PSM70 EVOLUTION BUTTON MODULE
GENERAL FEATURES
The PSM70 Evolution button module is characterised by an anodized grey aluminium structure and by blue LED diode backlit
name tags.
The module is ready to be used in B-Fast; 4+n ,1+n and 5 wire video systems. The diode plate is integrated in the lighting
system printed circuit.
The wiring procedures required for the modules consist in the following steps:
•
connection of two lighting wires;
•
connection to calling wires in the system, which must in turn be connected to the doorphones or video doorphones;
•
Diode Common (CD) to be connected in 1+n and 5-wire video systems only;
•
Button Common (CP) which must be connected to both upper/side terminals of each module, except for the case in
which connection is established automatically through the forks present on the lower part of the button.
If the PSM70 EVOLUTION button module is used in special applications, for example in EBUS or BFAST systems, follow the
instructions provided with these systems.
DESCRIPTION OF TERMINALS
The described terminals related to all button modules, from the 1-button, 1-2 user model to the 4 button, 4-8 user model.
L
Two terminals for connecting alternating current power wires, from terminals ~ and ~ of the 5-wire audio and video
units (12 Vac or 14 Vac)
CD
Diode Common present only in 1 and 2 button models (1-2 and 2-4 users). The wire from the CD terminal of the 5-
wire audio and video module must be connected to this terminal. (See system wiring diagrams for special
applications).
CD 1-4 Diode Common for 4 button models (4-8 users): the 2 upper buttons (the first 2-4 users in the button module)
CD 5-8 Diode Common for 4 button models (4-8 users): the 2 lower buttons (the last 2-4 users in the button module)
P1---P8 System calling wires. These must be connected to one of the following devices: to video doorphone terminal C, to
1+n doorphone terminal 2, to 4+n doorphone terminal C7.
Be careful to connect the P1-P8 terminals correctly when buttons are used in single user configuration.
BUTTON CONFIGURATION
The button modules are supplied with buttons in one-user, one card configuration. Pressing either the right button or the left
button will generate a call either to terminal P1 or to terminal P2. In this configuration, remember that only one user can be
connected to each button and that the calling wire must be connected to the ODD terminals (P1 P3 P5 P7).
Proceed with the following two steps to configure the button from one-user to two-user configuration:
•
For the electrical part, simply cut jumper(s) J1--J4 on the circuit and connect all the wires of buttons (P1,P2,P3…….) .
Electrical cutters may be used for this operation.
•
As concerns the mechanical part, the name tag housing must be transformed from a single housing to a double
housing. To do this, you will be need to change the name tag from the outside of the button. Use the specific tool
supplied to open the unit by levering in any one of the four button cover corners. The name tag accessories and name
tags are supplied with the button modules.
ASSEMBLY METHOD
To assemble the button module in the module holder supports, follow the instructions provided in the GCM EVOLUTION
audio module or video GVM EVOLUTION audio/video module manuals.
BUTTON MODULE CONFIGURATIONS
The button configurations as they appear when the panel is mounted on the wall are shown in the following figure.
The module position depends only on the structure of the panel to be made.
WARNING: Make sure that the buttons correspond to the output terminals if the module is fitted with buttons in the
upper part or in the lower part.
Follow the instructions printed on the circuit carefully to establish the correspondence of buttons and their
respective terminals.
The arrow and the work ALTO (TOP) on the rear sides of the module identify the assembly type in the module holder
supports and therefore the final button configuration.
