Product Description
The ANWETECH AT-S210 is a 2-wire photoelectric smoke detector designed to detect smoke at the early stage of a fire, especially smoldering fires. It uses a dedicated infrared sensing chamber with a pair of infrared diodes. When smoke enters the chamber, reflected infrared light increases, and once the smoke concentration reaches the alarm threshold, the detector outputs an alarm signal.
To improve reliability and reduce false alarms, the detector adopts a pulsed emitting circuit, which also helps lower power consumption. The detector features strong environmental adaptability, SMT design, low standby current and a flashing LED power indication with 360-degree visibility.
The AT-S210 is suitable for residential and commercial fire alarm projects, including houses, markets, banks, hotels, factories and warehouses. It is especially suitable for systems that require a stable 2-wire smoke detector with remote LED output capability.
