GRI VSB-08-W Vent Switch, 1/2" Air Gap, Open Loop, Reed Form, 5W, White

Designed for installers and homeowners who need secure ventilation without compromise, the George Risk Industries VSB-08-W Vent Switch is a purpose-built magnetic contact that preserves perimeter security while allowing a window to be opened several inches. This reed-form magnetic contact maintains a closed circuit through up to approximately 8" of linear travel based on a standard 1/2" air gap, enabling slider and double-hung windows to be vented while the system remains armed. The VSB-08-W reduces false alarms and 'owner-induced' trips by eliminating the need to disarm for normal window operation, improving everyday usability for monitored sites. Built for professional security and surveillance installations, the surface-mount design, wired connectivity, and standard 36" zipcord lead make integration into alarm panels straightforward. UL/ULC approvals and a lifetime limited warranty give installers and end users confidence in long-term performance. Ideal for residential and commercial perimeter security applications where controlled ventilation is required—specify the GRI VSB-08-W for reliable window monitoring and simplified installation.
