A number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present.
The Fire Hydrant system is a major firefighting system by distributing the water through a piping network connected to valve posts at regular interval around the building and inside too. The distribute piping establishes connectivity throughout the building with Hydrants, hoses and nozzles by drawing the water from the designated reservoir with suction piping to the pumps and connecting the delivery lines. The system works on desired pressure levels based on the requirement of the building with pressure switches and gauges by operating through MCC panel on auto mode at any given point of time.
It is water distributed through a piping network from the designated reservoir connecting through the pumps. The piping network is spread across all the covered working areas covering minimum of 1500mm radius for each sprinkler point. The sprinklers are fitted at different level of temperatures to act and spray the water for suppressing the fire when the temperature crosses from the set temperature of the sprinkler head.
Predominantly these systems are installed for data centres, server rooms, UPS rooms and electrical room or any high sensitive equipped areas are not allowed the fire suppression with the water. Most of the cases the gas agent used with FM200, NOVEC1230 or any clean agent for avoiding any impact on environment. These agents are electrically non-conductive and does not leave residue and works for all class of fires. The basic construction of the equipment is again through a seamless pipe network above schedule 40 connecting to the Cylinder with an actuator. There are different methods are used for extinguishing the agent such as fire detection system or aspiration systems to know the accurate fire thresholds to activate the actuator and suppress the fire.
Fire extinguishers are a portable equipment’s for suppressing the small amount of fire incidents. These extinguishers are available in all the classes such as A, B and C and different types with Co2 gas cartridges, water based Co2, Dry chemical powders and clean agents. They are also available for a small modular type automatic extinguishes works again the temperature basis having sprinkler head connected to the extinguishers.
PAVA is basically used an annunciation system in addition to the output devises placed to the fire alarm system such as sounders / flashers. The system contains speakers, amplifiers and consoles with the pre-recorded messages and mikes for annunciations. The system is customized for evacuating the public from the fire occurred areas on sequel methods to protect the life of the public present in the buildings. The system can be installed with multiple zones with select switches for annunciation for individual zones or on all call.
It is general telephone system connecting the control room from all the stair cases. In case of an emergency the system is used for communication to the control room for evacuation process from any of the emergency stair case.
