Description

The bell/strobe adapter plates come equipped with an electronic strobe signal and has provisions for mounting a fire alarm bell (not supplied). The units are intended for indoor use only with compatible fire protective signaling systems. The strobes are self-synchronized to flash at 1 fps across their full operating voltage range. Studies show that people with photosensitive conditions may experience a photoconvulsive response from multiple random flashes of light. This risk is minimized with these strobes. The strobe operates on any existing 2- wire signal circuit. Separately installed “sync control modules” are not required. The bell/strobe adapter plate is to be installed in accordance with the latest edition of NFPA 72, National Fire Alarm Code. It is recommended that these products be installed in accordance with the requirements in the latest recognized edition of national and local fire alarm and electrical codes. Synchronization of less than 200 milliseconds will be maintained for no less than 60 hours supervision followed by 30 minutes in alarm. See Table 1 and Figures 1, 3 and 4 for specifications.
