The Detex Product Lines: What Each One Is and Does
ECL Series
Complete panic exit hardware with battery alarm. The ECL-230D is a push-bar deadbolt device with 1-inch throw, 100dB alarm, and photo-luminescent sign. Meets life safety panic requirements. Used on secondary exits, back doors, and restricted commercial egress points. The ECL-230X is the ultra-rugged break-in prevention version with hardened deadbolt.
EAX Series
Battery-powered surface alarm, not a panic device. Mounts on door or wall and uses magnetic contact to trigger 100dB alarm when door is opened without key authorization. The EAX-500 is the standard model. The EAX-500W is the weatherized outdoor version. The EAX-2500 is the flush-mount version. No push bar, no deadbolt. Adds alarm monitoring to existing hardware.
ADVANTEX
Premium exit device line for schools, hospitals, airports, retail, and other high-abuse environments. Available in rim (10 Series), surface VR (20 Series), mortise (30 Series), narrow stile rim (40 Series), and concealed VR (60 Series). Stainless steel and vapor deposition finishes. Widest electrified option range of any Detex exit device. Custom lengths 24 to 48 inches. 3-hour UL fire rating on steel doors.
AO19 Series
Not an alarm or exit device. Automatic door opener that mounts in the door header and opens and closes the door on a push button or access control signal. Meets ANSI/BHMA A156.19. ADA compliant. AO19-1 for single doors, AO19-2 for double doors, AO19-3 for double egress applications. 115VAC, obstruction reversal, ON/OFF/HOLD switch. Used in healthcare, commercial, and accessibility-required applications.
Value Series
The Detex V40xNS is a narrow stile rim exit device for standard commercial applications where ADVANTEX-level construction is not required. Available in standard configurations and finishes. Lower price point than ADVANTEX but still meeting ANSI Grade 1 requirements for panic hardware.
90 Series
The Detex 90 Series covers surface-mounted alarm products including door prop alarms. The EAX-300 Series monitors doors that may be used for egress but must not be held open, with adjustable open-time detection from 1 second to 4 minutes. The EAX-411SK is an AC-powered door prop alarm for controlled-access doors. Used where monitoring door-prop violations is the primary concern rather than unauthorized egress.
What Is the Detex ECL-230D and How Does It Work
The ECL-230D is the most widely misidentified product in the Detex line. It is not simply an alarm that gets added to a door. It is a complete panic exit control lock: a deadbolt with a push bar that meets life safety code requirements for panic hardware, combined with a battery-powered 100dB alarm system in a single unit.
When the deadbolt is in the locked position and the push bar is pressed, the bolt retracts for emergency egress and the alarm sounds simultaneously. The alarm can only be reset with a control key. The locking and unlocking of the deadbolt automatically arms and disarms the alarm respectively. This is the fundamental distinction from the EAX-500: pressing the ECL push bar both unlocks the door for egress and sounds the alarm. The EAX-500 only sounds an alarm; it does not control any locking mechanism.
ECL-230D Physical Specifications
The ECL-230D fits wood, hollow metal, and aluminum doors from 1-3/4 to 2-1/4 inches thick. The minimum standard door width is 20 inches. The design is non-handed, so the same unit installs on left-hand or right-hand doors. The attack-resistant design withstands over 2,200 pounds of outside pull force. The 1-inch throw deadbolt is saw-resistant. The lock body is made from corrosion-resistant alloy. The photo-luminescent sign absorbs ambient light and glows in the dark when lighting fails, meeting egress marking requirements without battery backup lighting.
The ECL-230D accepts 5-pin through 7-pin standard and interchangeable core rim cylinders. The IKC (Inside Key Control) cylinder is the ECL-445K. The OKC (Outside Key Control) uses rim cylinders. The cover lock is the mechanism that holds the cover assembly to the backplate and requires a separate cover key to access the battery compartment.
ECL-230D vs ECL-230X: Choosing the Right Version
The ECL-230X is the higher-security version of the ECL-230D. The key differences are a hardened deadbolt for break-in prevention and inclusion of the photo-luminescent sign as a standard component. Both versions produce a 100dB alarm and meet the same life safety code requirements. For most commercial secondary exit applications, the ECL-230D is the correct specification. For back doors on high-theft-risk retail environments, warehouses, and facilities with documented forced entry attempts, the ECL-230X provides additional resistance without changing the operating interface.
Detex EAX-500: Battery Door Alarm Parts and Configuration
The EAX-500 is a surface-mounted battery alarm designed for doors that need an audible deterrent without replacing the existing door hardware. It mounts on the door face or adjacent wall and uses a magnetic contact pair (one half on the door, one half on the frame) to detect door opening. When the door opens and breaks the magnetic contact, the piezo horn sounds at approximately 100dB.
