signals in the TTL (0 V, +5 V) standard, hence, a special cable of SATEL manufacture must
be used to connect the panel and computer RS ports. The cable includes a converter
changing this signal into a standard corresponding to the RS-232 interface in the computer
(-12 V, +12 V). The data can be transmitted through the cable in both directions.
The CA-6 control panel should be installed in an enclosed space with normal humidity of air.
The space should be fitted with an available permanent (not detachable) 230 V power supply
circuit with protective grounding.
The control panel can be mounted in the CA-6 OBU housing (this housing comprises
a transformer designed for operation with the control panel power supply), which permits
installation of a battery with
7 Ah
capacity. Before the housing is secured to the base, it is
necessary to mount inside the housing plastic distance plugs, which are intended for
subsequent installation of the mainboard.
In case the plugs tend to slip out, the catches fixing the plug in the housing need to be slightly
bent aside (Figure 3). When inserting the plug, press the central part of the head firmly in so
that it is blocked in the housing hole. It is advisable to make sure that the plug, when
pressed, does not slip out from the opening. During installation of the housing, be careful so
as not to damage the wires which will be passed through the hole in its back panel.
When the housing is secured, you can install the control panel main board and proceed to
making the connections.
IMPORTANT: Do not connect the mains power supply and the
battery
, until all the remaining
connections are completed.
The control panel is power supplied from 230 V AC mains. Negligence or wrong
connection may result in electric shock and pose a threat to life!
Therefore, be particularly careful when hooking up the control panel. In the
process of installation and connection of the control panel, the cable to be used
for mains supply must not be alive!
Connection of keypad
The keypad should be connected to the system with a four-wire line, using the COM, +KPD,
DATA, CLK terminals on the panel. Where standard wire is used, the cable length can be up
to 200 m. Do not use screened wires.
It is recommended to use an untwisted unshielded cable 8x0,5 mm
2
(do not use twisted pair
cables). With recommended cable, the following distances between keypad and control panel
may be used to ensure appropriate power supply:
Distance
Lead
No. of cores
to 100 m
Supply and common ground
CLK and DATA signals
2 x 1
2 x 1
from 100 m
to 200 m
Supply and common ground
CLK and DATA signals
2 x 2
2 x 1
The keypads may only be supplied from the +KPD connector of the control panel.
This
output can also be used to supply detectors connected to the keypads, if the total current
value of 1.5 A is not exceeded.
