FIRE DETECTION

A fire detection system consists of electronic equipment that can detect and promptly report the presence of a fire inside a building, the aim being to protect and safeguard the physical integrity of people and property. Surveye installs fire-fighting systems and fire-prevention solutions that are able to reduce the frequency of occurrence and ensure protection, so as to limit the extent of the damage caused.

The main fire protection measures are:

  • automatic fire detection systems
  • automatic water extinguishing systems (sprinklers)
  • manual extinguishing means and fixed extinguishing means (fire extinguishers, hydrant network)
  • smoke and heat exhaust systems.

TYPES OF FIRE DETECTION SYSTEMS

Surveye designs and installs various types of automatic fire detection systems with a different configuration and connection, depending on the requirements of the setting to be protected: it is possible to opt for a system with selected surveillance or total surveillance. The former system has a conventional detection function and comes with a control unit able to identify whether the fire has developed in a certain area – where a group of detectors has been installed – but not to identify precisely which detector triggered the fire alarm.

Conventional fire detection systems are suitable for use in small settings and rooms, where the absence of identification by the detectors is not particularly important. A total surveillance fire detection system – also known as digital addressable fire detection system - exceeds the limits of a conventional system: its detectors – each with their own ID identifier – transmit to the control unit a specific coded signal that allows the identification not only of the generic zone from where the alarm has triggered but also the precise point of the setting in which the detector that sent the alarm signal is installed.

A FIRE DETECTION SYSTEM CONSISTS OF:

CONTROL UNIT

The control unit consists of a plastic self-extinguishing case that is resistant to impact and suitable for wall installation. It receives signals from connected sensors, determines the type of alarm and it can also record events. The optical and acoustic devices activate to signal any anomalies, such as short circuits, power supply interruptions or failures. More specifically, the control unit activates the various rescue devices connected to it for the temporary extinction of the fire.

SENSORS

The sensors detect any fire-associated physical or chemical phenomenon and send a signal to the control unit. The optical sensors visually detect the presence of smoke and flame, while thermal sensors identify any changes in temperature.

ALARMS

Acoustic and illuminated alarms warn of the dangerous situation and favour the evacuation from the premises.

RESCUE DEVICES

The control unit can be connected to various rescue and temporary fire-extinguishing devices, as well as other systems existing in the building and functional to a rapid evacuation. Surveye can also provide for the installation of rain-type sprinklers, smoke and heat extractors and elevators, the implementation of emergency lighting systems and the shutdown of technical systems, but also the installation of fire dampers or electromagnetic door stops.

FIRE PROTECTION IS MUCH MORE EFFECTIVE AS IT IS QUICKER

The quicker a fire ignition is identified by fire detection systems, either digital addressable or conventional, the lesser the consequences for the property or people due to the spread of fire.

Only a careful customised design and installation of a professional fire-prevention system guarantee, in case of danger, a reliable and timely detection of fire, either digital addressable or conventional, giving rescuers the time required to evacuate the building and arrange first-aid interventions. For a fire-detection system to be efficient, it must be adequately sized to the volumes, the characteristics and the intended use of the building.

The best price-to-security ratio can be achieved through a careful assessment of these parameters. For this reason, in assessing a system for complex buildings, it is advisable to contact experts in the industry. Surveye offers an all-round qualified service for the design and installation of digital addressable or conventional fire detection systems to meet all possible needs and guarantee the maximum safety at all times.
