Secure-a-Link Wireless relay transmitter / receiver system

The Secure-a-Link system consists of two identical transceiver units, which are paired together, each requiring a local 12Vdc power supply (max 150mA each). The wireless relay units will transmit up to a maximum 125m range with clear line of sight and tested up to 25m indoors.

Please Note: For best results mount away from metal objects. The range and performance of any wireless product depends on the structure and environment in which it operates.

The system is designed to take a volt free input and transmit this wirelessly to a second point, giving a relay 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.

Each of the units has two-volt free inputs that trigger two relay outputs on the unit it is paired with. Each unit also has a NC tamper output with goes open when either unit is in tamper.

The inputs can be configured to normally open or normally closed. The outputs can either latch, following the state of the input, or commutate, switching every time there is a momentary input.
