HES Electric Strike Service in Charlotte

HES electric strikes replace a mechanical keeper with a solenoid-released keeper so a card reader or code can free a cylindrical latch, mortise latch, or panic latch. Voltage, fail-safe versus fail-secure, and latch type are not interchangeable details. Charlotte Locksmith installs and diagnoses them independently; we are not ASSA ABLOY or HES corporate. Also heard as HES 5000-class electric strike, 12/24-volt door strike, fail-secure electric keeper. Charlotte Locksmith is a mobile, veteran-owned, bonded and insured locksmith. We write this from work on the actual opening, not from a catalog paragraph reused across a hundred URLs.

Keepers that move for a latch, not for a maglock

On HES electric strike service, solenoid and keeper is checked as its own failure path, because treating the whole product as one object hides the part that actually stopped the door. We look at it with the door standing open, then again closed, because frame collision changes feel.

Technicians isolate lip and faceplate sized to the frame prep before they blame the rest of HES electric strike service. That isolation is how we avoid replacing a sound chassis to hide a frame problem. Photos for the occupant show that part in place rather than a stock image of hardware nobody has.

If 12-volt or 24-volt coil is tired, the occupant feels it as a ‘bad lock.’ We name the part at the door so the recommendation matches the wear. Authorization still comes first when a key, code, or credential belongs to someone else.

Fail-secure versus fail-safe in plain language

A typical call looks like this: South End coworking cylindrical locks on aluminum frames. The hardware conversation starts from that occupancy, not from a national template. Cylindrical, mortise, and panic latches each have HES bodies intended for them. A deep mortise latch in a shallow cylindrical strike is a noise complaint that becomes a melted coil. We match body to latch and frame material (wood, hollow metal, aluminum).

We see Uptown tenant suite with a mortise latch more often than trade magazines admit. The inspection sequence below is written around that opening. Aluminum frames in August expand enough to preload a keeper. A strike that released in January can hold the latch in July until we recut engagement.

hospitality back-of-house on a listed hollow-metal frame teaches different habits than a showroom door. Hinges, weather, and who holds keys all change. If the reader beeps granted but the door still needs a hip-check, the strike may be releasing while the door is physically bound.

12-volt coils and 24-volt mistakes

One of the honest symptoms is 24 volts sent into a 12-volt coil. That is not a personality trait of the lock; it is a path we test. Repair stays on the table when the keeper still squares, the coil resistance is sane, and the wrong-voltage incident has not already cooked it. Replacement enters when the solenoid is open, the keeper is bent from a kick-in, or the latch family never matched this body.

When occupants describe fail-safe strike on an opening that must stay locked on power loss, we reproduce it with the door open and closed instead of guessing on the porch. Repair stays on the table when the keeper still squares, the coil resistance is sane, and the wrong-voltage incident has not already cooked it. Replacement enters when the solenoid is open, the keeper is bent from a kick-in, or the latch family never matched this body.

Keeper that does not like a 3/4-inch panic latch shows up enough in this product family that we photograph it before we unbolt anything.

Cylindrical, mortise, and panic latch families

Inspection item 01: read the lock latch height, throw, and whether it is deadlocking.

Inspection item 02: confirm fail-safe vs fail-secure against occupancy and fire conversation.

Inspection item 03: measure existing faceplate cutout.

Inspection item 04: check supply voltage at the strike under load.

Inspection item 05: inspect REX and fire-alarm interface if present.

Inspection item 06: cycle mechanically with power removed.

Cylindrical, mortise, and panic latches each have HES bodies intended for them. A deep mortise latch in a shallow cylindrical strike is a noise complaint that becomes a melted coil. We match body to latch and frame material (wood, hollow metal, aluminum).

24 volts sent into a 12-volt coil is one of the reasons people ask for HES electric strike service. Firm price before any work.

