- Q:Smoke alarms keep flashing, and what's the sound?
- Alarm for 10 seconds, to remind the user as soon as possible the scene: alarm for 10 seconds after the green light before disappearing is normal, the alarm signal alarm of different specifications will output different types of alarm: when the gas content in ambient air exceeds the alarm point, the green light before disappearing is normal, stable light emitting light, that work is in the state of monitoring alarm alarm: when the gas content in ambient air exceeds the alarm point: gas alarm
- Q:Smoke LH-94 horn smoke detectors have five lines are the red, black, green, blue, yellow how wiring
- Smoke detectors, also known as smoke detectors, smoke detectors, smoke detectors, smoke detectors and smoke sensors, are mainly used in fire protection systems and are also used in security system construction. It is a typical equipment which is changed from space fire protection to civil use.
- Q:Now, which space program is the prototype of smoke detectors installed in office buildings and residential buildings?
- Smoke detector is a typical equipment which is changed from space fire protection to civil use. In 1970s, NASA engineers designed the Skylab, but if the lab caught fire, it would be a big hassle.
- Q:Why is the smoke alarm always ringing?
- Household smoke alarm is usually installed in the living room or bedroom, study, and some families will install the kitchen or installation location is too close to the kitchen, the kitchen is a much more heat, humidity, smoke alarm installation place, here, not only may produce false alarm, will also affect its service life.

- Q:What is the sense of independence smoke?
- The independent smoke sense is distinguished from the switch smoke sense and the encoded smoke feeling, without external power supply, the 9V battery power supply alone, but at the same time it can not output the signal. Therefore, every independent smoke sensation is a tiny system, and it can be used to remind people when the fire is detected. As we know, so fire hosts must have people on duty, and the independent smoke limitation is very big, she is only suitable for use in small places, an alarm occurs, there must be 10 meters, otherwise it completely lost. Therefore, the independent smoke sense is more suitable for home, shops, other small areas. Coded smoke can protect about 50-80 square meters of space, but independent smoke feels best to install one every 30-40 square meters. If it's a separate room, there is no doubt that every room must be fitted with one.
