Edwards 517 Series Single Station Smoke Detec- tors feature a solid state piezo signal and a strobe with “FIRE” lettering.
The 517TCS/517TCSB Series provides the 3 pulse temporal pattern evacuation tone as a standard feature. The smoke alarm operates on the light scattering principle, using a pulsing LED light source and a photodiode sensor in a fully screened sensing chamber. Upon activation, the alarm will emit a local audible signal and activate the high intensity strobe.
They are designed for ceiling or wall mounting on a 4″ (102mm) square mounting box using a universal mounting plate, and have a quick- disconnect plug connection.
