Electric Fire Alarm Box and or Fire Detector

A practical, simple and from all reports, effective radio fire alarm signal box system which can function also as a fire detection and alarm system is operating in Westchester County, N. Y.

The device, or devices, are said to be the latest developments of a radio fire alarm system introduced by Safer Electronic Fire Alarm, Inc. of Edgewater, N. J., several years ago.

The system, which utilizes no wires or cables and reportedly can be operated independent of any power wiring, has been on test for some time in the Town of Mamaroneck, Westchester County.

The installation shown in the accompanying photographs and diagrams has been operating between the Bonnie Briar Country Club and the fire headquarters of the Town of Mamaroneck Fire Department, located about one and a half miles distant on Weaver Street.

As illustrated, the system consists of an electronic signal box and antenna, a self-powered transmitting station which automatically transmits a coded signal (the number of the box) when a hook is pulled. Using a different type of selfpowered transmitter actuated by’ a builtin thermal detector, the system can be made to detect a fire, transmit a signal to the receiver which, in turn, activates the coded box signal and through it, sounds a bell alarm in the fire station. In other words, the fire alarm boxes may Ire “pulled” manually or activated automatically by various type detector systems already installed in existing buildings.

At fire headquarters the electronic signal is picked up on a simple antenna and received in the fire alarm office, where tlie coded box signal sets the fire department in motion.

The system has been developed under the direction of Ambrose P. Salmini.

Electronic signal box installed at the Bonnie Briar Country Club in Mamaroneck sends coded messages one and a half miles to fire house where interpretive receiver can instantly identify locations of over a hundred boxes. Each box, a completely seif-powered transmitting station, requires no alarm, phone or power wiring and will operate under disaster conditions. The boxes can be manually pulled or actuated automatically by various type detector systems already installed in existing buildingsAt Mamaroneck fire house, Lieutenant Louis J. Testa holds miniature self-powered transmitter which is actuated by a built-in thermal detector. The other transmitter shown is equipped with a different type thermal detector. Both transmitters electronically send messages to the small receiver shown on the table alongside the signal box
