In Singapore, fire alarm approval is not a single permit. It is a sequence of three regulatory steps administered by the Singapore Civil Defence Force (SCDF): approval of plans before any works begin, inspection and certification once the system is installed, and periodic renewal of the Fire Certificate for buildings that fall within the scheme. A building owner, developer or contractor who treats these as one transaction typically discovers the gap at the point where occupation is blocked or a renewal is refused.
This guide sets out each step in order, identifies who is responsible for each submission, and lists the points at which fire alarm projects most often lose time. It is written for property developers, building owners, contractors and facility managers, not for individual homeowners.
TL;DR
- Plan approval comes first. Under the Fire Safety Act 1993, any installation, addition, alteration, removal or relocation of a fire alarm panel requires SCDF plan approval before physical works start, unless an exemption or Minor Alterations or Additions (MAA) lodgement applies.
- The system must conform to SS 645. The Fire Code requires an electrically supervised fire alarm system complying with SS 645 where the floor-area thresholds for the building’s purpose group are exceeded.
- Occupation requires an FSC or TFP. A Fire Safety Certificate, or a Temporary Fire Permit where only minor items remain, is issued after a Registered Inspector certifies the works.
- Approval does not end at handover. Designated buildings must hold a Fire Certificate, which for validity starting 1 April 2026 or later runs for 36 months.

What “fire alarm approval” covers
The phrase is used loosely in the industry. SCDF does not issue a certificate titled “fire alarm approval”. The approvals that apply to a fire alarm system are the following.
| Stage | Regulatory instrument | When it applies | Who submits |
|---|---|---|---|
| 1. Before works | Plan approval | Any installation, alteration, removal or relocation of fire alarm panels and related systems | Qualified Person (QP) on behalf of the owner |
| 2. After works | Fire Safety Certificate (FSC) or Temporary Fire Permit (TFP) | Completion of fire safety works, before the building or premises is occupied | Owner and QP, with a Registered Inspector’s certification |
| 3. In operation | Fire Certificate (FC) | Designated public, industrial and private residential buildings | Owner or occupier, with a Professional Engineer’s certification of testing |
Each stage has a different responsible party and a different evidentiary standard. The sections below take them in sequence.
Stage 1: Plan approval before any works
The Fire Safety Act 1993 requires any person who intends to carry out fire safety works to obtain SCDF approval of plans first. SCDF’s plan approval page states that plans are submitted by Qualified Persons on behalf of building owners, and it lists fire alarm panels among the fire protection systems whose installation, addition, alteration, removal or relocation counts as fire safety works.
The scope is wider than the alarm equipment itself. The same page lists changes to the design or layout of spaces that affect escape routes, works affecting fire compartments (including the replacement of fire doors), and works involving combustible materials or air-conditioning and ventilation systems. A tenant fit-out that moves partitions can therefore trigger a fire alarm submission even when no detector is purchased, because detector coverage and alarm zoning depend on the layout.
Exemptions and minor works
Plan approval is not required for works covered by the Fire Safety (Exemption) Order, or for works that qualify as Minor Alterations or Additions and are eligible for lodgement instead of full approval. The distinction matters in practice. A frequent compliance failure occurs at the MAA stage: a small reconfiguration that affects escape routes or fire compartmentation still requires a formal submission or lodgement. Owners should not assume that a project is minor because the budget is small.
Who prepares the submission
The plans are submitted by a Qualified Person, which in most projects is the appointed architect or professional engineer, with the fire alarm design prepared by the relevant M&E engineer. For a clearer picture of the roles involved, see our note on who certifies fire safety works in Singapore. For the wider submission process across commercial and industrial premises, see our guide to building plan SCDF submission.
What the design must comply with
The technical basis for the plan is the Fire Code. Under Clause 6.3 of the Fire Code 2023, every building or part of a building, other than residential floors in purpose groups I and II, whose total floor area exceeds the threshold in Table 6.3A for its purpose group must be installed with a fire alarm system. The table specifies whether the system is automatic or manual, and the system must be electrically supervised and comply with SS 645.
Several design points follow from the clause.
- Fire alarm panel. An electrical fire alarm system, automatic or manual, must have a panel that indicates the location of the alarm that has been actuated.
- Dormitories. Single-storey dormitory buildings require a manual system complying with SS 645. Dormitories exceeding one storey require both automatic and manual systems.
