Reduce false alarms with Alarm Verification on the Infinity ID2

Verification is an option included on the Infinity ID2. Verification is intended for systems in apartments, HMO’s, or any premises where it may be desirable that an alarm from a smoke detector from one apartment or area would need to be confirmed before the whole system goes into alarm.

There are two different settings for verification;

• Device verification – with this setting, an alarm will just operate the sounder connected to that detector.
• Zonal verification – with this setting, an alarm will operate all sounders in that zone set to zonal verification.

How verification works

The verification function works as follows;

1. Any smoke detector on the system can be set to verify an alarm. (Not that an opto-heat detector is treated as a smoke detector for verification, whether the alarm is caused by smoke or heat).
2. If a detector with the verification setting senses smoke, the detector alarm LED will turn on. If the detector has an associated sounder base, the sounder will turn on with the Alert tone (i.e. pulsed) rather than the Evacuate tone. The ID2 panel`s screen will show “Confirming alarm”.
3. If the device in alarm has zonal verification set, the panel will turn on the sounders of all other detectors set to zonal verification in that zone.
4. If the detector drops below the alarm level within the programmed verification time (1 minute to 3 minutes 45 seconds), the sounder will turn off, but the panel will continue displaying “Confirming Alarm” for at least 5 minutes. The buzzer will also continue to operate as long as the “Confirming Alarm” message is displayed.
5. If the detector stays in alarm by the end of the verification delay, the system will go into full alarm.
6. If another detector WITHOUT verification setting or a call point goes into alarm, the panel will go straight into full alarm.

Setting the verification

The verification time can be set between 60 seconds and 225 seconds.

Step 3

• Once the time is selected you can then set the verification delay on the desired smoke detectors.
• To set the verification delay on the detectors, go to Engineer menu 2 and select option 4 for Alarm Verify.
• Select option 2 for choose device.
