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.
