MJU01Xor 4 LR20 type 1.5 V alkaline batteries• 5-year battery life (with MPU01X battery) or 3-year battery life (with 4 LR20 batteries) (2)• Wiring using 4 wires between the outdoor caller unit and the controller• Control and powering of any type of low consumption (0.5 A max.) 12 V latches.• Control of safety ELV motorisation system able to operate with a 48 V DC/1 A dry contact (relayor switch)• All controller inputs/outputs are SELV typesInternal handset unit data• Interior boxes made of ABS• Degree of protection: IP31/IK04• Operating temperature from -5°C to +55°C• Base powered by mains supply: via 220 V/6 V transformer• Rechargeable handset powered by MTU01X plug-in lithium-ion battery• Rechargeable handset battery life when off base: 15 days (3)• Battery base battery life: 5 years (3)(1) The free field range corresponds to the maximum theoretical distance separating the controller and the handset whenthere are no obstacles in the way (e.g. wall, screen, vegetation, electromagnetic disturbance, etc.) likely to reduce therange.(2) The battery life is based on household use, i.e.: 2 x 10-second communications, 7 latch commands and 6 gatecommands per day for a controller and an outdoor caller unit without digicode, 1 x 10-second communication, 4 latchcommands (without outdoor caller unit backlighting) and 5 gate commands (without outdoor caller unit backlighting) perday for a controller and outdoor caller unit with digicode.(3) The battery life is based on household use, i.e. 2 x 10-second communications, 2 x 10-second inter-handsetcommunications and 6 commands (2 latch commands, 2 gate commands, 1 lighting command, and 1 garage doorcommand) per day. For the rechargeable handset battery life to last its full period (15 days) when off its base, it must beleft on its base to charge for at least 2 days when it is first powered or 4 days if the display screen disappears (duringwhich time it can of course be used).12.
