Detective Wireless

A wireless module that can replace interconnecting cable for Detective+



Detective Wireless uses the proven RICOCHET mesh network. When establishing a mesh network, Detective Wireless automatically selects the best line to give strongest interconnections. Should wireless connection between two devices weaken, the network will ‘self-heal’ and automatically re-route communications via alternate RICOCHET enabled devices, creating a mesh type network that provides a more robust and efficient wireless network.

When Detective+ goes into alarm, the signal will be sent to other units alerting the user to gas being present in the area. If the signal is weak due to heavy metal work being present the Detective Wireless can be used as a repeater to boost the signal between units. In a confined space the unit can use up to 20 metres of cable to position the unit in a location that will increase signal.
