<br />Mounting and Installation <br /> <br />2M detector bases mount directly to standard single-gang <br />electrical boxes, three-inch round, orfour-inch octagonal boxes. <br />Detector heads simply twist onto the base. Heads are equipped <br />with a break-away locking tab, which prevents unauthorized <br />removal. Terminals accept 12 to 24 AWe field wiring. <br /> <br />Dimensions <br /> <br />17_."..' <br />/'/.>0/..._....., '.
