This plastic door magnet sensor provides discreet, lowprofile detection and is supplied in a brown finish to better blend with wood doors and frames. Key benefits Reliable entry detection: The normally closed (NC) magnetic switch keeps the circuit closed when the door or window is shut and opens the circuit when separated, allowing alarm hosts to detect unauthorized openings. Discreet appearance: Brown plastic housing minimizes visual impact on wooden doors and frames while remaining practical for many interior installations. Simple wired mounting: Designed for wired installation with alarm panels and accessory inputs, giving stable, interference connections for security systems. Main features and attributes Functionality: Magnetic reed switch that changes state as the magnet and switch move apart; normally closed (NC) configuration. Compatibility: Intended for use as an alarm host accessory with wired security panels and detectors that accept NC magnetic contacts. Material and finish: Durable plastic housing in brown. Mounting: Wired mounting format for secure installation on doors, windows, or frames; typically used as a pair (magnet + switch). Performance: Provides dependable open/close detection when correctly aligned and wired to an alarm host. Operation details Normally closed (NC): The switch circuit is closed (conducting) when the magnet is adjacent to the switch. When the door or window opens and the magnet separates from the switch, the circuit opens and the alarm host is alerted. Wiring: Intended for wired connection to the alarm host or control panel input for door/window monitoring. Typical applications Home security: Mount on interior or exterior doors to monitor entry and trigger alarms when doors are opened. Window protection: Install on sliding or casement windows to detect opening and protect groundlevel access points. Commercial or retail premises: Use with alarm panels to secure back rooms, display cases, or service entrances where a discreet brown sensor is preferred. What to consider when installing Confirm your alarm host or control panel accepts normally closed wired contacts before installation. Position the magnet and switch so they align when the door or window is closed to ensure reliable operation. Use appropriate wiring practices and secure connections to maintain consistent signal integrity. This brown, normally closed plastic door/window magnet switch is a straightforward, effective accessory for wired alarm hosts where discreet, dependable open/close detection is required.
