Why Fire and Gas Detectors are 3-Wire types instead of 2 Wire?
Fire and gas detectors often use a 3-wire system rather than a 2-wire system for better functionality and safety.

2-wire (“loop-powered”) transmitter current loops It is possible to convey electrical power and communicate analog information over the same two
All devices in a 4-20 mA current loop need to be supplied power from somewhere in order to function. Two-wire
