Notification
The user must not repair registered terminal equipment. In case of trouble,
immediately unplug the device from the telephone jack. Registered
terminal equipment may not be used on a shared or public line. Provide
the telephone company the following information:
• The particular lines where the service is connected
• The FCC registration number as listed
• The ringer equivalence
• The device make, model, and serial number
Phone Line Monitor
The XR150FC/XR550FC Series panel has a built‑in telephone monitor that
monitors the phone line voltage to verify the connection to the central
station. Figure 8 and Table 2 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 DMARC. All other house phone wiring should be tied to
pins 1 and 8 coming back from the RJ31.
Dial tone must come in to RJ31X on pins 4 and 5 and go back to house
phones from pins 1 and 8. Follow these steps to determine if the panel is
seizing the line:
1. Unplug phone cord from RJ31X
2. Place a butt‑set on pins 4 and 5
3. Confirm the presence of a dial tone, then lift the wire from either pins 1 or 8.
4. If a dial tone is still present, the RJ31X wiring is correct. If no dial tone is present, the RJ31X wiring is backwards.
Rewire the phone block so the dial tone is coming in on pins 4 and 5, then retest the connection.
If you still have trouble with the phone line after rewiring the phone block, you may need to replace the RJ cord. If the
dial tone is still not present after replacing the phone cord, replace the RJ31X phone block.
RESET and TAMPER Headers
RESET Header
The RESET header is used to reset the panel. To reset the panel when installing the
system, place the jumper across both RESET pins before applying power to the
panel. After connecting the AC and battery, remove the reset jumper.
To reset the panel while the system is operational, install the reset jumper without
powering down the system. Remove the reset jumper after one or two seconds.
After resetting the panel, begin programming within 30 minutes. Otherwise, you
must reset the panel again to enter the PROG menu.
TAMPER Header
The TAMPER header is designed to connect to a tamper switch with a tamper
harness. One or more tamper switches can be mounted inside the panel enclosure
to supervise unauthorized removal or opening of an enclosure. Refer to the wiring
diagram on the enclosure door for correct tamper switch wiring.
If the enclosure is opened or removed while one or more of the system areas are
armed, the system goes into alarm. If all areas are disarmed, a tamper trouble is
indicated by the panel.
