General
The National Fire Protection Association has published
standards and recommended practices for the installation
and use of the appliances described in these instructions. It
is recommended that the installer become familiar with
these standards and practices, local codes, and any special
requirements of the authority having jurisdiction.
The speakers can operate at any one of four input power
levels at either of two input voltages. The system voltage
and sound power levels are selected at the time of installa-
tion, but can be changed, if necessary.

The speaker is also equipped with a capacitive input to al-
low for DC supervision.
An attached 24 VDC strobe at 110, 75, 15, or 15/75 candela
(cd) is also included with the speaker. Although they are
assembled into a unit, the strobe and speaker are electri-
cally independent and require separate power sources.
Strobes can be powered by means of a full-wave rectified
unfiltered supply.
