Verkada intercoms include an output relay that you can use to trigger a doorbell or chime.
You need a third-party power supply to power an intercom.
This guide applies to 4 wire chimes. If you have a more traditional doorbell setup like the diagram below, see Traditional Doorbell Wiring for Verkada Intercoms for a detailed wiring guide.
Configure a chime output
In Verkada Command, go to All Products > Intercom
.Select your intercom and click Settings.
Under I/O > Output, select Chime.
Wire your intercom
4-wire bells have 2 wires dedicated to power and 2 wires dedicated to triggering the bell sound. This procedure applies to a single doorbell (or multiple doorbells) wired in parallel, as shown in the image.
Remove the terminal block or pigtail from the rear of your intercom.
For each doorbell, wire bell+ and bell– to the NO and COM outputs on the intercom terminal block/pigtail, respectively.
For each doorbell, wire positive voltage and ground to the positive voltage output and ground on your power supply, respectively.
Reinsert the terminal block into the intercom.
If you have multiple doorbells, wire them in parallel.
