This unique device has been helping stop false fire alarms around the world for decades, without restricting legitimate operation of devices such as access controls, digital keypads, smaller manual pull stations, shutdown switches in computer rooms, workshops and many more. The Mini Stopper II offers excellent protection against physical damage both accidental and intentional, dust and grime as well as severe environments inside and out. The Mini Stopper II consists of a clear, tough polycarbonate cover, frame that fits over the protected unit and conduit spacer. When lifted to gain access to the protected unit, its optional battery powered alarm emits a piercing 105 dB. Immediate attention is drawn to the area and a prankster will either run or be caught. With optional gaskets, Mini Stopper II can dramatically extend the life of equipment mounted in saltwater areas.
