3MK Battery-Operated Photoelectric Smoke Detector

Ensure the safety of your home, office, or mobile space with the 3MK Battery-Operated Smoke Detector – a reliable and effective solution for early fire detection. Using advanced photoelectric sensing technology, this smoke alarm is especially sensitive to slow-burning, smoldering fires — the type commonly caused by unattended cigarettes, overheated wiring, or ignited upholstery.

Designed for ease of use and quick installation, the 3MK Smoke Detector operates independently on a 9V battery, providing continuous monitoring without the need for hardwired connections. Whether you're equipping a house, rental property, caravan, or small business, this standalone alarm adds an essential layer of protection.
