Start by matching your system’s voltage and load with what the range supports, then consider where you’ll place it and what you want to control. This line includes a 12V wireless option operating across AC85V–250V with a maximum load of 30A (resistive ≤25A, inductive ≤20A) and a remote distance up to 328 feet (about 100 meters). It uses 315MHz/433MHz and offers output in Dry Contact or Voltage modes. You can select from modes like Moment, Self-Locking, or Interlocking, and pairing uses a Smart Learning Code to ensure the remote talks to the right receiver. The devices are suitable for burglar alarms, lighting, and roller shutter motors.
