## Long description

The DELTA-OPTI SDA-250 is an autonomous optical (photoelectric) smoke sensor designed for standalone fire detection in homes, offices and small commercial premises. The detector continuously monitors for visible combustion particles and triggers a local audible alarm when smoke is detected. The self-contained design requires no external control panel or wiring for basic operation, making it suitable for applications where independent smoke detection is required.
Advantages
The optical sensing chamber provides reliable detection of smouldering fires and visible particle build-up while reducing false alarms from brief non-hazardous aerosols. Built as a self-contained unit, the detector is simple to install and maintain, with a compact profile that blends into typical interior ceilings or walls. The audible alarm alerts occupants locally, offering immediate notification without the need for external systems.
Suitable for
Residential rooms and apartments
Small offices and administrative areas
Retail premises and small commercial spaces
Storage rooms, corridors and utility areas

How to use
Install the detector on a ceiling or high on a wall according to room layout and manufacturer spacing guidelines. Power the unit as specified by the manufacturer and verify the detector’s ready/standby indication. Test the alarm function after installation to ensure audible notification is operating. Clean the sensing chamber periodically following the manufacturer’s maintenance instructions to maintain sensitivity and reduce false alarms. Replace consumable power sources or the device according to the manufacturer’s recommended service life.
