Amseco’s high quality fi re alarm speakers are designed to generate attention
grabbing tones and voice commands for emergency signaling evacuation
applications. These highly effi cient speakers are available with fi eld
selectable taps from 2 – 8 Watts. The speakers are available in two input
voltage models, 25V RMS and 70.7V RMS and can be installed on a standard 4”
electrical back box with an extension ring. The SFH45-153075 Series features a
new and exclusive select-a-strobe. The strobe utilized a unique candela
intensity fi eld selector switch for alternating the candela output from 15 to
30. The strobe housing is clearly labeled with “FIRE” lettering and is
polarized for connecting to supervised fi re alarm circuits. The strobe is
designed with a xenon fl ash tube and provides a candela intensity fi eld
selector switch for maximum performance. They are available in red or white
housing.
The strobe can be synchronized by using the SMD10-3A Sync Module to comply
with NFPA recommendations concerning photosensitive epilepsy when installing
two or more visual appliances within the fi eld of view. The strobe signals
are listed for indoor use, ceiling and wall mount, under UL 1971 Standard.

Engineering Specifi cations
The fi re alarm speaker shall be capable of reproducing alarm tones or voice
commands on 25V RMS or 70.7V RMS. Speakers shall provide incremental tap
settings of 2, 4, or 8 Watts and shall be selected by means of a jumper wire.
The speaker shall have a frequency range of 400 – 4000 Hz and shall have an
operating temperature between 14°F and 140°F. The speaker shall produce a UL
sound pressure level at 10 feet up to 84dB. The speaker shall be approved for
fi re alarm signaling use. The strobe shall be listed under UL 1971 standard
for signaling devices for the hearing impaired and shall be approved for fi re
protective service. The candela ouput shall be fi eld selectable, having a
dual setting of 15/75cd or 30/120cd output. The signaling strobe shall operate
on 24V DC from a non-coded regulated DC supply or full-wave rectifi ed, unfi
ltered supply. It shall be designed to produce one signal fl ash per second
with continuously applied minimim voltage. The SFH45-153075 shall be capable
of wall or ceiling mounting. The visual signaling devices are to be installed
in all non-sleeping/corridor areas as per plans and specifi cations.
