Additional Product Specifications and Ordering Guidance

Electric Door Locking and Release Requirements

Electrified strikes and electromagnetic locks integrate with the building's access and emergency-exit design. Verify the exact host latch/exit device, frame geometry and lock release function rather than selecting on holding force or voltage range alone.

Product SKU: DTX-DS-24.

Hardware Schedule and Ordering Checklist

• Match the specified latch, rim device, magnetic armature or strike template and the actual door handing and frame preparation.
• Check supply voltage/current and electrical switching requirements from the exact manufacturer's installation sheet.
• Coordinate required fire-alarm inputs, request-to-exit means, permitted power-fail response and local egress compliance.
• Review any separate mounting brackets, faceplates, wiring transfers and monitoring contacts needed for a complete installation.
• Where equipped with electrical or alarm functions, confirm required external power, control/reset provisions and emergency behavior before installation.

Installation and Acceptance Checks

Verify mechanical engagement, authorized electric release, correct power-loss response and free egress throughout the door operating cycle.

Factory Package Scope

The specified lock or electric strike, not the complete access-control system. Preserve and review the original detailed specifications below for the particular Detex model.

The electric strike allows a compatible access control system to release the secured opening electronically while the interior panic exit device continues to provide mechanical emergency egress.

Designed for surface mounting on compatible door frames, the DS-24 accommodates a variety of frame configurations and cutouts.

Its one-piece locking mechanism with a single solenoid has been tested to withstand more than 1,500 pounds of holding force, providing dependable security for demanding commercial applications.

The built-in electronics automatically accommodate 11–28VDC input and include surge and kickback protection.

A concealed infrared latchbolt sensor detects the presence of the rim exit device's Pullman-style latchbolt without a mechanical contact switch. The sensor provides Normally Open and Normally Closed monitoring contacts for integration with compatible access control panels, alarms, and building security systems.

The DS-24 includes 1/8-inch and 1/4-inch steel alignment spacers to help position the strike correctly with Detex Advantex and Value Series rim latchbolts.

Finished in US32D / 630 Brushed Stainless Steel, the DS-24 coordinates with commercial stainless steel exit devices and architectural door hardware.

The product carries a UL10C fire-rated listing, subject to the approved installation configuration and complete door assembly.

Ideal for commercial offices, hospitals, schools, warehouses, government buildings, and secured institutional entrances, the Detex DS-24 provides a durable solution for electronic access control with rim panic hardware.

Important: The DS-24 is the standard electric strike. For installations exposed to rain or outdoor conditions, select the separately designated Detex DS-24W Weatherized Electric Strike.

How the Detex DS-24 Electric Strike Works

1. Door Secured

The rim exit device's latchbolt engages the electric strike when the door is closed.

2. Access Credential Presented

An authorized user presents a credential to a connected reader, keypad, or access control system.

3. Access Control Signal

The controller sends the appropriate electrical signal to the DS-24.

4. Strike Release

The electric strike changes to its released condition according to its configured fail-safe or fail-secure function.

5. Authorized Entry

The user opens the door without needing to operate the interior panic pushbar.

6. Secure Return

After the access control release interval, the strike returns to its designated secured condition.

7. Latchbolt Monitoring

The integrated infrared sensor detects latchbolt presence and communicates the corresponding status through its monitoring contacts.

8. Emergency Egress

The compatible interior rim exit device continues to provide mechanical emergency egress independently of the strike's exterior access-control operation.

Compatible Detex Exit Devices

The DS-24 is designed for compatible rim exit device configurations in the following product families:

Step 1 – Verify Exit Device Compatibility

Confirm that the existing Detex rim exit device uses an approved latchbolt configuration for the DS-24.

Step 2 – Verify Frame Conditions

Inspect the door frame, available mounting surface, door alignment, and reinforcement.

Step 3 – Determine Locking Mode

Select Fail Safe or Fail Secure according to the approved access control and life-safety requirements.

Step 4 – Verify Electrical Power

Confirm the regulated DC supply and available current meet the strike's requirements.

Step 5 – Position the Electric Strike

Use the appropriate installation template to align the strike with the rim latchbolt.

Step 6 – Install Spacers

Use the supplied 1/8" and 1/4" spacers as required for proper alignment.

Step 7 – Secure the Strike

Mount the strike using the manufacturer-approved anchoring arrangement and fasteners.

Step 8 – Connect Electrical Wiring

Connect the strike to the appropriate access control release circuit.

Step 9 – Connect Latchbolt Monitoring

If monitoring is required, connect the infrared sensor's NO/NC outputs to a compatible monitoring input.

Step 10 – Test Complete Operation

Verify:

• Correct fail-safe or fail-secure behavior.

• Reliable electronic strike release.

• Proper latchbolt engagement.

• Accurate latchbolt monitoring.

• Automatic relatching after the door closes.

• Unrestricted mechanical emergency egress.

• Applicable fire-door and access control requirements.

Important Installation and Safety Notes

• Use a DC power supply matching the manufacturer's electrical specifications.

• Do not apply line voltage directly to the strike.

• The latchbolt sensor requires its own specified DC power connection.
