OC55 Rolling Door and Gate Wired Magnetic Reed Switch Alarm Sensor with Screws, NO/NC Short summary A wired magnetic reed switch designed for door, gate, and rolling shutter security. The OC55 provides a reliable open and closed contact that connects directly to most wired alarm control panels. Mounting screws are included for fast installation. Key benefits Simple intrusion detection: Detects when a door, gate, or shutter opens or closes and triggers your wired alarm system. Flexible wiring: Supports normally open and normally closed configurations to match a wide range of alarm panels and installation preferences. Fast to install: Compact twopart sensor plus magnet mounts with included screws for quick setup on frames, doors, or rolling shutters. Practical and dependable: Provides a direct wired contact signal for stable, continuous monitoring without pairing or batteries. What it does and how it solves problems Provides immediate, hardwarelevel detection of open and closed states for doors and gates, removing ambiguity from zone monitoring. Eliminates the need for wireless pairing or battery changes by using a wired contact that ties directly into existing alarm wiring. Offers both NO and NC options so you can maintain fault detection and tamper resistance required by many alarm systems. Key attributes Function: Magnetic reed switch that changes contact state when the magnet and sensor are separated or aligned. Compatibility: Designed for rolling doors, garage doors, gates, shutters, sliding doors, and windows; compatible with standard wired alarm control panels that accept reed switch inputs. Wiring: Supports normally open and normally closed wiring arrangements for integration with different alarm panel configurations. Hardware: Supplied with mounting screws for secure attachment; sensor and magnet come as a twopiece set for surface mounting. Size and installation: Compact footprint suited for tight mounting locations on frames and shutters; ideal when hidden or lowprofile installation is needed. Performance: Provides direct wired contact signaling for consistent detection of open and closed conditions. Typical applications Residential garage door: Connect the sensor to your home alarm panel to alert when the garage door is opened or left ajar. Commercial rolling shutter: Monitor rollup doors and integrate into an alarm system to detect unauthorized openings after hours. Gate or sliding door: Use on gates or sliding doors to add a wired contact zone for perimeter security or access monitoring. What is included OC55 magnetic reed switch sensor and magnet Mounting screws for straightforward installation Wiring leads for connection to a wired alarm system (supports NO and NC) Installation tips Mount the sensor and magnet so they align when the door or gate is closed, with a small separation margin recommended by your alarm panel instructions. Choose NO or NC wiring based on the alarm panel requirement and to support fault or tamper monitoring. Test the circuit after installation to ensure the alarm panel correctly registers open and closed states. The OC55 wired magnetic reed switch is a practical component for any wired alarm setup where direct, reliable door or gate status detection is required.
