Label
Name
J4 Primary Ethernet port (Eth1) that can permanently connect the
CLSS Gateway mainboard board with the CGW-MB services or
a Modbus client/server.
The Ownership Code (OC) on it confirms the ownership of the
board. It should be registered in the CLSS Site Manager during
the first time installation of the CGW-MB.
Cable: CAT 5 standard Ethernet cable with RJ45 connector
J3 Secondary Ethernet port (Eth0) providing a TCP/IP connection
to a configuration computer.
Cable: CAT 5 standard Ethernet cable with RJ45 connector
P5 Receives the alarm data and device data from an RS-485 port
of a panel.
P1 Receives the alarm data and device data from an RS-485 port
of a panel.
P4 Receives the alarm data and device data from a UART/TTL port
of a panel.
P7 Transfers fire-related and device-related data from the panel to
the CLSS Site Manager through the CLSS Gateway mainboard.
It also helps in administering the fire detection system.
Connects the CLSS Gateway mainboard board to a panel's RS-
232 port.
If the connected panel supplies power, the CLSS Gateway
mainboard would get power from the panel through the RS-
232 port.
P2 Connects to an external 24-volt DC power when required. It
uses a power-limited, regulated, power-supply-listed
connection for fire-protective signaling.
Twisted-unshielded pair, 12 to 18 AWG (3.31 mm² to 0.82 mm²)
It is used only when the CLSS Gateway mainboard board is
connected with:
• A network card
or
• When power is not supplied to the NUP connector
J5 Receives the alarm data and device data from a USB port of a
panel.
E4 Wireless antenna
4D 40-pin connector for the compatible cellular module.
