Euro Stopper Multi Kit Surface Mount with Integral Sounder Red - 

Protective cover helps prevent malicious or accidental false fire alarms. Sleeker and less intrusive in its design, this compact device incorporates the existing features of the Stopper® but is now visibly smaller. The hinge arrangement increases the durability, strength and quality of this essential protective cover. Ideal for schools, colleges, hospitals, nursing homes, hotels and all public buildings where there is a history or a threat of false fire alarms.
