Wiring a phone line to the panel
You can connect a phone line to the panel for systems monitored by a central
monitoring station or systems that notify users by a voice event notification.
DSL (digital subscriber line) allows the use of multiple devices on a single phone
line simultaneously. For DSL environments, connect the panel line-in jack to an
available phone jack on the premises. You might also need an inline filter to
ensure panel reporting is successful.
Note: Avoid connecting the panel to a standard phone (voice) line in this manner.
Other devices in use at the same time the panel is using the line can prevent
reports from going through.
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. You may need to verify line seizure for UL installations.
Use the RJ31X (CA-38A) jack (Figure 8 on page 26) when wiring for full line
seizure. This lets the user quickly and easily disconnect the panel from the phone
line in case the panel disables the phone line due to a malfunction.
Full line seizure wiring with an RJ31X
1. Run a four-conductor cable A from the premises Telco block D to the RJ31X
B.
2. Connect the four-conductor cable A wires to the RJ31X B.
