This doorphone/door opener card is composed of the control interface with KX-TES824/KX-TEM824 and four doorphone interfaces
and four dooropener interfaces section.
Doorphone section:

1. This card has four doorphone interfaces, but this system has only two door phone intercom paths.

Therefore, this card has a programmable SW to connect either DOORPHONE1 or DOORPHONE2.
For example: When the DOORPHONE1 is used, the DOORPHONE2 hears a busy tone. This is repeated for Doorphone 3
and 4.
This doorphone intercom path is composed of the send amplifier and receive amplifier circuits.
The interfaces have the doorphone connect detection circuit and the doorphone hook detection circuit.

2. This doorphone/dooropener card has four dooropener interfaces. These interfaces are used for the dooropener SW (DC 30/

AC 250 5A)

Supports the connection of 4 doorphones and 4 dooropeners.
1. Loosen the screws and open the top and bottom front covers.
2. Attach the 4-Port Doorphone Card to the main unit, connect the cord to the Doorphone Card Connector and secure the screw.

Use extra care to make sure you do not damage the part of the case marked with a circle.

3.Close the covers and secure the screws.
