Introduction

The Cerberus Pyrotronics F-Series of horns and hornstrobes combines high quality electronics with the rugged durability of a metal housing, providing the penetrating sound power of an electromechanical horn while eliminating the inrush and RFI noise problems associated with mechanical signals. These units are designed for ADA applications and meet the latest requirements of NFPA 72 (the National Fire Alarm Code) and UL 1971 standards for signaling devices for the hearing impaired.

Description

The eight distinct sounds (HORN, TEMPORAL, BELL, HI-LO, CHIME, SIREN, SLOW WHOOP, SINGLE STROKE BELL) are field selectable. The energy efficient horn design draws only 16 to 40 mA while supplying up to 101 dB at 10 feet, depending on tone selected. Screw terminals are provided for both the horn and strobe and can be configured to operate together or independently. Units are available for flush, surface, or ceiling installation.
All strobe versions utilize a Xenon flashtube with solid state circuitry for maximum reliability and efficiency. Strobes are available in 15, 15/75, 75 and 110 Candela ratings with various mounting configurations. The top of the strobe has a rounded dome shape made of clear Lexan®. The overall lens height is 2.5” with a width of 1.25”.
The S15 model provides 15 cd and are used in nonsleeping areas where lower candela is required per UL 1971.
The S17 model is for non-sleeping installations requiring 15 cd output while also providing an ADA compliant 75 cd frontal output for public areas.
The S75 version offers a 75 cd polar output that meets ADA requirements for regular lighted public areas while also satisfying UL 1971 in substitution of multiple 15 cd units.
The S110 version intensifies a non-sleeping ADA area with 110 cd and can be used in sleeping areas to help wake the hearing impaired person per UL 1971.
