What the Electrified Hardware Consultant Credential Is
The Electrified Hardware Consultant (EHC) is a professional certification offered by the Door and Hardware Institute for people who work with electrified door hardware: the electric strikes, electromagnetic locks, electrified exit devices, power supplies, access-control readers, and wiring that turn a mechanical door opening into a monitored, controlled, code-compliant one. If you are researching the topic from scratch, our overview pages on what EHC is and what EHC stands for cover the naming basics, and this article goes deeper into how the credential actually works.
A note on the acronym: several unrelated credentials in other fields abbreviate to the same three letters. Everything on this page concerns only the DHI Electrified Hardware Consultant. Facts, fees, and exam structures from any other "EHC" do not apply here, so if you have seen different numbers elsewhere, check which credential they belong to before relying on them.
What separates this certification from a general door-hardware credential is its focus on the electrical and integration side of an opening. Electrified hardware sits at the intersection of three disciplines that rarely share a job title: the door and hardware trade, the low-voltage electrical trade, and the security-systems trade. The EHC exists to certify someone who can speak all three languages well enough to coordinate them on a real project.
Who Issues It and Why It Matters
The Door and Hardware Institute (DHI) is the professional association for the door, frame, and architectural hardware industry, and it administers a family of credentials, including the Architectural Hardware Consultant (AHC) and the electrified-focused EHC. DHI publishes the competency statements the examination is built on, along with its certification policies, continuing education rules, and course catalog.
For a broader introduction to the credential family and how it is positioned, see our companion pages on EHC certification and what EHC certification is.
Who Pursues and Hires for This Credential
The people who tend to pursue the EHC work where hardware specification, supply, installation, or security integration meets construction. Typical profiles include:
- Architectural hardware consultants and specifiers who write the hardware sections of project specifications and need to coordinate electrified openings with the electrical and security scopes.
- Distributor and supplier staff who prepare hardware schedules, submittals, and shop drawings for openings with electric locking, door position switches, request-to-exit devices, and access-control readers.
- Manufacturer representatives who advise architects and contractors on electrified product selection and troubleshooting.
- Integrators and security professionals who need credible hardware-side knowledge to complement their access-control expertise.
- Facility and project managers who oversee openings where fire, life safety, and security requirements must all be satisfied at once.
Employers in these areas value the credential as evidence that a person can read an electrified hardware drawing, understand a wiring riser, anticipate code conflicts, and troubleshoot a failing opening. We do not cite salary figures here because we have not verified any specific numbers for this credential; if earnings are your main question, our EHC salary guide and EHC jobs page discuss what can and cannot be said responsibly, and the ROI analysis weighs the investment qualitatively.
The Four Examination Competency Areas
DHI publishes four competency statements for the Electrified Hardware Consultant examination. These are the headings the exam is organized around. DHI does not publish percentage weights for them, so you should not assume any one area is worth more than another; prepare for all four. Our complete guide to the four EHC content areas expands on each, and the summaries below show what they mean in practice.
Domain 1: Advanced mechanical and electrified hardware product
This is the product-knowledge foundation. Candidates must understand how mechanical hardware and its electrified counterparts function, how they differ, and when each is appropriate.
- Electrified locking: electric strikes, electromagnetic locks, electrified mortise and cylindrical locks, and electrified exit devices.
- Fail-safe versus fail-secure behavior and what each means for egress and security.
- Supporting components: power supplies, transfer hardware, hinges that carry current, door position switches, and request-to-exit devices.
- Low-voltage circuitry fundamentals that determine whether a product will actually work on a given opening.
Domain 2: Code application knowledge with an understanding of electronic access control systems
This area joins code literacy to the systems side: how access-control components are specified and how they interact with hardware at the opening.
- How readers, controllers, credentials, and locking hardware communicate and fit together.
- Where code requirements constrain access-control design decisions at the door.
- Reading and interpreting electrified hardware drawings and riser-style documentation.
- Coordinating hardware, electrical, and security scopes so nothing falls between trades.
Domain 3: Understanding fire, life safety, accessibility, and building code requirements
This is where electrified hardware meets the rules that protect occupants. A solution that secures a door but traps people, or fails accessibility requirements, is not a solution.
- Egress requirements and how electrified locking must release under defined conditions.
- Fire-rated openings and the interaction between fire alarm systems and door hardware.
- Accessibility requirements that affect operation, hardware selection, and opening function.
- Applying building code provisions to real openings rather than reciting them in the abstract.
Domain 4: Understanding of architectural door openings and security needs
The final area ties everything to the opening itself and the owner's security objectives.
- Analyzing how an opening is used, who needs through-access, and what level of control is required.
- Selecting a hardware and access-control approach that matches the security need without violating code.
- Understanding door, frame, and hardware preparation requirements that make electrification possible.
- Communicating a recommendation clearly to architects, owners, and installers.
Key Takeaway
The four areas overlap deliberately. A single exam scenario can ask you to choose a product (Domain 1), confirm it works with the access-control design (Domain 2), verify it satisfies life-safety rules (Domain 3), and justify it against the owner's security needs (Domain 4). Study them as one connected workflow, not four silos.
