工業企業中現用的火警警报系統是由装在室內或房屋附近的火警警报器、电纜线和保衛所的受警裝置組成的。其中80％左右的費用花在警报系统的綫路上。不久以前,A.尤扎柯夫工程师設計了一种利用原有电話綫路的自动化火警警报系統。这一系統并不影响电話通訊的正常工作,而且对电話系統無須作任何改裝或增装設备。在可能發生火災的房屋中装上标准的自动化火警警报器,而以繼电器和兩对接头与最隣近的电話綫相联接。当發生火災的时候,电話交換台中装設的火警警报器即發出警报,信号灯也开始忽明忽灭。信号灯的警报直到接綫生把火警通知保衛所后才会停止。此外,还發出忽断忽續的电鈴声。 A.尤扎柯夫火警警报系統在兩座电話交换台
The fire alarm system currently in use in industrial enterprises consists of fire alarms, cables and guards installed in or near the premises. About 80% of the cost is spent on the alarm system. Not long ago, A. Yuzhakov engineer designed an automatic fire alarm system that uses the original telephone line. This system does not affect the normal operation of telephone communications, and does not require any modification or addition of equipment to the telephone system. Install a standard automated fire alarm in a house that may have a fire, and connect the relay and two pairs of connectors to the nearest telephone line. In the event of a fire, a fire alarm installed in the telephone exchange was alerted, and the lights started to flicker. The alarm of the signal light will not stop until the operator informs the guard of the fire. In addition, a broken electric bell was issued. A. Yuzhakov fire alarm system in two telephone exchanges
