The TANE ALARM sm-35gr is a surface mount magnetic contact designed for security alarm and access control installations. The wide gap design allows for reliable door and window sensing even when slight misalignment or thicker frame materials are present. Supplied in a gray finish to blend with standard residential and light commercial trim, the sm-35gr ships in a 10-pack, making it a practical choice for technicians wiring multiple openings in a single job. Alarm installers and low-voltage security contractors are the primary trade handling this component.
The sm-35gr is suited for surface mount applications on inward- or outward-swinging doors, sliding windows, and casement windows where recessed mounting is not practical. The wide gap tolerance reduces callback risk in situations where door frames flex or settle over time. The gray color coordinates with painted wood, vinyl, and aluminum frames common in residential alarm work and light commercial retrofits.
Designed as an OEM-style replacement or new-install surface mount magnetic contact for standard residential and light commercial alarm and access control systems.
Installation is performed by licensed low-voltage or alarm system technicians following local security licensing requirements and applicable electrical codes. Power down or disarm the alarm panel before wiring contacts to avoid triggering tamper or fault conditions. Secure the magnet to the moving sash or door and mount the switch body to the fixed frame, maintaining the gap distance specified by the panel manufacturer. Avoid mounting on highly ferrous metal surfaces that may interfere with magnetic field performance.
