The Eaton device barbed isolator unit allows a series of addressable devices to be connected to a master analog loop.

Equipped with a soft-addressed, integrated short-circuit isolator, the device also automatically controls the addressing sequence, allowing plug-and-play installation without the need for fixed addressing.

The device is designed to simplify the installation of remote parts of buildings or to enable simple system expansions by adding all new devices to the fire alarm system panel in a single cable set.
