About Detex (Detex Corporation (New Braunfels, TX))
Detex is the industry leader in exit alarm devices — panic hardware with built-in local audible alarms that sound when the door is opened. These aren't building-wide fire alarms (those are separate systems installed by fire alarm contractors); they're door-level devices that siren loudly when someone opens an emergency-only exit, deterring unauthorized use while remaining code-compliant for egress. You've heard them before — the loud electronic alarm when someone pushes the "emergency exit alarm will sound" door at a retail store, school, or warehouse.
Detex is particularly important for Florida retail loss prevention, warehouses, storage facilities, schools, and multi-tenant commercial buildings where emergency exits must remain unlocked for egress but alarmed to deter shoplifting, unauthorized entry, or misuse. Detex integrates cleanly with building fire alarm systems — on fire alarm activation, delayed egress devices release immediately (as required by NFPA 101), and alarm devices can be configured to silence or stay active depending on the facility's emergency protocol.
Key-En-Lock services the full Detex product line across Brevard County. We carry the most common service part — Detex batteries — on the truck, because "my alarm isn't working" is most often just a dead 9V battery that hasn't been replaced in years.

Available Trims & Lever Options
The trim is the outside hardware attached to the exit device — the lever, pull, thumbpiece, or knob that determines how the door opens from the outside when unlocked. Inside remains the panic bar (for code-compliant free egress). Below are the standard trim options available for Detex exit devices:
| Trim Code | Type | Function | Description |
|---|---|---|---|
| Integrated lever | Integrated lever | Key retracts latch | Built-in lever trim — Detex typically ships with integrated lever rather than separate trim kits. |
| Integrated pull | Integrated pull handle | Key retracts latch | Factory pull handle on Advantex and V40 models. |
| Key-reset cyl | Key-reset cylinder | Silences and resets alarm | Specialty cylinder that silences the alarm after an authorized opening. Required on all alarmed Detex devices. |
| Card reader | Card reader integration | Electronic alarm silence | Credential-based alarm silence for authorized egress — bar activation + valid credential = no alarm. |
| EO (alarm only) | Exit only, no outside | Emergency egress only | No outside entry — alarm-only emergency egress. |
| Inside lever (V40) | Inside passage lever | Free egress | Always-free inside lever on V40 variants. |
Available Finishes
Finishes are specified using ANSI/BHMA finish codes. The most common finishes for commercial door hardware in Florida are satin chrome (626), satin stainless (630), and oil-rubbed bronze (613). Most trims can be ordered in any of these finishes:
Common Detex Repairs
- Alarm won't sound when bar is pushed — dead 9V battery (most common), dead internal battery pack, or bad alarm board. Battery replacement is the first check.
- Alarm sounding continuously / false alarms — bar micro-switch failure or stuck contact. On-site switch replacement.
- Delayed egress not releasing after 15 seconds — control board failure or miscalibrated timer. Board replacement or field recalibration.
- Fire alarm release not triggering — wiring issue between Detex and fire alarm control panel. Verification and rewire.
- Key-reset cylinder won't reset the alarm — worn cylinder, bent key, or internal cam wear. Cylinder replacement or rekey.
- Annual battery replacement — battery-powered Detex devices must be serviced yearly. Dead batteries are the #1 cause of "my alarm isn't working" calls.
- EAX-500/2500 not arming — power supply or internal relay check. Verification of wiring to monitored door contact.
- ECL-230 bar not returning — internal return spring or cam wear. On-site rebuild.
Electrification & Access Control Integration
Adding electric latch retraction (EL) or other electrification options turns mechanical Detex devices into access-control-capable entrances. Exit remains code-compliant free egress from the inside, but outside entry becomes scheduled, credentialed, or automated. See our full electrification overview on the main panic hardware page.
- Detex is inherently electrified — all alarmed and delayed egress Detex devices include electronic components. The question is integration depth, not whether to electrify.
- Access control integration — Tie alarm silence to a card-reader authorized exit, so credentialed staff can exit without triggering the alarm.
- Fire alarm release wiring — Delayed egress devices MUST release on fire alarm under NFPA 101. This wiring is non-negotiable for code compliance.
- Centralized alarm monitoring — Wire Detex alarm events into building security panels or access control dashboards for audit logging.
- Remote reset — EAX-2500 and 10 Series can be configured for remote reset from a security desk or access control system.
