ACTUATOR RELAY MODULE ART. 1256
Intelligent device for controlling a 10A relay (fitted) for gener-
al uses. Art. 1256 may be used in B/W and colour Simplebus
Kit systems, as well as in B/W Simplebus 2 and Simplebus
Color systems. Fit a max. of 10 actuator relay modules Art.
1256 on the outgoing bus line to an audio or audio/video
external unit. Fit a maximum of 30 actuator relay modules
Art. 1256 on the outgoing bus line to a mixer/power supply
unit Art. 4888, 4888C. To use the actuator relay module in
Simplebus 2
or Simplebus Color systems DOWN-
STREAM of Art. 4888, 4888C see the note on page 2.
ART. 1256 OFFERS THE FOLLOWING SIX FUNCTIONS,
DEPENDING ON THE POSITION OF JUMPER JP1:
A) Call repetition function.
JP1 as illustrated in Fig. 1.
The relay is operated by closing the C.NO. con-
tact in response to a call from the switchboard,
external unit or landing; this happens only if the
user code for which you wish to repeat the call is
set using the Dip-switch (e.g. to activate lights,
ringtones, paging function, CCTV alarm con-
tacts, etc.). On receipt of a call from the external
unit or the landing, single closure of the relay takes place. In
response to a call from the switchboard, the relay closes twice.
Intercom calls are not repeated.
The actuator relay module can also be used alone, if you
want to close the C.NO. contact rather than repeat the call to
an apartment when the external unit calls the user code set
on Art. 1256.
The relay closure time is set to approximately 2 sec. To set
the user code by means of a Dip-switch, see table on page
10. See diagrams in par. A: SB2/K - BK/AAC - SB2/MB.
B) Activation function on switchboard call pushbutton.
JP1 as illustrated in Fig. 2.
For use only with systems not equipped with
switchboard Art. 1998/A. The relay is operated
by closing the C.NO. contact in response to a
switchboard call from an entry phone or video
entry phone (e.g. to activate the following inde-
pendently, using a specific command: lights,
CCTV
alarm
contacts,
entrances without external units or other devices). The relay
closure time can be programmed using a Dip-switch (see
table A). The function can be used only when the system is
free. See diagrams in par. A: SB2/K - BK/AAC - SB2/MB -
SB2/L - SB2/N - SB/G.
C) External unit light function / Stair light function.
JP1 as illustrated in Fig. 3.
The relay is operated by closing the C.NO. con-
tact in response to a call from an external unit to
any address, on internal ignition from a video
entry phone (e.g. to automatically activate
lights, CCTV alarm contacts, etc.). The relay
closure time can be programmed using a Dip-

switch (see table A). See diagrams in par. A: SB/G, SB2/L,
SB2/N.
D) Secondary door lock release function (without exter-
nal unit).
JP1 as illustrated in Fig. 4.
The relay is activated when the door lock
release pushbutton is pressed, if the user code
of the entry phone or video entry phone from
which the command is sent is within the range
defined using Dip-switches - see table B (e.g. to
activate a second door lock release using the
door lock release command for entrances with-
out an external unit). The relay closure time is set
to approximately 2 sec.
See diagram in par. A: SB2V/EN/155PX/G.
E) Activation function on Actuator pushbutton.
JP1 as illustrated in Fig. 5.
The relay is operated by closing the C.NO. con-
tact in response to a Generic actuator call from
an entry phone or video entry phone (e.g. to acti-
vate the following independently, using a spe-
cific command: lights, CCTV alarm contacts,
driveway gates, entrances without external
units or other devices). The relay closure time
can be programmed using a Dip-switch (see table A). The
function can be used at all times except when a conversation
is in progress from an entry phone or video entry phone other
than your own. All Art. 1256 modules set for use with this func-
tion are activated simultaneously when the pushbutton on the
internal unit is pressed. See diagrams in par. A: SB2/K -
BK/AAC - SB2/MB - SB2/L - SB2/N - SB/G.
F) Activation function on Actuator with code pushbutton.
The function may NOT be used in Simplebus Kit systems.
JP1 as illustrated in Fig. 6.
The relay is operated by closing the C.NO. con-
tact if the pushbutton pressed on the entry
phone or video entry phone has been pro-
grammed (using the hand-held programmer Art.
1251/A) to send the actuator call with the code
of the actuator in question (e.g. to activate the
following independently, using a specific com-
mand: lights, CCTV alarm contacts, driveway
gates, entrances without external units or other devices). The
closure time of the relay is fixed at 2 sec. The function can be
used at all times, except when a conversation is in progress
from an entry phone or video entry phone other than your
own. To set the user code by means of a Dip-switch, see
table on page 10. See diagrams in par. A: SB2/K - BK/AAC -
SB2/MB - SB2/L - SB2/N.
The relay for Art. 1256 operates in BISTABLE mode,
changing its status at every command; if the power supply is
cut off, it returns to the C.NO. position and remains there,
even after the power is restored.
