Securing Storefronts: Commercial Locksmithing & Access Control in Austin

Commercial door hardware — the electromagnetic locks, electric strikes, door closers, hinges, and latch hardware that control access at every entry point of a commercial building — is one of the most technically and legally complex elements of a commercial access control installation. It sits at the intersection of physical security, electrical code, fire code, ADA compliance, and life safety egress requirements.

Austin has seen significant commercial development over the past decade — new office buildings, restaurant buildouts, retail centers, and mixed-use developments across South Congress, East Sixth, the Domain, and the surrounding suburban corridors. Many of these properties are being fitted out with access control as part of an initial build, or upgraded as tenant changes and security requirements evolve. In both scenarios, the door hardware decisions are consequential.

Choose the wrong lock type for a specific application — a maglock on a fire door that needs to fail-secure, for example — and you have a fire code violation. Wire it incorrectly without coordination with the Austin Energy electrical permit requirements and the low-voltage installation, and you have a failed inspection. Install it without an appropriate request-to-exit device on the egress side, and you have a potential life safety issue and an NFPA 101 violation.

This guide covers the decisions that matter — maglock vs. electric strike, fire egress compliance, wiring coordination, and the common mistakes that result in failed Austin inspections and costly rework.

The Two Core Access Control Lock Types: Maglocks vs. Electric Strikes

Commercial access control uses electrically controlled locking hardware to allow a credential (badge, PIN, mobile credential) to grant or deny access through a door. The two primary hardware types for this function are electromagnetic locks (maglocks) and electric strikes — and they work on fundamentally different engineering principles with different installation requirements, different failure modes, and different code compliance implications.

Electromagnetic Locks (Maglocks) An electromagnetic lock consists of an electromagnet mounted on the door frame and an armature plate mounted on the door. When electrical power is applied, the electromagnet attracts the armature plate and holds the door closed with significant force — typically 600 to 1,200 pounds of holding force in commercial applications. When power is removed (door released by credential or by power failure), the magnetic field disappears and the door can be opened. [1]

Maglocks are fail-safe by design: they release when power is removed. This makes them appropriate for egress doors where free exit must always be available, because a power failure automatically releases the door. But it also means they provide no physical latch — a door with only a maglock relies entirely on the electromagnetic force to remain closed, and if the maglock loses power for any reason (intentional power disruption, electrical failure), it releases immediately.

Electric Strikes An electric strike replaces the standard door strike plate — the fixed metal plate in the door frame that the latch engages with when the door closes. An electric strike has a moving keeper that can be electronically released, allowing the door’s latch to retract from the strike and the door to open, even though the physical latch itself remains in the extended position. [2]

Electric strikes can be either fail-secure (remain locked when power is lost — the physical latch holds the door closed) or fail-safe (release when power is lost, similar to a maglock). Fail-secure electric strikes are appropriate for interior security doors where preventing unauthorized access during a power failure is the priority. Fail-safe electric strikes are appropriate for egress doors where free exit must be maintained even during power failures.

When to Choose a Maglock: Applications and Limitations

Best applications for maglocks in Austin commercial properties:

Frameless glass doors — the most common application in Austin’s modern commercial office and retail environments. Glass entry doors frequently don’t have traditional door frames compatible with electric strike hardware, and maglocks mount cleanly on the glass door’s top rail and the adjacent frame header.

Interior security doors where the door is held closed by the maglock and the credential controls the release. Conference room entries, server room doors, executive area entries.

Doors where a fail-safe release is explicitly required — fire code egress doors where occupants must always be able to exit regardless of access control system status.

Limitations and code requirements for maglocks:

NFPA 101 Section 7.2.1.9 (Access-Controlled Egress Doors) requires that an access-controlled egress door equipped with an electromagnetic lock release the lock within three seconds when a request-to-exit device is activated, when the fire alarm panel activates, or when a power failure occurs. [3] This three-second release requirement must be engineered into the installation through proper fire alarm interface and REX sensor configuration.

ADA compliance requires that maglocked doors be operable without tight grasping, pinching, or twisting of the wrist. For glass doors with maglocks, this typically means push-paddle hardware on the egress side combined with the REX sensor for lock release — not a traditional pull handle that requires grip force.

