User manual KIRK KEY STANDARD BRASS INTERLOCKS

[. . . ] 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(which do not have exposed lock bolts) require insertion of all keys before the operating bolt can be extended or withdrawn allowing release of previously held keys.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! IB/B-T/06 PAGE 1 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.

IB/B-T/06 PAGE 2 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. [. . . ] 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.

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). FRONT VIEW SIDE VIEW Dust Covers (Available Option) Two Styles of dust covers are available to protect the lock cylinder and key against moisture, dirt, and sleet. The Push On dust cover slips tightly over the lock cylinder when the key is in the held position or removed. 3) Fax the form to Kirk Key Interlock Company for immediate delivery, at 330-833-1528. KIRK KIRK A1 A1 IB/B-T/06 PAGE 9 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. [. . . ] Specifically, IB/B-T/06 PAGE 11 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. We also must insist that any duplicate or replacement key must be secured and controlled by a responsible person to prevent any misuse of the duplicate or replacement key. Before complying with your request for a duplicate or replacement key, Kirk Key requires that you acknowledge the potential dangers associated with the misuse of a duplicate or replacement key to circumvent the sequential operation of a key interlock system and that you agree that a responsible person shall secure and control any duplicate or replacement key supplied by Kirk Key to you.
