TrueAlert non-addressable free-run strobes provide quick and convenient installation using a flexible mounting design. The strobe housing is a rugged, one-piece assembly (including lens) that mounts to single gang, double gang, or 4” square standard electrical box. Wiring terminals are accessible from the front of the housing, providing easy access for installation, inspection, and testing. The cover can be quickly removed (a tool is required) and when in place, the entire assembly is impact and vandal resistant. Separate covers are available for color conversion.
