ABSTRACT OF THE DISCLOSURE A multi-zone fire protection system in which each protected zone is provided with a detector for producing an alarm signal in response to the presence of combustion products, a source of fire extinguishing agent, and a pull box station manually operable to induce discharge of the extinguishing agent into the protected zone. Each pull station possesses a signal lamp that can be ener- gized to signal an abnormal condition to personnel present in the area. A signal lamp in a given zone is energized via a central control panel in response to an alarm signal from a detector asso- ciated with that zone, thereby clearly indicating to personnel at hand the specific zone in which a fire has been detected.
