Therefore the maximum checking period is in the order of 5
minutes during which the local sounder (or all the sounders on the same zone if the systems is configured
to do so) is energised.
If a zone fault is detected during the alarm confirmation time, a full alarm will result.
No alarm is shown at the control panel during the alarm confirmation time, but if indication is required then
the control panel repeater outputs may be configured to become active during this alarm confirmation time
rather than in the normal fire state.
It is not possible to silence the Alarm Confirmation warning sounder during the Alarm Confirmation period
of a delayed zone. In order to silence this warning sounder it is necessary to sound the alarm first with the
‘SOUND ALARMS’ button, and then to silence and reset as during normal operation.
Checkpoint Plus Set-up at Access Level 3 (Engineer)
In the ‘Engineer’ state the panel is still active in detecting fire and fault conditions and will sound the alarm
To Configure the Zone Mode
The ‘ZONE MODE’ function allows the setup of a zone into ‘Local’ or ‘Zonal’ alarm confirmation mode as
follows:
Type Description Zone Fault LED
Instant (normal) All sounders activated in any alarm condition - Factory Default OFF
Delayed (alarm
confirmation)
Multipoint detector will start the alarm confirmation time when in alarm, with either
local or zonal warning sound depending on the setting of the logical Link (Switch 2)
on that device.
ON
1. Press and hold the button
marked ‘ACCESS’
A continuous buzzer tone will start
2. Press the button marked
‘1’
and then release them both.
The continuous buzzer tone will continue.
The ‘ZONE FAULT’ lights will switch on, corresponding to the
mode of that zone, ie lights 1&3 on means that zones 2&4 are
‘Instant (normal)’ and zones 1&3 are ‘Delayed (alarm
confirmation)’.
3. Press the button corresponding
to a zone of which you wish to
change mode, ie, 3 if you wish
to change the state of zone 3.
The continuous buzzer tone will change to an intermittent tone,
and the lights mentioned above will turn off. Your new setting is
now active.
4. Repeat the above sequence
until the ‘ZONE FAULT’ LEDs
(at point 2 above) show the
correct settings for your
requirements,
then;
Press nothing until the system
times out.
The ‘ZONE FAULT’ lights will switch on, corresponding to the
mode of that zone, ie lights 1&3 on means that zones 2&4 are
‘Instant (normal)’ and zones 1&3 are ‘Delayed (alarm
confirmation)’.
The continuous buzzer tone will change to an intermittent tone,
and the lights mentioned above will turn off. The original setting
is still active.
