10 Year Longlife Battery Radio-Interlinked Heat Alarm - EI603TYCRF

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.

The Ei600 series of radio-interlinked alarms are completely battery operated. This means that they do not need to be wired up to the mains circuit. On the website, we offer the Ei600 series with a standard 9v battery or with a 10 year lithium longlife battery. The standard 9V batteries last approximately 12-18 months depending on how often the detectors are tested. The lithium battery units are sealed and last 10 years i.e. the full lifespan of the detector.

If one alarm was to malfunction the other units would not be affected, if it was due to alarm failure. If the fault was with the radio-interlinking signal, then all alarms that are in the chain after the faulty alarm would be affected and they would not go off.
