Designing and installing fire prevention systems
Fire detection systems must safeguard people, assets and premises within the protected areas, promptly reporting the occurrence of dangerous situations.
Evaluation of the type of fire hazards in the locations that need protection is the starting point for choosing the most suitable system. Zanocco SMI protection systems and solutions are developed by fire protection and anti-explosion experts who have wide experience in this sector and in safety technologies.
Zanocco SMI provides fire protection solutions such as:

Fire extinguishing systems for tunnels
A fire prevention system to be used in two new tunnels has been developed. This system is unique because pointing of the monitors is completely automated. The monitors are nothing more than fire-fighting lances driven by three electric motors controlled by a PLC unit. The fire protection system receives a position signal, which is discretized every 10 meters inside the tunnel and provides an indication of where the monitors are to be pointed. Following this the control software proceeds with the mathematical calculations required for positioning the monitor in order to allow the jet to reach the fire point. Zanocco has developed and built 120 “slave” electrical panels for the management of individual monitors and 2 “master” electrical panels to house all the control systems of the plant. Zanocco SMI has developed all the automatic tracking software of the monitors and is one of the first companies in the world to have devised a pointing system and an automatic fire extinction system for tunnels.
Here follows a video showing the first test carried out on open air extinction.
The hermetically sealed system is composed by a pipe sensor fitted in the area to be monitored and has a hermetic cap on one end. At the other end the pipe sensor is connected to the detector box, more specifically to a fully electronic pressure sensor and to a pneumatic control device. The entire pneumatic system contains normal air. The control mechanism consists of a geared motor and a pump. The pressure sensor continuously measures the absolute pressure inside the tube sensor. The sensor signals are analysed mathematically by the microprocessor and can therefore be used to calculate and to realize the differential behaviour. If the pressure increases at the speed defined by the software (mbar / s), the ADW signals a differential alarm. Disturbances (temperature fluctuations due to weather) are filtered. The absolute maximal behaviour of the ADW is designed so that the pressure corresponding to a maximum temperature triggers the alarm, the slow growth and constant pressure over a long period, which is sufficient to trigger the differential function, is then seen as an alarm limit.
The ADW will be installed in a Safe area, while the sensor tube (galvanically insulated) can be placed in the ATEX21 ZONE. A firefighting main unit will be installed (SFP) for the ADW alarm management and correct reporting of an alarm, malfunction or failure.
The ASD System consists of one or two independent pipes with the related suction holes and one or two high sensitivity smoke detectors. By means of a dedicated device the two air flows are constantly monitored to detect any breakage of the pipes or clogging of the holes. A powerful fan draws air from the room or from the equipment to be monitored and conveys it through the pipe to the terminal processor. Here the smoke sensors constantly analyse the air. The control and signaling processor indicates the concentration of smoke in the air intake and the other messages of alarm, failure and status. An increase in the concentration of smoke is quickly detected.
It is possible to program three pre-signals and a main alarm, transmitted via potential-free relay or directly on the loop line. There are four other free slots to allow additional relay modules, interfaces or memory cards to be installed.
Thanks to its excellent response performance, the ASD system is ideal for monitoring equipment and premises. ONE ASD535 DETECTOR (two SSD535 sensors) MONITORS TWO 1200 SQUARE METERS AREAS AND THEREFORE A TOTAL AREA OF 2400mq !!!
The fire detection system for your safety has a highly developed intelligence and reliability and outshines all the systems known so far. It offers extraordinary innovation: it is totally redundant and is designed to ensure double safety which excludes almost any system failures.
All hardware and software components are available in the redundant version and work in parallel as two separate and independent systems If the active system fails, the secondary system takes over the operational process without interruption. This ensures maximum safety and immediate detection of any event of fire, even if the system is damaged by the interruption of several wires.
Modular, decentered structure allows maximum designing freedom. Up to 16 autonomous main control units can be combined in one integral, homogeneous system without the use of a master computer. To each of these interconnected stations up to 14 loop lines with 128 elements each can be connected such as fire detectors and manual call points. While the main unit is fulfilling its main task, which is immediate recognition of fires, the system communicates outwards on several levels. It is connected via interfaces to transmission and alarm equipment, relay outputs as well as monitored inputs and outputs. The planimetric panels and command panels for the firemen are connected via bus to an external unit while contact with higher-level systems is ensured by serial data interfaces. The innovative system can be designed, programmed and controlled in a simple and intuitive way.
