The Potter SignaLink Bridge is a fully supervised wireless bridge designed to be attached to any non-explosion-proof dry contact sprinkler monitoring devices. It removes the need to hard wire sprinkler devices to each other, and operates on a 2.4 GHz frequency. Devices are able to communicate with each other up to a maximum of 800’. All enclosures are weather and UV resistant polycarbonate. There are no external antennas. The antenna is incorporated into the circuit board of each device.
