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 8 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.
