Exception for Monitored Safety Inputs
TGM-500™ was built around the use of universal, Normally Closed (NC) safety sensor inputs. However, to ensure broader industry participation and compatibility, an exception is allowed for gate operators that use monitored safety inputs, only if the following conditions are met:
- The operator must stop or reverse immediately when a safety device is triggered or fails.
- The system must allow field verification of both open and close direction safety devices.
- The operator must not require proprietary sensors that restrict safety functionality to a specific brand.
- All other TGM-500™ performance requirements (force limits, auto-close delay, manual release, etc.) must still be met.
This exception is designed to allow commonly used systems to participate in the TGM standard without sacrificing the field accountability, testability, and safety performance that TGM was created to uphold.

Free Training
This free class is designed to introduce installers, inspectors, and industry professionals to the TGM-500™ and TGM-501™ safety standards.
The training walks through why these standards were created, how they improve field safety, and how professionals can use them to verify compliance with confidence.
