2 Wire Addressable

Tocsin 650 & 750


IGD’s 2-wire gas detection system is cheaper and faster to install. IGD’s 2-wire systems utilise 2 core cables for both power and communication. This minimises the number of cable cores and ultimately cutting down on the cost of install. Cable cores on IGD 2-wire systems have no polarity. This both minimises the possibility of mis-connection and speeds up the install time.