- Power supply considerations — Hard-wired Detex variants eliminate the annual battery replacement maintenance task. For buildings with many Detex devices, hard-wired is often the better long-term choice.
Fire-Rated Options & Code Compliance
- Detex 10 Series Delayed Egress: Florida-legal under NFPA 101 with proper installation, signage ("PUSH UNTIL ALARM SOUNDS — DOOR CAN BE OPENED IN 15 SECONDS"), and fire alarm integration.
- Delayed egress MUST release immediately on fire alarm activation — hardwired tie to the fire alarm panel is code-required, not optional.
- Delayed egress MUST release on loss of power — confirmed on-site during every install.
- Maximum delay: 15 seconds after bar is pressed, with audible countdown.
- AHJ (Authority Having Jurisdiction — usually the local fire marshal) must approve delayed egress for the specific occupancy. We coordinate with Brevard County fire inspectors during install.
- Exit alarm devices (non-delayed) must not impede egress — the door must open immediately when pushed; only the alarm sounds.
All Detex fire-rated exit devices must be installed and maintained in accordance with NFPA 101 and the Florida Building Code. We install inspection-ready — meaning it passes the fire marshal the first time.
Detex FAQ
My Detex exit alarm won't stop beeping — what's wrong?
Two common failures. First, the 9V internal battery is dead or weak — these should be replaced annually but often aren't. Second, the bar micro-switch that detects pushes has failed or is stuck, sending a continuous "bar pressed" signal. Both are quick on-site repairs. If it's a delayed egress Detex (the 15-second countdown type), a stuck control board or sensor is also possible. We carry replacement parts for all Detex Advantex, ECL-230, and 10 Series devices on the truck.
Is delayed egress legal in Florida?
Yes, with specific conditions under NFPA 101 and the Florida Building Code. The door must release automatically on fire alarm activation, release automatically on loss of power, release after a maximum 15-second delay when the bar is pressed, be clearly signed, and only be used in occupancies where the AHJ (local fire marshal) has approved delayed egress. Detex 10 Series meets all these requirements when installed correctly. The Allegion-brand equivalent is Von Duprin CHEXIT (CX option on 98/99/33A/35A chassis) — same code compliance, different brand ecosystem. For buildings already running Von Duprin, CHEXIT keeps parts consistency; for standalone or mixed-brand buildings, Detex often fits cleaner. We handle both and coordinate with your local fire marshal for approval.
How often should Detex batteries be replaced?
Annually at minimum. Battery-powered Detex devices use standard 9V alkaline batteries that drift downward over time even without alarm activation. A dead battery won't sound the alarm when someone opens the emergency exit — defeating the entire purpose of the device. For buildings with multiple Detex devices, we offer scheduled annual battery service as part of a maintenance contract.
Can I silence a Detex alarm without the key?
Not by design. The key-reset cylinder is the only intended way to silence an Advantex, ECL-230, or 10 Series alarm after activation. This is a feature, not a bug — it prevents unauthorized people from disabling the alarm. If you've lost your key-reset key, we can rekey the device to a new key on-site without replacing the whole unit.
Does Detex make real fire alarms?
No, and this is an important distinction. Detex makes exit alarm devices — door-level hardware with local audible alarms. Building-wide fire alarm systems (smoke detectors, pull stations, horns/strobes, FACP panels) are installed by licensed fire alarm contractors under a separate Florida EF license. Detex devices integrate WITH fire alarm systems — delayed egress releases on fire alarm, for example — but they are not themselves fire alarms. For building fire alarm work, you need a licensed fire alarm contractor.
Can Detex replace a regular panic bar or do I need both?
Detex replaces the panic bar entirely — you don't need both. An Advantex or ECL-230 is a complete exit device (panic bar) with the alarm built in. For existing doors where you want to add an alarm without replacing the panic hardware, the EAX-500 or EAX-2500 mounts alongside the existing device as a retrofit. The Von Duprin equivalents are the Von Duprin 2670 GUARD-X (standalone alarmed exit device, comparable to ECL-230) and the Von Duprin ALK Alarm Kit (retrofit accessory, comparable to EAX-500). All of these approaches meet code.
We've got 15+ Detex devices across our buildings — do you do scheduled maintenance?
Yes. For buildings with multiple Detex devices, we offer annual maintenance contracts that include battery replacement, function testing, key-reset cylinder verification, fire alarm integration check, and minor repairs. One visit per year keeps the whole facility code-compliant and catches failures before a fire marshal inspection flags them.
