Its many programmable features and extensive range of inputs and outputs make the Sigma XT+ ECU coincidence unit suitable for all extinguishing applications where a fully featured control device is required.

Among the many features of the Sigma XT+ ECU are serially connected status units for reduced wiring and reduced installation cost, dual extinguishant outputs that may be configured for main/reserve applications and a countdown timer which displays the time until discharge of the extinguishant in seconds. All units are independently configurable via a simple, code based programming interface to suit the desired application.
