General Description
The National Fire Protection Association (NFPA) has published
standards and recommended practices for the speakers described
in this manual. As a result, the installer must be familiar with
these requirements as well as all local codes and special require-
ments of the authority having jurisdiction.
SP300 series speakers can be operated with distribution amplifiers
having an output voltage of either 25 volts or 70.7 volts.
The speakers operate at any one of four input power levels. The
output sound level is selected at the time of installation, but can
be changed, if necessary.
The speaker is also equipped with a capacitive input to allow for
DC supervision.
Installation
All wiring must be installed in compliance with the National
Electrical Code (NEC) and applicable local codes as well as
special requirements of the authority having jurisdiction, using
the proper wire size. This also includes all applicable NFPA
Standards, ANSI/UL 480, and NEC 760.
Electrical
. Connect the speaker as shown in Figure .
NOTE:
Do not loop electrical wiring under terminal screws.
Wires connecting the device to the control panel must
be broken at the device terminal connection in order to
maintain electrical supervision.
