DOLD M10-12 Trapped Key Interlock System

DOLD SAFEMASTER STS M11BM/K Trapped-Key Guard Lock
STS-M11BM/K is a mechanical SAFEMASTER STS guard-lock configuration with a separate actuator and forced key removal. In the supplied sequence, inserting the first key permits removal of the second key and then the actuator. This creates a defined mechanical access sequence; its behavior must be distinguished from electrically monitored STS switches and from separate power-interlocking assemblies.
Review Summary
Consider this configuration when a mechanical key exchange can enforce the required access order. Confirm the exact unit, keys and actuator against DOLD’s current drawings before purchasing. Mechanical key transfer can preserve authorization without control wiring at each access, but it does not itself establish that all hazardous energy has dissipated.
