Digital Security Controls (DSC) adds greater wireless convenience and reliability to its security systems with the new WS4939 wireless key. The WS4939 incorporates new features and benefits into a sleek design that is compact and ergonomically designed. It uses activation delays for arming and disarming, as well as an extended delay of its panic function. An enhanced, integrated LED indicator signifies that a transmission has been sent by the WS4939 to the security system. With easy-to-read icons and a multi-functional clip – allowing the key to attach to a belt, car visor or safely inside a purse – the WS4939 is convenient and user-friendly. Optional covers for the WS4939 are available in eight designer colors. The WS4939 utilizes reliable 433 MHz wireless technology, uses long-life lithium batteries and is compatible with all of DSC’s current wireless receivers. DSC
