Reliable mains powered smoke alarm
on 19 June 2015
I bought this to replace an expired unit the Ei141 which is the older model this is identical but it has the ability to be controlled via the optional remote unit. All these alarms are interchangeable with the "easy fit base". The stock was recent just over 10 years on the expiry date.
Included in the pack are:
The alarm this is covered with a blue "dust cover"
A Duracell 9 volt battery is pre-fitted
2 plasterboard plugs, and 2 screws are supplied
If you are replacing an older unit you can simply swap out the main unit leaving the base in place. I kept the base as a spare just in case it is needed later on.
Instructions are comprehensive and give detailed information on fitting, location for alarms and the detection quality for various types of "fire response" Clear and simple diagrams are shown, wiring is straight forward into the base unit a few notes though a min of 30 cm between the alarm and any obstructions this includes walls or handling lights. For landlords and multi storey buildings clear schematics show a recommended alarm layout indicating the positions, type of alarms and areas where alarms should not be fitted.
Ionisation alarms tend to response better to "fast flaming fires", but they also do quite well with slow starting fires (optical ones are better here) They resist steam and condensation false alarms better than optical units but a more prone to going of with "cooking fumes". Either way I prefer a mix of these alarms one for each floor is considered minimum protection. This alarm will trigger another fitted alarm by the same maker this is a great feature as multiple alarms will sound wherever you are it will be heard. A green light comes on when powered up, a red LED flashes briefly to let you know it's working fine, if the battery is low you get a single "short" beep telling you it's time to replace it, based on the older model I had you should get about 5 years out of one.
Any downsides? Not many the "easy fit" could perhaps be a bit smoother I would advise a larger flat head screwdriver push this in and push it down slightly to help remove the alarm it works but it can take a bit of "jiggling about". Plastics are acceptable they could be a little more robust but they are up to the job. If you are doing any building work or creating lots of dust I would advise removing the alarm to prevent particles contaminating the sensor, once in a while give it a blast with a blower brush to remove accumulated dust. The 9 volt battery is capable of powering the alarm for up to 2 years without mains, it's really there as a back up if the power goes off you are still protected. In the instructions it is clearly stated to use only Duracell batteries rechargeable ones are not really suitable they won't hold the charge long enough so don't skimp here.
A good alarm, not perfect but it's detection rate can't be faulted and the manufacturer has put some effort into ensuring the user knows exactly how to position the alarm and the advantages of specific types of alarms. Recommended
