ERM12 External Receiver:

TOPENS ERM12 External Receiver is designed to receive signals from TOPENS wireless access devices such as remote controls, push buttons and keypads. It then transmits these signals to the gate opener, triggering its opening or closing. With advanced TOPENS code technology, ERM12 establishes a reliable and secure connection between the gate opener and remote control devices.

Compatibility Check:

Before proceeding, confirm that your gate opener accepts the "Normal Open Dry Contact" signal for the push button. Check your user manual or consult the manufacturer of your gate opener for this information.

ERM12 Installation:

Once compatibility is confirmed, add an additional ERM12 External Receiver (available at TOPENS Store) to your existing gate opener. Follow the ERM12 user manual to connect its wires to the control board of your gate opener.
