The cut found above the tip of the key is called Cut #1, and so on to the bow of the key. Again, cutting this type of a key by code is different than cutting a stan- dard pin tumbler key. Cuts Next to the "Peak" Also note that in the position next to the peak on the key, the machine will cut off the peak if you use a #7, #8 or #9 cut in the A2 system or a #4 or #5 cut in the A4 system. This challenge previously required the use of an asymmetrical cut- ter, such as the 1011. However, Kaba has developed a milling cutter that elimi- nates all MACS violations and all "cuts next to the peak" restrictions on both the .140" and the .150" products. The angle of the cut on one side is 37 degrees and 42 degrees on the other side. There’s a leſt-hand and right-hand version of the cutter available. Framon, ITL and HPC also manufacture key machines that cor- rect this situation. To avoid the problem, one might progress these positions last when you are master keying, or not at all, if possible. MACS Notice that MACS (maximum adjacent cut specification) for the Peaks .150" spac- ing is 9. In other words, no forbidden combinations. However, for the 140 fam- ily, the MACS are 8 for A2 and 4 for A4. This is because the spacing from cut to cut is closer than in .150" spacing. More on .140" and .150" Spacing The Peaks family of cylinders uses a .140" spacing from one chamber to the next providing interkeyable mortise, rim, LFIC and SFIC cylinders. These cylinders use a 6-pin locking mechanism (the 7th is the patented pin stack, consistent in all Peaks products). However, for end users who wish only to use Peaks SFICs, then a special .150" spacing interchangeable core is available. Understand that these .150" cores (spaced at .150") can’t be interkeyed with the other .140" Peaks family of cyl- inders, though standard SFIC tools and equipment can still be used. Pins and the Peaks Pin Kit What seems to confuse locksmiths most is the fact that there are different bottom pins required for A2, A4, SFICs and LF- ICs. To add to the misunderstandings, the standard bottom pins for Peaks are .003" shorter than conventional SFIC bottom pins. The top pins are the same. All of these variations are covered in depth in the Kaba Peaks Technical Man- ual. Originally written in the 1990s by Jack Hobin, CPL, with Jerome Andrews, CML, it’s been updated over the years. The manual details all of the small nu- ances within the Kaba Peaks line, in- cluding product information, key cut- ting and combinating instructions for each product, key control and record keeping, calculating pin stacks and a complete cylinder installation guide. It should be on your shelf if you’re work- ing with the line. Figure 5. Originally written in the 1990s, the Peaks Preferred/Classic Technical Manual has been updated over the years and details all of the small nuances within the Kaba Peaks line. MACS = 8 for .140" spacing in the A2 System (0-9 or 9-0 forbidden) MACS = 4 for .140" spacing in the A4 System (0-5 or 5-0 forbidden) MACS = 9 for .150" spacing in the A2 System (none forbidden) MACS = 5 for .150" spacing in the A4 System (none forbidden) Pinning Kaba Peaks All products in the Peaks line can be combinated with Kaba Peaks A2 Pin Kit #3400-00-5012, with the exception of the Schlage 6440 retrofitted LFIC (it will require the Kaba Pin Kit No. 6440- 00-5002). All Peaks cylinders, including fixed and ICs, can be top loaded and will use a spring cover (excluding individu- ally capped SFICs). For those using an A4 system, Pin Kit #3400-00-5004 would be used. 36 KEYNOTES OCTOBER 2016 WWW.ALOA.ORG
