Key Operated Exchange Unit



Intermediate Key Transfer Application – One Isolation Point, Multiple Access Points


Where there is one point of isolation, which allows access to multiple points of access, an intermediate transfer is required. In this trapped key system, the intermediate transfer system is a key exchange



In this solution, electrical power is isolated with a key switch on the left side of the image. The key is freed and entered into the key exchange system (intermediate transfer). Only when the isolation key is inserted, can the keys for access be released. In the image below, four points of access are controlled through this intermediate transfer (key exchange system). Whilst any of the keys are entered into the access points, the isolation key will remain trapped in the intermediate transfer and hazardous energy cannot be restored to the system.

How to Design Your Key Exchange / Intermediate Transfer?






1. Material


Key exchange ‘XM’ modules come in two different varieties, robust metal alloy (XM) or Full Stainless Steel (XMS).



Harsh Environment Key Exchange Dirty Dusty

XM – Robust Metal Alloy   |   XMS – Full Stainless Steel







2. Environment


If operating in extreme conditions such as cold temperatures, saltwater exposure, external ‘weathered’ locations, or wet & humid environments including where wash down is performed, the stainless steel (XMS) option is recommended.



Protect your Locks from dust and particulate ingress. Padlock-able dustcovers can receive up to two padlocks per lock.
