Power Supply
This unit is designed to be a fixed installation, operated from either 12/24Vdc or 230Vac. Under no
circumstances should the receiver be connected to more than one supply. Before removing the cover
ensure that the mains input supply is isolated. Maintenance to the product that involves removal of the
cover should only be carried out by a competent person or qualified electrician.
Data Outputs
Each output relay provides an isolated switch. Connections are Common (COM), Normally Open (NO) and
Normally Closed (NC).
Connecting a Relay output to an Application
Below is a simple example showing one possible way to wire a relay in order to give switched power to an
external load:
When the relay is energised the ‘COM’ connects to
’NO’ and power is applied to the Load.
Pairing a Transmitter to a Receiver
Each transmitter has a unique identity. Each time a switch is pressed, the transmitter emits a highly secure RF
signal (appears as a random encrypted data stream). The Receiver can learn this encrypted signal and
allocate to an output.
Any transmitter switch may be paired to one or many of the receiver’s outputs, or a transmitter single switch
may be paired to any number of receiver’s outputs to enable a powerful and flexible remote control system.
The only limitation is that each receiver has a maximum capacity of 15 pairings, these can be from the same
or any number of transmitters.
Hint: the same transmitter may be taught to any number of receivers to create ‘master keys’.
