User manual KIRK KEY STANDARD BRASS INTERLOCKS

[. . . ] 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. [. . . ] 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. IB/B-T/06 SECONDARY PAGE 6 PRIMARY 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. 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.

Lock Bolt 2) Run wires into the switch housing and terminate on appropriate terminals. 4) T the wiring to verify that the circuitry corresponds to the proper lock bolt position. est Type F Interlock Type F Interlock with Type SS Auxiliary Switch Lock Bolt Withdrawn Wiring of Type K Auxiliary Switches Denoted by a "1" in column four of the interlock part number. KFL 1 00010S-CM) The Type K auxiliary switch is an option that is available for most styles of interlocks. The Type K is normally a DPDT quick-make, quick-break toggle switch. (Note: other styles of toggle switches are available by special , order) Contact Arrangement: Lock Bolt Extended Contacts Closed: 1-2, 4-5 Lock Bolt Withdrawn Contacts Closed: 2-3, 5-6 Instructions for wiring the Type K Switch: 1) Remove the cover. 2) Remove the toggle switch (three screws). 3) Run the wires into the switch housing and terminate on the appropriate terminals. 4) Reattach the toggle switch to the housing (three screws). 6) T the wiring to verify that the circuitry corresponds to the proper lock bolt position. est Note: The Type S and Type K Auxiliary switches cannot be added to existing interlocks in the field.

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. [. . . ] 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.
