Installation Instructions

Proper installation of key interlocks is a critical element of a key interlock system. It is essential that

each interlock be installed so that the lock bolt cannot be extended unless the equipment on 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, the key routing,

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.

Key interlocks with multiple cylinders require the insertion of all keys before the lock bolt can be

extended or withdrawn. Likewise, transfer blocks and transfer panels (which do not have exposed

lock bolts) require insertion of all keys before the operating bolt can be extended or withdrawn

allowing release of previously held keys. Do not try to force a multiple cylinder interlock that does not

have the correct keys fully inserted in every cylinder!

INTERLOCK INSTRUCTION MANUAL All KIRK Key Interlocks (Type F, FN, B, NT, T, U, FR) The key interlock should be mounted so that the 5/8" lock bolt can be extended to lock the device in the proper position. In the unlocked position, the lock bolt should be blocked from extending, thereby trapping the key(s) in the interlock.

INTERLOCK INSTRUCTION MANUAL KIRK Door/Access Interlocks (Type D, Type DM, Type DY) Type D Door Interlock All Type D interlocks have two parts: a main body with one or more cylinders and a latch block. Proper alignment of both parts is crucial to the operation of a Type D interlock. When the main body is separated from the latch block, the lock bolt is retained in the withdrawn position by concealed latch pins. Thus the key(s) is always held in the lock whenever the two parts are separated.
PAGE 4
INTERLOCK INSTRUCTION MANUAL Type DM Access Door Interlock All Type DM interlocks have two parts: a main body with one or two cylinders and a latch bolt with chain. When the latch bolt is separated from the main body, the key(s) is trapped in the lock. When the door on which the interlock is mounted is properly closed, the latch bolt can be inserted into the main body and the key can be turned and released.
PAGE 5
INTERLOCK INSTRUCTION MANUAL Type DY Access Door Interlock All Type DY interlocks have two parts: a main body and a latch block-bolt eye. When the main body is separated from the latch block-bolt eye, the key is retained and cannot turn in the lock. Thus, the key is always held in the lock when the two parts are separated. Once the door or gate is closed and the latch block bolt-eye is engaged with the main body of the lock, the key can be turned and released.

INTERLOCK INSTRUCTION MANUAL KIRK ® Key Transfer Panels Two or more transfer scheme systems can be provided in one transfer panel enclosure however most enclosures are designed to house a single system. SECONDARY 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.

INTERLOCK INSTRUCTION MANUAL Wiring of Type S Auxiliary Switches Denoted by a “ 3”, “ 4”, “ 5”, or “ 6” in column four of the interlock part number. (EX. KFL 3 00010S-CM) Auxiliary switches are an option for most styles of interlocks. Four different styles of slow-make, slow-break S switches are available as shown by the chart below.

INTERLOCK INSTRUCTION MANUAL Wiring of Type TPS (and TPSS) Interlock Switches The type TPS interlock is a key actuated switch designed for back-panel mounting. The TPS has two normally open and two normally closed contacts and the TPSS has four normally open and four normally closed contacts. The contact blocks are clearly marked with the status of the contacts. After wiring, the installer must test the wiring to verify that the circuitry corresponds to the key position (trapped vs. free).

INTERLOCK INSTRUCTION MANUAL Key Control IMPORTANT - To ensure correct operation of the KIRK ® interlock system it is necessary to remove all loosely or removable held keys before operating the equipment on which the interlocks are mounted. There should only be enough keys to operate the interlock system sequentially. The keys removed from the KIRK ® interlocks should be returned to Kirk Key Interlock Company, Massillon, Ohio, or retained by authorized personnel for use as spare keys.
PAGE 10
INTERLOCK INSTRUCTION MANUAL Service and Maintenance Lubrication - Interlocks should be periodically lubricated with a small amount of dry powdered graphite. Do not use oil of any type as the oil will collect dirt and "foul" the lock cylinder so that it will not operate. Apply a small amount of graphite to the key and insert the key into the lock cylinder. Work the key in and out and turn the key several times in order to distribute the graphite inside the lock cylinder.

DUPLICATE KEY RELEASE FORM we have no way of evaluating your need for the duplicate or replacement key(s) that you have requested. At this time, we must emphasize the potential dangers associated with the misuse of a duplicate or replacement key to circumvent the sequential operation of a key interlock system and thereby defeat the protections afforded by the key interlock system.
