Standalone Optical Smoke Detector

The Standalone Optical Smoke Detector provides immediate fire warning for homes, apartments, small offices, and rental units across Kenya. This battery-operated detector requires no wiring or central fire alarm panel — simply mount it on the ceiling, insert the included 9V battery, and your space is protected.

The detector uses photoelectric (optical) sensing technology, which is highly effective at detecting slow-smouldering fires that produce visible smoke particles — the most common type of fire in residential settings. When smoke enters the detection chamber and scatters the infrared light beam, the built-in 85 dB sounder activates, giving occupants precious time to evacuate.

A test button allows weekly functional testing as recommended by fire safety guidelines. The low-battery chirp alerts you approximately 30 days before the battery is fully depleted, ensuring continuous protection. The detector automatically resets once smoke clears, and a red LED flashes every 40 seconds to confirm the unit is operational.

The compact circular housing (100 mm diameter) mounts flush to any ceiling using the included screws and twist-lock base. The white finish blends with most Kenyan residential and office ceiling finishes. The detector is suitable for bedrooms, living rooms, hallways, and stairwells.

Lance Security encourages every Kenyan household to install at least one smoke detector — an investment of just KES 1,200 that could save lives. We stock these detectors in quantity for property managers, landlords, and Airbnb hosts who need to equip multiple units. Bulk discounts available on orders of 20 or more.
