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. |
