The MX 12 Key System is box mount only
Up to 3 keys trapped and 9 released, the “initial keys” which are usually in the power isolation parts of the system are removed from the isolation boxes or panels and put in the first row in the MX Multi Key Exchange panel to allow access to the guarded areas when required.
Once the “initial keys” have been placed in the first row of the MX Multi Key Exchange panel and turned then all the other keys in the panel can now be retracted (non-sequentially) and moved to the other parts of the system. Due to the flexibility of the MX Multi Key Exchange System up to 9 keys can be released.
The end user has the option to configure and retrofit extra barrels to systems i.e. if the end user initially specifies a system with 2 keys trapped and 8 keys released this can be upgraded with the addition of extra barrels until the full 3 keys trapped and 9 keys released maximum is reached.
