Seco-Larm Enforcer Overhead Door Magnetic Contact, Closed Loop (SM-226RQ)

The Seco-Larm Enforcer Overhead Door-Mount Magnetic Contact, Closed Loop is a contact switch designed for large doors and gates where regular contacts may be difficult to mount. The contact's large gap allows use with even the largest doors, such as garage doors. The switch is contained in low-profile cast aluminum housing, and curved so that heavy vehicles can cross over without damaging it.Closed loop contact switchUse on large doors or gatesMagnet enclosed in round bracket24-inch wire leads enclosed in stainless-steel cableRugged, Long-Lasting ConstructionSeco-Larm contacts have a unique rhodium plating which has gone through a special oxygen treatment to deactivate the surface, thus eliminating the absorption of organic impurities, polymer growth during operation, and the possibility of contact freezing.The switch is housed in weatherproof die-cast aluminum constructed for surface-mounting on a garage floor. It can withstand heavy vehicle pressure without damage. The switch is safely enclosed in an epoxy compound, and a 24-inch flexible stainless-steel cable gives complete protection to the switch wiring.The magnet is enclosed in an epoxy compound inside a round-backed aluminum housing, which mounts directly to the garage door. Its special shape discourages using the housing as a foothold when closing the door, and offers no projecting edges to catch when the door is raised.Technical DetailsManufacturer Part #: SM-226RQUPC: 676544006480Alarm circuit: Three-wire N.O./N.C.
