Product Description
The ANWETECH AT-S220 is a standalone photoelectric smoke alarm designed to provide early warning of fire in homes and similar residential spaces. Using photoelectric smoke sensing technology, it responds effectively to smoldering fires and helps give occupants more time to control the fire or evacuate safely.
The detector is powered by a 9V battery and does not require connection to a fire alarm panel, making it simple to install and suitable for residential retrofit projects. During normal standby, the red LED flashes periodically. When smoke is detected, the detector activates an audible alarm and visual indication. A hush function is also included to temporarily suppress nuisance alarms when necessary.
With compact size, low standby current and EN14604 compliance, AT-S220 is suitable for apartments, houses, bedrooms, corridors and other household applications where reliable standalone smoke detection is required.
