The Releasing Control Module, P/N 55–052/55‐053, provides a means to supervise and control either an agent/impulse release module(s) or a solenoid compatible with the Cheetah Xi. It can only be used for one type of application at one time (either supervising up to six agent/impulse release modules or one solenoid, but never both simultaneously). This module also monitors the external power input for loss of power. The module has a tri‐color LED that will flash a unique color for instant status indication (Green for normal operation, Red for module active, Yellow for device trouble). The isolator version of the module, P/N 55‐053, provides complete short circuit isolation for installations requiring NFPA 72, Class X wiring.
