The Key reader is connected to the Relay card KEY READER connectors, whereupon a green light in the Key reader indicates when the device is powered up (ONLINE LED). The red or green key symbol indicates whether the key, inserted into the Key reader, was approved or rejected (STAT1 G and STAT1 R).

The Key reader also has inputs STAT2 GRN, STAT2 RED and GND for status indications of the device under control. You can bring feedback information these inputs from the device under control in the form of 3.3 – 24 VDC. If no feedback information is received from the device under control, the Relay card can also be connected to control the STAT2 GRN LED. In such cases, the STAT2 output will follow the Relay card relay output K1 status (except when in the Roller door mode).

In cabling, use a data transfer cable, such as MHS 5x2x0.5, should be used. The maximum distance between the Relay card and the Key reader is 100 metres.
