George Risk Industries 2020 3/8 in. Recessed Closed-Loop Contact

Add recessed opening protection to a hardwired security circuit with a compact magnetic contact installed within the door, window, frame, or adjacent trim. The 3/8 in. format keeps the sensing hardware less visible than a surface-mounted contact while supporting a closed-loop circuit arrangement. Terminal connections provide a direct point for attaching field wiring rather than relying on a pre-attached lead. George Risk Industries 2020-T-B fits installations where the protected opening and its frame can accept a recessed contact body. Closed-loop operation supports monitored perimeter zones commonly used for exterior doors, accessible windows, cabinets, and other openings that need to report a change in position to an alarm panel. The terminal termination style is useful where installers need to route, land, and service conductors at the contact location. Within the 2020 contact range, this configuration combines the 3/8 in. recessed format, closed-loop circuit type, and terminal connection method. The B suffix identifies the brown version, allowing the contact to better match brown mounting surfaces. Select the contact type, circuit arrangement, mounting depth, and mating alignment requirements to match the protected opening and the alarm system input before installation.
