SYSTEM OPERATION

To make a call the visitor should press the push button corresponding to the apartment he wishes to contact. An acoustic tone will be heard confirming the call is in progress once the push button has been pressed. At this moment the call will be received at the monitor (telephone) in the dwelling. During the call the visitor can correct his call by pressing a push button corresponding to a different apartment, in which case the original call is cancelled.

In systems with several access doors, the other(s) door panel(s) will be automatically disconnected: if a visitor tries to call from other door panel an acoustic tone will be heard confirming the system is busy.

The call tone will be reproduced on the monitor during 3 seconds: after this time the picture will appear on the master monitor without the visitor being aware of this. To see the picture in a slave monitor press the push button, dissapearing the picture on the other monitor. If the call is not answered in 45 seconds, the system will be freed.

To establish communication pick up the monitor (telephone) handset. The communication will last for one and a half minutes or until the handset is replaced. Once the communication has finished the system will be freed.

To open the door, press the door release push button during call or communication progresses: with one press, the door release operates during 3 seconds. During the lock release activation an acoustic tone will be heard on the door panel confirming the lock release is activated.

The monitor and telephone push buttons description is shown on pages 66 and 71 respectively.

Troubleshooting and error codes

TROUBLESHOOTING HINTS

Nothing operates.

  • Check the output power supply voltage between '-' and '+' terminals: it should have 17,5 to 18,5Vd.c. If not, disconnect the power supply from the installation and measure again. If it's correct now, it means there is a short circuit in the installation: disconnect the power supply from mains and check the installation.
  • Check that 'D' terminal is not shortcircuited with '-' or '+' terminals.
  • Check that 'D' terminal hasn't been changed by 'A' terminal somewhere in the installation.
  • If these tests don't solve the problem, check the voltage between 'B' and 'CP' terminals of the EL500 circuit; if the measured voltage is different to 12Vd.c. change the EL500 circuit.

Inappropriate audio level.

  • Adjust the level volumes as shown on page 63. In case of feedback, reduce the audio levels until feedback fade out. If feedback don't dissapears refer to the following hint.

Continuous audio feedback.

  • Check that 'A' terminal is not shortcircuited with other terminals.

Door open function no operates.

  • Remember that this function is only available during call and communication progresses.
  • Disconnect the lock release from the EL500 circuit and short-circuit terminals '-' and 'CV-': at that moment the output voltage between terminals 'CV+' y 'CV-' should be 12Vd.c. If it's so check the lock release and its wiring.

The system cannot be programmed.

  • Check that the switch number 2 of the configuration dip switch is set to ON (see page 62) and that the programming steps are correctly followed.
  • Check that 'D' terminal is not shortcircuited with other terminals.

Some units don't receive calls.

  • Remember that each apartment must have a master unit only. Check that the units are switched on and correctly programmed.
