Smoke Detection

Fire-Detection systems can be signal-only, therefore with ‘human’ intervention, or automatic / manual. In the first case, with the exception of the possible deactivation of the user, the plant monitors the activities of sensors operating on various atmospheric agents (gas, smoke, carbon monoxide, etc.) 24 hours a day. When an alarm occurs there is an acoustic warning alerting the supervisors; in the case of automatic/manual system the plant is managed automatically, the system give the acoustic alarm, signal the fire and operate for a gas shut off to extinguish the outbreak in progress.

THE CONVENTIONAL SYSTEM

A conventional system is composed of a control unit to which field devices are connected, smoke detectors, alarm buttons, sirens and optical tellers.
These devices are subdivided into different zones, depending on the size of the area where they are installed. In the event that one of these devices goes into alarm, the control unit will signal as alarm all the zone to which the affected device is connected. This type of system is suitable for small installations and when it is not necessary to individually identify the device in alarm.

SIEMENS FC10

The FC10 fire detection plants process the signals from automatic and non-automatic detectors belonging to the following technology. Collective detectors belonging to the DS 1100 range.

ANALOGUE SYSTEM

An analog system composed by a control unit and field devices, the main difference being that the devices are encoded one by one, so the control unit can locate them individually, based on assigned number. Also in an analogue system, smoke and heat detectors report not only the alarm condition, but they are able to determine, for example, how much smoke there is in the room, ensuring absolute accuracy in signaling the alarm condition.

SIEMENS CS1115 / FC330A (OUT OF PRODUCTION)

The FC330A has all the requirements for intelligent systems. Addressing is automatic and address allocation takes only seconds. To improve security and increase speed, distributed intelligence enables detectors to verify danger signals independently.

512 addressable and 384 conventional fire detectors, regardless of type, may be connected to the FC330A fire control panel.
Commissioning, which comprises auto-addressing of all connected elements, is executed by the intelligent SynoLOOP transmission protocol. Time-consuming preparatory work such as setting dip switches, etc., is no longer necessary, providing reliable ontime commissioning.

Siemens equips all auto-addressable elements with isolators. No separate isolator has to be planned nor installed. If a short circuit occurs, the panel localizes and isolates the defective cable section. The loop system permits data flow in both directions up to the error source with optimum safety, until short-circuit is fixed. This kind of automatic isolation facilitates fire section planning, as well as adaptation to changing needs.

Expansion with various additional cards permits almost unlimited customized solutions.

AUTOMATIC EXTINCTION SYSTEM

The purpose of an effective AUTOMATIC EXTINCTION is simple: turn off the fire at birth, before any damage caused by the destruction of the protected value. It is therefore crucial to choose the extinguishing agent suitable for the specific application and risk situation. There is no universal extinguisher for any type of fire but there is a wide range of products that are ideal for the specific application.

Fire extinguishers clean, electrically non-conductive, can be used on electrical appliances as they don’t degrade electronic material. It has a high power off. The discharge takes place in 10s only and the extinction can take place in a few seconds. Thanks to the high pressure technology (10 bar at the nozzle and 42 bar in the cylinders), the switch-off capacity is much faster than conventional low pressure systems. In fact, this technology guarantees:

  • The rapid diffusion of the extinguishing agent into the protected volume;
  • The total evaporation of gas during discharge is due to the small size of the drops produced at the nozzle and to their rapid evaporation due to a high heat exchange;
  • The perfect homogenization of the extinguishing agent in the protected environment even before the complete saturation of the environment itself.
