Smoke alarm

[malagabob]

My son tells me via telephone that his smoke alarm is beeping every 30 seconds or so. I told him to change the battery. He has looked and has told me there is no battery but wired through the ceiling.

[ummmm]

It should have batteries as a back up. Try putting some in.

I thought that mains wired ones had a battery as backup.

Our wired in one has a back up battery, and it took me ages to work out how to open it.

The make we have has a slot on one side marked by an arrow.

You push a small screwdriver into the slot, and slide the smoke detector sideways off the baseplate.

Mine is similar to Hopkirks, inasmuch as the battery is in a sliding drwaer underneath the alarm unit.

There must be a battery in your son's, otherwise it wouldn't beep at a regular interval.

[boxtops]

must be the backup battery

[Prudie]

Ours has a battery in the control box on the wall. There must be a back-up battery somewhere or it wouldn't work in a power cut.

Just had a look at it for him. Its a Kidie make, and a sticker on the inside face says battery cannot be changed.

did he get it fitted by the fire service? they fit them in our area and come out after 10 years to do a check..... he ought to call whoever fitted them maybe if you cant change or get to the battery...