- Residential floors. Purpose group I and II residential floors are excluded from the general clause, so a mixed-use development needs the purpose group of each part established at the outset.
SCDF’s circular on the implementation of SS 645:2019 concerns the code of practice for the installation and servicing of electrical fire alarm systems. Designers should confirm the edition and any amendments current at the date of submission rather than rely on earlier project templates. For a wider reading of the code, our guide to the SCDF Fire Code summarizes how the chapters interact.
Addressable systems and the maintenance contract
Most new commercial and industrial installations use addressable fire alarm systems. SCDF’s briefing for Fire Safety Managers on addressable fire alarm systems notes that these are mostly proprietary systems, so maintenance contractors must be authorized and trained to maintain them. This has a design consequence: the choice of panel manufacturer at the plan stage determines which contractors can service the system for the rest of the building’s life. Owners should confirm servicing arrangements before the equipment is specified, not after the FSC is issued.
Stage 2: Installation, inspection and the Fire Safety Certificate
Once plans are approved, works may proceed strictly as approved. Any departure from the approved plan, such as relocating a panel because of a late coordination clash, should be resolved through the QP and, where required, a revised submission before it is built.
When works are complete, the owner and the QP apply for a Fire Safety Certificate. According to SCDF’s page on the Fire Safety Certificate and Temporary Fire Permit, the FSC is the approval for the use and occupation of the building, and a Registered Inspector must be engaged to inspect and certify the fire safety works before the application is made. The role of the Registered Inspector arises from the Fire Safety Act 1993 and the Fire Safety (Registered Inspectors) Regulations 1994: the inspector’s certificate is a prerequisite for a TFP or FSC.
Temporary Fire Permit
Where fire safety works are near completion and only minor items remain outstanding, the owner may apply for a Temporary Fire Permit, which allows limited occupation. It is not a substitute for the FSC. Occupying premises without either document is an offense under the Fire Safety Act 1993 and can lead to court action, and a TFP carries an obligation to close the outstanding items promptly.
Acceptance testing readiness
Before the Registered Inspector attends, the project team should hold the following in a single file:
- The SCDF-approved plans and any approved amendments.
- Equipment documentation for the panel, detectors, manual call points and sounders.
- Installation and commissioning records signed by the contractor.
- Evidence that cause-and-effect interfaces (fire doors, smoke control, lift recall, pressurization fans) respond as designed.
- Records of the servicing arrangement for the installed system.
A missing item at this stage is the most common reason an inspection is repeated. Our guide to obtaining a Fire Safety Certificate walks through the application sequence, and the note on FSC requirements for building owners covers owner obligations in more detail.
Stage 3: The Fire Certificate in operation
A building with an FSC is not necessarily within the Fire Certificate scheme, but many are. Under Section 35 of the Fire Safety Act 1993, the owner or occupier of designated public buildings, such as offices, hospitals, shopping complexes, industrial buildings and certain private residential buildings, must hold a Fire Certificate.
SCDF states the following parameters, which should be confirmed against the page at the time of application because they can change:
| Item | Position published by SCDF |
|---|---|
| Validity (start date from 1 April 2026) | 36 months, replacing the previous 12-month cycle |
| Fee, non-residential premises | $33 per storey |
| Fee, residential premises | $11 per storey |
| Typical processing time | About 21 business days |
The longer validity period does not reduce the underlying duty. The scheme is an assurance that fire safety installations, including the fire alarm system, are maintained and tested in accordance with the relevant codes of practice, and SCDF conducts selective audits. Responsibility remains with the owner or occupier, who must engage a Professional Engineer to certify the testing. Our overview of Fire Certificate compliance covers the renewal documents in detail.
Designated buildings meeting the stated conditions, for instance public buildings of nine storeys or more, must also appoint a Fire Safety Manager, as set out in the SCDF Fire Certificate application form. The Fire Safety Manager is the person who monitors system reports and maintenance performance day to day.
Where fire alarm approvals lose time
The delays below recur across commercial, industrial and mixed-use projects. Each is avoidable with earlier coordination.
- Works begin before approval. Because plan approval is a precondition under the Fire Safety Act 1993, work installed ahead of approval carries the risk of being removed or modified. Procurement can proceed in parallel, but installation should not.
