Brief Introduction
Sound-light smoke detector can be called detector that particles refraction of the infrared light to detector fire .
The circuit is mainly composed of infrared emission and receiving tube. and the accept tube as for optical maze , optional maze can mixed astigmatism light interference shielding the outside world but will not affect intaking smoke. In smokeless state , the receiving tube only receives the infrared very weak light, when the smoke intakes the detector , it will increase the signal , and when reaching a certain concentration , the detector will output alarm signal.
Functional features
Manual testing , automatic reset .
LED indicator alarm , good to suitable environment,
SMT manufacturing , strong stability .
Product usage:
Suitable for home house , shopping mall , hotel , office , school , bank ,library, computer room and others .
Smoke independent installation site
Installation of high-quality independent automatic smoke alarms in order to prevent the occurrence of major fire incidents, reduce property damage and protect life. National Fire Protection Association report shows, the installation of the recommended number of smoke alarms in the house when the fire broke out, the opportunity to escape than in-house staff is not installed 50% more residential.

Smoke independent installation tips:
Play two 6mm diameter mounting holes on the ceiling apart 60mm (the length of the distance will be a little different smoke difference) position, plastic expansion pipe and screw the detector base, fasten the power cord connector on the battery. The probe in the correct direction button on the base, after pressing tighten clockwise. If the ceiling is installed, be sure to screw the stability, if the cement ceiling, drill drilling required. Also check using a special double-sided adhesive stability.
9V carbon zinc batteries are generally for one year, 9V alkaline batteries and can be used for 3 years; when the smoke of the battery is below 7V, the smoke will be issued by bit ...... voice prompts to replace the battery.
Installation should pay attention away smoke detectors and walls greater than 0.5 m from the outlet more than 1.5 meters, and lighting to maintain a certain distance. Renovation process, you can install smoke base, then fasten the probe is completed until the decoration; lest the renovation process, and other dirt or dust entering the detector, resulting in false positives or damage detectors.
Smoke detector suitable for installation in the following situations:
Under normal circumstances, there are places smoke retention; larger dust, mist, vapor, mist contamination, corrosive gas sites; relative humidity greater than 95%; the ventilation rate is greater than 5M / sec.
In the plant, KTV, hotels, hospitals, shopping malls and other crowded, complex or large areas of space, you need to install a sprinkler can be linked and radio and telephone automatic fire alarm system up.
