Amseco’s ceiling and wall mount ﬁ re alarm Speaker/Strobe Series are designed to generate attention grabbing tones and voice commands for emergency signaling evacuation applications. These highly efﬁ cient, low proﬁ le speakers are available with ﬁ eld selectable taps ¼, ½, 1, and 2 Watts. The speakers are available in two input voltage models, 25V RMS and 70.7V RMS and can be installed on a standard 4” square back box. The strobe features a candela output of 177cd, and is polarized for connecting to supervise ﬁ re alarm circuits. The strobe housing is clearly labeled with “FIRE” lettering and is designed with a xenon ﬂ ash tube and provides a candela intensity ﬁ eld selector switch for maximum performance. The series can be synchronized by using the SMD10-3A (daisy chain) 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 designed for non-sleeping areas and are listed for indoor use.

Engineering Speciﬁ cations

The speaker and visual alarm indicating appliance shall be Amseco Model SSC25-177 or SSC70-177 or equivalent device. The speaker shall be listed under UL 1480 standards for audible and voice communications and shall be approved for ﬁ re protective service. 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 ¼, ½, 1, or 2 Watts. They shall have a frequency range of 400 to 4000 Hz and produce UL sound pressure level at 10 feet up to 84dBA. 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 protection service. The candela ouput shall be ﬁ eld selectable, having three settings of 30cd, 75cd, or 110cd. The signaling strobe shall operate on 24V DC from a non-coded, regulated DC supply or full-wave rectiﬁ ed, unﬁ ltered supply. The strobe shall be designed to produce one signal ﬂ ash per second with continuously applied minimum voltage. The strobe may have a SPC-1 universal back mounting plate, capable of ceiling or wall mounting to a back box. When strobe synchronization is required, the strobe shall be compatible with the Amseco SMD10-3A (daisy chain) or other source of Amseco sync protocol. Signaling devices shall be installed in sleeping areas in accordance with current NFPA guidelines.
