Smoke alarm selection guide

Smoke alarm, also called fire smoke alarm, smoke sensor, smoke sensor, etc. Powered by the bus, there can be multiple connections on the bus, which are connected to the fire alarm controller and communicated to form an alarm system. There is no sound at the scene when the alarm is issued, and the host has sound and light prompts. This type of smoke alarm device is generally called smoke detection Device. Smoke detectors have address codes and those without address codes.

Ionic smoke alarms are more sensitive to tiny smoke particles, and respond to various smoke energies in a balanced manner; while forward-facing photoelectric smoke alarms are more sensitive to larger smoke particles, and have poor response to gray smoke and black smoke. some. When a raging fire occurs, there will be more tiny particles of smoke in the air, and when it is smoldering, there will be more smoke particles that are slightly larger in the air. If a large number of tiny particles of smoke are produced after a fire, the ion smoke alarm will alarm before the photoelectric smoke alarm. The time interval between these two types of smoke alarms is small, but this type of fire spreads very quickly. It is better to install an ionizing smoke alarm in such places. After another type of smoldering fire occurs, a large number of slightly larger smoke particles are produced. The photoelectric smoke alarm will alarm before the ion smoke alarm. It is recommended to install a photoelectric smoke alarm in such places. If you want to combine the strengths of both, you can install both types of smoke alarms wherever a smoke alarm is required.
