The Miller Edge GEM-102 Gate Edge Module is designed to interface a hardwired 10K resistive monitored sensing edge with a commercial gate operator that requires a 2-wire pulsed monitored safety input. It does not make a damaged edge safe and it should not be used to disguise a missing or incorrect safety device. Instead, it translates the signal from a proper 10K gate edge into the monitored signal style required by the operator. The correct GEM model depends on the operator input: GEM-102 is for 2-wire pulsed, GEM-103 is for 4-wire pulsed, and GEM-104 is for normally closed monitored input applications. Select the module from the operator manual, Miller Edge compatibility guidance, or the approved edge worksheet for that operator.

The GEM-102 is not interchangeable with the other GEM modules unless the operator input type also changes. A 2-wire pulsed input, 4-wire pulsed input, and normally closed monitored input are different safety input styles. Use the exact model required by the operator documentation.
Safety edge and sensor wiring affects entrapment protection. Do not bypass a required monitored safety input or substitute a non-monitored device where the operator requires monitored protection. For commercial doors, vehicular gates, high-voltage controls, or any unsafe movement condition, have the system inspected and tested by a qualified door or gate technician.
It converts a hardwired 10K resistive monitored gate sensing edge signal to a 2-wire pulsed monitored output for compatible commercial gate operators.
No. It is intended for a 10K resistive monitored sensing edge. It should not be used with the wrong edge type.
Choose by the monitored input type required by the gate operator: 2-wire pulsed for GEM-102, 4-wire pulsed for GEM-103, or normally closed for GEM-104.
No. GEM modules are for hardwired 10K edge installations. Wireless edge systems use compatible transmitter and receiver hardware.
Test edge activation, operator stop/reverse behavior, LED status, and all monitored safety inputs according to the operator and safety device instructions.
