The design of a smoke detection complies with the UNI 9795 Standard “Fixed automatic fire detection and alarm signals” (2013), the “Installation and construction Standards for automatic fire detection systems”, the UNI EN 54 and the EN 60849 (CEI 100-55) Standard – Electroacoustic systems applied to emergency services.
Depending on the application field, also the following regulations applying to specific sectors must be observed:
Fixed, automatic fire detection systems rapidly detect and signal fires. Fixed, manual signaling systems emit a signal only after a fire has been detected by somebody. In both cases the fire signal is transmitted and visualized at a central/signaling control unit and possibly re-transmitted to a video surveillance central unit. Quick fire detection may save the life of many people and therefore correct design of fire systems is crucial.
The purposes of a fire detection system can be summarized as follows:
The detection system must lead to the automatic activation of the following functions:
In all cases of crowded or high-risk places, emergency vocal alert systems compliant with the UNI ISO7240 and the CEI EN 60849 Standard are provided; the people present are warned about the presence of hazards requiring safe and controlled evacuation.
In view of the above, the smoke detection central unit is provided with an interface with the acoustic (loud speakers) evacuation system through a dedicated output. The sound diffusion system for emergency voice alert has a very important function: managing the evacuation of the whole building or part of it in the case of hazards and/or alarms in compliance with a plan established in agreement with the Head of Prevention and Protection of the organization.
The sound diffusion system for emergency voice alert consists of the following:
A fire extinguisher system is installed inside technical rooms or particularly critical areas. The system is managed, controlled and interfaced with the fire alarm by independent interlocking in each individual room. The system consists of the following:
Depending on the specifications, on the rooms to be protected and on their content, we offer the following systems:
