Liftmaster K94-37467, OMNI SIREN

The LiftMaster K94-37467 is an Omni siren replacement kit used on compatible LiftMaster gate operator and perimeter access control systems. It restores the audible warning output used by the operator control system for alerts, movement warnings, or fault-related conditions depending on the installed equipment.

Unlike a basic aftermarket buzzer, this is a LiftMaster service part intended to match specific Omni-style control applications. Public compatibility listings are broad, usually stating use with various LiftMaster gate operators and perimeter access solutions. For that reason, the correct way to order this item is by matching the original part number, the operator manual, and the replacement parts diagram.

Technician Note

If the existing siren is sounding continuously or repeatedly, document the diagnostic condition before replacement. A bad siren is possible, but the control system may also be reporting a valid operator fault.

Before Ordering

• Match K94-37467 to the operator parts diagram.
• Compare the old siren connector and mounting style.
• Confirm the system uses an Omni siren, not a different alarm-and-harness kit.
• Check for water damage, cut wires, or failed connector pins.
• Troubleshoot active alarm or safety faults before replacing the siren.

Professional Advisory

A gate siren or warning device should never be removed as a workaround. If the alarm is active, the operator should be inspected by a qualified gate technician before being placed back into normal use.

Important Ordering Warnings

• Broad compatibility does not mean universal fitment.
• Do not replace a harnessed alarm with this siren unless the diagram confirms it.
• Do not silence or bypass warning devices to clear a nuisance alarm.
• Verify the operator control platform before ordering.

Product Questions and Answers

What is the K94-37467 used for?

It is an Omni siren replacement kit for compatible LiftMaster gate operators and perimeter access solutions.

Is there a full model list for this siren?

Public listings generally describe it as fitting various LiftMaster gate operators and perimeter access systems, so the safest approach is to verify it against the installed operator parts diagram.

Is this the same as the K94-37461 alarm and harness?

No. K94-37461 is a separate alarm and harness kit commonly listed for SL3000 and CSW200 applications. K94-37467 is an Omni siren kit.

Can I install this if my current siren keeps sounding?

Only after the operator fault has been diagnosed. A continuously sounding siren may be reporting an entrapment, obstruction, safety, or control problem.

Does this change how the gate operates?

No. It replaces the audible siren/warning component. It should not be used to alter, bypass, or defeat any safety function.
