-40+120 degree smoke alarm, high and low temperature resistant industrial smoke detector

Description :

　　Product Overview

　　The networked photoelectric smoke and fire detector (hereinafter referred to as the detector) 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

　　Performance Characteristics

　　The detector 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 detector, 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 detector 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 relay output is activated.

　　When the smoke in the environment returns to normal, the detector automatically returns to normal working condition.

　　Self check: Under normal circumstances, press the self check test button to perform internal functional testing on the detector and output the relay.

　　Attention: When the detector alarms, the output relay has passive contacts with contact capacity 1A/24VDC，
