STI’s Horn/Strobe/Speaker Damage Stoppers are UL/cUL listed guards designed to protect System Sensor SpectrAlert Advanced series of notification appliances. Constructed with 9-gauge steel wire, coated with corrosion-resistant red or white polyester, they are tough against accidental or intentional damage. They are available in flush- or surface-mount models. Guards are recommended for areas where abuse is severe or it is imperative horn/strobe/speakers continue to operate. Installation is fast and simple with the screws and anchors provided. STI guarantees the guards for three years against breakage in normal use. A variety of wire cages are available for smoke detectors, emergency lights, speaker/strobes, clocks, and more.
