Wisualarm by Dahua DHI-HY-SA30A autonomic smoke detector
The Wisualarm DHI-HY-SA30A is a self-contained smoke detector for continuous indoor smoke monitoring. Through the split-spectrum sensor technology, the device detects smoke reliably and triggers a loud acoustic alarm with additional optical LED signaling when the alarm level is reached.
The smoke detector is intended for use in households and similar residential areas, for example in single-family houses, apartments and houses. Typical areas of use include living rooms, bedrooms and corridors.
The test and mute function is combined in one central key. The mute function is activated for approximately 12 minutes and can be used to temporarily suppress the alarm in appropriate situations.
The detector works with a low standby current and gives a warning signal with low battery status. The power is supplied by a permanently integrated 3 V CR123A lithium battery; the specified battery life is 10 years.
LED and signal indicator displays inform about standby, alarm, malfunction and low battery status. For a ceiling height of less than 8 m, a protection area of 20 m² to 40 m² is specified for a device.
