Wiring the CH Output<br />
The Chime Voltage Output terminal (CH) will provide 12 Volt DC @ 50mA which can be<br />
used to power up a relay, which in turn will switch voltage to the device being used.<br />
WARNING<br />
Using this output to drive a load with a resistance of less than 240 ohm will damage the<br />
output transistor.<br />
Check relay coil resistance with a multimeter.<br />

V+ and V- can be taken from POS and NEG<br />
of the door station for low current applications<br />
(500mA or less).<br />
A separate power source is recommended for<br />
higher current applications.<br />
