The Crestron® HZA-KEY1, HZA-KEY2, and HZA-KEY4 are keystone wallplates that match the aesthetic of Crestron Horizon™ keypads, dimmers,
and switches. The keystone wallplates are available with 1, 2, or 4 openings to accommodate a variety of keystone modules and to match the
installation requirement.
The HZA-KEY1, HZA-KEY2, and HZA-KEY4 are functionally identical. For simplicity within this guide, the term “HZA-KEY” is used except
where indicated.

Step 1 Step 2 Step 3
Install the HZA-KEY
The HZA-KEY utilizes integrated mounting screws to secure it to the electrical box. The HZA-KEY must be paired with an HZ-FP faceplate (sold
separately) to complete the installation.
CAUTION: Do not mix high- and low-voltage devices in the same electrical box without an approved barrier.
NOTE: If the HZ-FP is not available at the time of installation, fold the wires into the electrical box and then secure the HZA-KEY to the electrical
box using the integrated mounting screws. When the faceplate is available for installation, refer to the HZ-FP Quick Start (Doc. 8286) at
www.crestron.com/manuals.
1. Turn the system power OFF.
NOTE: For multi-gang installations, insert an alignment spacer (supplied with HZ-FP) between adjacent devices to maintain proper alignment
and spacing.
2. Place the metal mounting bracket (supplied with HZ-FP) over the back of the HZA-KEY. The two-part metal bracket clips together which
allows the wiring to remain in place.
3. Fold the wires into the electrical box.
4. Secure the HZA-KEY to the electrical box using the integrated mounting screws on the device. To allow for adjustments, do not fully tighten
the screws at this time.
5. Attach an HZ-FP to the HZA-KEY using the 4-40 x 1/4 in. faceplate mounting screws that are provided with the HZ-FP.
6. Ensure that the HZA-KEY is properly aligned within the HZ-FP and then fully tighten the integrated mounting screws to secure the HZA-KEY
to the electrical box.
7. Attach the magnetic top and bottom trim pieces (supplied with HZ-FP) to the HZ-FP.
8. Turn the system power ON.
