and horn strobes in the industry. With white and red plastic housings, wall and ceiling mounting options, and plain and FIRE-printed devices, Spectralert Advance can meet virtually any application requirement.
The wall-mount horns, strobes, and horn strobes include a variety of features that increase their application
versatility while simplifying installation. All devices feature plug-in designs with minimal intrusion into the
back box, making installations fast and foolproof while virtually eliminating costly and time-consuming ground
faults.
The temporal tone generated by the horn portion is designed as per ANSI and NFPA72 for standard emergency
evacuation signaling requirement. The horn has the feature that can synchronize multiple horns in a complete
fire alarm system.
