Smoke Detector RS485

It is a device that uses the photoelectric principle to detect the smoke generated during a fire. The accuracy of photoelectric smoke detectors usually does not cause so many false alarms. This smoke detector is installed through wiring, which avoids the late-night call caused by battery replacement. The alarm uses photoelectric smoke devices and excellent production technology, stable work, simple installation, no need to debug.

Why buy a smoke alarm?

As the number of users of smoke alarms continues to increase, the number of deaths caused by residential fires is also declining. Studies have shown that in the event of a fire, the chances of escape for people in residences with smoke alarms installed will be 50% higher than that of residences without installations. It is necessary to install an alarm in every bedroom.

What are the types of smoke alarms?

There are 2 types of smoke alarm technology-ionization and photoelectric. Ionization smoke alarms usually have a stronger response to flame burning (such as pan fires or smoke produced during cooking). Photoelectric alarms are usually more sensitive to smoldering fires, such as cigarettes, overheating of electrical wires, or high temperatures similar to space heaters.

Where to install smoke detector?

The smoke detector installs inside and outside the sleeping area. Install a smoke sensor for every 60 square meters indoors (the specific area depends on the coverage of the smoke sensor), and install the smoke sensor 0.5-2.5 meters above the important equipment. The smoke sensor in the corridor is installed every 15 meters.

How to clean smoke detector?

The smoke alarm should be cleaned every 3 years, and the cleaning should be done by professional technicians. Usually, you can wipe the shell with a soft cloth.
