InstallatIon

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 re,

use only No. 26 AWG or larger telecommunication line cord, such as DMP Model 356 Series Phone Cords.

17.2 J10 893A or 277 Connector

Connect an 893A Dual Phone Line Module or Model 277 Trouble Sounder to J10 on the panel. Refer to the 893A

Installation Sheet (LT-0135) or 277 Installation Sheet (LT-1304) for complete information.

17.3 Notication

The user must not repair registered terminal equipment. In case of trouble, immediately unplug the device from the

telephone jack. The factory warranty provides for repairs. Registered terminal equipment may not be used on party

lines or in connection with coin telephones. No tify the telephone company with the following information:

a. The particular line(s) where the service is connected

b. The FCC registration number as listed in Section 17.5

c. The ringer equivalence

d. The device make, model, and serial number

17.4 Phone Line Monitor

The XR150/XR350/XR550 Series panel has a built-in telephone monitor that monitors the phone line voltage to verify

the connection to the central ofce. 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

to determine if panel is seizing the line:

1. Unplug phone cord from RJ31X

2. Place butt-set on pins 4 and 5

3. Listen for dial tone. With dial tone present, lift either wire from pins 1 or 8

4. Listen for dial tone again. If the dial tone is present, RJ31X wiring is correct. If no dial tone is present, the

RJ31X wiring is backwards. Rewire so dial tone is coming IN on 4 and 5.

If you still have trouble with the phone line, you may need to replace the RJ cord. If the dial tone is still not

present, swap out the RJ31X phone block.

17.5 FCC Registration

The Model XR150/XR350/XR550 Series complies with Part 68 of the FCC rules and the requirements adopted by the

ACTA. On the outside of the enclosure of this equipment is a label that contains, among other information, a product

identier in the format US:CCKAL00BXR550. If requested this number must be provided to the telephone company.

A plug and jack used to connect this equipment to the premises wiring and telephone network must comply with the

applicable FCC Part 68 rules and requirements adopted by the ACTA. See installation instructions for details.

The Ringer Equivalence Number (REN) is used to determine the number of devices that may be connected to a

telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming

call. In most but not all areas, the sum of RENs should not exceed ve (5.0). To be certain of the number of devices

that may be connected to a line, as determined by the total RENs, contact the local telephone company.
