The Alarm Lock 730X28 Single Door Strike is a commercial-grade replacement keeper designed for use with compatible Alarm Lock alarmed panic exit devices. Featuring a satin aluminum finish, single-door configuration, and manufacturer-specific mounting design, this accessory provides a replacement receiving point for the locking mechanism of an Alarm Lock exit security system.

Part of the Alarm Lock 730 Series, the 730X28 is designed primarily for the Alarm Lock 250, 700, and 80 Series alarmed exit devices.

The keeper works with the compatible locking assembly to help maintain proper door engagement when the door is closed and the exit hardware is secured. Correct alignment between the strike and locking mechanism is essential for reliable door operation.

The 730X28 is an excellent replacement option for existing commercial openings where the original keeper is damaged, missing, worn, or requires replacement during door hardware servicing.

Finished in 628 / US28 Satin Aluminum Clear Anodized, the strike complements compatible Alarm Lock exit devices and commercial aluminum architectural hardware.

This product is the single-door keeper only. It does not include the complete exit device, locking assembly, push bar, alarm, or electrical components.

Technical Specifications

How the Alarm Lock 730X28 Works

1. Door Closing

As the commercial door closes, the locking portion of the compatible Alarm Lock exit device approaches the keeper mounted at the frame.

2. Locking Engagement

The locking mechanism engages the correctly positioned strike, helping secure the door in its closed position.

3. Normal Exit Operation

When the installed exit device is properly activated, its locking mechanism releases to permit the door to open.

4. Alarm Operation

If the installed exit device includes an audible alarm, the alarm functions are controlled by that device. The 730X28 itself contains no electronic alarm components.

5. Door Relatching

When the door closes again, the locking mechanism engages the strike according to the normal operation of the compatible exit hardware.

Replacement and Maintenance Applications

The Alarm Lock 730X28 is suitable for replacing an existing compatible single-door strike when:

• The original strike has been damaged.

• The keeper is missing from an existing door installation.

• Locking engagement is unreliable because the existing keeper is worn or damaged.

• Door hardware is being refurbished.

• An existing Alarm Lock 250, 700, or 80 Series installation requires a replacement keeper.

Before replacing the strike, inspect the door alignment, hinges, locking mechanism, frame condition, and mounting surfaces.

A properly installed replacement strike can help restore normal locking engagement, but it will not correct problems caused by a damaged lock assembly or significant door misalignment.
