FIELD: physics.
SUBSTANCE: installation and operational control cover switch modes of automatic firefighting system control circuits; centralised control of functional state of each targeted fire call point in the fire alarm system; fast fire localisation and beginning of firefighting operation; uninterrupted operation of targeted fire alarm system even in the case of failure of one targeted fire call point; registration and storage of up to 1000 alarm instances happened within a detection period in the energy-independent memory of electronic drive circuit.
EFFECT: improved reliability and maintenance convenience of the device.
