The Impulse Releasing Module (P/N 10-2748) provides the primary interface between the supervised releasing circuit(s) of a Fike fire suppression system and the Impulse Valve Operator (IVO); which is used to release the fi re suppressant agent from an impulse valve container. The IRM is equipped with three capacitors that receive a constant charging current from the releasing circuit of the control panel. When fully charged, the module is capable of fi ring a single IVO. Upon circuit activation, the output circuit reverses its output voltage polarity, causing the energy in the capacitors to be released to the Impulse Valve Operator. Each IRM is equipped with a red LED to provide positive indication that the module is in the active (release) state.
