BEA's 900 MHZ FAMILY Compact transmitters and receiver allow wireless activation of any door control. FCC Part 15 certification ensures proper compliance with federal radio frequency regulations. 900 MHz Wireless technology provides greater line-of-sight transmission distance than legacy wireless frequencies. It also provides better penetration of obstacles such as walls, partitions, doors or low-emissivity glass. BEA's 900 MHZ FAMILY series of wireless devices includes the touchless retrofit transmitter for easy upgrade of touch push plates to touchless solutions, which typically require additional wires to be run for installation. The 900 MHZ FAMILY industrial series offers a line of IP65 rated hand-held transmitters, ideal for industrial environments. This family also has a convenient beltclip accessory.
