    Hi Sam Here a link to the replacement alarm for Ei151. Harry
  2. Hi First step is to see how old your CO alarm is and whether it needs replacing. Different brands' CO alarms work between 5 and 10 years. There should be a 'replace by' sticker on the unit. Second step is to make sure the batteries are still working correctly. If the CO alarm has replaceable batteries, these might need replacing. Other factors that can set off a CO alarm include boat/car batteries being charged nearby or new floor screed. Harry
  3. Hi Sean, you probably have an ionisation smoke alarm installed (eg EI141 or Ei161). You need the optical version. Simply exchange them on the same base. Here the replacement optical Ei smoke alarm. Harry
  4. Hi Pete, what alarm model do you have? If not sure, can you please send a photo? Harry
  5. With it getting colder at night your backup battery is probably running low giving you a low battery warning. Or your alarm is getting too old (more than 10 years). Step 1: check the age of the alarm. You can find the date on the side or back of your smoke alarm. If it's older than 10 year, you need to replace. Step 2: make sure the backup battery has enough power left Step 3: if none of the above, vacuum the alarm thoroughly to get rid of spider webs etc Step 4: if the above has not helped replace the alarm Harry
  6. Hi, I would guess that it was triggered by the steam from the bath. Most CO or smoke alarms do not work reliably in a bathroom due to the high moisture. Still, worth checking the appliances just to be sure. Harry
  7. Hi Please check replace-by date on the CO alarm to make sure it is not just getting faulty. With both fire alarm and CO alarm in the unit going off, it is unlikely to be a CO leak. However, should the alarm still be in date and the batteries in working condition then you might have to look further into your fuel burning appliances. Harry
  8. Dear Sir/Madam Two possibilities: 1) your power supply does not reach the alarm unit (wrong or interrupted wiring). You can exclude this possibility by switching heads with one of the other units. If the replacement unit also beeps there is a power supply issue. 2) if there is a technical fault the alarm needs replacing. Please contact your seller for an exchange under warranty. Harry
  9. Hi Toni You need a free-swing fire door closer. For example the Fireco Freedor fire door closer and retainer allows the door being used like any normal door but will trigger an integral door closer when a fire breaks out. Harry
  10. Hi, smoke alarms should be replaced every ten years, as beyond that the sensors start to deteriorate. So you were lucky so far. Harry
  11. Hi Sean, these extinguishers have been tested with 35,000 Volt and have to be safe up to this level of voltage. The difference from 35,000 to 1,000 Volt is safety margin to cover the manufacturers against any claims. Harry
  12. Hopefully it is just the screed. It is known to trigger CO alarms. Harry
  13. Hi A technical solution would be to install what is called a 'Free-swing door closer' . These allow a fire door to open and close without any resistance from a normal door closer, however, should there be a fire, the door closer function is activated and the door closes, protecting you from fire in corridors etc. Harry
  14. Hi Tim Our fire door frames are 32mm thick, which is about half an inch thicker than a normal non-fire door frame, so you can expect to lose about one inch in the width of the door leaf. I can only speak about our fire doors, but our glazed fire doors would not work with your proposed sliding mechanism as the wooden edging around the glass protrudes (see image) and would catch. Harry
  15. Hi Pammie, the most likely culprit is a CO alarm with a low battery sitting on a shelve or in a drawer. Neither the cabling nor the base of an EI141 will be able to beep. Harry
  16. Hi, it is definitely not the plate that beeps, as the plate has no sounder. It will be a CO alarm with low battery hidden away in the room somewhere. Harry
  17. Hi Tim, yes, bespoke fire doors with glazing and matching fire door frames can easily be ordered. You need to measure the structural opening (take off architrave first) and then use the configurator to select the finer details of the fire door, such as wood veneer, glazing ect. Harry
  18. Hi Relly The CO9B has a seven year life, so I am afraid your CO alarm will need replacing. Harry
  19. Hi, please have a look if you can identify the replacement date. The alarm might be too old by now and might need to be replaced. Could you post a photo of the alarm? I might then be able to help further. Harry
  20. Hi, the battery is not working any longer. If the alarm is less than ten years old you can contact the manufacturer for a free replacement, as the alarms have a ten year warranty. If it is older you need to replace the smoke alarm unfortunately yourself. As the ST-620 production was stopped a few years ago you need to upgrade to the ST620 replacement alarm, which fits the same base. Harry
  21. Hi Tania, Your case shows how important it is to have CO alarms. With you having high CO levels in your blood and the alarm having gone off, there has most likely been a CO exposure. Sometimes boilers only have short term CO leaks. Short term CO peaks can result from wind and certain weather conditions pushing the fumes of the boiler back down the flue. When a boiler starts up and the flue is cold this can also create short term CO leaks. Has the chimney or flue been been swept this autumn? There could be a physical partial blockage in the flue. Harry
  22. Hi Martin, this is very difficult to answer, as there are many different AFFF chemicals in use. Most of them are harmful, often carcinogenic and yes, if you were encased entirely by foam, you would suffocate. There is, of course, a balance to be made between saving lives from fire and not harming people with chemicals. For fires inside of closed spaces there is sometimes a possibility to use de-ionised water mist extinguishers instead of foam. De-ionised water mist extinguishers can be sprayed directly onto people without harming them (just remember that drinking de-ionised water in significan
  23. Hi Syd Most likely it did its job and detected CO. Sometimes there are spikes in CO (start up of boiler, gust of winds pushing air down a chimney etc) Harry
  24. Hi, that sounds a rather risky advice, how would you ensure that that person is there ALL the time? Why not simply use a fire door retainer that holds a fire door open when required but allows the fire door closer to close the door when there is a fire. These are in very widespread use. Harry
