Extension Sounder/Relay (512D/512DR)

Description

Compatible with the “2 wire” BUS and has an 8 way Dip-switch to program the address number of the

device. Up to 3 units can be addressed with the same number (Ex.: 1 intercom and 2 extension sounders to

be operated with the same apartment number). The call tone is different according to the origin of the call

(Main entrance call or local door bell). A two level volume control is available using jumper JP1 (only for

512D, while for 512DR the JP1 is not used and stays in position “H”). Through the jumper JP2 it is possible

to set the number of rings (512D) or the number of relay pulses (512DR) from 1 to 6. The current

consumption on the BUS line is lower than 1mA in stand-by mode. The Art.512DR can also be used as a

“service relay” for the entire BUS, activated by the alarm signal coming from an apartment. To use this

function it is necessary to give the unit the address 255.

- The 512D unit will ring according to the programming (1 or 6 times), or until the intercom handset is

picked up.

- The 512DR unit will operate the relay for 1 or 6 x 2 secs on, 2 secs off ,according to the programming,

except if the intercom handset is picked up.

Local call:

- The 512D unit will ring the number of times the local bell is pressed.

- The 512DR unit will activate the relay each time the local bell is pressed and will remain active as long

as the local bell remains pressed.

In case of an Alarm (only for 512DR addr.255)

The unit 512DR will activate the relay for 1 second (apart from JP2 jumper settings) to start the relevant

service.

Programming

The address of the unit must be programmed by means of the internal 8 way Dip-switch (see conversion

table decimal/binary) and must be the same as the phone or videophone connected in the same apartment.

To use as a service relay activated by the alarm signals sent on the bus, set the address to 255.

The jumper JP1 is used to set the volume of the call tone: position “H” = high, position “L” = low (only for

512D, in the 512DR unit the JP1 must stay in position “H”).

The jumper JP2 enables the configuration of the number of rings or relay pulses: position “A” = 1

ring/pulse, position “B” = 6 rings/pulses.

In order to synchronize the local apartment call with the phone, connect the “LB” terminal with the “LB”

phone terminal.
