1x2x1,5+0,8J-Y(st)Y, 1x2x0,8+0,8J-Y(st)Y or 1x2x1,5+0,8J-H(st)H, 1x2x0,8+0,8J-H(st)H
coded cables should be used. While cabling (starting from Loop + terminal), cable
’s earth line
must be connected to appropriate earth terminal in the control panel (See Annex-B, Figure-2).
This earth line should be installed throughout all detectors and call points. Earthing cables
should be wired after placing detectors and/or call points and line should be ended. When a
return is performed to (Loop -), earthing line should be done as it is shown in Annex-B,
Figure-2 and line is ended.
4.4 Panel PC Connection
4.4.1 PC Port
Cable connection between panel and PC for data communication is plugged into the PC
Socket which found on front panel of (See Annex-B, Figure-11). The communication cable
shown in Annex-D must be used for communication with computer.
4.4.2 Write Enable Switch
Write enable switch has two positions as
“ON” and “OFF”. (Annex-B, Figure-8) When the
panel is energized while the switch is OFF, the panel runs previously saved data. When the
panel is energized while the switch is ON, panel operation modes appears on the screen.
More details are provided in Section-8.
4.5 Remote Control Inputs
There are remote control inputs on the panel which are likely to control the panel remotely by
the help of any remote button. One terminal of the button is connected to the desired input
and other one is connected to GND. (See Annex-B, Figure-6). It should be used the cable with
this code; 2x1,5 N2XH or 2x1,5 NYY for remote control input line.
AL : Reactivates alarm condition, sounders and relays which was silenced and positioned
by Silence Alarm.
FLT : Activates fault condition.
RS : Resets the panel.
SIL : Silences sounders and returns the relays to their initial position.
5- PANEL OUTPUTS
5.1 Sounder Outputs (4 Units)
The panel has 4 sounder outputs rated 24 V DC 500mA. In order to monitor the line against to
open or short circuit conditions, normally 16 V DC reverse voltage is seen from the sounder
outputs. During fire alarm outputs are driven by 24 V DC (Annex-B, Figure-4). Current driven
more than 0.5A leads the panel into the fault condition.
2x1,5 N2XH or 2x1,5 NYY cable should be used for the sounder line. 10KOhm resistor,
located on sounder outputs from factory default is used as end-of-line resistor and must be
connected to the end of the sounder line. Otherwise, open circuit fault is monitored on the
sounder line of panel. In case of any open circuit or short circuit faults occurred, it can be
displayed on the screen of panel with the line number.
