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.

47 kohm resistors
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
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.
Full line seizure wiring with one premises phone
If a single phone is all that exists on the premises, full line seizure
can be accomplished without an RJ31X.
1.
Disconnect the phone from the premises phone jack and plug
it into the panel PHONE jack. This jack is disconnected
automatically whenever the panel reports.
2.
Connect the included phone cord to the panel LINE jack and
the premises phone jack.
If a customer adds phones or other phone devices to another
phone jack, full line seizure no longer exists. Inform them to
