Installation Instructions
Proper installation of key interlocks is a critical element of a key interlock system. It is essential that
each SKPM, SKRU, or TDKRU be installed so that the key(s) cannot be released unless the
equipment to which it is installed is in the proper position/condition. After installation of the interlocks,
the complete interlock system should be tested sequentially by person(s) familiar with the entire
system and its intended purpose. Any problems or discrepancies must be corrected prior to
energization.
Each interlock is supplied with a key in each cylinder. These keys are needed during installation of
the interlocks. Once the complete interlock system is installed, all extra keys must be removed from
the system and destroyed or retained by a responsible person. There should only be enough keys to
operate the interlock system sequentially. Kirk Key Interlock Company will not be responsible for
extra keys left in the interlock system.
