Quadnet Control Panel Engineering and Commissioning Manual
Alarm Confirmation Delay
The Alarm Confirmation Delay timer allows an automatic reset of an unconfirmed alarm from a
smoke detector.
When a smoke detector using Alarm Confirmation is activated, the sounder within that device (or all the
sounders in the zone) will activate with the sound pattern selected for Alarm Stage 1 (Alarm Confirmation).
This warning sound may also be copied to any additional zone, and may also be displayed on the control
panel if required.
At the end of the Alarm Confirmation Delay time the system will check the detector again to see if the
activation has cleared. If so then the device will reset and no further action need be taken.
The sounder operates during the chosen Alarm Confirmation Delay time, and stops for the final 20 seconds,
during which time the device is reset to check for further smoke presence.
During the Alarm Confirmation Delay, the activation of an additional smoke detector into Alarm
Confirmation will cause the delay time to cease and an instant alarm to be generated.
If, however, the detector is still in alarm then the entire system will go into alarm, operating all the sounders
programmed in the Cause & Effect area.
For a further time period (10 min minus Alarm Confirmation Delay), the activation of the smoke detector will
cause an immediate alarm (depending on the programming of the system Cause & Effect).
The activation of any Heat detector (even in the same device as the smoke detector in Alarm Confirmation)
generates an immediate alarm (depending on the programming of the system Cause & Effect).
Selecting the Devices
Any smoke detectors which are to utilise Alarm Confirmation must be selected using the Quadnet OSP
programming software. Smoke detectors not selected will operate in a standard manner (depending on the
programming of the system Cause & Effect).
An Alarm Stage 1 (Alarm Confirmation) sound pattern must also be selected, and this may be set to a
different sound pattern to that chosen in Alarm Stage 3 (Evacuate) in order to provide and audible
difference between alarm stages.
The activation of any smoke detector set for Alarm Confirmation causes the sounder within that device only
to operate (or across the entire zone if required), but no indication shows on the control panel. This warning
sound may also be copied to any additional zone, and may also be displayed on the control panel if
required.
The activation of any Heat detector (even in the same device as the smoke detector in Alarm Confirmation)
generates an immediate alarm (depending on the programming of the system Cause & Effect).
