The RCM020 provides simple on/off control and can be useful for Master House control applications.

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 and RLF (screwless) options are for flush mounting only.
