Connecting hardwired devices
The panel has five screw terminals, two battery terminals, and two telephone
connections. The screw terminals connect the AC power, sirens, and or hardwired
detectors.

Program sensors and devices before you install them. Follow the instructions in
“Sensors” on page 31 to add the sensors to panel memory.
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 is set up for interior siren operation (status and
alarm sounds). The HW1&2 DC out terminal 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 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.
Hardwired interior siren
Interior sirens must always be wired with a resistor in the circuit. For circuit
supervision, which allows the panel to detect if the siren wire is cut (open), the
hardwired siren supervision option must be turned on.
Note:
Do not install the resistor at the panel terminals. This does not provide
supervision of the wire.
Connect the hardwired interior siren (13-374) to the panel using a 4.7 kohm resistor
(included with the siren) as shown in Figure 5 on page 16. The resistor must be
connected across the siren wires as close to the siren as possible.
