Powering Locks with Seperate PWR
This example will illustrate how to power your locks with a separate Power Supply.
Since your locks share the same ground as your Access Control board you have to Bond the
two Power Supplies together. You would simply connect the
12vDC
output from your separate
power supply to each
COM
port for each lock. Below is an example 2 Metal Power Supply
Boxes. The chassis themselves are grounded so connect a 14 gauge wire to both chassis to
bond them together. This will allow them to share the same Ground to complete the circuit.
For ABS housings, you cannot bond the two Chassis together so instead you will have to connect them differently.
You will have to run a 14 gauge wire from the Ground output on the separate Power Supply to one of the ground
ports in the Main Power Supply. As for the 12vDC you will copy the same set up as before.
