    Bespoke Fire Doors

    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

    Ei141 still beeps after battery replacement

    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

    Ei144 wont stop beeping!

    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

    Bespoke Fire Doors

    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
  5. Hi Relly The CO9B has a seven year life, so I am afraid your CO alarm will need replacing. Harry
  6. 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

    beeping smoke alarm

    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
  8. 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.

  9. 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 significant quantity is harmful). Harry
  10. 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

    Can we leave fire exit door open?

    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
  12. Hi George, here some fire rated air vents that we sell. The intumescent material inside swells in a fire and closes off the vent. Harry

    Flashing red twice

    Hi Katy If the alarm has been activated in the last 24 hours, the internal memory is set and the alarm will flash red twice every 40 seconds. After 24 hours this should revert to once every 40 seconds. Harry
  14. Hi Mohan, you just need to remove the alarm from the base and take the battery out. Press the test button to drain the residual power. Here is a video to show you how to remove the Ei141from the ceiling. If you can still hear beeps they will be from a carbon monoxide alarm with a low battery nearby. Harry

    Replacement to Firex i240c

    Hi, this smoke alarm is the replacement for i240c and all you have to replace is the alarm including base. The wiring can stay in place as long as it fulfills general safety requirements. Kind Regards Harry
