HW1 I/O, HW2 in, and HW1&2 DC out terminals
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). HW1&2 DC out provides the positive (+) voltage.
Note: The total current available from the HW1&2 DC out terminal is 250 mA at
up to 120°F (49°C). 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.
LD105 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),
Hardwired Siren Supervision must be turned on.
Note: Do not install the resistor at the panel terminals. This does not provide
supervision of the wire.
Connect the LD105 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 24 The
resistor must be connected across the siren wires as close to the siren as
possible.
