This Universal Stopper® with Horn, Flush Mount, Fire Label (STI-13020FR) has been helping to prevent false fire alarms around the world for over 40 years, without restricting legitimate alarms. The strong, durable construction takes the toughest knocks while it guards against accidental or intentional physical damage.

Consists of a clear, tamperproof, super tough polycarbonate cover, piezo horn, and frame that is designed for flush mount manual pull stations. When lifted to gain access to the protected unit, a piercing 105 dB battery-powered warning horn sounds. Immediate attention is drawn to the area and a prankster will either run or be caught.
