24 Simon XT TableTop Control Panel Installation Manual
Connect hardwired reed switches to the panel using a 47 kohm resistor (not a 4.7
kohm resistor) as shown in Figure 5. The resistor must be connected at the last
switch in the circuit. Do not install the resistor at the panel terminals. This does
not provide supervision of the wire.

Telephone connections
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.
Use the RJ31X (CA-38A) jack 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.
To wire a full line seizure with an RJ31X, see Figure 6 on page 21 and do the
following:
1. Run a four-conductor cable from the premises Telco block to the RJ31X.
