The smoke alarm is actually another name for the smoke or smoke alarm. The smoke alarm realizes fire prevention by monitoring the smoke concentration. The ionic smoke sensor is used internally. The ionic smoke sensor is an advanced technology and works stably Reliable sensors are widely used in various fire alarm systems, and their performance is far better than that of gas thermistors.
Smoke alarms are widely used in fire alarm systems, and are installed in hotels, KTVs, homes, offices, campuses, etc., especially for warehouses, libraries, etc. that are prone to fire. Smoke alarms are classified according to their sensitivity. If it is Class I, smoking in the room can easily cause an alarm; that is, this level is very sensitive. If there is a fire, this level of alarm can leave sufficient time to extinguish the fire. . If it is a III alarm, you can safely smoke in the room alone, but many people smoking together may cause an alarm.
How to keep the smoke alarm from alarming:
Seal the smoke alarm with tape or plastic bag, the smoke sensor cannot receive the smoke information;
Turn off the buzzer, the alarm will not sound, this method is not suitable for linkage fire alarm system;
Remove the smoke alarm. If the wireless independent smoke alarm is no longer needed, you can remove it.
Keeping the smoke alarm from sounding is actually not conducive to fire safety in the room. Try not to use it. It is worth mentioning that most smoke alarms are independent weak current systems, and cutting off the power in the room will not make the smoke alarm inoperative. At present, there are three types of smoke detectors (smoke detectors) in China in terms of sound.
One is the bus intelligent smoke sensor, and the coded smoke sensor in the fire protection system has no buzzer, that is, there is no sound. After the alarm, it will flash and emit signals to the host.
The second is an independent smoke sensor, powered by a 9V battery. Such a smoke sensor must be equipped with a buzzer. When the alarm is issued, there is sound and light on the scene.
The third is that the switch value / relay smoke (multi-line smoke / 4-wire smoke) is mainly used for supporting security systems (anti-theft, monitoring, fire shutter systems, etc.).
This type of smoke sensor manufacturers generally have buzzers before leaving the factory. If no sound is needed, the manufacturers can be asked to remove the buzzer. In fact, when exporting such products, there is no buzzer. Personal operation to remove the buzzer sound, you need to remove the smoke detector, find the buzzer wiring, just cut it. Not recommended for non-professionals.
