Federal Signal Models FSF200ST and FSF201ST Combination Selectable Strobe and Horns are designed to provide both visual and local audible indication indoors when activated by a Fire Alarm Control Panel. Each model can be synchronized to work simultaneously with other units and each complies with NFPA requirements and UL categories 464 and 1971 for private mode fire applications.
The model FSF200ST and FSF201ST Combination Selectable Strobe and Horn provides two different field selectable Strobe outputs and two different audible tones. Each model contains a front mounted tamper–proof switch that allows the user to select the amount of strobe light flash energy required for the application. The FSF200ST is capable of either 15 or 30 Candela and the FSF201ST is capable of 75 or 110 Candela. There are also two different tone settings, with each tone having a high or low output setting. A 3000 Hz tone or simulated electromechanical tone can be selected by configuring mini jumpers located on the back of the unit. A temporal or non–temporal Tone Pattern and a high or low dB output are selected in the same manner.
Each model is molded in red and clearly labeled with white FIRE lettering, while polarization is standard for connecting to supervised fire alarm circuits. The FSF200ST and the FSF201ST are available in 24VDC only, however, each will operate with a regulated DC supply or a FWR (full wave rectified) power source. Both the FSF200ST and the FSF201ST are listed for wall mounted indoor use, under the UL1971 standard.
The FSF200ST and FSF201ST can be connected either independently or in unison. Using the FSF206 Synchronization module, both audible and visual patterns can be synchronized if two or more audible appliances are desired.
Each FSF Combination Strobe and Horn incorporates a slim profile, designed to be unobtrusive and minimize potential obstruction. The included mounting plate is designed to fit a 4 square junction box, 3 1/4 octagon box or plaster ring and it adapts easily to uneven mounting surfaces.
