    Product specifications for the 2GIG-DW100-345 Indoor Door/Window Contact sensor — a wireless magnetic security sensor with switchable encryption, part of the 2GIG 345S sensor family.

    Overview

    The 2GIG DW100-345 Door/Window sensor is a reliable and versatile sensor designed to protect homes and businesses. It operates at 345 MHz to communicate with 2GIG security panels, transmitting signals when the magnet is separated from the sensor. It can be installed on doors, windows, and many other objects that open and close. The sensor transmits in non-encrypted mode by default and can be set to encrypted mode via an on-board switch.

    Key Features

    • Designed for a seamless fit with an included spacer, enabling more door and window applications
    • Battery life of up to 8 years, reducing frequent replacement and truck rolls
    • Rounded outer with square interior enables accurate installation for optimized installer experience
    • Supports external Normally Open or Normally Closed input
    • On/Off switchable encryption
    • Stock half as many SKUs on trucks — one sensor works for both encrypted and non-encrypted operation via internal switch

    Compatibility

    2GIG 345S sensors work with the all-new GC Touch, the revolutionary 2GIG EDGE, and earlier security & control panels from 2GIG, forming a complete 2GIG security ecosystem. The 345S sensor family includes contact, PIR, glass break, smoke detectors, keyfobs, and more.
