Most fire alarm systems in South Africa are the wrong category, installed without proper certification, or handed over with no documentation. Altrafire designs, installs and commissions SANS 10139:2021 compliant fire detection systems — and issues every certificate the standard requires.

A smoke detector on the ceiling is not the same as a SANS 10139 compliant fire detection system. Most buildings have one. Almost none have the other.
SANS 10139 defines six system categories. The category must be stated in the specification. Most installed systems have no category designation — which means they were likely under-designed, and your insurer can use that against you.
SANS 10139 requires a Design Certificate, Installation Certificate, Commissioning Certificate and Acceptance Certificate. Without these, your system has no legal standing — and no proof of compliance exists.
The standard mandates handover of as-fitted drawings and a system log book. Without them, no future servicing organisation can maintain your system correctly — every maintenance visit is guesswork.
Cable fire resistance, detector spacing, manual call point placement, standby power capacity — all specified in SANS 10139. Incorrect installation voids your certificate and leaves your system non-compliant from day one.
The category of system is the single most important decision in the design process. Your insurer, the enforcing authority and the fire brigade all need to know it. Without a declared category, your system is non-compliant by definition.
⚠ Important: Systems can combine categories (e.g. L2/P2). Your insurer and local authority may prescribe specific categories. If no category has been declared for your existing system, it is non-compliant. Altrafire's free site assessment determines exactly which category your building requires.
Any electrician can put detectors on a ceiling. A SANS 10139 compliant installation requires design engineering, certified commissioning, and full documentation — most contractors skip all of it.
Property insurers often require a specific SANS 10139 category system and valid certification. An uncertified or wrong-category system gives your insurer grounds to reject your fire claim entirely — even if the system activated correctly.
Local authorities and fire departments require compliance with SANS 10400-T and SANS 10139 before issuing occupancy certificates. A non-compliant system blocks your building from being legally occupied.
If a fire results in injury or death and the system is found to be non-compliant, building owners and directors face personal criminal liability under the OHS Act 85 of 1993.
SANS 10139 Section 9 states that systems producing more than 1 false alarm per 25 detectors per annum are non-compliant. Poor design is the leading cause.
Without as-fitted drawings, zone schedules, and a system log book, no maintenance organisation can service your system properly. The standard requires all three documents at handover.
SANS 10139 Clause 11.4 requires that sufficient representatives of the user be properly trained in system operation at handover. This training is rarely provided.
SANS 10139 requires a single organisation to take responsibility at each stage. Altrafire handles the full chain — design through to handover — so there are no gaps and no responsibility disputes.
We visit your premises and assess building type, occupancy, fire risk zones, escape routes, existing systems, and insurer/authority requirements. We determine the correct SANS 10139 system category — and confirm it with you before any design work begins.
Our engineers design your system to the declared category. Detector selection and siting, manual call point placement, control equipment specification, cable specification, power supply sizing, and false alarm mitigation measures — all per SANS 10139 Section 8.
Our technicians install strictly in accordance with the design — fire-resistant cabling, correct detector mounting heights, cable routes that protect circuit integrity. All wiring inspected and tested before commissioning begins. No shortcuts. No substitutions without designer approval.
Every detector, every call point, every sounder, every ancillary function — tested and confirmed. False alarm potential checked. ARC transmission verified. Standby power tested. System confirmed compliant before any handover.
You receive the complete handover pack: as-fitted drawings, operating and maintenance instructions, all four certificates, and a system log book. Your key staff are trained in system operation. You leave the handover knowing exactly what you have.
SANS 10139 requires inspection and servicing every 6 months by a competent person. We offer ongoing maintenance contracts — six-monthly inspections, annual detector testing, false alarm monitoring, log book maintenance, and servicing certificates after every visit.
SANS 10139 covers every non-domestic building type. The category and coverage requirements differ — but the obligation to have a compliant, certified system does not.
