FA6620 Optical Smoke Alarm

Supposed to last until 2033 (10 years), but just failed after just 4 years..... constantly alarms, and won't be silenced, for no reason. Already played up a few weeks ago, and blown out with air, in case it had dust in, but was fine. Soon started again, so had to order new. Is there any comeback for early failure?

Great replacement of old unit. This seems hi -tech, sleek, loud and easily fitted. Tested great and very happy.

Works ok

Item as advertised

This item arrived today being next day delivery on Amazon Prime. My previous alarm was a ST-620 that had lasted the full recommended 10 years, so I decided to replace the alarm in preference to installing a new battery. The unit is compatible with the old fittings, but as a number of reviewers had stated problems with it locking up, I decided to play safe and screw the new base to the ceiling as it's only two screws! I list the positives below. 1. The base had numerous cut-outs for different screw fitting options, so very unlikely it would not replace any previous alarm. 2. The expiry date of the alarm is stated on the rear, if the battery needed replacement it was easily accessed. I did not remove the battery but it was a standard tagged 3v lithium battery, possibly either a 2/3a or a CR123, and was held in with a tie-wrap. I did not check the type for sure, but anyone handy with a soldering iron could replace it. 3. The test alarm was not very loud, so I tried it out with some real smoke. The actual alarm is a lot louder than the test facility. 4. If the alarm sounds, it can be silenced by a press of the test button, so there is no need to wave a towel across it to stop the alarm, which in my case usually goes off when the wife is doing the cooking. 5. It comes with a 5 year guarantee, but I've not put this to the test as it only arrived today. Negatives:- None that I've found so far. Like I said, I did not risk using the old fitting in case it locked into position. I also cannot state the life span of the battery supplied, which in theory should be 10 years, the current price of it's battery is around £4.50. If you do replace the battery, I recommend giving the alarm a good going over with a vacuum, and replacing the entire fitting after 10 years anyway.

I purchased the twin pack and in less than a year both of them gave up the ghost. I contacted Fireangel who sent me replacements. I thought this was great customer service but naturally dissatisfied that the alarms had broken so soon, when they had a supposed 10 year guarantee. One of the replacements has now developed a fault. Unfortunately the chirping sound it gave off really distressed our dog. Luckily my husband was home and able to remove the alarm. I don’t know what would have happened if the dog had been here alone. He was so anxious he was virtually climbing the walls. The worrying fact with the first faulty pair was one alarm chirped once and died. Again we were here to witness this and on testing the alarm found it no longer worked. If we had missed that audible noise we may not have tested the alarm for some time and not realised it wasn’t working. This could have had fatal consequences. I don’t believe these alarms can be trusted with saving someone’s life in the event of a fire. I wouldn’t have give any stars but couldn’t leave a review without checking one of them!

Was easy to fit and works okay I previously had a fire angel SO -601 and was able to use the same ceiling mount for this model

Great product bought to replace previous ond ofcsame make that had been in use for 10 years. Easy to fit and 10 year battery life means you dont need to mess about teplacing batteries
