Extinguishing Control Panel
Installation and Operation Manual
Page 12
When there are several emergency gas override controls, they should be
connected in series.
(4) Sounder strobe are to be connected to the control panel by two-wire mode, to
signal loop by polarity-insensitive two-wire, and to 24VDC power by
polarity-insensitive two-wire.
Please refer to Appendix 1 for system connection.
Note:
When cabling the emergency start and emergency stop buttons of
emergency gas override control, make sure to connect them according to
the marks on the control panel and emergency gas override control. If they
are reversed, the control panel will not give fault signal of connection error,
and it cannot operate properly.
When cabling gas stop indicator, make sure to connect them according to
the marks on the control panel and gas stop indicator. If they are reversed,
the control panel will not give fault signal of connection error, and it cannot
operate properly.
Save the removed terminal resistor for future use.
5.6 Setting
5.6.1 Setting Address of Zone Control Board
Each zone control board corresponds to a zone (1~6), so each zone has its own
address. Opening the cabinet, there is a pin X2 with marks of 1, 2, 3, 4, 5, 6 on the left.
Short the pin whose address is to be set by a jumper. In Fig. 5-4, it is set as number 4.
Fig. 5-4
Note: The address of zone control board cannot be set randomly. Please set one
number to one board in sequence. It’s not allowed to set several boards with the
same number.
5.6.2 Setting the Initial Address
The control panel communicates with the FACP through polarity-insensitive signal loop.
The initial address of the control panel on the FACP is set through code switch S1 on
the main board of the control panel (Fig. 5-5). It can be set as 1, 21, 41, 61, 81, 101,
121, 141, 161, 181.
Fig. 5-5
To set initial address, open the cabinet, turn the code switch S1 on the main board to
different positions according to initial address number. Details are shown in table 1.
