Gri 100-TC-B Surface Contact with Cover Brown

Product Description

The George Risk Industries 100-TC-B is a surface-mount contact designed for door and window security sensing applications. It ships as a single unit with a protective cover included, finished in brown to blend with wood-tone frames and trim. Surface contacts in this class are staples of alarm and access-control installations, providing the normally open or normally closed circuit signal that panels and controllers rely on to detect open or closed status. Alarm technicians and low-voltage security installers are the primary trades working with this component.

The 100-TC-B fits typical residential and light commercial security installations where surface mounting is preferred over recessed routing. The cover protects the contact body and wiring termination, making it well suited for finished interior trim where exposed hardware must be kept neat. It is commonly installed on hinged doors, sliding windows, and casement frames where flush recessed magnets are not practical.

Key Features

• Surface-mount design allows installation without routing or boring into the frame
• Included cover protects the contact body and terminal connections
• Brown finish blends with wood-tone door and window trim
• Single-unit packaging for per-point ordering flexibility
• Part of the 100 Series line, consistent with established GRI form factors

Compatibility

Designed as an OEM-style surface contact for residential and light commercial security and access-control systems requiring a standard surface-mount door or window sensing point.

Installation Notes

Installation is typically performed by licensed low-voltage or alarm technicians in compliance with applicable local codes and NFPA 72 where required. Power down or disarm the security panel before wiring the contact to avoid triggering false alarms or damaging panel inputs. Mount the contact body and magnet on opposing surfaces so the gap between them falls within the manufacturer-specified operating range noted on the product data sheet. Secure wiring leads to prevent strain on the terminal connections after the cover is fastened.
