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 MA12/24EH is suitable for connection to either
a 12 or 24 volt panel. Models SS24LO, SS24M, MAEH24LO and
MAEH24M require 24 volt panels; models SS12LO, SS12M,

Table 2. Sound output and current ratings for the MA12/24EH:
Table 1. SS12/24 electrical and light ratings:
Note 4: See Figure 4 for tab clip removal & storage.
Note 5: All horn or combination strobe models can be powered
using full wave rectified unfiltered supplies.
Under no circumstances can the
input voltage:
for the SS24 or MAEH24 exceed
33 VDC or be less than 18 VDC.
for the SS12 or MAEH12 ex-
ceed 18.7 VDC or be less than
9.6 VDC.
for the MA12/24EH exceed 33
VDC or be less than 9.6 VDC.
Note 1: With 1.5 cd strobes add 50 mA @ 12V, 25 mA @ 24V.
With 15 cd strobes add 180 mA @ 12V, 75 mA @ 24V.
Note 2: Sound output measured in anechoic room at 10 feet.
Note 3: Sound output measured in UL reverberant room.
MAEH12LO and MAEH12M require 12 volt panels. Horn, strobe,
or combination strobe models may be used with panels that have
full wave rectified, unfiltered supplies. The MA12/24EH sounder
and MAEH12/24 sounder/strobes are suitable for outdoor appli-
cations (–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. Light
output for the SS12LO, SS24LO, MAEH12LO and MAEH24LO is
1.5 cd min @100% viewing angle. Light output for the SS12M,
SS24M, MAEH12M, and MAEH24M 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.