EAX-500 Cylinder Configuration
The EAX-500 comes standard without a cylinder. Key control is optional:
| Option | Part | Function | Location |
|---|---|---|---|
| Inside key control | MC65 | Mortise cylinder, 1-1/8 inch, Schlage C keyway, 6-pin | Bottom of EAX-500 unit (inside face) |
| Outside key control | RC65 | Rim cylinder for outside face | Outside face of door |
| Interchangeable core | IC7 | 7-pin IC housing, compatible with most standard 7-pin IC format cores | Pre-installed at factory, field core insertable |
| Cover lock key kit | ECL-405-KIT | Cover lock key kit for covers on ECL and EAX Series | Cover assembly on both ECL and EAX devices |
The patented cam assembly inside the EAX-500 automatically adjusts for different cylinder sizes without requiring spacers. This is a genuine engineering advantage over competitor alarms where spacers must be sourced separately for non-standard cylinder lengths. The EAX-500's cam system accepts any standard mortise cylinder within the common range without modification.
EAX-500 Battery and Operation
The EAX-500 runs on a 9VDC battery. Low battery is indicated by an LED visual alert. The alarm can only be silenced by the proper control key. The extended bypass feature is standard: when the door is legitimately propped open (during a delivery or loading), the alarm remains bypassed and automatically rearms when the door closes. This prevents the nuisance alarm scenario where a propped door on a loading dock triggers continuous alarm until someone manually resets it.
The intelligent circuit automatically senses the magnet location on the door and sets the correct handing for the unit. This means the same EAX-500 unit installs correctly regardless of whether the door opens left or right, without any configuration switch adjustment. This self-handing feature is a field installation advantage that competitors' alarms do not universally offer.
EAX-500W: The Weatherized Version
The EAX-500W is the weatherized version for outdoor applications including exterior secondary exits, gate alarms, and doors exposed to direct weather. The weather-resistant housing adds moisture protection without changing the operational interface. All cylinder options available on the standard EAX-500 are available on the EAX-500W. For any Detex door alarm installation on a door exposed to direct precipitation or sustained humidity, always specify the EAX-500W rather than the standard EAX-500.

Battery Replacement Procedure: ECL-230D and EAX-500
Both the ECL-230D and EAX-500 use 9-volt batteries accessed through the cover assembly. The procedure differs slightly between the two but follows the same sequence.
ECL-230D Battery Access
To access the ECL-230D battery: insert the cover key into the cover lock and turn counterclockwise until the cover releases. Swing the cover away from the backplate. The 9-volt battery is visible and accessible. Confirm battery voltage is a minimum of 7 volts if any doubt exists about the current battery condition. Replace with a fresh 9-volt battery, reconnect the battery terminal, and confirm all wiring connections are intact before closing the cover. Swing the cover back to the backplate and re-engage the cover lock. Test alarm function by pressing the push bar with the IKC in the locked position. The alarm should sound immediately.
EAX-500 Battery Access
The EAX-500 cover lock uses the cam lock at the top of the unit for cover access. Insert the cover key into the cam lock and release the cover. Replace the 9-volt battery and confirm LED arming indicators function on cover reinstallation. The EAX-500 includes LED visual and audible arming indicators that confirm correct operation after battery replacement. If the LED indicators do not respond correctly after a fresh battery installation, check the battery terminal connection and confirm the magnetic contact sensor is properly positioned before concluding the board has failed.
Detex ADVANTEX Exit Devices: Heavy-Duty Series Guide
The ADVANTEX line is Detex's response to high-abuse commercial applications where standard exit devices suffer accelerated wear. Schools, hospitals, airports, corrections, and retail environments with high daily cycle counts benefit from the ADVANTEX construction: stainless steel, vapor deposition finishes, and the widest electrified option set in the Detex lineup.
ADVANTEX Series by Configuration
| Series | Configuration | Stile | Application |
|---|---|---|---|
| 10 Series | Rim exit device | Wide (4-1/2 inch minimum) | Heavy-duty single and double doors with mullion; highest use interior and exterior egress |
| 20 Series | Surface vertical rod | Wide | Heavy-duty doors without mullion; two-point latching on single doors |
| 30 Series | Mortise exit device | Wide (4-1/2 minimum) | Maximum security and durability with mortise lock body; high-security perimeter doors |
| 40 Series | Narrow stile rim | Narrow (aluminum storefront) | High-use aluminum storefront entries requiring narrow stile panic hardware |
| 60 Series | Concealed vertical rod | Wide | Heavy-duty doors requiring clean exterior face without visible rod hardware |
ADVANTEX Electrified Options
Detex markets the ADVANTEX as having the most comprehensive electrified option set of any exit device in the industry. Available options include electric latch retraction (EL), electric integration (EI), alarm exit (EA), electric bridge (EB), delayed egress (EE), and electric latch monitoring. The EI option connects the exit device to building automation systems, access control panels, and security monitoring platforms, making the ADVANTEX appropriate for high-security environments that require centralized door status reporting.
