10 Year Longlife Battery Radio-Interlinked Smoke Alarm - Aico Ei650RF

Most radio-interlinked alarms have a range of 150 meters in an open space and up to 30 meters in buildings. The thickness of the walls and partitions will affect the travel distance of the signal.

Ionisation smoke alarms detect fast flaming fires and are suitable for landings. Optical smoke alarms detect slow smouldering fires typical for burning soft furnishings. Optical alarms are suitable for living rooms and sleeping areas and are used near kitchens as they are less prone to false alarms. Please note that ionisation alarms contain a small amount of radioactivity.

The manufacturer's recommendation is to test the alarm by pressing the test button. This will simulate a heat input at the heat sensor. You can also test it with a hair dryer but make sure that the hairdryer is kept away at a suitable distance from the alarm. Do not attempt to test the alarm by using open fire or excessive heat as this may damage the unit.

Yes this entirely possible. The Ei140 series with RF base is mains powered and these are compatible to interlink with the battery operated Ei3100 series. Please view the interconnection overview on either of these alarms for further details.

Our radio-interlinked smoke detectors have a radio frequency range of about 30 meters in buildings. This means that as long as the detectors are all within 30 meters of each other, the interconnection should be achieved. Some of the RF smoke alarms can also act as repeaters, which means that larger distances can be achieved. So, a four storey house should normally be suitable for RF install.
