Description
The Dahua HY-SA20A is a standalone smoke alarm for flats and houses that needs no panel: a photoelectric sensor with split-spectrum technology samples the air every 9 seconds and at a smoke density of 0.2–0.3 dB/m raises an audible (85 dB at 3 m) and visual alarm. In a room up to 8 m high one unit covers 20–40 m², so a single alarm serves a bedroom or hallway. One button handles both test and silence, the green indicator blinks once a minute and the red one marks alarm, fault and low battery. Low standby consumption and SMD electronics keep it running reliably for a long time.
