The smoke detector 30 is of an ion smoke-sensitive type, contains a small amount of radioactive substances in the ionization chamber, can enable the air in the ionization chamber to be a conductor, allows a certain current to pass through the air between two electrodes, enables local air to be in an ionization state through rays, and forms an ion flow through the action of voltage, so that effective conductivity is provided for the ionization chamber. As the smoke particles enter the ionization region, they reduce the conductivity of the air by engaging ions, creating a reduction in ion travel. When the conductivity is below a predetermined value, an alarm is issued.

The smoke detector 30 may also be of the photo-inductive smoke type, also a point type, developed using the basic property that smoke generated on fire can change the propagation characteristics of light. According to the absorption and scattering effect of the smoke particles on the light. The photoelectric smoke detector is divided into a shading type and an astigmatism type.

The smoke detector 30 may also be of the infrared beam smoke sensing type, a line detector, a fire detector that responds to smoke parameters around a linear strip within an alert range. The linear smoke detector is divided into two independent parts, which are installed at two opposite positions and connected by light beam. The infrared beam smoke detector is divided into a counter-emitting type and a reflection type.

The smoke-sensing fire detector is suitable for being installed in places where smoke is generated greatly or flame retardance is easy to generate after a fire disaster occurs; it is not suitable for being installed in places with larger smoke or higher ventilation speed at ordinary times.

After alarming, a pair of relay passive contact signals (normally open and normally closed and jumper setting) can be output for controlling ventilation equipment or providing normally open or normally closed alarm contacts for other equipment. When the concentration of combustible gas in the environment reaches a set threshold value, an audible and visual alarm signal can be sent out, and a relay passive contact signal can be output. When the concentration of combustible gas in the surrounding environment is reduced to be lower than a response threshold value, the detector in the alarm state automatically restores to a normal working state.
