In order to guarantee correct functioning of the system components it is important to ensure
that resistance and capacitance of the signal wires are as low as possible. When the distance
between the devices is more substantial, several wires connected in parallel may have to be
used for each signal, in order to reduce conductor resistance. This, however, may lead to an
increase of conductor capacitance. Too high resistance or capacitance of the cables
connecting the control panel to keypads or expansion modules can prevent the devices from
working correctly (e.g. the control panel will be unable to identify devices, absence of devices
will be reported, etc.). When selecting the length of cables, follow recommendations set out in
sections on connection of particular types of devices.
The signal wires of keypad bus (DTM, CKM, COM) must be run in one cable (they must not
be run in separate cables). Also the signal wires of expander bus (DT, CK, COM) must be
run in one cable.
When you make the cabling, remember that there must be sufficient distance between the
low-current wires and the 230 V AC power supply wires. Avoid running the signal cables in
parallel of the 230 V AC supply cables in close vicinity of them.
4.4 Installation of control panel mainboard
The control panel mainboard contains electronic components sensitive to
electric charges.
Before connecting the mainboard to power supply source (battery, alternating
voltage from transformer), you must have finished all the installation work with
regard to hardwired devices (connection of keypads, expansion modules,
detectors, sirens, etc.).
The control panel should be installed indoors, in spaces with normal humidity of air.
The control panel must be protected against unauthorized access.
A permanent (not disconnectable) 230 V AC power supply circuit with protective grounding
must be available at the control panel installation place.
Terminals:
AC
- power supply inputs (18 V AC)
COM
- common ground
OUTn
-
programmable
outputs (n=output number):
high-current:
OUT1 and OUT2 in the INTEGRA24
and INTEGRA 32 control panels; from OUT1 to
OUT4 in the INTEGRA 64 and INTEGRA 128
control panels
low-current:
OUT3 and OUT4 in the INTEGRA24 control panel;
from OUT3 to OUT8 in the INTEGRA 32 control
panel; from OUT5 to OUT16 in the INTEGRA 64
and INTEGRA 128 control panels
Note
: If the high-current outputs are not used, they should be loaded with 2.2 k
Ω
resistors.
