Compatible with most conventional fire alarm systems, the Waterproof 'ReSet' is a unique manual call point that simulates break glass activation while offering the user the benefits of a re-settable operating element. An activation indicator drops into view on activation. The unit is then simply reset with a key and is ready for immediate re-use. See Label Options below for 'Standard Function Marking' information on the Waterproof ReSet product. Dimensions: 3.54in H x 3.50in W x 2.83in D ***Special Order***
