Ei141 still beeps after battery replacement

Recommended Posts

Guest Thomas NI

Thankyou for your quick reply.

I feel kind of silly now but I was checking the batteries to make sure they matched the type mentioned in the sheets. The batteries were knockoffs, they said duracell on the battery itself but in unbranded cheap packaging. I bought some real batteries and the alarms are now good again.

I have lived in my 7-year-old condo for 1 1/2 years, so had no idea when batteries were last replaced for smoke alarm. In fact I was hoping the alarm was hard-wired only with no battery back-up as I had no ladder. When I got home last night it was beeping loudly. After confirming it took 9V, I drove to Target and bought 2 batteries. When the new battery didn't stop the chirping, I went to bed and listened to chirping all night. Today, I spent ALL DAY reading advice and comments. Finally, I found the correct advice for me. "Make sure the chirping is not coming from another source such as a carbon monoxide detector". BINGO! The two alarms are right next to each other in the hallway, and both have new batteries on the same date which will make changing them easier next time.

Hi, 

We've got a fairly new (just over a year old) E1141RC ionisation smoke alarm, replace by date is December 2026. I've done everything suggested here and in the instruction manual. Tried 2 different Duracell batteries and we still get a beep every 40 seconds or so. Any idea or advice would be welcome!

 

Thanks for your time

Hi

A 40 second beep is the low battery signal so it could be that the replacement battery is also depleted as batteries have a limited shelf life. If your alarms are 3 or 4 years old I would recommend replacing the batteries in all of them to eliminate any confusion as to which alarm is beeping.

Hi, I have 2 x EI141 alarms and the alarm sounded continuously for 5-10 seconds on 1 occurrence then stopped 2 nights ago. Last night the alarm sounded again continuously for 5-10 second then stopped, however then repeated this on several occasions during the night at 1 hour intervals.

At this point I switched off the mains, detached the head & removed the batteries so we wouldn't be woken anymore during the night.

I noticed that the alarms have replacement dates of Feb 2016 so must be older than the 10 years mentioned in previous posts. I will order replacement heads from the links kindly provided on previous posts, however I am interested to know whether the extreme hot weather we are having at the moment could be the cause of the alarms being activated or do the alarms need to detect smoke? Or does the alarms being activated as described suggest they are faulty?

Hi Peter,

Heat will not set off an Ei141 smoke alarm. The false alarms you experienced are probably caused by dust, fibres, a cobweb or an insect inside the smoke chamber. It is just down to the normal wear and tear of the alarms and contamination of the smoke chambers over the years. This is the reason that we recommend replacing the alarms after ten years in service, in order to avoid false alarms.

Hi, I have 2 x ei141 alarms that started chirping. I powered off and replaced the batteries. When powered back on chirping has stopped, I have green light on, but red light is blinking constantly on both units. Is this a fault signal?

Hello Darren you say the red LED is blinking constantly, if the red LED flashes once every 40 seconds (Or close to 40 seconds) this is to indicate that all is well. The green LED is to indicate that mains is present.

As an aside you should also clean your smoke alarms on an as and when basis. A crevice tool (The thin one) on your vacuum cleaner is good for this.
