Radio-Interlinked Battery Powered Optical Smoke Alarm - Ei3105RF

Yes, the Ei3103 range, Ei3100RF - Ionisation Smoke Alarm Ei3105RF - Optical Smoke Alarm Ei3103RFU - Heat Alarm, interconnect with each other. If one sounds it will send a radio-signal to the other units and they will then be activated.

The Ei3100RF series of battery operated smoke alarms are complete alarms, they do not require base plates to make them radio interlinked.

There are three different alarms that make up the Ei3100 series. The Ei3100 optical alarm does have a hush button, which can be pressed to reset the alarm should a false alarm occur. The ionisation and heat alarms do not have hush buttons. Should either of these alarms trigger a false alarm, due to cooking fumes for example, the alarm can be silenced using a folded newspaper to fan underneath it. To identify which alarm has triggered the false alarm it is the unit with a rapidly flashing red LED.

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.

Yes that is correct, the radio frequency technology in these alarms allows them to be connected wirelessly. This is acheived by following the step by step house coding procedure in the instructions, the procedure ensures that all alarms in the series are 'tuned in' to each other allowing them to pass messages on. If a fire was to occur in your roof space the alarm located up there would sound and send a message to the alarm downstairs which would then sound to alert anybody in the premises.
