The ETC ERP-TPH is a tamper-proof hardware kit designed for the Unison Echo Relay Panel. For installed lighting systems in schools, public venues, commercial spaces, and other environments where equipment security matters, this accessory helps limit unauthorized entry to the panel interior. Its special screw heads provide a practical layer of physical access control for relay panel installations that need added protection.

This kit is best suited for integrators, facility teams, and contractors specifying lighting control infrastructure in shared or publicly accessible areas. Rather than changing panel operation, the ERP-TPH supports a more secure installation approach by making the enclosure harder to open with standard tools. That makes it a useful choice when protecting internal components is part of the project requirement.
