What are the most reliable fire detection systems in South Africa?
We get asked this a lot, and the honest answer is that no single brand is “the most reliable”. A system is only as good as how well it suits the enviroment, and how well it’s designed, installed and looked after. In South Africa that means working to SANS 10139, with SAQCC Fire registered technicians and FDIA registered companies doing the work.
We’ve been designing, installing and maintaining fire detection systems for 33 years, from our offices in Pretoria, Stellenbosch and Mbombela. On every site we work on, protecting lives comes first. Most of our work is also on sites where downtime is expensive: data centres, warehouses, cold rooms, mines, agricultural facilities and large commercial buildings. Our systems are built to protect your people and keep your operation running.
As a general guide, here’s how we match detection to the site:
• Addressable systems for bigger or more complex buildings, so you know exactly which device has gone into alarm.
• High Sensitivity Smoke Detection (HSSD) for data centres, battery and generator rooms, cold rooms and mills, where you need warning before there’s visible smoke.
• Wireless systems for occupied buildings and heritage sites, where running cable would cause too much disruption.
• Fibre optic linear heat detection for conveyors, tunnels and other long runs in harsh conditions.
• Flame detection for high-risk industrial areas where a fire can develop in seconds.
• Integration with your BMS, so fire alarms show up alongside the rest of your building controls.
The brands we’re accredited to install:
Fire detection: AJAX, Aritech, Bosch, Edwards, Honeywell, Hyfire, Kidde (Ziton), Securiton, Technoswitch.
HSSD: Edwards, Protec, Securiton, VESDA and Wagner
Linear heat detection: FibroLaser, Protectowire and SecuriHeat
Flame detection: Autoflame and FlameSpec
BMS fire systems: Alliance, GSNet, GSWin and Maestro
We’re SAQCC Fire, FDIA and CIDB registered. We service systems as per SANS 10139 requirements, which also keeps you on the right side of your insurer, and we run a 24-hour emergency call out line.
If you’re not sure your current system would hold up, or you’re planning a new site, get in touch and we’ll come and take a look.
