Troubleshooting guide

Phone Line 1 Trouble- XR200, XR200/485 & XR2400F

The panel is looking for a SHORT between pins 2 & 7 on its' RJ-45 connector (J3), EXCEPT

WHEN a Model 893 or 893-A Dual Phone Line Module is installed on the panel.

If you ARE NOT using a Model 893 or 893-A Dual Phone Line Module-

Know this:

• RJ supervision is achieved by placing a jumper wire across pins 2 & 7 of the RJ-31X.

• The panel is looking for a SHORT between pins 2 & 7 on its' RJ-45 connector (J3).

• The panel looks for this short on pins 2 & 7 every two minutes.

To correct this condition:

a) Make sure the jumper wire is installed across pins 2 & 7 of the RJ-31X.

b) Check the RJ cable for continuity. There may be a broken wire. If so, replace the RJ

cable with DMP Model 356-2.

c) Make sure that the RJ-31X pin-out is correct.

If you ARE using a Model 893 or 893-A Dual Phone Line Module-

Models 893 and 893-A modules monitor telephone line voltage. When the voltage falls

below 3 VDC, the panel generates a PHONE LINE 1 or 2 TRBL. Here are some things to

check:

-Check phone line voltage

a) Set multi-meter to DC voltage and reset the panel using the J16

b) With the panel J3 still connected to RJ-31X, place meter-leads on pins 4 & 5. If properly

wired for line seizure, this should be your incoming dial tone.

c) Check voltage. When the panel is ON-HOOK (not dialing) this voltage should read

somewhere between 45 and 55 VDC.

d) Make the panel go OFF-HOOK (an easy way to do this is to remove and replace the

TAMPER [J4] jumper) and read the phone line voltage again.

NOTE: If the phone line voltage drops below 3 VDC, the problem lies with the phone line. If

it does not drop below 3 VDC, try BYPASSING THE 893. To do this:

a) Place a jumper wire across pins 2 & 7 of the RJ-31.

b) Disconnect the short RJ cable (between panel's J3 to 893's J1) from the panel J3

c) Unplug RJ cable from 893's MAIN (BACKUP for PH LINE 2 TRBL), plug into panel's J3

d) Wait up to TWO minutes for PH LINE TRBL to clear

Does PH LINE TRBL clear?

• YES - Replace 893 Module. BE SURE TO POWER DOWN THE PANEL FIRST

• NO - Enter PROGRAMMING and Initialize EVENTS. This should clear the display. Wait

at least TWO minutes after Initializing EVENTS to make sure that the PH LINE TRBL does

not return.

TECH NOTE: Initializing EVENTS erases ALL EVENTS in the Event Buffer.
