The control module circuit board is the same for panels with pushbuttons or with keypad/display.
In the starting or whenever any identification switch is changed, the system identifies whether the
panel has pushbuttons or keypad/display.
The control module is multipanel. This means that is possible to install up to 15 modules (15
accesses) in the same bus. It is necessary to identify them with a different number by means of the
dip-switch. The number 0 is not allowed.
Each panel can independently of others be a keypad/display or pushbuttons one in the same
installation.
In a pushbuttons panel, the programmable parameters can be set connecting a keypad/display
panel, making it to identify the keyboard, entering the configuration menu to program what it is
desired and then retiring the keypad/display panel. It will be necessary to trigger the automatic
identification at the end so that the system returns to detect the pushbuttons (this can be done by
changing any of the id. switches).
A keypad/display panel can support simultaneously up to 12 pushbuttons that must be connected
in rows 1 to 4 and columns 4 to 6. These pushbuttons can have assigned any monitor code by
means of the function of pushbuttons codification at the configuration menu. They will be the
pushbuttons of positions 4-5-6, 10-11-12, 16-17-18, 22-23-24.
Installations with general access can be performed using SDL's Visualtech.
The general access (external) can call all the monitors and interior access only to its SDL (building
or raiser).
The maximum number of monitors for SDL is 99. You can install up to 63 SDL's.
In a
keypad/display
In a pushbuttons external panel it is necessary to encode properly.
ADJUSTMENT OF INSTALLATIONS WITH SDL
It is necessary to follow this set procedure to prevent couplings in an installation with SDL Visualtech:
Adjust the balance potentiometer of the audio module of all the internal panels so that the audio
works without couplings.
Adjust the potentiometer POT of the farthest SDL at its minimun value (-).
Adjust the balance potentiometer of the audio module of the general access (external panel) using
a monitor belonging to the farthest SDL. Repeat if more than one general access.
Adjust (only if necessary) the potentiometer POT each other SDL´s to proper audio between a
monitor belonging to the SDL and the general access.
