APPLICATION OF FIBER AND THERMAL-SENSITIVE ELEMENTS IN SECURITY AND FIRE ALARM SYSTEMS
Annotation
A series of new magnetically controlled commuting devices for security and fire alarm systems, including fiber-optic and terbium-metallic elements, has been developed. These devices allow expanding the operational and functional capabilities of the element base of automation devices designed for use in modern security systems. The tasks solved by this series of devices include also the expansion of the logical capabilities, increasing the sensitivity, increasing the service life and ensuring the stability of the contact resistance of the switching devices. The devices can be used in development of fire and burglar alarm sensors operating at rated currents of 10 A and higher, as well as in circuits with increased switching power. A modified optical microphone is considered that performs the functions of fire alarm in shipborne optical communication systems. The estimation of static and dynamic errors confirmed the increase in reliability of these devices in comparison with analogues.
