KIRK Key Transfer Panels

A transfer panel is a group of primary and secondary locks involved in a transfer step. primary

keys must be inserted in the transfer panel and turned before secondary keys can be released.

Primary keys are generally related to power sources (such as breakers, T/R switches, level

detectors, etc.) and secondary keys are related to access doors.

In the normal operating position, all

secondary keys are “trapped” in the

transfer panel and all primary keys are

“trapped” in upstream equipment. All

upstream equipment must be locked safe

in order to release the keys for insertion in

the primary side of the transfer panel.

The secondary keys are then released

allowing access to equipment (such as

hopper doors, manholes, access doors).

Access doors must make use of key

retaining interlocks, such as the Type D,

DY, or DM so that the secondary keys are

trapped at the access point until the

access openings are properly closed.

Two or more transfer scheme systems

can be provided in one transfer panel

enclosure however most enclosures are

designed to house a single system.

It is important that the installer understand

the entire key interlock system(s) and the

intended purpose.
