Product information

Description

DAHUA HY-SA30A-R8 is a photoelectrical reflection smoke detector with wireless interconnection and a built-in 3 V lithium battery. The device uses split-spectrum photoelectric sensing to detect visible smoke particles and triggers an audible and visual alarm when smoke concentration reaches the alarm threshold. With a compact round housing of Ø9.8 cm and height 43.1 mm, and a weight of 138 g, it is TÜV and CE certified and designed for ceiling or surface mounting in homes and small commercial spaces.

Advantages

The smoke detector provides fast response and high sensitivity thanks to its split-spectrum sensor, while the photoelectric detection method reduces the rate of false alarms from steam or cooking fumes. Wireless interconnection capability allows up to 24 devices to operate as a single network so that an alarm on one unit triggers all connected units. The unit incorporates a high-volume buzzer producing over 85 dB(A) at 3 meters, a combined test and silence button, low quiescent current for longer standby life, and a low battery warning. Surface-mount device (SMD) circuit design and a built-in battery simplify installation and maintenance.

Suitable for (tasks / use cases)

  • Residential apartments and single-family homes
  • Small offices and retail spaces
  • Bedrooms, hallways and living areas
  • Multi-room coverage when devices are wirelessly interconnected

Key specifications

  • Detection principle: photoelectrical reflection with split-spectrum sensor
  • Power source: built-in 3 V lithium battery
  • Sound output: >85 dB(A) at 3 m
  • Interconnection: wireless, up to 24 devices
  • Dimensions: diameter 98 mm, height 43.1 mm
  • Weight: 138 g
  • Standby characteristics: low quiescent current consumption
  • Controls: single button for test and silence
  • Certifications: TÜV and CE

How to use

Install the detector on a ceiling or high wall position following local building codes and the manufacturer’s mounting instructions, placing it away from air vents, windows and kitchen cooking areas to reduce false alarms. Power is supplied by the built-in 3 V lithium battery; confirm battery is installed and the unit passes its self-test on first power-up. For interconnected operation, follow the pairing procedure to link up to 24 compatible DAHUA units so that alarms propagate across the network. Use the combined test/silence button to verify operation and to temporarily silence nuisance alarms; a remote infrared controller can also silence a triggered alarm if supported.

Usage recommendations

Place detectors in every sleeping area and on each level of the dwelling, test the unit regularly using the test button, replace units according to the manufacturer’s service life guidance, and respond immediately to any alarm by evacuating occupants and contacting emergency services as required. Avoid painting the detector, exposing it to heavy dust or humidity, and do not obstruct the sensing openings to ensure reliable smoke detection.
