Review: Fantastic product and company - Fantastic product, feels really solidly built. Works perfectly. As for TOPENS, their customer service is amazing - always responsive to questions and helpful with detailed advice. ## Features - Easy to Program - All the TOPENS swing and sliding gate openers can be operated by the M12 remote. Quick pairing makes it simple to add the remote to your gate opener system with the programming button on the control board. The M12 remote will operate a third-party gate opener whose control board accepts “Normally Open Dry Contact” signal for push button, and connects with our ERM12 receiver (NOT incl.). The ERM12 can be powered by 9-24VDC from the control board or external power source. - Safe to Use - TOPENS M12 remote control transmitter is a 4-button wireless controller and works with all the TOPENS gate openers. Simply press the button to enjoy instant access to your property. The advanced TOPENS security code technology ensures the safety of the gate opener system. Small & easy to take wherever you are. The remote control is well built with a durable metal frame for long-lasting performance. - Smart Design - M12 gate remote provides excellent operation range of 20 meters. One TOPENS gate opener can pair Max. 8 M12 remote controls on its own, and up to 250 with the ERM12 External Receiver (NOT incl.). Every time you press the remote control will make the gate operate between open-stop-close-stop-open. For sliding gate opener, button B is designed to activate the midway mode. The 2 x 3V lithium button cell CR2025 batteries (incl.) last up to 1 year at 5-10 activations per day. - Flexible Operation Mode - If there is no signal interruption, one M12 can operate countless gate openers simultaneously within the control range. In addition, one M12 is allowed to control multiple gate operators separately: (1) four swing gate openers (2) one sliding gate motor and two swing gate openers (3) one sliding gate motor, and two more sliding gate motors by adding two ERM12 to each control board respectively, and program button C/D for regular operation without midway mode. - Exceptional Customer Support - All the TOPENS products come with a 12-month war-ranty against defects, a 30-day exchange & return and excellent tech support.
