Detex EWH8-626 – Frequently Asked Questions
1) Will a Detex EWH8 electric hinge fit a standard commercial door frame prepped for 4-1/2 inch hinges?
The EWH8 is a 4.5 x 4.5 inch five knuckle hinge, so it drops into the same mortise prep as a standard 4-1/2 x 4-1/2 commercial hinge. What it adds over a plain hinge is the frame side: you need a wire path out of the jamb at the center hole location, because the conductors exit through the center of the hinge rather than running exposed across the gap. If your existing openings already take 4-1/2 inch butts, the hinge pocket is not the work. The wire chase is.
2) What are the eight wires in the Detex EWH8 hinge and what can each one carry?
Eight conductors, split three ways: two 20AWG for power, two 22AWG for by-pass inputs, and four 28AWG for signaling. That mix is what lets one hinge run an electric lock or strike on the heavy pair while the thin conductors carry door position, request-to-exit, or latch monitoring back to the panel. If your opening only needs power to a fail-safe lock, you are buying six conductors you will not land. If it needs power plus monitoring back to access control, the 8-wire count is the reason to pick it.
3) Do I need an EWH8 8-wire hinge or is a 6-conductor electrified hinge enough?
Count your landings first. A single electrified lock or strike with no monitoring runs on two conductors, and something like the RCI 952, a 6-conductor electrified hinge, covers that plus a couple of monitor points. The Detex EWH8 makes sense when you are also carrying by-pass inputs and multiple signal returns, since its four 28AWG signaling conductors plus two 22AWG by-pass wires leave spares for door position and latch monitoring on the same opening. Ordering 8 wire when you need 2 is not a mistake, just unused copper. Ordering 6 when you need 8 means pulling the door again.
4) What is an 8-wire electrified hinge equivalent to the Detex EWH8 in 4.5 x 4.5?
The BEST CECB168-18 is the closest straight equivalent on wire count: it is a steel full mortise electrified hinge carrying 8 wires, the same conductor count as the EWH8. The two differ in bearing construction and duty class - the CECB168-18 is a concealed bearing heavy weight hinge rated heavy duty, while the EWH8 is a five knuckle electric hinge in a 4.5 inch by 4.5 inch size with 626 satin chrome finish. If the opening already has heavy weight concealed bearing preps, the BEST unit drops into that prep; if the door is hung on standard five knuckle hinges, the Detex matches what is there.
5) I only need power to an electric strike - is there a simpler electrified hinge than an 8-wire?
Yes. A single electric strike needs two conductors for power and nothing else, so the eight-wire count on the Detex EWH8 - two 20AWG power, two 22AWG by-pass, four 28AWG signaling - is more than that job uses. The RCI 952 is an electrified hinge with 6-conductor wiring and ball bearing construction, a medium duty unit that covers power plus a couple of monitoring conductors. The Design Hardware ETW2-BB5 is a 4.5 inch by 4.5 inch electrified standard weight ball bearing hinge, also medium duty, and matches the EWH8 on hinge size so the door and frame prep is the same 4.5 by 4.5. Spec the higher wire count only when you are also running request-to-exit, latch monitoring, or a by-pass input back to the panel.
6) Is the Detex EWH8 a heavy weight hinge for a high traffic commercial door?
The EWH8 is a five knuckle commercial electric hinge listed for commercial use. If your opening is a heavy or high frequency door where you would normally specify a heavy weight ball bearing butt, look at the BEST CECB168-18, a steel full mortise concealed bearing heavy weight electrified hinge that also carries 8 wire, or the SDC PTH Series, rated to 800,000 cycles. For standard weight openings, the Design Hardware ETW2-BB5 is a 4.5 x 4.5 medium duty electrified ball bearing hinge in the same size envelope.
7) Can I use an electric hinge instead of an electric power transfer or a door loop?
An electric hinge like the Detex EWH8 carries the low voltage from the hinge jamb into the door through the hinge itself, so nothing is visible at the gap. That is the reason to choose it over a surface door loop, which works fine electrically but hangs a braided cord between frame and door where people can see it and pick at it. Against a concealed electric power transfer, the hinge wins on prep, since you are already mortising for a hinge rather than routing a separate EPT pocket in the edge of the door and frame. The tradeoff is conductor count: whatever the hinge carries is what you get, in this case eight.
8) How many hinges do I need to electrify on one door?
One. The EWH8 carries all eight conductors through a single 4.5 x 4.5 hinge, so on a typical three butt opening you order one EWH8 and two plain hinges of the same size and finish. Common practice is to put the electric one in the center position, which keeps the wire run short to the lock and keeps the top hinge, which takes the most load, as a standard butt.
9) Does the Detex EWH8 hinge include the power supply or the wire from the frame back to the panel?
No. The EWH8 is the transfer point only, moving low voltage from the hinge jamb into the door leaf. You still supply the low voltage power supply sized to whatever the door hardware draws, the cable run from the panel to the hinge jamb, and the connections at both ends. Plan the jamb side as its own line item.
10) Is the Securitron EH a drop-in replacement for a Detex EWH8?
Treat it as a different hinge, not a swap. The Securitron EH is a double duty electric hinge in the EH Series, and the Detex EWH8 is a five knuckle electric hinge in a 4.5 inch by 4.5 inch size carrying eight wires. Before you order either against an existing opening, match three things: hinge height and width against the door and frame mortise, the conductor count against what the access control panel actually terminates, and the finish. The Detex is 626 satin chrome. Swapping an electrified hinge for one with a different wire count usually means re-pulling or re-terminating at the transfer point, so confirm the conductors first - that is the part that turns a hinge change into a wiring change.
11) What is the difference between a five knuckle electric hinge and a ball bearing electrified hinge?
They describe two different things about the hinge. Five knuckle, as on the Detex EWH8, counts the interlocking leaf segments at the barrel - five is the standard commercial arrangement. Ball bearing, as on the RCI 952 and the Design Hardware ETW2-BB5, describes the bearings set between those knuckles to carry the door weight and reduce friction. The BEST CECB168-18 takes it further with concealed bearings, which sit inside the barrel and are not visible at the knuckle line. A hinge can be both five knuckle and ball bearing; when you are matching an existing door, count the knuckles for the prep and check for visible bearing races to know which family you are replacing.
12) Which electrified hinge should I standardize on across a building with mixed door weights?
Split the specification by opening rather than forcing one part everywhere. For standard weight interior doors, the Design Hardware ETW2-BB5 is a 4.5 inch by 4.5 inch electrified standard weight ball bearing hinge at medium duty, and the Detex EWH8 covers the same 4.5 by 4.5 prep in a five knuckle electric hinge with eight wires when you need the extra conductors for signaling and by-pass inputs. For heavy weight doors - exterior entries, labeled stair doors, anything oversized - the BEST CECB168-18 is the heavy duty concealed bearing option and also carries 8 wires, so the panel wiring stays consistent with the Detex openings. Keeping the conductor count the same across both weights is what makes a mixed-door standard actually maintainable.
13) What finish does the Detex EWH8 come in, and will it match the other hardware on my openings?
626 satin chrome only, which is the standard commercial finish on lever locks, exit device trim and closers, so it lands next to most of what is already hanging on a commercial opening. Worth noting that on a hinge this matters less than usual: two of the three butts on a door are typically plain, and the electric one sits in the same jamb where only the leaf edge shows.
