RS485 Wiring, Communication and Difference with RS232
The commonly used communication method for data acquisition and control is RS485. RS485 is a general communication standard. It can not only link devices to
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.
Our smoke detector uses the 485 connection method, once installed, it can be used normally, avoiding the trouble of removing the cover and replacing the battery. It is an industrial-grade fire detector. This smoke alarm is suitable for a wide range of layouts and requires no maintenance in the later period.Â

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.
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.
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.
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.
