Appleton's Code-Master's explosion-proof strobe and beacon lighting fixtures are designed to warn occupants of unsafe working conditions, and are especially effective in areas where audible signals cannot be heard. The strobe flashes 65 times per minute; the beacon fixture rotates 75 times per minute. Clear, amber-, blue-, green- or red-tinted globes are available and there is an optional fire alarm strobe for the hearing impaired. http://www.appletonelec.com/ DIRECT Info #403
