Yale YRM 20 AMC Video Door Phone Transmitter Module

Overview

The Yale YRM 20 AMC lets you unlock a Yale digital door lock from your indoor video door phone, so whoever answers the call can let a visitor in without walking to the door. It is a transmitter that connects to the video door phone and sends a wireless unlock signal to the lock, which must have the Yale YRM 20N receiver module fitted inside it. It is one half of a pair and does not work on its own.

Is it right for you?

• Choose it if your lock is a YDM4109 A, YDM4109A RL, YDM 4115 A, YDM 3115 A, YDR 41 A or YDD 724 A and you want door release from the door phone.
• It works with video door phones of any brand, as long as a 12 V DC supply is available at the door phone to power it.
• If you only want a handheld remote and have no video door phone, the Yale RC 100 remote with the YRM 20N is the simpler pairing.

Key features

• Wireless link to the YRM 20N receiver inside the lock, so no cable runs from the door phone to the lock.
• Sits at the video door phone indoor unit and runs on 12 V DC there.
• Not tied to one door phone brand.

What else you need

• The Yale YRM 20N receiver module fitted in the lock. This is always required; order both together.
• A video door phone with a 12 V DC supply at the indoor unit to power the transmitter.
• A supported Yale lock from the list above.

Installation

The transmitter is wired to the video door phone’s door release output and to a 12 V DC supply, then paired with the YRM 20N in the lock. A qualified installer should do the wiring and confirm how the module will be powered at your door phone, as door phone models differ in their release outputs.

Before you buy

• Order the YRM 20N receiver module as well; the YRM 20 AMC does not work on its own.
• Check that your lock is one of the models listed above.
• There is no published list of tested video door phone brands, so ask your installer to confirm the wiring and power at your door phone before ordering.
