How to find out which smoke alarm sounded first

[Guest pingpong]

Hi

I have interconnecting smoke alarms, but no panel, how can I tell which alarm went off first? I am getting annoying false alarms and to be able to workout why, I need to know which alarm is the culprit.

thanks

Hi Pingpong

I guess you are referring mainly to false alarm.

All quality rf smoke alarms, eg from Ei Electronics and Kidde, identify the unit causing false alarms:

The Ei3100RF range from EI, for example, identifies the alarm with a red light flashing rapidly.

The more advanced range Ei600RF not only identifies the smoke alarm causing the false alarm but also offers a central locator switch which allows you to switch off all alarm sounders with the exception of the alarm having detected a fire/caused a false alarm.

Kind Regards

Hi, we have the UB1RF series and are experiencing false alarms at night or around 2am but can't tell which is triggering the rest off. Do you know how we can tell and how to quiet them all please in one go? They are Radio Interlinked and have no panel.

To silence all of your smoke alarms after ascertaining there is no fire you press the test button. This should silence all smoke alarms. After 10 minutes of the silence button being pressed the detectors will "reset"

As for which smoke alarm initiated the alarm condition the manual is not specific, but I would suggest you look at each smoke alarm and see which one is flashing differently.
