Form 4: Fire Detection System Maintenance Certificate — Everything a Business Owner and Building Manager Need to Know

What is Form 4 and why does it exist?

Form 4 of the National Fire and Rescue Authority is an official certificate confirming that the property's fire detection system has been inspected, found sound, and is properly maintained. It is part of the fire documents required to obtain and renew a business license, and is submitted as part of the business licensing process under the Business Licensing Law, 5728-1968.

The reason for its existence is simple and life-saving: a fire detection system that is not properly maintained may fail to operate at the moment of truth. Dusty smoke detectors, expired backup batteries, and a control panel with faults — all of these turn an expensive system into a useless piece of plastic. The form requires periodic inspection by a certified professional, and provides the licensing bodies and the fire service with documented evidence that the system actually works.

Which system the form certifies and how it saves lives

Form 4 addresses a fire detection and alarm system — a system comprising smoke detectors, heat detectors, manual alarm buttons, a central control panel, interfaces to suppression systems, and alarm bells or sirens. The system's role is to identify a fire in its early stages and alert the building's occupants and the fire forces before the fire spreads.

Early detection gives people the critical minutes needed to evacuate safely. In most building fires it is the smoke — not the flames — that is the most dangerous to human life, so an early and reliable alarm is sometimes the difference between an orderly evacuation and a disaster.

Israeli Standard 1220 — what it requires, in plain terms

SI 1220 is the Israeli standard for fire detection and alarm systems, based in part on corresponding European standards. It defines, among other things:

• Types of detectors suited to different spaces (smoke, heat, flame, and more).
• Spatial layout — how many detectors are required per area and the maximum distance between them.
• Control panel requirements — identifying the alert zone, event logging, and interfaces to external parties.
• Ongoing maintenance — functional tests, detector cleaning, backup battery testing, and documentation in a maintenance log.
• Competence of the maintainer — who is authorized to perform the inspection and issue the documentation.

The standard distinguishes between periodic functional tests, performed by an authorized technician during the year, and a comprehensive periodic inspection that includes actually activating components and examining the entire system.

Who must submit Form 4 and when?

The obligation to submit Form 4 applies to any business or property where a fire detection system has been installed — whether by requirement of the fire service, by virtue of building regulations, or according to the guidelines of the local licensing authority. In practice this usually means:

• Hotels, pensions, and lodging houses.
• Shopping centers, markets, and large commercial structures.
• Hospitals, clinics, and nursing homes.
• Educational institutions.
• Warehouses and factories above a certain scale.
• High-rise residential buildings required to have a central detection system.

The form is required mainly in three circumstances: a new business license application, license renewal, and when a fire inspector conducted an inspection and determined that an updated certificate must be provided. House committees in buildings with a central system may also be required to hold such a certificate, for example following a renovation or a change of designation.

Who is authorized to fill out and sign the certificate?

This is one of the topics that generate the most confusion. It is customary to distinguish between two types of signatories:

• An authorized technician or authorized maintenance company — a party that has undergone recognized training and is permitted to perform ongoing maintenance and issue a maintenance certificate. Most routine Form 4 certificates are signed by such parties.
• A registered electrical engineer or fire safety engineer — required mainly for a comprehensive inspection following a change of use or expansion, or when the fire inspector explicitly requires an engineer's certificate.

The critical point: not every security company or electrician may sign Form 4. The certificate must come from a party registered and recognized as authorized to perform fire detection system maintenance. A signature by an unauthorized party may render the form inadmissible and delay the license.

Validity of the certificate and inspection frequency

The validity of a maintenance certificate under SI 1220 is usually one year. However, the standard also requires periodic functional tests during the year, at a frequency derived from the type of system and the character of the property. These tests are documented in the system's maintenance log, and the fire inspector may ask to review it.

It is important to remember: the certificate's expiry date is derived from the date of inspection, not the date the form is submitted. If the inspection was performed in February, the certificate will expire in February of the following year — even if the license renewal falls in a different month.

What does the fire inspector actually check?

During a fire inspection the inspector does not rely on the form alone. They may perform:

• Visual inspection of detectors — physical damage, spray paint, blockage by shelves, or improper distance from the ceiling.
• Review of the maintenance log — to verify that the periodic tests were actually performed and not merely recorded "on paper."
• Activating a detector for testing — sometimes the inspector will actually test at least one detector and expect the panel to respond.
• Checking validity dates — both of Form 4 itself and of components such as the backup batteries.

Common mistakes and oversights — the points worth knowing

• A signature by an unauthorized party. The security supplier who monitors the system is not necessarily authorized to issue a maintenance certificate. Always check the signatory's competence.
• Resubmitting an old form. Copying a form from a previous year with a new date is document forgery, with all the serious implications that entails.
• A change to the system without updating the form. Adding a floor, changing the use of a space, or moving partitions may require re-inspection — and not just a routine renewal.
• Dusty detectors that were not cleaned. An inspector who finds a smoke detector covered in thick dust will not regard the form as a reliable certificate, even if it is new.
• Absence of a maintenance log. The Authority expects to see documentation of every technician visit, not just the comprehensive annual inspection.
• A control panel in mute mode. A panel muted following false alarms and left that way is a serious failure that an inspector will identify immediately.
• Expiry between license renewals. A business license may be granted for several years, but Form 4 is valid for one year — it is easy to forget to renew it in the interim.

Practical tips for the business owner and building manager

• Keep a copy of every Form 4 received — both in the physical property file and as a digital scan.
• Set a calendar reminder about 60 days before the certificate expires — enough time to schedule a technician, fix any deficiencies found, and submit the document.
• Ask the technician to sign the maintenance log on every visit, not just the annual inspection.
• Make sure the maintainer is authorized to perform fire detection system maintenance before signing a maintenance contract.
• If you renovated, update the maintenance company before submitting the form — the system may need expansion.
• Ask the fire inspector on the first visit which additional documents they expect to see beyond Form 4 itself.

How Domera helps track Form 4

The Domera building management platform includes a digital file for the property where you can store Form 4 alongside the other fire approvals, track expiry dates, and receive automatic reminders before the certificate expires. The building-supplier directory lets you save the details of the authorized maintenance company — so all the information is consolidated in one place, and not scattered across emails, binders, and sheets of paper.
