The alarm sensors are connected to the central alarm station to communicate the occurrence of alarm conditions thereto. The central alarm station includes a priority selector device, a device for establishing a primary notification signal based upon the signals received from the alarm sensors and upon the setting of the priority selector device. The central alarm station also includes a transmitter for transmitting the notification signal to the primary remote stations and a receiver for receiving an acknowledgement signal from the primary remote stations. The primary remote stations each include a receiver for receiving the notification signal, an address detector device, a display device, a response encoder device, and a transmitter for transmitting the acknowledgement signal from the response device. The primary remote stations include another transmitter for transmitting a secondary notification signal to the secondary remote stations. The secondary remote stations include a receiver for receiving this secondary notification signal and also an indicator device and reset device for indicating the reception of the signal from the primary remote station.
