## Long description

WisuAlarm DHI-HY-SA30A is a photoelectric reflection smoke detector designed for wireless fire detection in homes, apartments and small commercial spaces. The unit operates on a 3 V lithium battery and incorporates split‑spectrum optical sensing to detect visible and partly obscured smoke particles. Compact and lightweight, the detector has a diameter of 98 mm and a depth of 43.1 mm, providing unobtrusive ceiling or wall mounting while delivering audible and visual alerts when smoke concentration reaches the alarm threshold. The device meets TÜV and CE certification standards for safety and performance.
Advantages
The detector uses split‑spectrum sensor technology to improve sensitivity to a wider range of smoke particle sizes while reducing false alarms. A combined test and hush button simplifies routine testing and temporary silencing of nuisance alarms. The built‑in high‑volume buzzer produces an output above 85 dB(A) at 3 meters to ensure the audible alarm is noticeable. Low quiescent current consumption and a low battery warning extend operational life and prompt timely replacement of the battery.
Suitable for
 Homes and apartments where battery‑powered detection is preferred
 Small offices and commercial rooms without centralized fire detection
 Rental properties and locations requiring easy installation and relocation
 Rooms with low to moderate dust where photoelectric detection is effective

How to use
Install the detector on a ceiling or high on a wall according to local fire safety guidance, avoiding corners, air vents and areas near kitchens where steam or cooking smoke can cause nuisance alarms. Press the combined test/hush button to check operation and to temporarily silence a non‑critical alarm. Replace the battery as indicated by the low battery warning and follow manufacturer instructions for safe disposal of the spent battery. Perform periodic functional tests to confirm the optical sensor and buzzer operate correctly.
Usage recommendations
Place detectors in each sleeping area and on every floor for comprehensive coverage, keep units free of paint and dust, and do not install directly above stoves or heaters. Test monthly and replace the device or battery according to the manufacturer’s specified service life to ensure reliable smoke monitoring.
