The Paradox RF Expander Module provides connectivity of the Concept 4000 system to the Paradox Magellan range of wireless devices. The Expander Module allows seamless functionality for both wireless zone inputs and remote control fobs . Selected remote control fobs provide bi-directional sound and visual feedback when arming or disarming the system and when controlling auxiliary devices. In addition to this some remotes feature an information button which can be used to indicate the current status of the particular area. All fobs have buttons which can be programmed to provide different actions, and wireless PIN verification is also provided on some fobs. Each module provides 32 wireless detection zones, low battery supervision & reporting for all zones. Wireless detectors provide ease of installation time and cost saving, whilst key fobs provide secure arming and disarming of the system as well as remote operation of outputs such as lighting and doors, etc. The REM2 (previously MG-REM2) is a water-resistant 5-button remote control that provides the user with the status of their system by pressing the [ i ] button. The remote control provides both auditory and visual feedback in an attractive streamlined style.
