Although each RCP07 keypad and RAH07 remote control have a very conservatively specified indoor range of 15m, there are instances when this may need to be extended. The RAB100 is an all-house-room-channel, receive and re-transmit unit, capable of sending Rako RF commands up to 100m from their control point. Using its plug-and-play design, you simply choose a convenient mid-point location, within 15m of the keypad, and plug the unit into any available mains socket. For single or adjacent room control, a RAB100 would rarely be required. If whole-house control is to be provided within a very large property, or where certain modules are located some distance from a keypad, the RAB100 will relay the RF commands of any Rako keypad or remote to its required module.
