WIRING VOLTAGE OUTPUTS<br />
The Lock output (LK) and Chime Voltage output (CH) will provide 12 Volt DC @ 50mA<br />
which can be used to power up relays which in turn will switch voltage to the device being<br />
used.<br />
WARNING<br />
Using these outputs to drive a load, with a resistance of less than 240 ohm, will damage<br />
the output transistors.<br />
Check coil resistance of relays to be used with a multimeter.<br />

The LK terminal provides an output voltage (to activate an automatic gate or release a<br />
door strike) whenever an “8” button is pressed at the Master or any Room Station.<br />
To use this output, no additional wiring is required between the Master, Room Stations and<br />
the Door Station, except for the cable required to deliver power from the power source, via<br />
the lock relay contacts, to the lock - see section "<strong>Installation</strong> of VF103 Door Stations - Lock<br />
Output".<br />
If this feature is to be used, number “8” should be avoided when programming Room<br />
Stations for private dialling.<br />
