Smoke detector KIDDE 10Y29 with optical sensor, battery-operated, sealed 10-year life

KIDDE 10Y29 is a battery-operated smoke detector with an optical (photoelectric) sensor and a sealed 10-year battery/service life. Designed to detect slow-smouldering and visible-particle smoke, it provides audible alarm alerts suitable for residential and small commercial spaces. The unit is compact, intended for surface mounting on ceilings or high on walls, and requires minimal maintenance because its battery and sensing components are sealed for the specified service life.

Advantages

The optical sensor offers reliable detection of smouldering fires and visible-particle smoke while reducing false alarms from cooking or steam compared with ionisation-only devices. A sealed 10-year battery and service life eliminate the need for regular battery replacements and reduce maintenance interventions. The detector emits a clear audible alarm to alert occupants and has a compact form factor that supports straightforward surface installation. Low-maintenance design and long-life operation make it practical for bedrooms, hallways and living areas.

Suitable for

• Homes: bedrooms, living rooms and hallways
• Small offices and commercial premises
• Rental properties and managed residences where long-life, low-maintenance detectors are preferred

Key specifications

• Detection principle: optical (photoelectric) sensor for visible-particle smoke
• Power source: sealed long-life internal battery with up to 10 years service life
• Alarm output: audible alarm suitable for alerting occupants
• Mounting: surface mount for ceiling or high wall installation
• Intended application: residential and small commercial spaces

How to use

Install the detector on a ceiling or high on a wall following the included mounting template and hardware. Avoid placing the unit too close to cooking appliances or bathrooms to minimise nuisance alarms from normal cooking fumes or steam. Test the alarm after installation using the detector's test function to confirm audible operation. Because the battery and sensor are sealed for the 10-year service life, routine maintenance is limited to occasional surface cleaning of dust with a soft brush or vacuum attachment and periodic testing per local safety recommendations.

Usage recommendations

Position the detector in bedrooms and on each level of the dwelling for comprehensive coverage; follow local building codes and manufacturers' placement guidance. Replace the detector at the end of its 10-year service life to ensure continued reliability.
