not interconnecting smoke alarms

galycos

Hi all

I have a few smoke alarms in the house, all interconnected with a backup battery. Model is this one:

https://www.tradesparky.com/fire-and-security/fire-alarm-and-detection-systems/smoke-detectors/hispec-hssapeff10-mains-smoke-alarm

Sometimes (maybe once or twice a year) they may go off (perhaps they get dust or a small insect, no idea) and when they do it is quite annoying as they all go off together making a deafening sound (I am quite sensitive to loud noise) that makes hard for me to go around the house chasing the one that triggered (the one with the red light flashing quickly). This usually also happens at night :D so the entire family wakes up.

My question is, how bad would it be not interconnect them, I mean leaving the interconnect wire out for all? They will still get power from the mains and the backup battery if needed and if one goes off even if it is just one I still will be able to hear it from the back garden with all windows and doors closed (they are quite loud).

Just trying to get peoples thoughts, if that is against some regulation or a silly thing to do.

Thank you.

Yes. The regulation is that they should be interconnected

EI has these

Edit: compatible with EI alarm system

It may be annoying that odd time. But the one time it won't be annoying it'll save your life.

Interconnecting alarms have a far higher probability of saving a families life than a single alarm going off behind a closed kitchen door.

Must be.

Thank you all for your comments. I will leave them interconnected then.

there you go Risteard taken from the building regulations TGDs part B

1.3.6.1

Grades of fire detection and alarm systems

Grade D system: An installation of self-contained mains powered smoke or heat alarms each provided with an integral standby power supply. Where multiple units are provided all devices shall be interconnected so that detection of fire by any one unit will provide an audible alarm from each unit

Smoke alarms and heat alarms should be interconnected so that they all give an audible alarm when any one of them is activated.

and that is taken from technical booklet E for northern ireland
