For full line seizure, install an RJ31X phone jack on the premises phone line
so the panel is ahead of all phones and other devices on the line. This allows
the panel to take control of the phone line when an alarm occurs, even if the
phone is in use or off-hook.
Note: Connecting the panel to an analog line off the phone switch places the
panel ahead of the phone system, preventing panel access from phones on
the premises. However, the panel can still be accessed from offsite phones.
If an analog line is not available, contact a telecommunication specialist and
request an analog line off the phone switch (PBX mainframe) or a 1FB
(standard business line).
To connect a phone line to the panel using an RJ31X/CA-38A jack:
1. Run a four-conductor cable from the TELCO protector block to the jack
location.
2. Connect one end of the cable to the jack.
3. At the TELCO protector block, remove the premises phone lines from the
block and splice them to the black and white (or yellow) wires of the 4-
conductor cable.
4. Connect the green and red wires from the 4-conductor cable to the TIP (+)
and RING (-) posts on the block.
5. Check the phones on the premises for a dial tone and the ability to dial out
and make phone calls. If phones do not work correctly, check all wiring and
correct where necessary.
Connecting the phone line to the panel with a DB-8 cord
After installing the RJ31X jack, you are ready to connect the phone line to the
panel. A DB-8 cord (not included) uses a plug at one end for connecting to the
RJ31X module and flying leads on the other end for panel terminal connections.
To connect the DB-8 cord to the panel terminals and RJ31X jack:
1. Connect the green, brown, gray, and red flying leads from the DB-8 cord to
panel terminals 25, 26, 27, and 28.
2. Insert the DB-8 cord’s plug into the RJ31X.
3. Check the phones on the premises for a dial tone and the ability to dial out
and make phone calls. If phones do not work correctly, check all wiring and
correct where necessary.
