Abstract
An expansion module for automatic fire alarm system, in shell, the coil of auxiliary reclay is by binding post and 1 secondary passive contact of fire-fighting equipment, the direct current 24V power sources in series of automatic fire alarm system.2 secondary moving together contact of auxiliary reclay are connected with automatic fire alarm system respectively by binding post, interlock with control cabinet secondary circuit.
Description
Art
The utility model relates to a kind of expansion module of automatic fire alarm system, especially expands the module of contact.
Background technology
At present, 280 DEG C of smoke exhaust fire dampers that fire hydrant goes out on the house steward of the low pressure switch on water conduit tube, the flow switch on elevated tank outlet pipe, alarm valve pressure switch, smoke exhaust fan porch only have 1 auxiliary contact, can not meet simultaneously as triggering signal and interlocking signal requirement.Fire alarm system is again without expansion module simultaneously, makes troubles to fire alarm and interlocking.
Summary of the invention
The utility model provides a kind of module of expansion fire-fighting equipment (fire hydrant goes out 280 DEG C of smoke exhaust fire dampers on the house steward of the low pressure switch on water conduit tube, the flow switch on elevated tank outlet pipe, alarm valve pressure switch, smoke exhaust fan porch) contact, brings convenience to fire alarm and interlocking.
The utility model solves the technical scheme that its technical problem adopts: in shell, and the coil of auxiliary reclay is by binding post and 1 secondary passive contact of fire-fighting equipment (fire hydrant goes out 280 DEG C of smoke exhaust fire dampers on the house steward of the low pressure switch on water conduit tube, the flow switch on elevated tank outlet pipe, alarm valve pressure switch, smoke exhaust fan porch), the direct current 24V power sources in series of automatic fire alarm system.2 secondary moving together contact of auxiliary reclay are connected with automatic fire alarm system respectively by binding post, control cabinet (fire hydrant pump, spray pump, smoke exhaust fan control cabinet) secondary circuit interlocking.
The beneficial effects of the utility model are, the utility model adds fire-fighting equipment number of contacts, and 2 secondary moving together contact, without electrical link, can get involved different electric pressure, kind, not cause interference.
