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.

Transmitters are available with a wide variety of signal outputs. The 4-20mA analogue signal is by far the most commonly
All devices in a 4-20 mA current loop need to be supplied power from somewhere in order to function. Two-wire
