The CAVIUS Wireless alarms interconnect to each other using innovative Radio Frequency technology; when one alarm activates, they all sound.
The 10-year lithium battery-operated CAVIUS Wireless alarms require no wiring. Setting up and interconnecting the alarms is a simple 2-minute process. Once connected when one alarm starts to siren, it will send out a 360-degree signal to all other CAVIUS alarms in range.
