Wireless smoke alarms communicate via radio frequency.

Wireless smoke alarms have a signal unique to the model that will wirelessly connect with others in the same model series.

For the alarms RF-SM-ACDC and RF-SM-DC, we have our own frequency band of 434.3. Each wireless alarm has dip switches on the back of the unit. When all switches are on the same setting, all smoke alarms will sound when the Test/Reset button is pushed.