Fire-rated ADVANTEX devices support 3-hour UL listing on steel doors. The F prefix designates fire-rated versions (for example, F6001 for the 60 Series fire version). Custom lengths from 24 to 48 inches are available. Devices shorter than 30 inches have restrictions on which electrified options are available; always confirm electrified option availability against the device length before specifying.
ADVANTEX Cylinder and Trim Accessories
ADVANTEX devices are ordered without cylinders as standard. Cylinders (C65) or interchangeable core housings (IC7) are pre-installed at the Detex factory when specified at order time. Knurling (KN), antimicrobial finish (AM), and lever switch (LS) options add to the base price. Lever trims for ADVANTEX are specified by function: key retracts latch (C), night latch (NL), dummy trim (DT), and blank escutcheon (BE). Lever trim handing must be specified (RHR or LHR) unless ordering exit-only configurations.
Detex AO19 Automatic Door Operator: What It Is and What Fails
The AO19 is categorically different from every other Detex product. It is not an alarm and it is not an exit device. It is a low-energy automatic door opener that mounts in the door header and powers the door open and closed using a motor-driven mechanism. Understanding what it is prevents it from being ordered to solve an alarm or exit hardware problem.
The AO19 is used on accessibility routes in commercial buildings where ADA requires hands-free door access: healthcare facility corridors, accessible restroom entries, building main entries on accessible routes, and any interior door on a required accessible path where manual door operation would present a barrier for mobility-impaired users.
AO19 Configurations: Single, Double, and Double Egress
The AO19-1 serves single doors. The AO19-2 serves double doors where both leaves open together on a single signal. The AO19-3 serves double egress applications where both doors open away from each other for bidirectional traffic. Each configuration requires separate operators for each leaf. The AO19-2 requires cable synchronization between the two operators for coordinated operation on double door pairs.
AO19 Electrical Requirements and Features
The AO19 runs on 115VAC from a standard outlet. The power source plugs into the header unit. A 3-way low-voltage ON/OFF/HOLD switch controls service and operational modes without requiring line voltage access. The obstruction reversal feature stops the door during a closing cycle and re-activates to open if an obstruction is sensed before the door reaches the latch position. This is the safety interlock that prevents the door from closing on a person or object in the opening.
The AO19 connects to existing access control systems, locking hardware, and building computer signals. A credential read or a wall-mounted push button activation signal triggers the operator to open the door. The controller module inside the operator can be adjusted for opening speed, hold-open time, and closing speed without special tools. Parts for the AO19 include the cover (aluminum or bronze finish), cable sync for twin AO19 UDC 1000 installations (part 104707), and motor/gearbox assemblies documented in the push and pull repair manuals available from Detex.
Detex vs Von Duprin Guard-X: Exit Alarm Comparison
SecurityParts.com carries both Detex and Von Duprin exit alarm products. They serve similar applications but with different design philosophies that affect which one is correct for a specific opening.
The Von Duprin Guard-X 2670 is a single-point rim exit alarm device that is the Von Duprin equivalent of the Detex ECL-230D. Both are battery-alarmed push-bar deadbolt devices meeting panic hardware requirements. The Guard-X uses a Von Duprin cylinder ecosystem while the ECL-230D uses its own IKC cylinder system with the ECL-445K. Facilities that have standardized on Von Duprin cylinders throughout a building may prefer the Guard-X to maintain key system continuity. Facilities that have standardized on Detex hardware or Schlage C keyway cylinders find the ECL series integrates more cleanly into their existing key schedule.

How to Order the Correct Detex Part
Three pieces of information are required before any Detex parts order.
1. Product line (ECL, EAX, ADVANTEX, AO19, Value Series, 90 Series): Visible from the product label on the device. The full model number is on a label on the back plate or side of the unit. For ECL-230D, the model number confirms whether the standard or X (hardened deadbolt) version is installed.
2. Part type (cylinder, cover lock, cam bridge, magnet, cover assembly): Identifying which component has failed determines whether the order is the ECL-445K cylinder, the ECL-1576-15 cam bridge assembly, the ECL-405-KIT cover lock key kit, or the 102665 magnet kit.
3. Cylinder format (standard 5-7 pin, or IC): Confirm whether the installation uses standard conventional cylinders or IC format cores before ordering any replacement cylinder. The IC7 housing is required for IC installations, and the correct IC core must be sourced separately to insert into the IC7 housing.

Why Choose Security Parts for Detex Parts
IKC vs OKC vs cover key documentation, battery life facts, ADVANTEX electrified option guidance, and same-day shipping on stocked components.
