The wireless module provides the Voltex 240V smoke alarm SAS135MH with wireless interconnectivity by simply plugging into SAS135MH.
It can connect up to 40 units of SAS135MH and /or the battery version smoke alarm SAS115BW.
Thanks to new digital technology the signal has been digitally modulated and won't interfere with other devices.
Pairing is extremely simple - once a 'master' alarm is set up, the Test button on each device is pressed three times. Done!