- Layout changes treated as architectural only. Relocating partitions or fire doors changes detector coverage, alarm zones and escape routes. The fire alarm drawings should be revised with the layout, not after it.
- Minor works assumed exempt. Lodgement under the MAA route still requires a formal submission where escape routes or compartmentation are affected.
- Equipment selected without a servicing plan. Proprietary addressable systems require authorized contractors. SCDF’s Fire Code guidance expects owners to hold formal agreements with competent contractors or manufacturers’ representatives so that a competent person is available when a fault develops.
- Maintenance procured on price alone. SCDF’s briefing for Fire Safety Managers observes that addressable systems are often underused when low-cost contracts are preferred, and that technically competent servicing is needed to manage signal data and reduce false alarms.
- Incomplete close-out files. The Registered Inspector certifies against the approved plans. Records that cannot be traced to the approval cause repeat inspections.
Our perspective
We handle fire alarm approvals as part of a wider statutory sequence, because the alarm system rarely fails on its own. It fails at the interfaces: between the architectural layout and the detector design, between the M&E contractor’s as-built condition and the approved plan, and between the handover file and the Registered Inspector’s checklist.
Our practice is to establish the purpose group and the applicable Fire Code threshold first, confirm whether the works require full plan approval, an MAA lodgement or an exemption, and only then issue the design. We recommend that owners decide the servicing arrangement for the panel at the same time as the equipment is specified, since the choice binds them for the life of the installation. We also advise treating the Fire Certificate cycle as a maintenance calendar from the day the FSC is issued, so that the Professional Engineer’s testing and the Fire Safety Manager’s records are ready well before the renewal date.
Our multidisciplinary Professional Engineer team and single-point statutory coordination are intended to keep these interfaces under one responsibility, which is the principal reason projects clear authorities without repeated resubmission.

Support from Aman Engineering Consultancy
For owners and developers who need the submissions coordinated, we provide authority approvals, including Fire Safety Certificate applications, together with PE endorsements and the related inspection services. Where a fire alarm project forms part of a larger renovation, mezzanine or addition and alteration scheme, the same team can manage the multi-agency sequence, as described in our guide to authority approvals for renovation. To discuss a specific project, contact us through the Aman Engineering Consultancy website.
A practical sequence for owners and developers
For a new installation or a replacement of the alarm panel, the following order keeps the approval path clear.
- Confirm the purpose group and the Fire Code 2023 Clause 6.3 requirement for each part of the building.
- Appoint the Qualified Person and, where relevant, the M&E engineer for the fire alarm design.
- Decide whether the works need plan approval, qualify for MAA lodgement or fall under the exemption order.
- Specify equipment together with a servicing plan that names authorized contractors.
- Obtain approval and build strictly to the approved plans.
- Engage the Registered Inspector early, and prepare the close-out file before the inspection date.
- Apply for the FSC, or a TFP if only minor items remain.
- Enter the Fire Certificate cycle, with testing certified by a Professional Engineer and records kept by the Fire Safety Manager.
Fire insurance requirements can also depend on holding a valid FSC, which is discussed in our note on FSC and fire insurance.
FAQ
What are the requirements for fire alarm systems under SCDF rules?
Buildings above the floor-area thresholds in Table 6.3A of the Fire Code 2023 must have an electrically supervised fire alarm system that complies with SS 645, automatic or manual according to purpose group. Residential floors of purpose groups I and II are excluded from that clause. The design must be submitted for plan approval by a Qualified Person before installation.
How do I get a fire alarm certificate?
There is no single certificate by that name. After the approved works are complete, a Registered Inspector certifies them and the owner and QP apply for a Fire Safety Certificate, or a Temporary Fire Permit if minor items remain. Buildings in the designated categories must additionally hold a Fire Certificate.
How many years is a fire alarm certificate valid?
For a Fire Certificate with a validity start date from 1 April 2026, SCDF states a validity of 36 months, replacing the earlier 12-month cycle. The Fire Safety Certificate is a different document, issued on completion of works. Confirm current terms on the SCDF page before applying.
Is approval required to replace an existing fire alarm panel?
Yes, in most cases. SCDF lists the installation, addition, alteration, removal or relocation of fire alarm panels as fire safety works requiring plan approval. Only works covered by the Fire Safety (Exemption) Order, or eligible for MAA lodgement, follow a different route.