Three-Key Documentation
We document the IKC, OKC, and cover key as three distinct key systems on the ECL-230D. Confusion between these generates most ECL service calls. We resolve this before the order is placed.
Battery Maintenance Facts
We document that annual 9-volt battery replacement eliminates 80%+ of ECL and EAX alarm failure calls. A fresh battery costs pennies compared to a service call. We say this directly.
AO19 Correct Identification
We document that the AO19 is an automatic door operator, not an alarm or exit device. This prevents AO19 parts from being ordered for alarm or exit device problems.
Same-Day Shipping
Most Detex ECL, EAX, and ADVANTEX parts ship same day from US warehouses. Call 845-935-0301 or use the contact page for parts identification support.
What Makes Security Parts Different for Detex Parts
- We document the ECL-405-KIT cover lock key kit as the part that provides battery access when the cover key is lost. Most facilities discover the cover key is missing only when the battery dies. This part and its purpose is undocumented at most parts supplier sites.
- We document the EAX-500 extended bypass feature that keeps the alarm from triggering when a door is legitimately propped open. This feature prevents the most common nuisance alarm complaint on EAX-500 installations near loading docks.
- We document the EAX-500 self-handing intelligent circuit as a genuine installation advantage over competitor alarms. Most parts suppliers describe the EAX-500 specifications without explaining why the self-handing feature matters for field installation.
- We document that ADVANTEX devices shorter than 30 inches have electrified option restrictions. Specifiers who do not know this order incompatible EL or EA options for short-length devices and receive field mismatches.
- We carry Detex parts alongside Falcon and Von Duprin exit device parts, LCN door closer parts, Schlage cylindrical lock parts, and mortise lock parts for complete building hardware service in one order.
- Free shipping on orders over $450. Same-day shipping on stocked parts from US warehouses. 30-plus years of commercial door hardware experience.

Frequently Asked Questions About Detex Parts
What is the difference between the Detex ECL-230D and EAX-500?
The ECL-230D is a complete panic exit control lock with a 1-inch deadbolt, push bar, and 100dB alarm that meets life safety code. Pressing the bar retracts the bolt for emergency egress and sounds the alarm. The EAX-500 is a surface-mounted battery alarm with no deadbolt and no push bar. It mounts on the door face and sounds when the magnetic contact is broken by door opening. The ECL-230D replaces the door hardware. The EAX-500 adds alarm monitoring to existing hardware without replacing it.
What battery does the Detex ECL-230D use and how long does it last?
A 9-volt battery. Under normal conditions of 1 to 2 alarm activations per day, battery life is 1 to 3 years. The battery is accessed by opening the cover with the cover key. A minimum voltage of 7 volts is required. Annual replacement as part of routine inspection is recommended. Most ECL alarm failure calls are resolved by replacing a battery that reads low on a meter but still above minimum voltage.
What cylinder does the Detex EAX-500 use and how is key control configured?
Cylinders are not included with the standard EAX-500. For inside key control, the MC65 mortise cylinder (1-1/8 inch, Schlage C keyway, 6-pin) mounts in the bottom of the unit. For outside key control, the RC65 rim cylinder is required. The IC7 7-pin interchangeable core housing is available for IC key systems. The ECL-405-KIT provides cover lock key replacement for both ECL and EAX Series.
What is the Detex ADVANTEX exit device and where is it used?
ADVANTEX is Detex's super-heavy-duty exit device line for high-use, high-abuse environments including schools, hospitals, airports, retail, and corrections. Available in rim (10 Series), surface VR (20 Series), mortise (30 Series), narrow stile rim (40 Series), and concealed VR (60 Series). Stainless steel and vapor deposition finishes. Custom lengths 24 to 48 inches. 3-hour UL fire rating on steel doors. Widest electrified option range of any Detex exit device.
What is the Detex AO19 and what does it do?
The AO19 is a low-energy automatic door operator that mounts in the door header and opens and closes the door automatically on a push button or access control signal. It is not an alarm or exit device. It meets ANSI/BHMA A156.19 and provides ADA-compliant hands-free access. AO19-1 for single doors, AO19-2 for double doors, AO19-3 for double egress. Runs on 115VAC with obstruction reversal and ON/OFF/HOLD service switch.
What is the Detex ECL-445K and what does it replace?
The ECL-445K is the IKC lock cylinder replacement for the ECL-230D exit control lock. It controls the deadbolt throw from inside. Order ECL-445K-7 for the 7-pin version. When the cylinder is difficult to turn, stiff, or the IKC key no longer operates the deadbolt, the ECL-445K is the correct replacement. The ECL-1576-15 is the cam bridge assembly and lock cylinder housing, needed when the housing itself is damaged rather than just the cylinder plug.
