The Verkada BR31 wireless door sensor can be used as a universal transmitter, enabling wired alarm devices to communicate wirelessly with Verkada wireless hubs.
Collect the required components, including the main body of the BR31, a T10 Torx screwdriver, and the wired sensor.
Use the T10 Torx screwdriver to unscrew the Torx screw on the underside of the BR31. Remove the backplate of the unit.
Plug the leads of the wired alarm sensor into the 2 inputs at the top of the BR31 unit. Polarity does not matter in this case.
Command set up
Add the device to Command before you continue.
Navigate to the Devices page in the alarm site.
a. At the top right, click the ellipsis icon. b. Click Edit Sensor.
In the device settings:
a. Enable Universal Transmitter Mode. b. Select the normal state of the sensor (see specific, relevant sensor). Wired door contact sensors are commonly "Normally Closed". c. Click Done and wait a few minutes for the new configuration to update on the BR31.
Manually trigger the wired sensor to confirm that the BR31 is transmitting the sensor events to Command.
Once device performance is confirmed, follow the mounting steps in the BR31 Install Guide to complete the installation.
