Major Recall of Edwards 135 Degree Rate of Rise Heat detectors made since 1979

Yes hard to believe but the CPSC  Consumer Products Safety Commission has recalled 85,000 I know number has to be way more more like 850,000 135 Degree Rate of Rise Heat detectors made by the Edwards Company which goes all the way back to 1979  back to almost when I started my business.

They are used in areas like garages and crawlspaces and elevator shafts etc. where a smoke detector would cause false alarms. there pretty simple as far as how they work they trigger and melt off at 135 degrees of heat or  15 Degree temperature change in 5 minutes time and that's the problem the rate of rise unit fails to operate.

This recall goes for all these detectors back to 1979 but Edwards will only pay for and replace units made after  2014

Of course I have questions because there was also a separate company at one time  had products from Edwards and where relabeled and  called API Products?   in 1980s are those recalled also?  Does CPSC even know about those relabeled heats ?

Edwards made for several company's.  I put up a couple hundred of these old heats and I am tracking them down  and replacing them .  I switched over to System Sensor in the 90s s which is a far superior product in my opinion .

But this is not first time heat Detectors have been recalled back in 90s a company called Chemetronics which appears to be out of business had several recalls . One of which I alerted CPSC to as 601 detectors screw terminals would pop off and give no indication detector was not working. 

Thou very simple design  these units play an important part of a total fire protection system. > Especially in areas smoke detectors can not be used.
