Need to detect ambiant room temp smoke and flame.
temp ok have not found smoke or flame any suggestion?

 

you can find them in catalogues of companies which produce safety fire ... and so on
smoke detectors,you can find wide range of it

How about a Walmart Smoke and Flame ionization
detector for 10 bucks. Or get one of the photoelectrics for smoke and use the ionization for flame. Get the models that slave or simply put a resistor and optoisolator across the piezo beeper. You could probably connect a low voltage
bidirectional PLC input directly. They've got all kinds of UL CIL,yada, yada, certifications and are highly reliable. Or you could get one from the commodity home alarm vendors. Or you can get a special automation model for $1000.00 that
detects "industrial" smoke and flame.
