The Kidde KF20 / 4973 is a 230V Optical Smoke Detector with Alkaline Battery Back Up from the Kidde Firex range.
The mains-powered detectors are inter-connectable, making them suitable for residential and light commercial environments.
In addition, the new KF20 also comes complete with a dust compensation and bug screen reducing the inconvenience of nuisance alarms.
The hard-wired units come with an alkaline battery backup and can be interconnected with other units from the series to create all-around fire protection within the home, when one alarm senses a fire, all units will sound.
The difference between the KF10 (Ionisation) and the KF20 (Optical) is that the ionization smoke alarm detects the smoke in the immediate atmosphere through the chemicals produced by the fire and the optical alarm "see's" the smoke within the atmosphere, both triggering the fire alarm warning.
