Fire Detection Systems
Fires have become a major problem in South Africa and can easily be started by overheating machinery and power surges. It is now a legal requirement in South Africa (SANS 10400) for all buildings that exceed 30m in height (approx 10 floors) or contain any floor exceeding 5,000m2, to be equipped with a fire detection system. The system also must be designed, installed and maintained by competent persons (SANS 10139). By investing in a integrated fire detection system you not only abide by the law, but you can also save your company and employees from becoming another statistic.
Conventional and Addressable Fire Detection
Smoke detectors are very effective tool at alerting people in the immediate vicinity of where the smoke is detected. However if you want save your business from serious damage you need an integrated fire detection system. The system not only alerts people throughout your building by triggering the fire alarm but it can also summon emergency services. There are two types of systems available – addressable and conventional.
Addressable systems monitor the specific location of each device (eg smoke detector, call point or sounder). It means in the event of a fire or other emergency you know exactly where the problem is. This saves precious time and helps the emergency services prevent the loss of life and serious damage. With a conventional system you can only determine the problem is in a general area, so they are only suited for small sites.
Fire Detection System Options Available
We can design and install a fire detection system that will address the specific challenges of your business using the following items:
- Smoke alarm and smoke detectors – Can operate independently or part of an integrated fire detection system. We offer a wide variety which include ionization, dual optical and optical (also called photoelectric) smoke detectors. We do not recommend battery operated, wireless smoke detectors are they are not compliant with SAQCC regulations
- Heat detectors – a very efficient device at detecting temperature increases caused by fires. Highly recommended for places with a lot of non-smoke gases eg car exhaust fumes and chemical fumes. Advanced detectors like the Avenar range from Bosch can detect both smoke and temperature increases.
- Call Points / Fire Boxes – Manually operated buttons (see image above left). Used to trigger the fire alarm
- Fire alarm / fire sounders / bells / sirens – Provides an immediate audio alert to any fire out breaks.
- Fire strobe light – Provide an instant visual alert to an fire out break
- Gas Suppression systems – Quickly extinguishes all types of fire. Used in areas where water and chemicals would likely cause damage. Recommended for offices, server rooms and art installations.
- Optical beam detection/ Smoke detection beams (pictured below right) – Can detect smoke in large areas. It can differentiate smoke from exhaust fumes and other chemicals. Recommended for underground car parks, garages and chemical and petrochemical facilities
- Carbon Monoxide (CO) detectors – CO is a poisonous gas that is completely colourless, tasteless and odourless. Our detectors can save the life of your employees and customers
- Automatic fire curtains – Seals off an area to contain the fire and prevent it from spreading into other areas.
- Voice Evacuation System – broadcasts prerecorded messages over the buildings PA system. Informs personnel what event has happened and directs them to safety.
Fire Detection System Servicing
Please be aware that in accordance with South African regulations SANS 10139:2012 your fire detection system must be serviced every 6 months. This is a legal requirement and it must be recorded in a log book and signed off by a certified fire technician. Failure to comply can result in your insurance company refusing to settle a claim after a fire incident.
At IntelliSEC we also only use safety and emergency equipment from leading manufacturers like Technoswitch, Ziton, Bosch and Fire Beam. These systems conform to the SANS 10139 standard and have proven to be stable and reliable in the most demanding of environments. All our fire detection technicians are registered and fully certified by both the PSIRA and the SAQCC Fire. These associations have recognised us as an authorised designer, installer and servicer of fire detection systems. This allows us to fully certify the systems, enabling our clients to obtain discounted business insurance premiums.
We have experience in installing fire detection systems in a wide variety of industries and can provide you with a customised solution. For example the systems we install at hospitals also conform to SANS 322. We can also support you anywhere in South Africa. We have branches in Cape Town, Durban, Johannesburg, Richards Bay and Port Elizabeth.
