The 2GIG 2GIG-DW100-345 345MHz Wireless Door and Window Contact Sensor provides discreet wireless monitoring for doors, windows, and other opening applications using a rare earth magnet and 345 MHz communication. Its encrypted wireless transmission, extended battery life, external dry-contact input, and included installation spacer provide flexible protection for compatible 2GIG security systems.

• Wireless Opening Detection — Detects separation between the sensor and rare earth magnet and transmits alarm, restore, supervisory, low-battery, tamper, and external input events to compatible 2GIG panels.
• Encrypted 345 MHz Communication — Transmits in encrypted mode by default, with an onboard switch allowing encryption to be disabled when required for system configuration.
• Extended Battery Life — Includes one CR2450 lithium battery with up to eight years of service life and a 70-minute supervisory transmission interval.
• Flexible External Input — Supports external normally open or normally closed dry-contact devices for expanded monitoring applications.
• Recessed Installation Design — Includes a spacer for broader door and window applications, with a rounded exterior and square interior for accurate installation; ABS housing operates from 32°F to 120°F.
