Yea but that doesn't seem to be compatible with any system looking at the charts. While I can't swear to it, the only difference in the two is the sounder and I fail to see how that would make it incompatible except if the current draw from the sounder would overload the panel or something which I don't think it would. Of course HAI would have to say this for sure but I don't see anything wrong with it. Elk only states the same non 'A' model as compatible and my existing 2WTA-Bs work fine.
Agreed. And yes, they are listed as compatible.
I have to chime in again and say that you really need to consider do you want to use a detector unless you have verified it is compatible with the panel? Did you check the installation instructions to see if the detector is on the list of 2 wire detectors for the panel you have?
This is life safety and you do not want to have a situation where the detector does not operate because of a compatibility issue.
Steve the System Sensor Detectors with sounders are NOT on the list as compatible. I thought that was the detector in question. If I am mistaken sorry.
I have the system sensor specs for the 2WB and the 2WBT-A at work. I am 99% sure the specs are NOT the same.
The System Sensor Detector with sounder is compatible with the following per the System Sensor website. I know for a fact it is incomplete since I personally had UL test this detector with several panels a few years ago that are not on the list.
