Overview

Designed for dependable security monitoring on steel doors, the George Risk Industries GRI 8484-T-B recessed switch set delivers tamper-resistant intrusion detection for access control and alarm systems. This 1 in recessed magnetic contact (standard 0.5 in gap) provides a closed-loop normally open (N/O) contact that supports up to 0.40 A at 160VDC, making it ideal for low-voltage security, surveillance and building monitoring circuits. Its solid steel, one-piece construction sits flush in the door or frame for a discreet appearance and added vandal resistance.

Installers appreciate the self-lock mounting and screw-terminal termination that speed commercial installations and reduce labor costs versus soldered leads. UL/ULC approval and a lifetime warranty help ensure code compliance and long-term reliability for high-traffic doors. Use the GRI 8484-T-B in access control, alarm panels, or perimeter monitoring to maintain continuous, accurate status reporting. Order this rugged recessed magnetic contact for your next security or surveillance project to improve system reliability and simplify installation.
