9 INPUT AND OUTPUT CIRCUIT CONNECTING TERMINALS
The control panel is equipped with a set of connecting terminals designed for connection of alarm
installation wires, external devices and mains power supply. The terminals enable connection of
wires of a maximum diameter at 1.2 mm and a cross section at 1.5 mm
2
. It is recommended to use
screened conductors approved by appropriate certification authorities. The arrangement of the
terminals with their marking is presented in Fig. 2.
Mains power supply: The cable terminals (with the F3 fuse) are provided to connect 230 V/ 50 Hz
mains wires and a protection wire – item 3 in Fig. 2.
Detection lines: The detection lines should be connected to the 4…6 pairs of connectors with
properly marked polarisation. The line 5 and 6 can be configured as a detection or alarm one
depending on the S9 and S10 jumpers position in accordance with the information contained in Fig.1.
The S9 and S10 jumpers position is detected in the quiescent mode. It is recommended to create
detection lines using a screened cable certified by an appropriate authority, e.g. in Poland – with
YnTKSY ekw 1 x 2 x 0.8 cable certified by the CNBOP. The terminals to connect the cable screens are
placed above the detection line terminals on the control panel cabinet near the bushings - Fig. 2. The
detection lines should be terminated with 10 kΩ end-of-line resistors. Fig. 5 depicts the method of G-
40 base connection in a detection line. In the case of unused lines, the end-of-line resistor is
connected to the control panel output terminals. All supervised lines must be furnished with an end-
of-line resistor – otherwise the control panel will report a fault.
Alarm (controlling) lines. Lines 5 and 6 can be used as alarm lines under a condition that the S9 and
S10 jumpers are set in position 2-3 as shown in Fig. 1. The lines are monitored (as for a break and
short circuit) and designed mainly to connect external acoustic devices. They can be also used for
fire-fighting equipment control. To ensure proper monitoring and controlling of the connected
signalling devices or other equipment, the total line resistance should range from 130 Ω to 10 kΩ. In
the case of an unused line or control of a device of higher resistance, it is obligatory to connect in
parallel a 10 kΩ end-of-line resistor. A diagram showing a detection line connection is presented in
Fig.1. In the quiescent mode, a monitoring voltage is observed in the controlling lines, with
polarisation consistent with the marking shown in Fig. 1 – the diodes connected in series with the
signalling devices are polarised in such a way to block the current flow. In the active state (alarm
mode) the voltage polarisation is changed for the opposite one and the diodes connected to the
signalling devices are in the conducting state.
Fire alarm relay outputs: The relay outputs, activated during a fire alarm, are designed to control
additional protecting devices or to transfer information about the control panel mode to the
monitoring centre. The control panel is equipped with relays marked as PK1÷PK8, their terminals are
connected to the terminal board. Fig. 1 (and the informative label inside the control panel) depicts
the terminal position in the non-potential state (the control panel not power supplied).
PK1÷PK6 –programmable relays assigned by default to the detection lines in such the way that the
L1÷L6 line alarm mode actuates the PK1÷PK6 relays accordingly. It is possible to program
every PK1÷PK6 relay in dependence on any detection line (zone) alarm mode or the
general fault occurrence. In the case of detectors that require a break in the power supply
circuit for the alarm mode reset, it is provided to program any PK1÷PK6 relay in such the
way that the terminals are switched over for the time of the control panel alarm mode
reset (see F.08 RELAY PROGRAMMING).
PK7 – general alarm relay, switches the terminals over at the moment of a 2
nd
stage fire alarm
occurrence, what can be program delays by 0..10 min. Using the DELAY DISABLEMENT (5) it is
possible to disable (switch off) the delay function and obtain immediate actuation.
