Interior Sirens - Interlogix XTI-5 Installation Manual

Figure 5: Wiring terminals
Program sensors and devices before you install them. Follow the instructions in
"Sensors" on page 41 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 6 on page 17. The resistor
must be connected across the siren wires as close to the siren as possible.
