By-alarm
01704
By-alarm configurable 8-input expansion module for potential-free
contacts, cord for roller shutter, passive non-piezoelectric shock
detectors, with additional power supply battery status control function.
TECHNICAL CHARACTERISTICS
• Power supply: 12 V ± 20%
• Absorption: 18 mA max
• Input lines: No. 8 with single, double and triple balancing
• Connections: with 4 wires to one of the serial ports for connection to the RS485 bus
• Operating temperature: -10..+40 °C (indoor use)
• Degree of safety: 2 (EN 50131-3)
• Ambient class: II (EN 50131-3)
• The 8-input expansion module 01704 is compatible with the control units 01700,
01700.120, 01703 and 01703.120 having firmware version 1.2 or later; before
installing the device, use the keyboard 01705 to check the firmware version of
the control unit in the system. Alternatively, check that the tracking code shown
on the label of the control unit on which you are installing the device is equal to
or greater than XXXXXXXXXX1.02.
INSTALLING THE EXPANSION MODULES
The module is connected to the control unit to one of the bus serial ports, following
the instructions given in the control unit's installation manual and respecting the
warnings.
• For installation, use halogen-free shielded cables suitable for installation with
Category 1 power cables (U0 = 400 V) such as cable art. 01733 (2x0.50
mm
2
+2x0.22 mm
2
).
• For the power supply, use wires with a minimum cross-section of 0.50 mm
2
observ-
ing the c and - polarity.
• Connect the signal cables A and B using conductors with a minimum section equal
to 0.22 mm
2
.
• The length of the connection with the wired sensors must not exceed 100 m.
• The shielding must be connected to the negative on the control unit side and left
free on the expansion module side.
Input zones
The module has 8 inputs and 2 push-buttons for protection against opening the
enclosure and against tearing it off the wall. The push-buttons protecting against
opening and against removal on the zone expansion card can be cut off by closing the
relevant jumpers alongside the buttons. The power supply to any sensors is carried
by the 2 terminals marked
+
and
-
, protected by the
resettable 500 mA fuse F1
next
to the power supply terminals.
Recessed connector
The device has a recessed connector;
it must not be used under any circumstances
as it is for internal testing and firmware updating; improper use may damage the
circuit.
ADDRESSING THE EXPANSION MODULES
For them to be recognised by the control unit, the expansion modules need to be
addressed by setting the DIP-switches on the printed circuit board; the settings that
can be made are listed in the following table:

Caution: The maximum number of expansion modules that can be installed
depends on the type of control unit used.
If the addressing made with the DIP-switches is changed with the module
switched on, to make it operational you need to press the push-button PB2 or
power cycle the device.
Amber LED
The amber LED on the expansion module lets you control functionality as follows:
•
On steady
: module properly powered but no serial communication.
•
Blinking at a frequency of 1 s
: module powered correctly and receiving serial
communications but these are sent with an incorrect address or no configuration
of the device in the control unit.
•
Blinking with one short pulse every second
: module powered properly and
correct serial communication.
