Specifications
– Siemens Series ‘SEFH’ High-Fidelity speaker appliances are Siemens Series ‘SEFH’ HiFi Speakers, and the
HiFi speaker-strobe appliances are Siemens Series ‘SEFH’ HiFi Speaker Strobes or approved equals
– HiFi speakers are UL Listed under Standard 1480 for Fire Protective Service, and speakers equipped with
strobes are listed under UL Standard 1971 for Emergency Devices for the Hearing-Impaired
– Siemens Series ‘SEFH’ HiFi speakers are designed for a field-selectable input of either 25 or 70 VRMS, and
with field-selectable power taps from 1/8 Watt to 2 Watts
– Selector switch, which is used to manually selecting the candela setting, is tamper-resistant by design
– Siemens Series ‘SEFH’ HiFi models have listed sound outputs of up to 87dBA at 10 feet,
and a listed frequency response of 300 to 8000 Hz
– Speaker appliances feature sealed-back construction for optimum audibility
– All inputs employ terminals that accept
#
12 to
#
18 AWG wire sizes
– Strobe intensity, where HiFi Candela appliances are specified, have field-selectable settings, and are
rated, per UL Standard 1971 for Emergency Devices and for the Hearing-Impaired, for the following:
▪ 15/30/75/110cd (wall mount, single-Candela strobes) -or-
▪ 135/185cd (wall mount, multi-Candela strobes)
▪ 15/30/75/95cd (ceiling mount, single-Candela strobes) -or-
▪ 115/177cd (ceiling mount, multi-Candela strobes)
– Strobe portion of each HiFi appliance produces a flash rate of one (1) flash per second,
and incorporates a Xenon flashtube enclosed in a rugged Lexan® lens
– Strobes are of low-current design
– When synchronization is required, the strobes portion of Siemens Series
‘SEFH’ appliances is synchronized using the following:
▪ Siemens Dual-Sync Control Modules -> Model DSC-series with built-in sync protocol
▪ Siemens 252 / 504-point addressable fire-safety systems
▪ Siemens Modular systems and FireFinder® XLS control panels
▪ The Siemens PAD-series of NAC Extenders
– Siemens Series ‘SEFH’ meets the requirement for low-frequency signal tone [as described in the section
for Determination of Low Frequency Signal Format in the Standard for Audible Signal Appliances, per UL464] when used with:
▪ One (1) Amplifier Card {Model VCI2001-U1} with Siemens 252-point / 504-point addressable FACPs
▪ One (1) Booster Amplifier {Model EBA200x Series} with Siemens 252-point / 504-point addressable FACPs
▪ One (1) 40W Zone Amplifier Card {Model ZAC-40} with Siemens Modular systems and FireFinder XLSV
– The strobes will not drift out of synchronization at any time during operation
– Siemens ‘SEFH’ Series strobes revert to a non-synchronized flash-rate, if the dual-sync module or the
Siemens PAD-series NAC Extenders should fail to operate (i.e. – contacts remain closed)
– HiFi ceiling speakers and speaker-strobe appliances are designed for indoor-surface or flush mounting
– HiFi speakers and speaker-strobes incorporate a speaker-mounting plate
with a grille cover, which is secured with two (2) screws for a level finish
▪ Grille cover mounts to standard electrical hardware requiring no additional trim plate or adapter
– Series ‘SEFH’ HiFi speakers and speakers strobes are available for ordering in either white or red
– All speaker and speaker-strobe appliances are listed for Special Applications:
▪ Strobes are designed to flash at 1-flash-per-second minimum over their “Regulated Input Voltage Range”
➢ Note: NFPA-72 specifies a flash rate of 1-to-2 flashes per second, and ADA Guidelines specify
a flash rate of 1-to-3 flashes per second
▪ All candela ratings represent minimum-effective Strobe intensity, based on UL Standard 1971
