F39-EJ1025-D, as an accessory, is a 3-wire smoke detector with fixed temporal alarm sound pattern, which comes with a built-in buzzer and photoelectric smoke detector. It has been widely used in residential and commercial fire control system. Its working principle is fairly simple and effective.

This smoke detector has two light-sensitive sensors that can detect smoke particles. When smoke enters the detector, the sensors detect and convert the smoke particles into electrical signals. These signals are sent to the onboard microcontroller, and then an alarm is triggered once the smoke concentration reaches about 0.2% per ft3. The alarm sound is louder than the background sound and can easily wake up sleepers in the event of a fire.

The F39-EJ1025-D smoke detector also has some additional features such as the photoelectric smoke detector. The photoelectric sensor is able to detect the patterns of smoke particles and alert the user even in conditions where the smoke is not visible to the naked eye. This device also comes with an onboard buzzer which helps emit the audible alarm when the smoke concentration is high.

The F39-EJ1025-D is not only used in residential and commercial fire control system, but also in other industries. It can be used for industrial equipment monitoring, and in security systems. Additionally, it is also suited for applications requiring high reliability such as oil and gas industry, where the chances of fire accidents are more likely. This smoke detector is also used in construction sites, laboratories, hospitals, aircrafts and ships.

In summary, the F39-EJ1025-D is an effective accessory for fire protection. Its simple working principle ensures the safety of occupants in case of an emergency. The additional features, such as the photoelectric smoke detector and built-in buzzer, give it a competitive edge compared to other smoke detectors. Its widespread use in various industries makes it a reliable and efficient fire protection device.
