  1. Hi here is a helpguide for anybody experiencing problems with Aico/Ei alarms Can you please send a photo of the red light on the side? Is it a setup using an RF base? KHarry
  2. Hi Adrian, not sure if have understood the full picture. However, if you are looking for a concealed fire door closer that offers protection from the user being trapped by the fire door, I could recommend the Powermatic from Perko. This fire door closer is concealed but more importantly is a free-swing door closer which allows the fire door to operate like an ordinary, closer-free door. When the fire alarm system trigger the fire door is of course shut automatically. Harry
  3. Hi Sarah, switching the alarm off at the fuse makes things worse as the alarm not only has a low battery warning but also ants to tell you about the power interruption. The best approach is to either change the backup batteries once a year as a pre-emptive step or to change your alarms to smoke alarms with trickle charging of the batteries. If you currently have the Ei140 series (with alkaline batteries) you can buy new Easichange Ei160 series alarm heads which slide staright onto the existing base and have trickle-charged backup batteries that last the entire life of the alarm. Harry
  4. Hi Heather, sadly, there are no more Ei alarms being produced with the same base plate. You will need to upgrade with this replacement kit, using the same wiring plus a plate that covers the unsighly mark left by the old alarm. Harry
  5. Hi Graham Just for information. Safelincs offers nationwide fire door install by certified installers. Harry

    Hi, if you need quantity info you could either message me your plans for our engineers to have a look at or you could post the siteplan in the forum for us to answer the question in the open. Harry
  7. Hi, what alarms are in your system. I assume these are simpy mains powered interlinked smoke alarms? Please send a photo.

    Hi, as long as it is a water mist extinguisher with de-ionised water it can replace both the foam and the CO2 and would actually be more appropriate in an office. Please remember: You still have to have certain minimum numbers per floor in accordance with the British Standards. Benefits: - It is a very easy to use extinguisher and staff only require training for one type of extinguisher which reduces the risk of confusion - Water mist extinguishers (with de-ionised water) do not conduct any electricity and are safe even on live electrical equipment (up to 1000V) - De-ionised water does not leave any residue (foam, on the other hand, is hard to clean up and lightly carcinogenic) - Water mist actually clears the air of smoke and builds up a heat buffer in front of the user - The environmental impact is reduced, as de-ionised water is, well, just purest water. There are no chemicals in de-ionised water mist extinguishers I hope this helps Harry
  9. Hi Shree Wedging fire doors is a huge No-No at any time, as you never know when a fire could break out! Fire doors help to compartmentalise and hold back fires and allow the safe evacuation of people but will only work if they are closed when the fire starts. However, there are simply ways to hold fire doors open in a legal way. Fire door retainers hold fire doors open during normal operation and allow the door to close in case the fire alarm goes off. If you want the fire doors to behave like normal doors (without the closing pressure from the overhead door closer) you need a free-swing fire door closer. These closers are fitted instead of the traditional overhead fire door closers. Again, when the fire alarm goes off, these free-swing devices will close the door. Harry
  10. Hi Emily, smoke and heat alarms love to go off in the middle of the night when the temperature is at its lowest and the backup battery voltage drops as a result of the low temperatures. If your battery is on the end of its lifespan, this is one way - but a very painful way - of finding out. I would recommend that you pro-actively exchange batteries every year or two to avoid this. You ought to check the age of the heat alarm. The alarms need replacing every ten years otherwise they can become erratic. See here how to remove the alarm and check the age. There is a replacement alarm for the Ei144 heat alarm. Harry
  11. Hi Jenny, while I cannot advise on whether you have a CO leak or not I can state that a few years ago most CO alarms had only life expectations of 5 to 7 years. It should state on the side or back of the alarm when it needs replacing. Once expired, CO alarms become unreliable and might go off for no reason. These days most CO alarms come with 10 year life. Harry
  12. Hi, unfortunately, you need to replace the unit AND the base. The good news is that there is a compatible replacement kit with a pattress that covers the unsightly stain left form the original alarm's footprint. Harry
  13. Hi Liz, I would say that your sensor chamber got somewhat contaminated. Try to vacuum around the slots of the alarm with a soft brush attachment. If that does not help you ought to replace the alarm head which can be done easily without an electrician. Harry
  14. Hi Georgia, make sure there were no fuel burning appliances on in your house or in the neighbouring property (carbon monoxide can leak through cracks and shared chimneys). If these were not the cause of the CO alarm, then this first cold night might have triggered a low battery alarm. Harry
