Wiring Phone Lines - GE Simon XTi Installation Manual

The HW1 I/O terminal is dual purpose and can be used for
either siren or hardwired contact connections. The HW2 in
terminal is an input only.
Interior sirens
From the factory, the HW1 I/O input (terminal 1) is set up for
interior siren operation (status and alarm sounds). The HW1&2
DC out (terminal 2) provides the positive (+) voltage.
Note: The total current available from the HW1&2 DC out
terminal is 250 mA at up to 120ºF (49ºC). A 24-hour battery
standby for UL requirements will be met with a maximum load
of 250 mA.
With Hardwired Siren Supervision turned on, sirens connected
to HW1 I/O are supervised and require a 4.7-kohm resistor in
the circuit. If this terminal is not used, turn Hardwired Siren
Supervision off.
Exterior sirens
For an exterior siren, change the HW1 setting in the System
Options programming menu. See wiring diagram.
Note: Not investigated for and may not be used in a UL Listed
installation.
Hardwired contacts
You can connect hardwired reed switches (normally closed
loop only) to HW1 I/O (if not being used for a hardwired siren)
and/or HW2 in (terminal 3).
Connect only normally closed (NC) reed switches to HW1 I/O
and/or HW2 in. Other types of hardwired detectors should not
be used.
The total resistance of the wired loop must not exceed 3 ohms.
This allows you to use up to 200 ft. (61 m) of two-conductor,
22-gauge stranded wire.
Connect hardwired reed switches to the panel using a 47-kohm
resistor (not a 4.7-kohm resistor) as shown in Figure 4 below.
The resistor must be connected at the last switch in the circuit.

Note: Do not install the resistor at the panel terminals. This
does not provide supervision of the wire.

Wiring phone lines

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, as other devices on 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 the line seizure for UL
installations.
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.
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
