The 2GIG DW30-345 eSeries Encrypted Outdoor Wireless Contact Sensor is engineered to provide robust and secure perimeter protection for challenging outdoor environments, including gates, sheds, doors, and windows. It features 128-Bit eSeries encryption, ensuring that signals sent to compatible 2GIG eSeries panels (GC2e, GC3e, Edge) are protected against tampering and unauthorized interception. Built to withstand extreme conditions, the DW30-345 boasts an IP56-rated weatherproof housing that is also paintable to match its surroundings. It operates reliably in temperatures ranging from -40°F to 150°F. This versatile sensor offers dual-zone protection with an internal magnetic reed switch and a normally closed (NC) external circuit for integrating an additional wired sensor. A wide 2'' magnet gap accommodates various installation scenarios, including oversized openings. With an open-air signal range of up to 350' and a long 5-year battery life from its CR123A lithium battery, the DW30-345 minimizes maintenance. It is fully supervised, providing real-time notifications to the alarm panel. This sensor is backed by a two-year limited warranty, offering peace of mind and professional-grade security.
