ULTRA-FIRE  UBS 1RF Smoke Alarm and Radio-Interlink.

Hello there, I wonder if you could help me please?   For health reasons, we don't have Wi-Fi, cordless telephones etc. in our house, so I would like to know a bit more about the Radio-Interlink.  Under normal 'standby' conditions, does it transmit continuously 24/7, which obviously wouldn't be suitable for our purposes, OR does it only transmit under certain circumstances i.e. for the few seconds when additional alarms are being programmed in, also when the test button is pressed, when a low batt alarm is given etc, and of course when there is an actual alarm, which of course would be acceptable for us?

There is the old fashioned method of interlinking via cable using standard interlink smoke alarms. I doubt they transmit continuously as the batteries wouldn't last too long but the manufacturer will know the full info - if it's any use to you they transmit on 868MHz

Thanks
