Networking type smoke alarm principle

Relay output network type smoke alarm from the smoke alarm independent type, it can switch quantity output signal, also called the switch quantity of smoke. Because the signal output, so it can and fire alarm system, and is very suitable for shopping malls, hotels, warehouses and other places. Following a brief for the working principle of couplet net introduce type smoke detector.

The working principle of network alarm type smog

Under normal circumstances, the detector about every 5-6 seconds indicating exhibit of lanterns shiny look. Automatic detection of changes in the environment surrounding the smoke concentration detector, and according to the use environment for automatic sensitivity compensation. When the smoke concentration near the alarm value, the detector to speed up the intelligent operation on the smoke concentration trend, and at the same time the alarm indicator light starts to flash. If the calculation results meet or exceed the alarm value, the detector red LED light remains light, sound, and start the relay output. When the recovery of smoke concentration in the environment to a normal state, the detector automatically return to normal working condition.

Network type smoke alarm alarm process

When the fire occurs, the alarm will monitor the fire signal into a current signal output to the fire alarm controller, the alarm is controlled by a microprocessor controller for fire alarm controller, will take the information stored in the storage, analysis, the central processor operation and judgment processing, confirmation of fire or fault signal, display, start alarm sound and light control circuit to display the corresponding fire alarm, fire detector at time of coding, lighting the corresponding alarm lamp and alarm accordingly, at the same time by the printer to output the fire time and place
