It is NOT suggested to use the receiver in signal towers, electrical substations and confined spaces. Some buildings or obstructions may affect the control range.Please refer to the corresponding TOPENS gate opener user manual for the correct wire connection.The pre-wired cable of the receiver is 1 foot (3C x 26 AWG). Generally, the distance between the receiver and the gate opener control box should be within 16 feet and the extension cable should be 3C x 22AWG . If a good shielded cable is used, the extension distance can be up to 98 feet and the cable should be 3C x 18AWG.One ERM12 can only work for one gate operator, while one gate operator can connect two ERM12 receivers at most.Note About the M12 Remote ControlThe M12 remote cannot be programmed to the gate opener control board and external receiver at the same time, otherwise it cannot work properly.If you lose any of the remote controls, please erase and reprogram the rest to have a new code for safety.The M12 remote is NOT waterproof.Specification:Operating Voltage: 9-24VDCOperating Current: 50mAOutput: Relay SPSTChannel: Single ChannelFrequency: 433.92MHz, TOPENS Rolling CodeModulation Mode: ASK (AM)Control Range: Maximum 98ft.

After setting up and adjusting the gate travel, everything works as expected. One significant issue I had to work thru with the support staff at Topens was the inconsistent operation of the TC196 WiFi Remote that works via your smartphone. Although my indoor setup is well within the 230 meters from the gate controls (mine is about 50 meters at the most), the operation was inconsistent. It may work one day and not that afternoon. After several exchanges with Topens support, they suggested an external antenna ( https://www.desertcart.com/dp/B094MW1YMV/) that has fixed the issue. One additional tip I would offer is when you are setting up the TC196, the "paring" sequence MUST be done as fast as possible. It appears the main board only has a few seconds to press the momentary switch on the main board, then press "A" on phone, have lights flash and press "A" on phone again. It took me multiple tries to get it programmed. Again, after solving the issues with the TC196, all the operations of the gate and related components appear to be working as expected. Thanks again to the support at Topens for assistance in getting everything working! ## Features - Safe Connectivity - TOPENS ERM12 External Receiver effectively receives signals from TOPENS wireless access devices, such as remote control and keypad. It transmits signals to the gate opener, triggering the gate to open or close.

In addition, the external receiver can be used to extend the operating range of TOPENS wireless control accessories. - Pair up to 250 Remotes - Simple wire connection makes installation labor-saving. Just connect the ERM12 to the gate opener system. Program the M12 Remote Control (incl.) with ERM12 universal receiver, and then the M12 remote will make the gate operate between open-stop-close-stop-open. All TOPENS swing and sliding gate openers can be operated by the M12 remote. ERM12 rolling code external receiver can be programmed with up to 250 pcs TOPENS M12 remote control transmitters. - Wide Compability - Works with all TOPENS gate openers. It can be powered by the control board of the gate opener or by the external 9-24VDC power source.
