The Hoyles Secure-a-Link system consists of two identical transceiver units, which are paired together, each requiring a local 12VDC power supply (max 250mA each). The units can transmit up to 60m in free space. The system is designed to take a clean contact input and transmit this wirelessly to another point, giving a clean contact output, without the need for hardwiring between the two points. Two way communication between the units is provided so that signals can be sent in either or both directions and once paired, the units only communicate within their pair, so multiple pairs of units can be used within the same area without interference.
