INSTALLATION
15.3 OVC LEDs
The Overcurrent LED (OVC) lights Red when the devices connected to the Keypad Bus and LX-Bus(es) draw more
current than the panel is rated for. The LED(s) turn a steady Red when lit. When the OVC LED(s) light red, the
appropriate LX-Bus(es) and Keypad bus are shut down.
• The OVC LED located to the left of the 893A connector indicates overcurrent for the Keypad Bus (Terminals 7-10
and PROG header), XBUS, and LX500-LX700.
• The OVC LED to the right of the J24 Cell Module connector indicates overcurrent for LX800-LX900.
J1 Ethernet Connector (Panels with Network/Encryption only)
16.1 Description
The Ethernet Connector is available on the XR150/XR550 with network or encryption to connect directly to an
Ethernet network using a standard patch cable. The Ethernet Connector supports 100MB/s full duplex operation and
the maximum impedance is 100 Ohms.
16.2 Ethernet LEDs
The two LEDs, located on the top edge of the J1 Ethernet Connector, indicate
network connection. The right, Link LED lights up green to indicate a valid
receive connection from the host network. The yellow LED lights when
connected to a 100Mb network and is off when connected to a 10Mb network.
16.3 Network Transient Suppression
The Model 270 Network Transient Suppression Module to provide transient surge protection for the J1 Ethernet
Connector. Refer to the Model 270 Installation Sheet (LT-1316) for complete information.
J3 Telephone RJ Connector
17.1 Description
Connect the panel to the public telephone network by installing a DMP 356 RJ Cable between the panel J3 connector
and the RJ31X or RJ38X phone block. The maximum impedance is 100 Ohms.
CAUTION -
To reduce the risk of fire,
use only No. 26 AWG or larger telecommunication line cord, such as DMP Model 356 Series Phone Cords.
17.2 J10 893A or 277 Trouble Sounder Connector

17.4 Phone Line Monitor
The XR150/XR550 Series panel has a built-in telephone monitor that monitors the phone line voltage to verify the
connection to the central office. Figure 11 and the table below identify the phone block pin layout, wire numbers,
and colors.

The wires on the RJ31 that feed pins 4 and 5 should be the ONLY wires on the D-marc. All other house phone wiring
should be tied to pins 1 and 8 coming back from the RJ31.
Dial tone must come into RJ31X on pins 4 and 5 and go back to house phones from pins 1 and 8. Follow these steps
