The enclosure designs are both impact and vandal resistant <br />and provide a convenient strobe intensity selection. You can select <br />each model for strobe intensity output. This minimizes on -site model <br />inventory and easily accommodates changes encountered during <br />construction. <br />Wall mount <br />SN housings are a one-piece assembly, including lens, that mounts to <br />a 4 in. square electrical box with extension, see Wall mount installation <br />reference. You can quickly remove the cover with a tool and covers are <br />available separately for color conversion. <br />Ceiling mount <br />S/Vs also install using 4 in. electrical boxes with an extension. See Ceiling <br />mount SN installation reference and 2905-9946 tile bridge dimensions. <br />Strobe intensity selection <br />During installation, a selection plug at the back of the housing <br />determines the desired strobe intensity. An attached flag with black <br />letters on a highly visible yellow background allows the selected intensity <br />to be seen at the side of the strobe lens. <br />S4906-0003 Rev. 11 4/2021 <br />
