8.
Voltage-free output NC (or NO) for information about alarm
– 2 leads
(e.g. YnTKSY) from P14 terminals. The H2 jumper allows to select NC (default)
or NO output.
9.
Voltage-free output NC (or NO) for information about defect
– 2 leads
(e.g. YnTKSY) from P15 terminals. The H3 jumper allows to select NC (default)
or NO output.
10.
Voltage-free output NC (or NO) for information about vent opening
– 2 leads
(e.g. YnTKSY) from P16 terminals. The H4 jumper allows to select NC (default)
or NO output.
11.
Mains 230 V, 50 Hz
should be connected to the terminal strip on the unit
assembly board. The power supply for the unit should be separate (units only on
the mains line), protected by means of a properly marked overload circuit breaker
in
the
switching
station.
The
recommended
circuit
breaker:
I = number of control units * 4 A, or * 6A for series of type 8A. It is not
recommended to connect more than eight units on a single line. Do not protect
the line by means of a GFCI (RCCB) circuit breaker.
12.
24 V power supply from batteries
(P4, P5). The batteries should be connected
in series, taking polarity into account. Make the connection after the control unit
has been launched by use of mains power supply.
13.
Large systems
– connecting multiple control units
. In order to increase the
number of sensors, ROP buttons or actuators connected to the system, one can
connect multiple control units.
To relay an alarm from one control unit to another, use the P14 alarm output
terminal and the P13 alarm input terminal with P12 power supply.
Do not connect output lines [to actuators] of different modules.
Control units can be connected together into ventilation sections. To do this,
connect in parallel the P6 ventilation terminals of all control units in a section: U-
up, D-down, ground-joint. Connect the weather monitoring unit only to one (any
one) control unit in the section, to P7 terminals.
When connecting the weather monitoring unit to more than one ventilation
section, connect individual units in parallel.
Important! - connect the P7 terminals on the left to one line, and the ones on the
right to the other line - do not cross!
14.
Remote door controls
. The control unit is also adapted to operating in the
remote door control mode. To switch on the door control mode, use the SW1-6
switch (set it to ON). Connect electromagnetic door locks to the P8 terminals.
15.
Unlocking electric locking drive\ activation of alarm boxes
. The control unit
can work in the release mode of interphone installation and / or triggering alarm
boxes. In order to activate the mode, the switches no. SW1-5 and SW1-6 should
be set to the ON position.
16.
Other devices activated only in the alarm state
The mcr 9705 control unit has the option of connecting external devices supplied
with 24 V = voltage, working in the alarm state, such as the SA-K7 optical-
acoustic indicators. They can be connected in one of two options:
- devices with their own power source should be connected with 2 wires
(YnTKSY) via NC isolated (or NO) voltage output on terminal P16 (jumper H4 is
used to select NC output - factory or NO),
