Multi-Area Addressable Releasing Unit

 

Overview

XT+ releasing control units are multi-area releasing control units containing one or two releasing modules complying with UL 864 10th edition.

Up to 15 releasing modules may be connected to a Elite RS fire alarm control panel. Each releasing module can accommodate a separate hazard defined by two specific zones.

Each XT+ unit is equipped with a 5.25 A power supply (120 VAC or 240 VAC) to power releasing modules and attached solenoids / actuators or sequential activators.

Each releasing module has a comprehensive set of inputs and outputs and is configurable via a simple programming interface provided by Loop Explorer 2.

Each releasing module may have up to 7 serially connected Sigma A-SI status units or Sigma A-XT ancillary boards.
