Owner’s Manual
Application
The Potter FEP and SEP Series is an indoor wall mount expander plate with a quality colored lens strobe to be used in conjunction with a Potter speaker or wall mount speaker/strobe allowing the ability to mount multiple strobes on a single electrical box. Applications include emergency communication, severe weather, evacuation, emergency response and many more.
Description
The FEP Series is to be used in flush mount applications and the SEP Series is to be used in surface mount applications. The FEP and SEP Series strobes are to be used on a 24 VDC system and are available in amber, blue, green, and red lens colors. The amber lens units are provided with a turn dial for field selectable candela options. The blue, green and red lens units are only available in 15/75 candela option. The strobes can be synchronized using the Potter AVSM, FACP’s or power supplies that provide a Gentex Synchronization Protocol. All units feature ALERT text on the lens.
The FEP and SEP Series are constructed of high impact textured plastic. The amber lens units additionally comply with the light output dispersion requirement of ANSI/UL 1971 for wall mount applications with a measured candela rating that is equal to the candela listed on the product.
