This Horn/Strobe/Speaker Damage Stopper protects a System Sensor unit against vandalism and accidental damage. Wire guard provides maximum protection to this speaker/strobe notification appliance. One of the newest members of the STI Wire Guard Team, this protector was created in response to multiple requests from STI customers. It consists of a tough, 9-gauge steel wire that is coated with corrosion resistant white polyester, which offers excellent protection. Installation is fast and simple with the screws and anchors provided. This guard is designed to fit over System Sensor SP2R1224MC and SP2W1224MC. STI guarantees the guard for a three year against breakage in normal use.