Measuring voltage at the strike

Write fail-safe or fail-secure on the ticket
Fail-secure stays locked without power (typical for entry). Fail-safe releases without power (typical where fire alarm must free the keeper). Occupancy plus AHJ conversation, not a catalog default. This is step 01 of HES electric strike service, written against 24 volts sent into a 12-volt coil.
Cut or adapt the frame to that body
We do not grind a ‘universal’ hole and call every faceplate optional. This is step 02 of HES electric strike service, written against fail-safe strike on an opening that must stay locked on power loss.
Feed filtered DC at the rated voltage
Measure at the strike, not only at the panel. This is step 03 of HES electric strike service, written against keeper that does not like a 3/4-inch panic latch.
Prove mechanical latching and powered release
Card granted, card denied, power removed — three states, three tests. This is step 04 of HES electric strike service, written against frame preps cut for a different body.

Frames we recut versus frames we replace

Repair path

We keep existing hardware when the keeper still squares, the coil resistance is sane, and the wrong-voltage incident has not already cooked it. Keeping it still includes strike, hinge, and key-control work.

Replacement path

We recommend replacement when the solenoid is open, the keeper is bent from a kick-in, or the latch family never matched this body. The occupant hears both paths before a part is ordered.

Fail-secure stays locked without power (typical for entry). Fail-safe releases without power (typical where fire alarm must free the keeper). Occupancy plus AHJ conversation, not a catalog default. That observation belongs in the repair-or-replace talk, not after the invoice.

Fire-alarm talk we will not skip

Electric strikes do not replace listed exit devices on a required exit path. That rule is applied here to HES electric strike service, particularly solenoid and keeper.

Fire-alarm interface belongs in writing with the fire contractor when that is the design. That rule is applied here to HES electric strike service, particularly lip and faceplate sized to the frame prep.

Independent service. That rule is applied here to HES electric strike service, particularly 12-volt or 24-volt coil.

Summer aluminum preload

Aluminum frames in August expand enough to preload a keeper. A strike that released in January can hold the latch in July until we recut engagement.

A Hawthorne coworking strike buzzed constantly. Someone had landed 24 VAC on a 12 VDC coil. We replaced the strike after confirming a proper filtered 12-volt DC feed and a fail-secure function that matched their after-hours plan. The cylindrical latch was never the villain.

South End coworking cylindrical locks on aluminum frames is one working example; the same tape-and-authorization process travels to Matthews, Mint Hill, Huntersville, Pineville, Concord, Belmont, and Indian Trail when the opening is this hes-strike hardware. Mobile service, no public storefront address. (704) 741-4490.

Buzz that means AC on a DC coil

After service, watch this: If the reader beeps granted but the door still needs a hip-check, the strike may be releasing while the door is physically bound.

Skip these habits: Do not jumper a 24V locker onto a 12V coil ‘just to test’.

Independent HES-class work

Someone working HES electric strike service is accountable for solenoid and keeper, then lip and faceplate sized to the frame prep, then the strike and the door that carries both. That is a different job from swapping visible trim after 24 volts sent into a 12-volt coil.

A Hawthorne coworking strike buzzed constantly. We still start with a tape and read the lock latch height, throw, and whether it is deadlocking, not with a boxed SKU.

Questions we answer at the door

Will any electric strike fit my lock?

No. Latch type, frame, voltage, and fail mode all have to match. On this opening that points at solenoid and keeper.

Fail-secure — does that mean it unlocks in a fire?

Fail-secure stays locked without power. Fire-release designs are specified, not assumed. We talk that through with the occupancy. On this opening that points at lip and faceplate sized to the frame prep.

Can you fix a buzzing strike?

Buzz often means wrong waveform or voltage. Sometimes the strike can be saved; often the coil is already damaged. On this opening that points at 12-volt or 24-volt coil.

Are you HES?

No. Independent locksmith. On this opening that points at monitoring switches on some models.

Do you install the card reader too?

We do readers, strikes, and power when that is the job. Software administration stays with the occupant’s account. On this opening that points at jamb reinforcement or aluminum pocket.

Service in Belmont as well?

Yes, electric-strike work in Belmont, Charlotte, and nearby commercial corridors. On this opening that points at power wires from a filtered DC supply, not a random transformer.