Maglocks should not be installed on fire-rated door assemblies as the sole means of keeping the door closed, because they rely on power to maintain closure. A fire-rated door assembly must be able to close and latch under fire conditions — a maglock provides no latching function.

When to Choose an Electric Strike: Applications and Limitations

Best applications for electric strikes in Austin commercial properties:

Doors with traditional frame-and-latch configurations — wood or hollow metal frame doors with standard mortise or cylindrical locksets. The electric strike replaces the existing strike plate without requiring significant frame modification.

Interior security doors where fail-secure operation (remaining locked during power failure) is the priority — storage rooms, server rooms, pharmacy areas, restricted offices.

Doors where the physical latch provides a backup mechanical means of security in addition to the electronic access control function — the door remains physically latched even if the electric strike power fails (in fail-secure configuration).

Limitations and code requirements for electric strikes:

Electric strikes on egress doors must be configured for fail-safe operation (release on power failure) to comply with NFPA 101 free egress requirements for occupied buildings. A fail-secure electric strike on an egress door is a fire code violation.

Electric strike hardware must be listed and compatible with the specific lockset and frame it is installed with. Mismatched combinations — a strike designed for one lockset type installed with a different type — can result in incomplete engagement, inconsistent locking, and hardware damage.

Fire-rated door assemblies require fire-rated electric strike hardware listed for the applicable fire rating. Standard commercial electric strikes may not be appropriate for fire-rated applications.

Fire and Egress Code Compliance in Austin: What the Codes Actually Require

Austin commercial properties are subject to the International Building Code (IBC) and International Fire Code (IFC) as locally adopted, NFPA 101 Life Safety Code, Austin Energy electrical code requirements, and Austin Fire Department enforcement for life safety systems.

The key code requirements for electrically controlled commercial doors in Austin:

Free Egress. NFPA 101 requires that egress doors be operable without the use of a key, tool, or special knowledge or effort from inside the occupied area — meaning any access-controlled egress door must release freely from inside (via push paddle, door contact release, or similar mechanism), regardless of the access control system status. [3]

Fail-Safe Release. Access-controlled egress doors must release automatically upon fire alarm activation. This requires a physical connection between the access control door hardware (maglock power relay or electric strike release) and the fire alarm panel. This wiring must be coordinated between the access control installer and the fire alarm system, and must be verified during commissioning. [3]

Three-Second Release. For maglocks on egress doors, NFPA 101 Section 7.2.1.9 requires that the electromagnetic lock release within three seconds of the activation of a request-to-exit device. This requires proper REX sensor installation and power control relay configuration — not just connection, but tested, verified performance.

Austin Energy Permit Coordination. Electrical work associated with maglock power supplies, electric strike power supplies, and control wiring connected to electrical systems must comply with Austin Energy’s electrical permit requirements. Low-voltage control wiring (door hardware control circuits below 50V) is typically within the low-voltage contractor’s scope, but line-voltage power supply installation must be coordinated with a licensed electrician.

ADA Title III Requirements. Commercial facilities open to the public — storefronts, restaurants, offices with public access — must comply with ADA accessibility requirements for door hardware, including push-pad or push-bar opening mechanisms and door opening force requirements.

Wiring for Compliance: Electrical and Low-Voltage Coordination

One of the most common causes of failed inspections and rework on Austin commercial access control installations is inadequate coordination between the low-voltage access control installer and the electrical contractor responsible for power supply installation.

Here is what the wiring scope for a typical Austin commercial maglock or electric strike installation involves:

Low-voltage scope (Nexlar, licensed low-voltage contractor): Credential reader installation and data cabling, door hardware control wiring (the low-voltage control circuit between the access control panel and the lock hardware), request-to-exit sensor installation and wiring, door position sensor installation and wiring, fire alarm interface relay wiring (low-voltage control circuit from fire alarm panel to lock release), and access control panel installation and configuration.

Electrical contractor scope (licensed electrician): Power supply for the access control panel, power supply for maglocks or electric strike transformer/power supply units (including the line-voltage side of any power supply enclosures), conduit for any wiring that passes through walls or ceilings where conduit is required by the Austin building code.

Coordination requirement: The low-voltage control circuit between the fire alarm panel and the lock release relay must be coordinated between the access control installer, the fire alarm contractor, and the electrical contractor to ensure that the connection is made correctly, the relay is configured for the correct fail-safe response, and the interface is tested during commissioning with the fire alarm panel actively triggered to verify three-second release performance.

