We design, install and maintain fire-detection systems that identify a fire early and drive the right response. The work spans detector selection for the environment, addressable zoning, cause-and-effect programming, and integration with alarms, suppression and building systems — engineered and documented to SANS 10139.
The problem
Detection that triggers too late gives occupants no margin and lets a fire take hold. Detection that triggers too often trains people to ignore it and prompts staff to disable devices. Both come down to the same root cause: detectors and zoning that were not matched to the actual environment. Reliable early warning depends on selecting the right detection technology for each space and proving the system end to end.
Our approach
Individually addressed devices for precise fault and event location, maintainable layouts and clear zone reporting, designed to SANS 10139.
Aspirating smoke detection, flame and linear heat detection for high-airflow, high-ceiling or harsh environments where point detectors are unreliable.
Detector type chosen for each space — including electronic-equipment areas (SANS 246) and hospital environments (SANS 322) — to give early warning without nuisance alarms.
Programmed response logic that maps each detection event to defined actions: alarms, suppression release, HVAC shutdown and interlocks, documented as a cause-and-effect matrix.
Centralised control with event logging, fault diagnostics and remote monitoring so faults are seen and acted on, not discovered at the next inspection.
Scheduled servicing, testing and a documented maintenance record that keeps the system compliant and defensible for insurers and authorities.
Every detection input maps to specific outputs. This matrix defines which actions are triggered by which events - the core of fire-system response logic.
When false alarms persist, each branch of this decision tree isolates a root cause - from environmental interference to wiring faults - and directs a corrective action.
Service Evidence
A compliant service visit generates documented evidence at every step - not just a pass/fail sticker, but traceable records that responsible persons can rely on.
Download and review all events since last service - faults, alarms, isolations and operator actions recorded on the panel.
Measure standby battery voltage under load and compare against minimum threshold for compliance and evacuation duration.
Each detection head tested to manufacturer sensitivity specification - optical, thermal or multi-sensor as applicable.
Trigger each input in turn and confirm the correct output actions fire as programmed - sounders, visuals, plant shutdowns.
Confirm all zones correctly labelled, devices mapped, and zone plans match the physical layout across the protected site.
Written findings, outstanding actions, risk observations and next-service scheduling delivered as an evidence record.
Zone Planning
Zone boundaries are drawn around building geometry, occupancy risk and evacuation logic - not convenience. These principles guide compliant zone planning.
Split zones at the angle change. Each wing operates as a separate detection zone with independent alarm routing and evacuation direction.
One zone per floor per fire compartment. Stairwell zones treated separately for phased evacuation sequencing and floor-by-floor fault isolation.
Maximum 2000m² per zone. Detector spacing and type selected for ceiling height, airflow conditions and occupancy profile.
Dedicated zone with enhanced detection density, faster response threshold and direct suppression interface - server rooms, switchgear, process plant.
Case study
Data Centres
An ageing CO₂ system protected a live colocation hall, creating a personnel-safety risk and falling short of a tenant compliance review.
Representative scenario — not a named client or measured project result. Replace with approved project evidence before using as a real case study.
FAQ
A conventional system reports an alarm by zone, so you know roughly where but not which device. An addressable system identifies the exact device, giving faster location of both alarms and faults. For anything beyond a small, simple site we design addressable systems for this reason.
Most false alarms come from the wrong detector in the wrong place. We match detection technology to each environment — for example aspirating detection in high-airflow areas — and use cause-and-effect logic and verification so a single transient event does not trigger a full response.
Yes. We program a cause-and-effect matrix so a confirmed event can release suppression, shut down HVAC and trigger interlocks in the correct sequence. This is documented and tested at commissioning.
