General Description
The National Fire Protection Association has published
codes, standards, and recommended practices for the
installation and use of the above appliances. It is recom-
mended that the installer be familiar with these require-
ments, with local codes, and any special requirements of
the authority having jurisdiction.
These bells are intended to be connected to alarm indicat-
ing circuits of UL listed fire alarm control panels. The SSM
series is polarized to enable supervision of the installation
wiring. The SSM bells require 24 VDC and the SSV bells
require 120 VAC.
CAUTION
Do not use in potentially explosive atmospheres.
Do not leave any unused wires exposed.
