## Long description

DAHUA HY-SA2FA wireless photoelectric smoke alarm is a battery-powered smoke detector designed to detect smouldering and visible fires at an early stage. The device uses a photoelectric sensor to identify smoke particles and triggers a local audible alert while also communicating wirelessly with compatible alarm control panels. It is intended for residential and light commercial environments where rapid detection and a wireless installation simplify placement and maintenance.
Advantages
The photoelectric sensing method provides reliable detection of slow-burning and smouldering fires while reducing false alarms from cooking fumes compared with ionisation sensors. Wireless connectivity enables flexible installation without the need for new cabling and allows the detector to integrate into supported alarm systems. Battery operation ensures continued function during power outages, and the integrated sounder delivers immediate local notification to occupants.
Suitable for
 Homes and apartments
 Small offices and retail spaces
 Storage rooms and garages
 Areas where wired installation is impractical
Key specifications
 Detection method: photoelectric (optical) smoke sensing
 Power supply: battery-powered for wireless operation
 Alarm output: local audible alarm
 Wireless communication: compatible with supported alarm control systems
 Intended use: indoor smoke detection for residential and light commercial spaces
How to use
Install the detector on a ceiling or high on a wall in accordance with local codes and the alarm system manufacturer’s installation guide. Ensure the unit is within range of the alarm control panel for reliable wireless communication. Remove the battery tab or insert the battery as specified, test the detector using its test function after installation, and verify the audible alarm and wireless signalling to the control panel. Replace batteries according to the manufacturer’s recommended intervals or when low-battery indication is received.
Usage recommendations
Place detectors in sleeping areas, living rooms, hallways serving bedrooms, and on each storey of a building. Avoid installing directly next to cooking appliances or in very dusty or humid locations that may affect sensor performance. Perform regular testing and scheduled battery replacement to maintain continuous protection.
