SAFETY PRECAUTIONS
O Install or modify the equipment without the power connected.
O The installation and handling of these equipments must be performed by authorised personnel.
O The entire installation must be at least 40 cm. away from any other installation.
O With power supply:
wDo not use excessive force when tightening the connector screws.
wInstall the power supply in a dry and protected place without risk of drip or water projections.
wAvoid to place it near to heating sources, in dusty locations or smoky enviroments.
wDo not block ventilation holes of the unit so that air can circulate freely.
wTo avoid damage, the power supply has to be firmly fixed.
wTo avoid an electrical shock, neither remove the protection cover nor handle the connected wire in
the terminals.
Check the proper specified input voltage to "PRI" terminals of the transformer.
With telephones:
wDo not use excessive force when tightening the connector screws.
wInstall the telephones in a dry and protected place without risk of drip or water projections.
wAvoid to place it near to heating sources, in dusty locations or smoky enviroments.
wDo not block ventilation holes of the equipments so that air can circulate freely.
Before to connect the system, check the connections between door panel, telephones and transformer
connection.

DOOR PANEL DESCRIPTION

O
O
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 as the push button is pressed. At this
moment the call will be received at the telephone in the dwelling.
With several access doors, the other(s) door panel(s) will be automatically disconnected: if a visitor
tries to call from other panel an acoustic tone will be heard confirming the system is busy. If the
call is not answered in 30 seconds, the system will be freed.
To establish communication pick up the telephone handset. The communication will last for 3 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 at any moment during call and
communication progresses: with one press, the door release operates during 3 seconds.

Note: To realize the Serie 60 door panel replacement to Nexa 60, follow the steps described in the
manual 'Nexa 60 replacement' that it is supplied with door panel (aluminium modules).
Note: Replace the installation of several access Serie 60 '4+n' to Nexa 60 '4+n'. If telephones are not
compatible with electronic call they must be also replaced by Golmar electronic call-compatible
telephones. For the connection of the Nexa 60 '4+n', (see pages 55-56).
Important: If the installation transformer is replaced (A-100, A-104, A-105, A-120 and A-124) with
TF-104, the wire connected to terminal 3 must be annulled from replaced transformer.

OPTIONAL CONNECTIONS
TROUBLESHOOTING HINTS
O Nothing operates.
w Check the output transformer voltage between 'SEC' terminals: it should have 12 to 17Va.c. If not,
disconnect the transformer from the installation and measure again. If it's correct now, it means
there is a short circuit in the installation. Disconnect the transformer from mains and check the
installation.
O Inappropriate audio level.
w Adjust the level volumes as shown on page 50. In case of feedback, reduce the audio levels until
feedback fade out.
O Door open function no operates.
w Disconnect the lock release from the sound module EL651 and short-circuit terminals 'CV' and 'CV':
at that moment the output voltage between terminals 'CV' and '~2' should be 12Va.c. If it's so
check the lock release, its wiring and the wiring of the terminal 'P1' from the sound module to the
telephones. If these tests don't solve the problem, replace the sound module.
O No telephones receive the call or acknowledgement call signal is not reproduced.
w Check push buttons wiring (page 48) and the connection cable between modules are well connected in
the push buttons connector (page 49).
O Busy channel no operates.
w Check when a call is made on one of the door panels, the voltage between the terminals '-' and 'CO'
of all door panels is less than 3Vd.c. If not, check the continuity of the 'CO' wire.
w Remember: Door open function is only active during call and communication progresses.
