25-03-2020 news

ALUTECH presents a new product in the line of ALUTECH automation — the CUR radio receiver (Fig. 1). The device is designed for convenient control of roller shutter electric drives both with the help of ALUTECH remote controls and by pressing buttons on the device casing.

It is also possible to connect additional control and safety devices to the radio, such as key and lock switches (in SBS mode — step-by-step mode for one-button operation), photocells, optical and resistive safety edges, signal lights (Fig. 2).

The new device has a number of advantages compared to the CURD-1 control unit, which has been discontinued.

Operational safety and solid design:

  • Enhanced IP protection. You can install a CUR receiver nearly anywhere.
  • Protection against unauthorized access. The cover of CUR is fixed with self-tapping screws, which blocks access to the board (screws are supplied).
  • Extra safety (when connecting appropriate safety systems1). The manufacturer provides protection against pulling foreign objects into the box, as well as protection against squeezing and jamming.
  • Availability of the «dead man» operating mode. This mode allows operating the drive even if the connected safety systems fail.

Comfort and ease of use:

  • Variety of control methods. Control with the help of the keypad on the device casing, plug-in controls (key and lock switches), control with any type of ALUTECH remote control or radio timer (AT-1(S), AT-15(S), AT-4N, AT5(S)/RT).
  • UBS-mode (rolling mode). Allows you to control a rolling system using 3 buttons of ALUTECH remote controls or radio timers: «up», «stop», «down».
  • New installation scheme for the radio. Convenient mounting scheme of the CUR unit allows you to easily install the radio on the mounting surface without the need to mark holes for fastening.
  • Increased size of connection terminals. A solution which provides easy wiring of control and security devices.

Thanks to an improved design, enhanced technical characteristics and expanded functionality, the new CUR radio receiver meets the highest requirements of the EN12453 safety standard, as well as the European Directive 2014/53/EU (RED).
