You got a lot of rare variants of otherwise common device series series! I was wondering if we can put the chinese SpectrAlert Classics on the System Sensor SpectrAlert Classic page on The Fire Panel Wiki since this would go great as regional differences between each variant of the SpectrAlert Classic.
Do the p700 p900 and p2475rlz led work on sync module like mdl? can they have audible silence? also, can they be coded using sync module? if they can can you send a video all of them (s2475rlz p2475rlz p900 p2475rlzled ) wired on sync module?
none of the LED models will work on MDL module. it is very differently designed compared to the original xenon design circuit wise, the LED models cannot do audible silence because it is 2 wire and does not sync.
Clones do exist but most are addressable and only work with certain locally made panels
