Replace battery in Ei144 heat alarm 

Thank you, 11 year old video. Saved my sanity at 2.30am 👍

The fact that I had to look up a video on RU-vid to see how to take the battery out explains how it is not user friendly.

Thanks. Managed to fix the beep with this instruction at 5 am.

Thank you for the video which is really helpful. However, this unit is not user friendly. I really struggled to get the cover off and when it eventually came off it virtually flew across the room. Now I'm struggling to get the cover back on! Also, it shouldn't need a special tool to open the cover. You need to makes this unit much easier for the consumer to access to change the battery.

Thanks to this video I discovered my tenants had switched all the smoke alarms off at the fuse box .

The cover won’t slide back on no matter what is do it won’t budge back into place. Have followed the correct direction to slide and lined up arrow.

This company is just so helpful and friendly too - I phoned the 0800 number for some advice re my smoke alarm bleeping and the lady that answered the phone was amazing (all resolved now) - thank you!!

I have no idea why the unit itself says pull and not slide! Thanks for your help

As informative as this video is, the product I’d say isn’t that user friendly. I had several attempts at poking my flat head screwdriver in and the cover wouldn’t budge. Then I applied what I felt was slightly too much force and the unit flung across the room and onto a hard floor. I’ve replaced the battery and tested it and the alarms went off loud, and there are no more beeping. Hopefully that’s been enough to solve it. Cheers for the video though, shame you need a tool to open it however.

Are they set to start beeping only at night time?

Does the easy tool come with the heat alarm.

I've followed the steps, manage to change the battery but it's still chirping. What else can I do?

This videos should have said " insert screw driver and press it up the lip" only inserting the screw driver won't release the part and makes it very difficult to take it out. pretty bad system!

Stupid thing keeps beeping, half deaf and tired as hell i took a sledge hammer to the f$&king thing. No more beeping.

0:04 Smoke alarm? It's a heat alarm

The method of removing the cover is almost certainly going to result in damage to the internal plastic clip - making future removals almost impossible. This is exactly what I discovered and I was unable to remove cover for battery replacement . I've contacted local electrician to replace the unit. Very poor design.

0:04 ITZ A HEAT ALARM

I followed the instructions and it is impossible to open it. Also it has a sticker that will need battery replacement in May 2025! Only 3 years out

My alarm looks exactly like this but has no place to put the screwdriver! It really annoying and the worst thing is that we don't even know what company made it because the bit in the middle has gone! And now it's going off every 5 minutes for no reason! It's so annoying! 😡😡

Why didn't you test it

What a piece of shit that opening system is!

This is good and all but it’s a heat alarm, not a smoke alarm!

Safelinics can you tell me how we stop beeping of the fire alarm Also there is a blue light what does this mean

How do we know the battery needs replacing ? mine keeps beeping like an annoying budgie every 35 seconds, and it says battery not replaceable. it has a date on there for 2025, and it's now 2018
