Double beams of the fire alarm system

Full name of the radio-infrared "beam breaker-type sensors" (Photoelectric Beam Detector), its basic structure, including target hole, the beam intensity of light, spherical lens, LED light and so on. Its detection principle Naishi by using infrared LED infrared light-emitting diodes, and then by focusing processing optical mirror to do to make the light spread to a very remote from the acceptance by the optical device. When the light is interdict will be issued when the alarm. Infrared is a non-visible light, but will spread out will form a cone projecting beam. No intermittently issued a second infrared light beam 1000, so is the pulsating infrared beam. Thus they can not be transferred to the radio is very remote (600 meters).
Trip means the use of the beam across the detector when someone had control protection zone, Trip invisible infrared beam and trigger alarms. Commonly used for outdoor wall alarm, it is always in pairs: a launch, a receiver. Transmitter emits a beam one or more of the human eye can not see infrared light, the formation of the warning line, there is an object through the light was blocked, the receiver changes the signal, amplified after treatment alarm. Infrared sensor on the radio to select the appropriate response time: too short and easily lead to unnecessary interference, such as the birds fly, small animals pass through, etc.; too long to occur omitted. Usually 10 m / sec to determine the shortest time shading. If the person with a width of 20 cm, then the shortest Trip time is 20 ms. Is greater than 20 ms alarm, no alarm is less than 20 milliseconds.

Double-beam on the radio alarm widely used in urban security, residential, factories, companies, schools, families, villas, warehouses, resources, petroleum, chemical, gas transmission and distribution and many other fields.

Double-beam on the radio alarm - Features
