The Alarm Lock 9HW607-IC-DBLSIDED Double-Sided Lock Body Assembly is a heavy-duty commercial replacement chassis designed for compatible Alarm Lock Trilogy double-sided electronic cylindrical locksets with Best-style interchangeable-core preparation.

Engineered for use with the Alarm Lock DL5200IC, DL5300IC, and PDL5300IC Series, this replacement body helps restore the mechanical operation of existing double-sided electronic locks without requiring replacement of the entire keypad and lever assembly when the other components remain serviceable.

Unlike standard keyed-cylinder versions, the 9HW607-IC-DBLSIDED is specifically configured for Small Format Interchangeable Core (SFIC) applications, making it suitable for facilities using compatible interchangeable-core keying systems.

The double-sided chassis is designed to work within a complete Trilogy locking system where access is electronically controlled from both sides of the door. When properly assembled with compatible components, the lock body interfaces with the lever, latch, and electronic locking mechanisms to provide normal door operation.

This component is particularly useful for maintaining existing electronic access control installations in commercial buildings, government facilities, educational institutions, healthcare environments, warehouses, and other secured locations.

The interchangeable-core configuration allows facilities using compatible key systems to retain their existing keying arrangement, subject to proper core and hardware compatibility.

This listing is for the replacement double-sided lock body assembly only. Interchangeable cores, complete electronic keypad assemblies, and the finished lockset are not included.

How the Alarm Lock 9HW607-IC-DBLSIDED Works

1. Replacement Chassis Installation

The replacement lock body is installed in the existing compatible Trilogy double-sided cylindrical lock assembly.

2. Mechanical Latch Connection

The body interfaces with the appropriate cylindrical latch and mechanical operating components.

3. Primary-Side Operation

The completed Trilogy lockset contains a primary-side assembly responsible for the designated electronic and mechanical functions.

The primary side provides the operational mechanical key override when correctly equipped.

4. Secondary-Side Operation

The opposite side contains the secondary access control components.

The secondary-side key or control-core arrangement is used for service access and does not provide the same mechanical latch override as the primary side.

5. Electronic Authorization

When a valid keypad code or applicable proximity credential is accepted by the complete lock system, the corresponding authorized lever operation is permitted.

6. Mechanical Keying

Compatible interchangeable cores are installed according to the applicable Alarm Lock instructions.

The primary-side core provides the designated mechanical override function when properly equipped with the approved tailpiece.

7. Door Latching and Operation

When all components are properly installed, the lock body works with the existing latch, levers, and control hardware to provide normal locking and unlocking functions.

Installation Information

The 9HW607-IC-DBLSIDED is designed for replacement within compatible Alarm Lock Trilogy double-sided electronic cylindrical locks.

1. Identify the Existing Lock

Verify that the installed lock is a compatible DL5200IC, DL5300IC, or PDL5300IC model.

2. Confirm Interchangeable-Core Preparation

Check that the existing lock uses the correct Best-style interchangeable-core configuration.

Do not substitute a standard keyed-cylinder chassis for an IC-prepared lock body.

3. Inspect Existing Components

Examine the latch, lever assemblies, interchangeable cores, spindle connections, and electronic components.

4. Remove Existing Hardware

Follow the appropriate manufacturer installation and service instructions to disassemble the existing lock.

Remove the interchangeable cores using the correct control keys and procedures before disassembling the applicable lever assemblies.

5. Install Replacement Chassis

Position the new lock body within the existing cylindrical door preparation.

Ensure correct alignment with the latch and operating components.

6. Reinstall Compatible Hardware

Reassemble the primary and secondary lock components according to the applicable Alarm Lock instructions.

7. Install Interchangeable Cores

Install the compatible IC cores and manufacturer-approved tailpieces where required.

8. Verify Mechanical Operation

Confirm correct lever movement, latch retraction, and primary-side mechanical key override.

9. Verify Electronic Operation

Test authorized keypad and proximity access functions on both sides, where applicable.

10. Verify Egress and Safety

Check that the completed installation meets the building's applicable emergency egress and life safety requirements.

Important Installation and Safety Notes

• Intended for compatible double-sided Trilogy cylindrical locksets.

• Best-style interchangeable-core preparation.

• IC cores are sold separately.

• Not interchangeable with the standard keyed-cylinder version.

• Does not include a complete electronic keypad lockset.

• Only the primary-side mechanical key override operates the latch.

• The secondary-side key arrangement is intended for service access.

• Verify all core and tailpiece requirements before installation.
