212iLM Keypad Installation & Programming
Wiring the Bell Output to a Speaker:
The 212iLM keypad has a built in bell button, which triggers a relay output when pressed. This relay is normally open and
the contact closes when triggered. You can use this relay output to trigger devices that require a momentary closure, such
as a doorbell. The relay output provides a dry contact, but you can run up to 30 volts AC/DC through it for devices that
require power to operate. The diagram below shows these connections.
