Installation

Follow these steps to proceed with installation.

1.

Align the center mark on the mounting plate and center on wall. Level and mark holes 1 and 2. Drill, anchor, and screw in place.

Note: Hole 2 is slotted for adjustments.

2.

Find the center of the 1.5 inch cable bore hole using marks as a guide. Temporarily remove the mounting plate and drill a 1.5 inch hole.

Drill and set anchors for remaining holes 3-6. Reinstall the mounting plate.

3.

Important: Keep the protective bumpers on.
Using the support cable, hook the Intercom to the mounting plate for easier wiring.

Align pocket in the bumper with the lower mounting plate tab. Place the loop of support cable over hook.

4a.

(A) Female RJ45

You may use an Ethernet cable to provide both power and internet to the device. Or you may utilize the direct power wires alongside onboard Wi-Fi or cellular.

(B) Male RJ45
(C) Connector Seal
(D) Split Gland
(E) Cable Seal

Step 1: Feed B through C and E
Step 2: Plug B into A
Step 3: Connect A to C by twisting. Add D behind C
Step 4: Screw E into C

4b.

If you’re not utilizing PoE, use crimps to connect to direct power.

Important: Ensure cables are dry and free of moisture before connecting.

5.

Unhook the support cable, remove bumpers, and feed all wires and cables through the wall. Use the center alignment pins to locate the product. Place the Latch Intercom flush with the mounting plate and slide down until all mounting tabs fit snugly.

Incorrect                      Correct

Note: We recommend forming a drip loop of cables to help avoid moisture condensation on connections or device.

6.

Lock into place with the TR20 security screw.

Important Handling Information

Operating Environment
Device performance may be affected if operated outside these ranges:

Operating and Storage Temperature: -22°F to 140°F (-30°C to 60°C)
Relative Humidity: 0% to 93% (non-condensing)

Cleaning
Although the device is water resistant, do not apply water or liquid directly to the device. Dampen a soft cloth to wipe the exterior of the device. Do not use solvents or abrasives that might damage or discolor the device.

Cleaning the screen: Although the device is water resistant, do not apply water or liquid directly to the screen. Dampen a clean, soft, microfiber cloth with water and then wipe the screen gently.

Cleaning the speaker mesh: To clean out debris from the speaker mesh perforations, use a can of compressed air held 3″ from the surface. For particles that are not removed by compressed air, painters tape can be used on the surface to pull out debris.

Water Resistance
Although the device is water resistant, do not apply water or liquid to the device, especially from a pressure washer or hose.

Magnetic Fields
The device may induce magnetic fields near the surface of the device strong enough to affect objects such as credit cards and storage media.
