Art.280N1 Telephone Interface Unit
Description The 280 telephone interface allows a conventional telephone to be
connected to a Videx door entry system. The telephone can be either tone or pulse
dial. The unit also incorporates the facility to divert a door panel call to a pre-
programmed telephone number.
Important installation notes:-
1. A maximum of two telephones can be connected to the output of the
Art280.
2. Only one master socket should be connected to the output of the Art280.
3. Any other telecom equipment such as Sky, Red care, Faxes, modems
should be connected before the Art280.
4. When using the Art280N1 in divert mode the speech volume levels will be
lower than when used in normal mode. This is normal and is caused by a
10dB difference from the telephone exchange.
5. If the microphone volume at the door station is adjusted too high, it could
prevent the DTMF tones from being used to open the door or trigger any
of the other special features. The same problem could occur if there is
excessive back ground noise at the door station.
6. Telephone line or mains interference can cause problems for the
Artr280N1 to identify DTMF tones.
Connections to the telephone line Each telephone line coming into your home or
office must be fitted with a six pin primary socket installed by the PTO (Public
Telecommunication Operator). It is illegal to tamper in any way with this primary
socket and you can not install it yourself. Additional connections to the primary
socket must be carried out using a BT style plug (You cannot connect directly to the
terminals inside). The ART280 telephone interface unit is supplied with a BT style
plug. For more information, see relevant paper work supplied with extension sockets.
Using a conventional telephone it is possible to do the following :
• Make and receive outside calls. (Normal Ring)
• Receive calls from the door station. (Quick double ring)
• Open the door.
• Open the speech lines to the door.
• Place a call on hold while another call is answered.
• Activate an auxiliary output for 1 second [Aux1]. This is an open collector output.
(Can be used for a number of different aux. Equipment such as opening an
additional gate or door).
• Another open collector output [Aux] will activate throughout the conversation.
(Can be used to switch a camera on etc.)
• Divert a call to a pre-programmed telephone number.
• Dial into the art280 from a remote telephone.

Troubleshooting guide
In the event of problems occurring during the installation of the Art280 telephone interface please
check this troubleshooting guide before calling the Videx technical help on 0191 224 3174.
Telephone does not ring but if it is picked up during a call there is speech to the door :-
Option 1 : The REN value has been exceeded. Do the test again with only one telephone connected. If
it works then the REN value has been exceeded and the number of telephone on the system must be
reduced.
Option 2 : A master socket has not been fitted to the output of the ART280. The telephone will not
ring if this is a secondary socket or a faulty master socket. (The master socket has a large capacitor
inside.)
Option 3 : The correct voltage is not coming from the Art280. (An AC voltage of approx. 30 volts
should be present across T1 & T2 during the ringing cycle).
The speech lines do not open when * 7 is pressed :-
Option 1 : The Art280 has not been programmed to mode 4. To do this, pick up the handset and press
RECALL twice followed by 5 and then followed by 4. Hang up the telephone. The Art280 is now
programmed to mode 4.
Option 2 : The telephone you are using does not support DTMF dialing.
The door does not open when ‘0’ or ‘9’ is pressed :-
Option 1 : The Art280 has not been programmed to mode 4. To do this, pick up the handset and press
RECALL twice followed by 5 and then followed by 4. Hang up the telephone. The Art280 is now
programmed to mode 4.
Option 2 : The telephone you are using does not support DTMF dialing.
Option 3 : The lock is not wired correctly to the Art280. The Art280 has a dry contact relay output
across C & NO. These two terminals short together when the door open is activated.
The Art280 does not activate at all when called :-
Option 1 : Check the mains supply is connected to the Art280 and is correct.
Option 2 : Check the mains fuse inside the Art280.
Option 3 : Use a meter to check it is getting a signal across terminals 3 and 6 when a call is placed. The
voltage across these two terminals should be 12V AC or DC. (Without this voltage the Art280 will not
trigger).
There is no dial tone when the handset is lifted :-
Option 1 : Check there is a line tone before the Art280 by moving the telephone to the line input.
Option 2 : Check the line cord is connected to the incoming master socket and that the cord is not
faulty.
Option 3 : Check the new master socket fitted across terminals T1 & T2 of the Art280N has the wires
connected to terminals 2 and 5.
Option 4 : Check the telephone being used is working correctly.
Option 5 : Check jumper P is not fitted.
A telephone line is not being used. when a call is made the call can only be answered
during a ring :-
Option 1 : Jumper P has not been fitted. This must be fitted if a telephone line is not being used.
No speech from the door panel to the telephone :-
Option 1 : Check terminal 2 from the door panel to the Art280. When there are no calls on the system a
voltage of 8V DC should be present across 2 and negative.
Option 2 : If possible, test the door panel speech with a Videx telephone.
No speech from the telephone to the door panel :-
Option 1 : Check terminal 1 from the door panel to the Art280. When there are no calls on the system a
voltage of 8V DC should be present across 1 and negative.
Option 2 : If possible, test the door panel speech with a Videx telephone.
