Interior Piezo Siren (30-006)
Panel terminal 8 (OUT2/OC) is an open-collector (switched path-to-ground),
programmable output that can handle up to a 200 mA current.
The default setting (01710) activates the output for status and alarm tones, which
allows for a piezo siren connection without changing the output configuration
number.
Connect the piezo siren to the panel terminals with a 2k end-of-line resistor as
shown in Figure 14 below.
Note : Piezo siren connections to terminal 8 require a 2k end-of-line resistor that
can be located at the panel since it does not supervise the circuit.

Note
: If using an external power supply instead of panel terminal 4, the supply
voltage must be limited to 9.5 VDC maximum and the negative side of the power
supply must be connected to panel ground (terminal 3).
Connecting Siren Drivers, Self-Contained Sirens, and
Bells
Power for a siren driver, self-contained siren, or bell can be connected to panel
terminals 7 (OUT1/+12V) and 3 (GND).
