2 doors wireless relay and keypads


This job was to install 2 door phones, a wireless relay for the doors, and keypads for 2 doors. The wires for the doors and the latches were already in place when work began. This took about 4 hours to complete. The hardware is mounted to the wall behind the network rack.

GREEN + ORANGE = POWER
BLUE + PURPLE = DIAL TONE
GRAY = N.O.
BLACK = COMMON (POWER)
RED = POWER TO LATCH
This image shows all devices getting power from one power supply,
and the release getting power from a second power supply.
If your power supply is weaker (lower mA rating) you may need a power supply for each relay.
If your power supply is stronger, you may be able to share power for the release and latch.
