POTTER SC/SSC25/70-3075110 Select-A-Strobe Speaker Combination

INSTALLATION

ADA/NFPA/ANSI compliant
Screw terminal capacity up to AWG #12
RBX-1 back box skirt for surface mount (optional)
Available in red or white housing
All models mount to 4” back box
Speaker is UL 1480 listed for ﬁ re protective service
Speaker ﬁ eld selectable wattage from ¼, ½, 1, and 2 Watts
Speaker is available in 25V RMS or 70.7V RMS models
Speaker frequency range 400 to 4000 Hz
Strobe is UL listed for ceiling and wall mount
Strobe has three ﬁ eld selectable settings: 30,75, or 110cd
Polarized strobe is operable with 24V regulated DC or FWR (16-33V)
Synchronization requires SMD10-3A Sync Module

Amseco’s ceiling and wall mount ﬁ re alarm Select-A-Strobe/Speaker 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 unique candela intensity ﬁ eld selector switch for alternating the candela ouput to 30cd, 75cd, or 110cd, 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 SSC25-3075110 or SSC70-3075110 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 accordance with current NFPA guidelines.
