Seco-Larm SM-200Q/BR Low-Profile Surface-Mount Magnetic Alarm Sensor (Pack of 5)

The Seco-Larm SM-200Q/BR is a surface-mount, closed-loop, low-profile magnetic contact designed for commercial and professional life-safety and security installations. As a genuine Seco-Larm product, it is engineered to integrate reliably into intrusion detection systems where a discreet, low-profile form factor is required. Surface-mount installation simplifies deployment on doors and windows without the need for recessed routing, making it well suited for retrofit projects and new construction alike. The closed-loop circuit design provides a fail-safe supervisory signal, alerting the control panel immediately upon any interruption of the magnetic field.

Key features & benefits

• Surface-Mount Design — Installs directly onto door or window frames without recessing, enabling straightforward deployment across a wide range of entry points and materials.
• Low-Profile Form Factor — The compact, low-profile housing minimizes visual impact on the protected opening while maintaining reliable detection performance in professional security environments.
• Closed-Loop Circuit — Operates on a normally closed supervisory loop, ensuring that any separation of the magnet from the contact triggers an immediate alarm condition at the connected control panel.
• Genuine Seco-Larm Component — Manufactured by Seco-Larm, a recognized name in commercial security hardware, providing confidence in build quality and consistency for professional integrators and installers.
