Sorry for my late contribution. Even taking the fuse out in that section will not resolve the issue, as the alarms will have a backup battery to ensure you are protected in case of a power outage. You can take the entire head off and put it away, which stops the alarms going off because of the smoke machine, however, you are of course not protected against fire in that period. Harry

Hi Steve Here two initial checks: 1) Check that the green LED is on to indicate healthy mains power supply. If not, has the fuse been switched back on? 2) Is there any other alarm in the room (eg a CO alarm)? Sometimes the low battery beep of a CO alarm can be perceived as a low battery beep of a smoke alarm. Failing this you might need to ask an electrician to check the correct wiring of your alarm. Maybe the power supply is not always on live and instead switched by your light switch). Harry

Hi Julie Considering your pregnancy I would not take any risks. I would suggest not to use the boiler until it has been checked by a registered gas engineer or call Gas Emergency Services: 0800 111 999 Harry

You might need to consider adjustable concealed door closers. These are unfortunately quite a bit more expensive than the entry models without adjustment. Harry

Hi While there are interlinked EI CO alarm models available these are very rare. Just replace the batteries in your CO alarm to fix the problem with chirping. If it is a longlife CO alarm with sealed batteries, the whole unit needs to be replaced. Harry

Hi David If the backup battery still has some charge, the alarm will operate safely even if the power supply was off. Harry

Hi David If the green LED is not showing then there a mains failure. It may have tripped at the fuse Board or a loose connection. That’s probably why the Alarm is beeping Harry

Hi Leighton Yes, quite a disputed approach. We have written an article about removal of extinguishers a while ago. Rather than copying in the text, here a link Harry

Hi, I assume you placed it back on the base. If no green light shows the fuse for the power supply might still be switched off or tripped. If that is not the case you sadly need to replace the smoke alarm. Harry

Hi Redders If you press the test button when you have the alarm down from the ceiling it will not test the alarm/s. What it will do is get rid of any small charges that may be left within the unit. You may find that when pressing the test button it may give off a strange sound as the charge is being released, however, it will not go into a full alarm state. Harry

Hi Redders Is the green light on when the alarm is on the ceiling? Harry

Hi Daniel I agree, a fire blanket is in this case not a very helpful solution, as the fire blanket will struggle to exclude air to the burning toaster. While CO2 extinguishers might work, they are generally not that well suited for kitchens. They can blow burning substances out of their containers and struggle with burning dry/porous substances, as they have limited cooling and no soaking capability. A dry water mist extinguisher might be the best solution. These extinguishers are safe on electrical equipment and do not leave any deposit, so are perfect near food. We installed some of these in a hotel chain and soon after one of their customers set a croissant on fire in their toaster. They managed to extinguisher the toaster easily with the water mist extinguisher and after a PAT test, the toaster was back in service. Harry

Hi Lucy Steam from a shower can affect the CO alarm. However, you could, of course, also have a leak from the boiler. It's probably best to stop using the boiler until you had it serviced. Harry

Hi Jeremy, you have probably done so already but please make sure you check the following options first: Is the green light on (showing power supply) and is there no other alarm in the room beeping (eg a CO alarm). If the battery is definitely healthy then it is time to speak with Ei about a return. Harry

An unusual beeping pattern. Most likely the alarms need replacing. Easiest option are the easichange alarm replacements that can be fitted without electrician. Harry

Hi, best to take the alarm off the ceiling and find out if it is a different alarm that beeps (eg a carbon monoxide alarm). This is really quite common, as it is very difficult to detect the direction of an alarm beep. Failing that, make sure that the green power light is on.

Hi Gary some manufacturers, very successfully, use water based CO sensors. The air penetrates a membrane and causes a reaction with the sensor. I have never heard of a CO alarm leak before but maybe you are the unlucky first. I would suggest contacting your retailer about a replacement. Harry

Hi Ollie, please have a look in the room, there will be another alarm, maybe a CO alarm, with a low battery, as the base has no sounder! I hope this helps Harry

Hi Antonio, we used to sell Firetext alarms which sent a signal to your mobile. However, these were discontinued quite a while ago. I am aware of one or two other makes, but don't know enough about them to help. Normal RF alarms only 'talk to each other' rather than with your mobile. Harry

That is right, purely to pressurise the cylinder. Harry

Hi Roo, make sure the fuse is switched off, then remove the alarm head from the base. Watch the removal instructions on http://www.safelincs.co.uk/video_player.php?vid=13 You can then dispose of the alarm. Harry

Hi While it may seem a bit extreme to monitor your house for a pet, the new Nest alarms offer smoke and CO protection as well as cameras, all linked to your mobile phone. Harry

Hi, you would need de-ionised water, a nitrogen cylinder, nitrogen regulator and a Jewel Water Mist refilling adaptor Any problems, please let me know Harry

Hi Erin, I must admit I am not quite sure what an hourly beep would signify. I guess if I knew the model we could check the manual for you. However, I am guessing it is a fault warning and I would suggest you replace the unit with a new CO alarm Harry

Hi Anthony, this sounds very interesting research. Would you be happy to share more information about this work? I feel this could be of general interest for our readers. Harry
