Smoke detector Plum SHS-10S with 10-year built-in battery, optical smoke sensor

Plum SAFEMI SHS-10S is a standalone smoke detector with an optical smoke sensor and a factory-installed sealed battery rated for up to 10 years of normal operation. The device is intended for continuous monitoring of indoor air in residential and small-business environments and provides an audible alarm and a low-battery indicator. Its compact, ceiling- or wall-mountable enclosure is designed for simple installation and unobtrusive presence in bedrooms, corridors, living rooms and other indoor spaces where early smoke detection is required.

Advantages

The optical sensor detects visible particles from smouldering fires and offers reliable response to common household fire signatures. The built-in long-life sealed battery eliminates the need for regular battery replacement for the rated service life, reducing maintenance. The detector includes an audible alarm and a low-battery signal to keep users informed of device status. Its design supports both ceiling and wall mounting and is suitable for typical indoor mounting heights.

How to use

Install the detector on a ceiling or high on a wall following local building codes and the manufacturer’s mounting guidance. For optimal detection, place units away from air vents, ceiling fans and locations with frequent steam or cooking smoke; avoid mounting directly above cooking appliances. After installation, perform a brief functional check using the device test function to verify the audible alarm and status indicator. Monitor the low-battery signal during the device life; when the end-of-life or low-battery indication is displayed, replace the detector according to the manufacturer’s instructions.

Usage recommendations

Place a smoke detector in each sleeping area and on each level of a home or small office to provide overlapping coverage. Test the unit regularly, keep the sensing chamber free of dust and paint, and avoid installing in areas with continuous high humidity or heavy airborne particulates to maintain reliable performance.
