Wireless Key Fobs For Security And Control Systems

Low Power Radio Solutions has introduced a range of multi-function wireless key fobs for manufacturers of security and control systems. The new wireless key fobs are available in a number of different designs, providing a range of control options and case designs to complement end-system aesthetics. The range is made up of six different models all operating at 43392MHz and housed in ABS cases.

All feature the Keeloq software data encoding system derived by Microchip Technology to ensure safe and secure transmission of control signals from the key-fob transmitter to the receiver. The Ring, Duet and Alien models are two-channel devices with transmission power of <+4dBm. They feature a low-battery indicator and transmission indicator using two LEDs, in red and green, measure 35 x 50 x 10mm and are fitted with rubber actuating buttons.

The Banan offers three channels and has a transmission power of <+2dBm and dimensions of 68 x 25 x 15mm with plastic buttons. The Lider and Quartet key fobs are four-channel devices with transmission power of <+4dBm. They both feature LED low-battery and transmission indicators, dimensions are 35 x 70 x 14mm, with plastic buttons on the Lider and rubber buttons on the Quartet. The RSC-2 wireless key fobs are said to complement the existing AMTX2B-4-ER transmitter already available from Low Power Radio Solutions.

This two-button key fob AM transmitter operates at 434MHz and features the company's easy-Radio software, allowing instant wireless communication with a matching receiver. On-board software can be customised to suit specific requirements and may be reconfigured up to a minimum of 1,000 times. The AMTX2B-4-ER offers reliable communication over an extended range, operates in ASK format and features an LED indicator to confirm transmissions.
