The Model DVS-2400 24-channel Supervised Wireless Security Console is a wireless console intended for apartments, condos, townhouses, homes, and any other sites that require 24 zones of protection or less. The system features a full-function, built-in keypad with an LED display of each sensor/transmitter. The DVS-2400 is a uniquely-styled, ultra-compact, UL listed console with a concealed antenna for surface, flush, or tabletop mounting. The heart of the console is a superheterodyne radio receiver. A rechargeable back-up battery also fits inside the console (not included). The Model DVS-2400 has six operating modes and can be configured for one-button operation, for eight user codes (including duress), and to the SIA false alarm standard. An optional plug-in Model VB-3 board adds valuable communications capabilities, including voice prompts, and touch-tone telephone access. Compatibility with the industry’s widest line of transmitters and sensors (Linear’s supervised DXS series and non-supervised DX series) means systems can be tailored by site and by need. Available models include door/windows, smokes, glass breaks, bill traps, keypads, and single and multi-channel personal transmitters in a variety of styles (handhelds, pendants, minis, and wristbands). Installation and programming are made easy by Linear’s RA-2400 remote access software.
