Mounting 1/3

Using the provided T10 Torx Wrench, loosen the security screw at the base of the Relay.

With the security screw fully loosened, lift the cover upwards to remove it entirely.

Wall Mounting: At the installation location, mark the mounting surface through the perforations in the top-right and bottom-left of the Relay, as shown.

For a solid material like wood or  metal, drill ⅛ inch pilot holes in the mounting surface at the marks. For drywall, drill ¼ inch holes. Insert plastic Wall Anchors into the holes. Secure the Relay to the surface using the provided Wall Screws.
VHB Mounting: Peel the protective film from one side of the adhesive mounting strip. Adhere to the back side of the Relay. Peel the remaining protective film and affix the Relay to the mounting surface.

Mounting 3/3
Wire the Relay.
See Pages 10-13 for Recommended Wiring Instructions.

Once wiring has been completed, replace the device’s cover.
Tighten the security screw.

Recommended Wiring (1/4)

Verkada’s BX21 Wireless Relay is capable of supporting output devices e.g. sirens, strobes, etc. that require 12-24V voltage and draw up to 2.5A for 12V or 1.25A for 24V
(resistive).

Wiring methods shall be in accordance with National Electrical Code, ANSI/NFPA 70.
Shielded Wiring
With the BX21, you must use shielded wiring. Improper shielding may result in unintended product behavior.
The BX21 Wireless Relay sits in-line with DC-powered output devices which can be triggered wirelessly. The Relay can also transmit signals from a wired input.
The Relay enables output devices in a wet configuration, i.e. devices which do not draw power from external sources beyond the Relay itself.
According to the requirements of the output device, these should be wired to either the Normally Open (NO) or Normally Closed (NC) terminals in the terminal block denoted Relay.
The power source which supplies the Relay, and implicitly the output device, should be wired to the terminal block marked Power.
Recommended Wiring (2/4)
Wiring Steps:

1. Noting polarity, wire the output device to NO (Page 12) or NC (Page 13) and COM on the Relay terminal 7block.
2. Optionally: wire an additional input to the Signal terminal block e.g. a door sensor.
3. Noting polarity, wire a 12-24VDC power source to GND and COM on the Power terminal block.
4. Press and hold the Test/Pairing button to trigger the Relay (the button is recessed and is easily accessed using the provided Torx Wrench).
   If wired correctly, the output device should exhibit its expected output behavior.
   Upon output device failure, please confirm the device operates within  power limitations and that the Relay iswired as per instructions.
   The Test/Pairing button can also be pressed in the event that the Relay does not automatically pair with a BH61 Hub, however, this behaviour is not expected.
