Photoelectric smoke and fire detection alarm

■ Product Overview

The independent photoelectric smoke and fire detection alarm (hereinafter referred to as the alarm) adopts a specially designed infrared photoelectric sensor, a reliable MCU, and SMT surface mount processing technology for production. It has the characteristics of high sensitivity, stability and reliability, low power consumption, beautiful and durable appearance, and easy use. This product is suitable for smoke detection and alarm in factories, homes, shops, computer rooms, warehouses and other places.

■ Product features

The alarm adopts a specially designed photoelectric sensor combined with a reliable MCU, which can effectively detect the smoke generated during the initial smoldering stage or after the fire. When smoke enters the alarm, it causes the light source to scatter, and the light receiving element senses the light intensity. The received light intensity has a certain linear relationship with the smoke concentration. The alarm continuously collects, analyzes, and judges the on-site parameters. When it is confirmed that the light intensity of the on-site data reaches the predetermined threshold, the red LED light of the alarm lights up, the buzzer is activated, and the alarm is triggered by dialing

Phone call, send SMS push notifications to inform the administrator of the alarm information. When the smoke in the environment where the alarm is working disappears, the alarm automatically returns to its normal working state.
