Wired shutter roller magnetic overhead door contact, normally closed type, with mounting bracket Overview This wired magnetic contact is designed to monitor roller shutters and overhead doors. The normally closed (NC) reed switch provides a clear open and closed signal for alarm systems, access control panels, or door controllers. A supplied mounting bracket simplifies installation on shutter boxes and door frames. Key benefits Reliable door position detection: NC output gives a stable closedcircuit signal when the door is in the closed position and opens the circuit when the door moves, reducing false triggers. Simple integration: Wired connection and standard contact behavior make it compatible with most alarm panels and access control systems that accept door contacts. Easy installation: Supplied mounting bracket allows secure attachment to roller shutter housings and overhead door frames without complex modifications. Low maintenance: Solidstate reed switch design delivers dependable operation through repeated cycles with minimal upkeep. What it does Detects the open or closed state of roller shutters and overhead doors using a magnetic reed switch. Outputs a normally closed contact signal suitable for security systems and door control logic. Mounting bracket positions the sensor and magnet for consistent alignment and reliable switching. Compatibility and applications Works with alarm panels, access control systems, door controllers, and monitoring devices that support NC door contacts. Intended for roller shutter doors, overhead doors, sectional doors, and similar sliding or rolling door systems. Suitable for residential garages, retail storefront shutters, and industrial warehouse doors. Key attributes Function: Magnetic reed contact for door position detection. Contact type: Normally closed (NC). Connection: Wired contact for direct integration with control systems. Mounting: Includes bracket for fixed mounting and alignment. Performance: Designed for consistent switching and repeated operation on roller and overhead doors. Typical use scenarios 1) Retail storefront: Install on a roller shutter to send a closed signal to the alarm system when the shutter is down and automatically generate an alarm or notification if the shutter opens outside scheduled hours. 2) Residential garage: Integrate with a home security or automation system so the garage door position is monitored and logged, enabling remote alerts or automation based on door state. 3) Warehouse overhead door: Monitor large overhead doors for access control and record door activity for operational tracking or security audits. Installation notes Mount the sensor and magnet with the included bracket so that the magnet aligns with the reed switch when the door is closed. Connect the wired contacts to the NC terminals on the alarm panel or control device following the system wiring diagram. Verify alignment and correct NC behavior during initial setup to ensure reliable operation.
