Z - Key Exchange

| The Z key exchange box is a product designed to enable the release of keys by insertion of an initial key. The Z box is suitable for releasing up to five, with the keys being released in any order once the isolation (end key) has been inserted. The requirement for this type of product usually arises due to there being more keys required than the initial isolation system supplies. The unit will generally be the link between the isolation locks and the access products. The Z box is supplied in an enclosure suitable for surface mounting. | ||||

| 1 in to release 2 example. The isolation key is free and the two secondary keys are trapped. Insertion of the isolation key enables the removal of the secondary keys. Once the first secondary key has been removed, the isolation key is trapped. All secondary keys must be re-inserted to enable removal of the isolation key. | ||||

The ‘Z’ is designed to operate as part of an integrated safety system. A typical example is shown below.
 |

|
|

The electrical supply to the machine is switched on and the access doors to the hazardous area are locked closed. The initial key is trapped in the KS32 Lock. To enter the area, the key in the KS32 is released, locking the switch off. This key is then inserted into the ‘Z Key Exchange Box’ to release a further two keys which are used to open the ‘AIE’ and ‘AI’ access locks on the doors. Whilst these keys are out of the ‘Z box’, the initial power supply cannot be switched on. |
