Update on fitting all battery detectors (my post #11)
I was to replace 1 x 20 year old smoke detector (complete with a 9v battery dated 2015) in the downstairs hallway and a basic CO alarm in the garage for the boiler.
New smoke for here, and another on the landing. Heat detector in the kitchen. Replacement CO in the garage,a nd a new CO in the lounge as there's a coal fire.
Very quick to fit. Just fix the base up with screws, and rotate detector into base to click. Handy if you can find the ceiling joists.
The smoke and heat footprints are slightly smaller than the old smokey I took down, so theres a little painting to tidy up, but at least it covered the old screwholes.
Press and hold the button on the radiolink module one at a time, and each detector connects to each other. The detectors stay in Housecode mode for 30 minutes so plenty time to set them up.
Testing is a 2-person job... but I managed on my own as it was a empty house with no ambient sounds
Tested the detector in the middle of the house and listened as the others started beeping one at a time building up the noise to almost a constant screeching.
The CO detectors also had Audiolink technology. You can set the detector to emit a coded series of loud beeps that a phone app can record, decode and give you information on how many times the detector has been set off. (either through test, or by detected CO)
Think of a 1980's computer loading from a cassette but at the same volume as the detectors' beeping noise.
The difficult bit is trying to convince customers that spending money on these detectors every 10 years is worth it when they can buy a basic one from a supermarket for 20 quid
