The Crowcon Detective is a wireless portable gas detector, which uses the proven RICOCHET mesh network. When a network is established, the Detective Wireless automatically selects the best line to give the strongest interconnections. Should a wireless connection between two devices weaken, the network will “self-heal” and automatically re-reoute communications via alternate RICOCHET enables devices, creating a mesh type network which provides a more robust and efficient wireless network.
When the Crowwcon Detective+ goes into alarm, the signal will be sent to other units which alerts the user to has 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.