Exam Format and How It Is Delivered
DHI's EHC page describes the full examination as an eight-hour, paper-and-pencil test with three kinds of sections: short-answer, long-answer, and multiple-choice. That mix matters for preparation. Multiple-choice rewards recognition; short- and long-answer sections reward the ability to write out a coherent technical explanation, such as describing how you would resolve a code conflict on an opening or laying out the components of an electrified opening from memory.
| Element | What DHI publishes |
|---|---|
| Full exam length | Eight hours |
| Medium | Paper and pencil |
| Section types | Short-answer, long-answer, multiple-choice |
| Competency areas | Four, with no published percentage weights |
| Prerequisites | None required to apply |
We have not verified a current question count, a multiple-choice-only time limit, or a passing score, and we will not guess. Our pages on the passing score and pass rate explain what is and is not publicly confirmed, and how hard the exam is discusses difficulty in qualitative terms rather than invented statistics.
Fees, Registration, and the Proctor Requirement
| Item | Amount |
|---|---|
| Examination fee, DHI member | USD 550 |
| Examination fee, nonmember | USD 850 |
| Retake fee | USD 300 |
| Renewal (one credential), member | USD 175 |
| Renewal (one credential), nonmember | USD 210 |
The USD 300 difference between member and nonmember exam pricing is worth weighing against the cost of DHI membership if you are on the fence. Our full cost breakdown walks through how to think about total spend, including preparation courses.
The proctor requirement
Because the examination is delivered on paper, candidates are responsible for arranging a proctor, and DHI's Certification Policies set firm rules about who qualifies:
- The proctor must hold the same certification, meaning an EHC-certified individual.
- You may not be proctored by a family member.
- You may not be proctored by someone employed by the same company, division, or branch as you.
- The stated exception is staff proctoring at National and Micro Schools.
This catches people off guard. If your entire team is uncertified, or the only certified colleague works in your branch, you will need to look elsewhere. Start the search for an eligible proctor early, since it can be the longest lead-time item in your plan. Our exam dates and scheduling page covers timing, and EHC requirements covers eligibility in more detail.
Retakes
DHI's materials are inconsistent on the number of permitted retakes: the generic policy sets a two-retake limit, while the EHC page references a third-retake application and directs retakes into Prolydian. Confirm your permitted attempts with DHI before you plan around a "second chance."
Published Preparation Pathways
There are no prerequisites to apply, but DHI recommends three courses: EHC403, EHC413, and EHC423. The DHI course catalog also lists an EHC490 entry. The published preparation content spans:
- Electrified hardware drawings and how to interpret them.
- Access-control integration.
- Low-voltage circuitry.
- Troubleshooting electrified openings.
- Shop-drawing exercises.
- Specification writing.
Treat this list as a map of preparation topics, not an official exam blueprint; DHI does not present it as an exhaustive statement of what will be tested. Likewise, course hours, tuition, software exercises, and class materials do not tell you anything about exam timing, fees, or which resources are allowed in the exam room. Some course materials cite historical code editions, which should not be read as identifying the code version a current exam uses. For a structured plan, see our EHC study guide and EHC training overview, and keep the one-page cheat sheet handy for quick review.
Sequencing Your Preparation Around the Domains
Because the exam includes written short- and long-answer sections, your schedule should build toward being able to explain concepts in your own words, not just recognize them. Here is one way to order the four areas, using the logic that later topics lean on earlier ones:
Domain 1 foundations
- Build a component inventory: strikes, mag locks, electrified exit devices, power supplies, switches.
- Practice drawing a basic low-voltage circuit for a single electrified opening.
Domain 2 integration
- Trace how a credential read becomes a lock release, component by component.
- Work through shop-drawing and riser exercises.
Domain 3 life safety
- Study egress and fire-alarm interaction before anything else in this block; mistakes here carry the highest consequences.
- Write out, in full sentences, how a given opening satisfies code.
Domain 4 and full review
- Practice recommending a solution from a security-need description.
- Run mixed practice that crosses all four areas, then time a long written session to build stamina for the eight-hour format.
Adjust the pacing to your background: a hardware specifier may move fast through Domain 1 and slow down at Domain 2, while an integrator will likely do the opposite. To test your recall across all four areas, try the EHC practice tests on the main site.
Keeping the Credential Active
Earning the certification is not the end. DHI's Continuing Education Program requires 30 CEP points every three years, with at least 24 of them technical. Renewing a single credential costs USD 175 for members or USD 210 for nonmembers. If you hold more than one DHI credential, check the Continuing Education Program page for how points and fees apply. Planning your continuing education as you go, rather than in the final months of a cycle, keeps renewal painless.
What Has Not Been Verified
Honest preparation means knowing the limits of public information. As of our latest research review, we could not verify any of the following for the Electrified Hardware Consultant examination, and you should treat any source claiming precise figures with caution:
- A current question count.
- A time limit for the multiple-choice component alone.
- A passing score or cut score.
- A pass-rate statistic.
- A separately numbered examination release or version.
When in doubt, go to DHI directly. You can also review the main practice test site for ongoing updates as more is confirmed.
