Edwards EST3 to EST4 Upgrade on Long Island
EST3 Support Ends December 31, 2026. Plan Ahead While Evaluating Your Options.
Plan Your EST3 Upgrade With Confidence
Edwards has announced the end of EST3 manufacturer service support and replacement-parts availability effective December 31, 2026. That announcement does not automatically require every existing EST3 system to be upgraded. However, replacement-parts limitations can increase the risk of prolonged outages and corrective work following an equipment failure.
New York Fire Detection & Service helps commercial building owners, property managers, and facility teams in Long Island evaluate risks, explore modernization options, and plan an appropriate EST4 upgrade.
An Upgrade May Retain Much of Your Existing System
Many existing field devices and other system components may be retained during modernization, potentially reducing project cost and disruption. What can remain depends on compatibility, configuration, and existing conditions; certain equipment may require replacement. NY Fire evaluates the installation before developing the proposed conversion scope.
Nassau & Suffolk County Approval Considerations
Fire alarm modification and replacement requirements on Long Island vary by municipality, fire district, and authority having jurisdiction. Depending on the location and project scope, modernization may involve engineering documentation, local permits, fire marshal review, testing, or acceptance procedures. NY Fire identifies the applicable requirements and incorporates them into the project plan.

Frequently Asked Questions
Is an EST3-to-EST4 upgrade mandatory?
Edwards’ discontinuation announcement does not independently require immediate replacement of every functioning EST3 system. Building-specific conditions and applicable requirements may affect the appropriate course of action.
Can we continue operating our EST3 system after December 31, 2026?
An existing system may remain operational, but loss of manufacturer support and replacement-parts availability can complicate repairs after a critical failure.
Will every device need to be replaced?
Many existing devices and components may be retained, subject to a compatibility assessment. NY Fire can identify the options applicable to your installation.
Are approval requirements the same throughout Long Island?
No. Requirements vary by jurisdiction and project scope. NY Fire can identify the applicable process as part of the evaluation.
