## Long description

The Kidde KID-29HD Optical Wireless smoke detector is a compact, battery-powered unit designed to detect smoke quickly and provide audible alerts in domestic environments. With optical sensing technology housed in a low-profile enclosure, this detector responds to smouldering and smoldering-type fires while fitting unobtrusively on ceilings or walls. Its lightweight construction and simple installation make it suitable for single-room protection and for use as part of a wireless alarm network where compatible devices are present.
Advantages
The optical sensor provides reliable detection of slow, smoldering fires that produce large amounts of smoke before open flames develop. As a wireless, battery-operated unit it requires no mains connection, allowing flexible placement and quick installation. The compact size and low weight reduce visual impact in living spaces, and the audible alarm offers clear notification of danger. Designed by a recognized manufacturer in home safety products, the detector meets typical functional expectations for residential smoke detection.
Suitable for
 Bedrooms and living rooms where early detection of smoldering fires is important
 Hallways and stairwells to provide audible warning routes
 Homes or flats without convenient mains power access for detectors
 Supplementing existing wired systems with wireless coverage
Key specifications
 Sensor type: optical (photoelectric) smoke detection
 Power supply: single 9V battery
 Dimensions: approximately 100 mm diameter, 38 mm depth
 Weight: approximately 102 g
 Alarm output: audible alarm suitable for domestic warning

How to use
Install the detector on a ceiling or high on a wall following the manufacturer’s mounting instructions and ensuring the unit is oriented according to the printed guide. Fit a 9V battery before initial use and test the unit using the test button to confirm audible operation. Place detectors in each sleeping area and on every level of the home for comprehensive coverage. If used in a wireless configuration, pair the unit with other compatible devices according to the pairing procedure provided by the system to enable interconnected alarms.
Usage recommendations
Test the detector weekly and replace the 9V battery at intervals recommended by the manufacturer or immediately after low-battery warnings. Avoid installing the detector near kitchens or bathrooms where normal cooking fumes or steam may cause false alarms; instead, place detectors at least one metre from cooking appliances and away from direct airflow from vents. Clean the detector exterior periodically with a soft brush or vacuum attachment to remove dust; do not use solvents or immerse the unit. Replace the detector according to the manufacturer’s end-of-life guidance to maintain reliable smoke detection.
