Full Line Seizure - Interlogix XTI-5 Installation Manual

Full line seizure

Full line seizure allows the panel to take over (seize) the phone line, even if
another device on the line is in use. This method requires that the panel be wired
before all other phones, answering machines, computers, or other devices on the
phone line.
Use the RJ31X (CA-38A) jack when wiring for full line seizure. You can then
quickly and easily disconnect the panel from the phone line in case the panel
disables the phone line due to a malfunction.
To wire full line seizure with an RJ31X:
1. Run a four-conductor cable from the premises Telco block to the RJ31X (see
Figure 9 below).
2. Connect the four-conductor cable wire to the RJ31X.
3. Disconnect the green and red premises phone jack wires from the Telco block
and splice them to the four-conductor cable black and white (or yellow) wires.
Use weatherproof wire connectors for these splices.
4. Connect the four-conductor cable green and red wires to the Telco block TIP
(+) and red to RING (-) posts.
5. Connect the phone cord included with the panel to the RJ31X and the panel
LINE jack.
