Disclosed is a fire protection system including a plurality of suppressor modules, each having a plurality of extinguishing agent filled suppressor units, an activator associated with each of the units and activatable by electrical current flow to induce release of its extinguishing agent, a series circuit connecting the activators in series, and an initiator circuit for initiating electrical current flow to the activators. A detector responds to the presence of combustion products by activating the initiator circuits in a first plurality of the modules. Also responsive to activation of the initiator circuits in each of the first plurality of modules is a response relay that closes contacts to activate the initiator circuits in another plurality of modules. This in turn energizes additional response relays to close contacts that activate the initiator circuits in an additional plurality of the modules. Sequential activation of the suppressor units in individual modules continues in this manner until all suppressor units in all modules of the system have been activated.
