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, with local codes, and any special re-
quirements of the authority having jurisdiction.
The electronic Multi-Alert sounder and the signaling strobe are in-
tended to be connected to the alarm indicating circuit of a listed
fire alarm control panel. Both are compatible with DC line super-
vision. The model MA12/24D is suitable for connection to either a
12 or 24 volt panel. Models SS24LO, SS24M, MASS24LO and
MASS24M require 24 volt panels; models SS12LO, MASS12LO and
MASS12M require 12 volt panels. Horn, strobe, or combination
strobe models may be used with panels that have full wave recti-

Note 1: Total current for horn/strobe combinations = horn current +
strobe current; refer to tables 1 and 2.
Note 2: Sound output measured in anechoic room at 10 feet.
Note 3: Sound output measured in UL reverberant room.

fied, unfiltered supplies. The MA12/24D sounder and MASS12/24
sounder/strobes are suitable for outdoor applications (–35° C to
66°C) when used with a Weatherproof Back Box (Model WBB) as
tested by UL. In Canada, rigid steel conduit must be used when
installing the Weatherproof Back Box. The light output of the
SS12LO, SS24LO, MASS12LO and MASS24LO is 1.5 cd min
@100% viewing angle. The light output of the SS24M, MASS12M,
and MASS24M is 15 cd min @100% viewing angle (See Figure 3).
There are eight different sounds which can be selected on the
electronic sounder by adding or removing tab clips (see Figure 4).
The sound selected will determine the maximum current and
sound power output per device. See Table 2 for these values.
