The RCM-070 wireless push button control module provides four scenes, off and master raise & lower and offers full scene programming. Wireless keypads are lithium battery powered with battery life calculated as being 3 years, based on pressing a button 30 times a day. Externally powered versions of the panels are available. Based on the 50 x 50mm Euro module, RCM units are modules only and always require a front plate kit. Panels can either be surface mounted using the pattress, which gives a depth of 14mm, or flush mounted into a standard single gang UK back-box. Rako’s single gang RVF (screw-fixing) front plate kits have surface mount options. Double gang, RLH and RLF (screwless) options are for flush mounting only.
