Electronic unit Type 12B2 for series 1200 panels

INTRODUCTION

With the Digit Digit 2 Wires electronic unit Type 12B2 it is possible to
build series 1200 audio panels with alphanumeric keyboard and dis-
play complete with 2-line, 16-character each, display. 

The electronic units are to be used with series 1200 plates and
components, supplied separately. 

Selection of the elements starts with the plate for the standard electro-
nic unit, continuing with the addition of any extra plates that make it
possible to expand the standard modules. To complete the panel, the
box and frame versions are selected according to the type of panel
installation; surface wall-mounted or flush-mounted.

DESCRIPTION

Type 12B2 corresponds to the electronic unit for building an electronic
audio plate with alphanumeric keyboard and display. 
This unit provide the facility to create exclusively audio door entry instal-
lations with only 2 polarised wires to the cable riser.
The entrance panels are designed to operate either alone or together
with other entrance panels by interconnecting the specific terminal
boards; a maximum of 2 additional panels can be connected in parallel
with the main panel by adding one additional wire from one entrance
panel to the next. (no more than 3 panels per installation).
Electronic entrance panels can also generate different call codes by
means of the numerical keypad, with values from 1 to 9999. A maximum
of 200 users can be configured in the system.
Facility to connect one interphone to another interphone with the same
call (max. 2 interphones connected in parallel).
The front of the panels feature "External Volume - 2", "Internal Volume
- 3" and "Audio Balance - 1" controls, which are preset in the factory. If
necessary we recommend exclusively adjustment of "External Volume"
and, if necessary, adjustment of "Balance" in the case of feedback on
the speech unit, turning the specific trimmer slightly clockwise or anti-
clockwise until the feedback howl is eliminated. In addition, the entran-
ce panel can be programmed directly from the keypad for the technical
parameters programming phase.

INSTALLATION

The assembling and the installation of the electronic units for the 1200

series plates require the following phases:

1- Define the plate for the electronic base unit and possible additional

plates (see components on page 3).

2- Define the back boxes and the frames for the surface wall-mount or

flush-mount installation (see accessory on page 4).

3- Install the flush-mounted wall box or surface-mounted wall box at

suitable height. Route the wires through the hole at the bottom of the
box.

4- Fix the rainproof cover on the back box.
5- Fix the terminal box of the base module to the module holder frame

of the entrance panel.

6- Connect the terminal block to the system as shown in the wiring dia-

gram.

7- Fix the module holder frame to the back boxes
8- Connect the electronic unit of the base module to the plates with

name-tags.

9- Insert the electronic unit and the additional modules in the module

holder frame of the entrance panel.

10-Insert the microphone of the electronic base unit in the module hol-

der frame of the entrance panel (Fig. 8, Part 1).

11- Program the entrance panel.
12- Insert the external plate of the electronic unit in the module holder

frame and the additional entrance panels in the remaining module
holder frames.

13- Close the panel

BASIC MODULES

The basic modules comprise: an electronic unit and a connection termi-
nal block. The electronic unit is equipped with a speech unit, a backlit
alphanumeric display, a keypad, and wiring for connecting the terminal
block.

- It is convenient to fit close to the supply voltage source a proper bipo-

lar type switch with 3 mm separation (minimum) between contacts.

- Before connecting the set, ensure that the data on the label corre-

spond to those of the mains. 

- Use this set only for the purposes designed, i.e.for electric door-open-

er systems. Any other use may be dangerous. The manufacturer is not
responsible for damage caused by improper, erroneous or irrational
use. 

- Before cleaning or maintenance, disconnect the set.
- In case of failure or faulty operation, disconnect the set and do not

open it.