Austin commercial projects that skip this coordination — that wire the lock hardware without testing the fire alarm interface, or that rely on the low-voltage contractor to complete work that requires an electrician’s permit — frequently result in Austin Building Inspections findings that require corrective work before a certificate of occupancy or a fire marshal sign-off is issued.

Request-to-Exit Sensors: The Egress Piece Most Installers Get Wrong

A request-to-exit (REX) sensor is an infrared motion detector mounted on the interior (egress) side of an access-controlled door that detects when a person approaches the door from inside and releases the lock, allowing free egress without a credential — meeting the NFPA 101 requirement that egress doors be operable without special knowledge or hardware. [4]

REX sensors are one of the most frequently under-specified and incorrectly installed components in Austin commercial access control projects. Common mistakes:

Incorrect coverage area. A REX sensor must detect occupants approaching the door from the full width of the approach path — not just from the center. A sensor positioned too high, too far to one side, or with an insufficient coverage pattern will allow an occupant to approach the door without triggering the release, requiring them to touch the door or call for help to exit. This is both an operational problem and an NFPA 101 compliance issue.

REX sensor triggering false releases. Sensors positioned too close to the door or with excessive sensitivity may trigger releases when the door swings through the sensor’s coverage area during normal operations, or may trigger continuously in a high-traffic area — keeping the lock released when it should be secured. Coverage pattern and sensitivity must be tuned to the specific door position.

Missing REX sensor on some doors. On a multi-door access control project, it is not uncommon for REX sensors to be specified on most doors but accidentally omitted on one or two. Every access-controlled egress door needs a REX sensor or equivalent egress release mechanism.

Incompatible REX specifications. Some access control panels require a specific REX input signal type (normally open vs. normally closed contact closure). Mismatched REX sensor specifications result in doors that don’t release on approach or that remain in a constant release state.

Nexlar verifies REX sensor coverage, sensitivity, and integration as part of commissioning testing on every Austin commercial installation — and documents the test results as part of the project completion package.

Integrating Commercial Door Hardware with Access Control Platforms

The maglock or electric strike at each door is controlled by the access control panel — which receives the credential signal from the reader and sends the lock release signal to the door hardware based on the access policy. The integration requirements between door hardware and access control panel are specific and must be matched during design.

Power supply matching. Maglocks and electric strikes have specific voltage and current requirements. The access control panel’s lock output relay must be matched to the lock hardware’s electrical requirements — or a separate power supply with relay output must be used.

Fail-safe wiring verification. The fire alarm panel interface — which releases the lock on alarm activation — must be wired into the power supply circuit or relay circuit in a way that guarantees lock release on alarm, regardless of the access control panel’s status. This is typically accomplished through a normally-closed relay in the lock power circuit that opens (cutting power to the maglock or releasing the electric strike) when the fire alarm activates.

Door position sensor monitoring. Door position sensors (magnetic contacts) connected to the access control panel report door open/closed status, enabling held-open alarms and providing event-correlated data about door operations.

Nexlar’s access control systems for Austin commercial properties include complete door hardware specification, power supply design, fire alarm interface coordination, and commissioning documentation as standard components of every commercial installation.

Common Hardware Mistakes on Austin Commercial Doors

Maglock on a fire-rated door without latching hardware. Maglocks provide no mechanical latch. A fire door requires a latch that holds the door closed under fire conditions. Maglock-only on a fire door is a fire code deficiency.

Fail-secure electric strike on an egress door. A fail-secure strike remains locked when power is lost — trapping occupants if the electrical system fails during a fire or other emergency. All egress door strikes must be fail-safe.

No fire alarm interface on access-controlled egress doors. The single most commonly missed compliance item in Austin commercial access control installations. If the fire alarm activates and the door doesn’t release, the installation fails both the fire code and NFPA 101.

Mismatched voltage. A 12V maglock connected to a 24V output will immediately fail (and likely emit smoke). This sounds obvious but occurs in projects where hardware procurement and installation are managed by different parties without proper specification coordination.

Non-fire-rated hardware on fire-rated door assemblies. Same principle as panic hardware on fire doors — every component of a listed fire-rated door assembly must be listed for that rating. Standard commercial maglocks and strikes may not carry the appropriate fire rating for a fire door application.
