Precision Power Transfer, 12 Conductor, Quick Connect

Twelve conductors run through the Precision EPT-12C. That is a high count for a single transfer, which is what you want when one opening has to carry several circuits at once: an electrified lock or exit device, a request-to-exit signal, a door position switch and a monitored strike can all share the same crossing without a second transfer. If the opening only needs power to a strike or a mag lock, a 2-conductor unit like the BEST EPT-2 covers it with far less wire to dress into the hinge side.

Three different approaches, depending on the opening. The Securitron EPT and the square-cut Securitron SEPT are both heavy duty transfers that mortise into the frame and door edge, the SEPT for a square-cut prep rather than a round one. The Securitron CEPT is a concealed transfer. If you would rather not cut the frame at all, a surface door cord such as the Securitron TSB-C runs the wire in an armored loop on the face of the opening, which is quicker to install but leaves the cable exposed. For lower conductor counts on the BEST side, the EPT-2 and EPT-5 cover 2 and 5 conductor runs.

The Securitron CEPT concealed electrical power transfer carries a fire rating in its specifications. The Precision EPT-12C is a 12 conductor quick connect transfer for commercial electronic access control openings; where the door assembly on the drawing calls for a fire rated transfer, specify the CEPT.

The BEST EPT-12-C is the same 12 conductor quick connect electric power transfer, catalogued under the EPT-12C series and carrying the Precision Hardware Inc (PHI) EPT-12C name in its own description. If you are matching an existing 12 conductor transfer in a door and frame already prepped for it, that is the direct counterpart.

Yes. The BEST EPT-2 is a 2 conductor electric power transfer with armored flex conduit, and the BEST EPT-5 is a 5 conductor unit with a stainless steel housing. The EPT-12C carries 12 conductors, so it suits openings where you are running latch power plus monitoring, request-to-exit and card reader circuits through the same transfer. For a single two-wire load, the 2 conductor unit covers it.

No, and it is the substitution most often made by mistake. The Securitron TSB-C is a tamper resistant door cord - a surface applied loop that carries wire between frame and door without any mortised prep. The Precision EPT-12C is an electrical power transfer, a 12 conductor quick connect unit for concealed transfer through the door edge and frame. A door cord is visible on the opening; a power transfer is not. If the specification or the aesthetic calls for concealed wiring, the door cord will not satisfy it.

Quick connect means the EPT-12C lands its wiring with plug-together connectors instead of asking the installer to strip and splice twelve pairs in the frame. On a twelve conductor crossing that is the difference between a wire-nut nest above the door and a connector you seat once. It matters most on retrofit work where you are terminating in a tight hinge-side raceway.

Same part, two brand labels. Precision Hardware Inc is the PHI line, and the BEST catalog lists the identical EPT-12C 12 conductor quick connect electric power transfer under its own SKU. Order whichever badge your spec calls out.

Two Securitron units are specified heavy duty: the EPT electrical power transfer and the SEPT square-cut electrical power transfer. The SEPT is the square-cut version, which is the one to look at when the frame and door edge prep is square rather than beveled. Both are single-piece transfers; the Precision EPT-12C is the 12 conductor quick connect unit, so if the opening needs twelve circuits you are choosing on conductor count rather than duty designation.

Across a facility with mixed conditions you will usually carry two or three. The Precision EPT-12C covers the high conductor count openings where an electrified lock, monitoring and reader circuits all cross the hinge edge. The BEST EPT-2 handles two-wire openings such as a single electric strike or maglock circuit. The Securitron CEPT is the one to hold for fire rated assemblies, since it carries a fire rating. Concealed transfers all require door and frame prep, so set the prep standard first and the part list follows.

Commercial. The EPT-12C is built for the electrified openings you find in offices, schools and multi-family common doors, where the access control system needs power and monitoring carried from the frame into a moving door leaf. Residential doors almost never need a twelve conductor crossing.

The BEST EPT-5 is built with a stainless steel housing and carries 5 conductors. The BEST EPT-2 uses armored flex conduit over its 2 conductors. The Precision EPT-12C is the 12 conductor quick connect unit, so if you need both twelve circuits and a stainless housing you are choosing between conductor count and housing material, not getting both in one part here.
