ESL Smoke Detectors False alarm should be included in there name and now there is a Major Recall for 2014 models

Back in the 80's one of the few makers of a lower profile smoke detectors was ESL, Electro Signal laboratory's
Most of the other smoke detectors on the market at the time where what we refereed to as high hats which stood 5-6 " off ceiling while the low profile ESL was 2" 

My customers like many other alarm company customers wanted the lower profile units they just looked better and while some of the ESL smokes I installed have behaved and never falsed this was not the normal seems they worked for a couple years and then nothing but false alarm problems.

One big problem I found was the silver metal heat detector on the unis which triggered from static electric and radio frequencies if they where strong. but even the not heat detector units false alarmed as well.
So like other company's I put the practice in place of  if an ESL smoke falsed it was replaced with a System Sensor smoke which where very stable.
In the 90's ESL was bought and sold several times and they came out with a new design suppose to stop false alarms and while they had a better track record they still had problems the few I tested again some worked fine others just falsed. So I will no longer install them .

The units are still made but now they have had to have a major recall of units made in 2014 after it was found they will not activate in some cases.
