General Description
The National Fire Protection Association has published
standards and recommended practices for the installation
and use of the listed appliances. It is recommended that the
installer be familiar with these requirements, local codes,
and any special requirements of the local fire authority hav-
ing jurisdiction.
The Multi-Alert sounder and signaling strobe are intended
to be connected to the alarm indicating circuit of a UL-
listed fire alarm control panel. Both are compatible with DC
line supervision. The electronic sounder can be connected

Note 2:
All models can be powered using full wave rectified unfiltered
supplies. Under no circumstances can SS24ADA or
MASS24ADA series devices input voltage exceed 33 VDC or be
less than 16 VDC (16-33Vrms for full-wave rectified, unfiltered
supplies). Under no circumstances can the MA12/24D input

to either 12 or 24 VDC panels. Models SS2415ADA,
SS2475ADA, SS24110ADA, SS241575ADA, and combina-
tion models incorporating these strobes, require 24 volt
panels. Models SS1215ADA, SS121575ADA,
MASS1215ADA , and MASS121575ADA require 12 volt pan-
els. Panels may have full-wave rectified, unfiltered power
supplies. The strobes produce one flash per second (nomi-
nal) with continuous nominal voltage applied.
The MA12/24D is suitable for outdoor applications (-35
