Smoke Detector Eura SD-87A2 – mains/backup power, optical sensing

Eura SD-87A2 is a ceiling-mounted smoke detector that uses optical (photoelectric) sensing to detect smoke particles from smouldering fires at an early stage. The unit is designed for continuous monitoring of indoor air in homes and commercial spaces, and it operates from mains power with an integrated backup battery to maintain functionality during power interruptions. The detector supports standard alarm signaling to alert occupants and can be installed in hallways, living rooms, bedrooms and small offices where early smoke detection is required.

Advantages

The optical sensor provides reliable detection of slow, smouldering fires while reducing false alarms from normal cooking fumes and steam. Mains operation with a backup battery ensures the detector remains active during power outages, and the ceiling mounting saves space and provides optimal coverage for smoke rising toward the ceiling. The detector is compatible with typical domestic and light-commercial installations and is designed for straightforward wiring and maintenance.

Suitable for

• Residential hallways and living areas
• Bedrooms and common rooms in homes and apartments
• Small office spaces and meeting rooms
• Corridors and communal indoor areas in light-commercial buildings

Key specifications

• Detection principle: optical (photoelectric) sensing
• Mounting: ceiling-mounted design for optimal smoke detection
• Power supply: mains power with built-in backup battery for uninterrupted operation
• Alarm output: local audible alarm for occupant notification
• Environment: intended for indoor use in residential and light-commercial spaces

How to use

Install the detector on the ceiling in a central position of the protected area, avoiding corners, direct airflow from vents and locations too close to cooking appliances to reduce false alarms. Connect the unit to the mains supply following local electrical regulations and ensure the backup battery is correctly inserted and charged. Test the detector after installation using the built-in test function and perform periodic tests according to local safety guidance to confirm proper operation.

Usage recommendations

For reliable smoke detection, place the detector on the ceiling at least 30–50 cm away from walls and avoid installing it directly above kitchens or bathrooms where normal cooking or steam may cause nuisance alarms. Replace the backup battery and test the device regularly; if the detector indicates a fault or end-of-life condition, replace the unit according to the manufacturer’s maintenance instructions.
