| UNIT 3: INSTALLATION - LESSSON 5: OPTIONAL ACCESSORIES Doorphone and Door Opener Connection When an optional KX-TAW84861 Doorphone and Door Opener card is installed, the system will have the capability of connecting up to 4 doorphones and 4 door-opening devices. The Doorphone model KX-T30865-W (white) or KX-T30865-B (black) can be located at doors, gates, or any other location where the user wishes to have two-way communication, but does not require a telephone. The KX-T30865 doorphone is designed to be surface mounted. Wiring from the location of the doorphone, back to the MDF will be the same style and type that was used for the telephones. The only difference is that each doorphone only requires one pair of wires. Usually a separate cable run is made for each doorphone. Be sure to label each cable with the appropriate doorphone number. Once the wiring is in place, the connections to the doorphones and the Doorphone/Door Opener card can be made. Additional jack(s) need to be installed on the backboard near the MDF. If one or two doorphones will be installed, one surface mounted 4-wire modular jack needs to be attached. If a third or fourth doorphone will be installed, a second modular jack will be needed. These jacks will be used to terminate the cables at the MDF, and then make the connection to the Main Unit. Terminate the doorphone cables onto the jack(s) at the MDF by connecting the pair of wires for doorphone 1 to the red and green terminals and the pair of wires for doorphone 2 to the yellow and black terminals. Once the cables are terminated on both ends, the connection to the DPH4 card must be made. Connect a 4-wire modular line cord between the doorphone jack on the MDF and the top modular port on the DPH4 card. If a third or fourth doorphone is to be installed, follow the same procedure by terminating cables 3 and 4 on a modular jack for doorphones 3 and 4. Then run the modular cord from this modular jack to the lower port on the DPH4 card. Another option that is offered by the Doorphone/Door Opener card is the ability for the user to activate door-opening devices. Often called electric door strikes, these units are installed into doorframes and allow the users to open a locked door by dialing a feature code on the telephone. Follow the manufacturers’ instructions for the installation, power supply requirements, and wiring of these devices. Most manufacturers of these devices include installation instructions on how to interface with a telephone system or PBX. It most often includes wiring a low-voltage switch in series with the door strike and power supply. The Doorphone/Door Opener card provides that switching requirement. Remember, the Doorphone/Door Opener card does not provide any power to the door strike unit. Power must be provided by an external power source. On the DPH4 card, you will notice 2 connectors. The top connector closest to the modular doorphone ports is the door opener connector that provides the relay contacts used to activate the door strike or opener. Insert the provided 10-pin terminal block into the DPH4 card. Insert the wire from the door opener into the holes of the connector in accordance with the terminal block diagram on page 60 of the Installation Manual. Then wire the relay contacts in series with the door strike wiring according to the manufacturers’ instructions. Note: The current limit for the door opener contacts is: 24 V DC/30 V AC, 1 A maximum
