Tane Alarm sm-21wg-wh Surface Mount Contact White

Product Description

The TANE ALARM sm-21wg-wh is a commercial-grade surface mount door contact designed for open-loop alarm circuit applications. Built for use on commercial and steel door installations, this contact provides reliable magnetic detection at the door frame without requiring flush mounting or cutouts. Licensed alarm installers and low-voltage technicians are the primary trade installing this device as part of intrusion detection or access control systems.

This contact is suited for commercial facilities where surface mounting is preferred or required by door construction. It performs well on steel doors, which are common in commercial entry points, stairwells, storage areas, and server rooms. The open-loop wiring configuration makes it straightforward to integrate into standard alarm control panel zones.

Key Features

• Commercial-grade surface mount design requires no door cutout or flush installation
• Compatible with steel door applications where embedded contacts are not practical
• Open-loop circuit configuration for standard alarm zone wiring
• White finish for clean appearance on light-colored door frames
• Low-profile form factor suitable for commercial door hardware environments

Compatibility

Designed as an OEM-style surface mount contact for commercial door alarm and access control systems, particularly suited for steel door applications.

Installation Notes

Installation is performed by licensed low-voltage alarm technicians following local codes and NEC low-voltage wiring requirements. Power down the alarm control panel zone before connecting wiring to avoid false triggers or panel faults. Mount the contact body to the door frame and the magnet to the door leaf, ensuring proper gap alignment per the manufacturer specification. Do not install on ferrous metal surfaces that may interfere with the magnetic field unless the product is specifically rated for steel door use, which this unit is.
