FIRE PROTECTION SYSTEM

PURPOSE:

An automatic fire alarm system is designed to detect the unwanted presence offire by

monitoring environmental changes associated with combustion. In general, a fire alarm system is

classified as either automatically actuated, manually actuated, or both. Automatic fire alarm

systems are intended to notify the building occupants to evacuate in the event of a fire or other

emergency, report the event to an off-premises location in order to summon emergency services,

and to prepare the structure and associated systems to control the spread of fire and smoke.

DESTGN:

After the fire protection goals are established - usually by referencing the minimum levels of

protection mandated by the appropriate model building code, insurance agencies, and other

authorities - the fire alarm designer undertakes to detail specific components, arrangements, and

interfaces necessary to accomplish these goals. Equipment specifically manufactured for tl~ese

purposes are selected and standardized installation methods are anticipated during the design

Fundamental Configuration

a) Initiating Devices

Manually actuated devices; Break glass stations, Buttons and manual fire alarm

activation are constructed to be readily located (near the exits), identified, and operated.

Automatically actuated devices can take many forms intended to respond to any number

of detectable physical changes associated with fire: convicted thermal energy; heat

detector, products of combustion; smoke detector, radiant energy; flame detector,

combustion gasses; carbon monoxide detector and release of extinguishing agents; water-

flow detector. The newest innovations can use cameras and computer algorithms to

analyze the visible effects of fire and movement in applications inappropriate for or

hostile to other detection methods.

b) Notification Appliances

Audible, visible, tactile, textual or even olfactory stimuli (odorizer) to alert the occupants

Evacuation signals may consist of audible or visible appliances with a distinct audible

tone or speakers to deliver live or pre-recorded instructions to the occupants.

FIRE PROTECTION SYSTEM FOR 9 MWp GRID INTERACTIVE SOLAR PV PLANT

a) In each of the nine PCU rooms there is one number of optical smoke detector to detect the presence of any fire condition and flasher are installed outside the PCU room which will indicates the fire condition in their respective PCU rooms. As PLC's are located in each of the PCU room so a smoke detector acts as digital input to that PLC and flasher outside the PCU room acts as a digital output to that PLC. In case of any fire condition i.e. smoke a digital input is received by plc which switches on the flasher outside the PCU room to indicate the emergency condition. Plc is mounted with acknowledgement button to acknowledge the fire condition.

b) Any fire condition inside the main control room is communicated through main PLC panel located in PCU room number five through seven detectors placed inside the Main Control Room.

c) Manual call points are installed outside each PCU room, three numbers in main control room at the exit and entrance, and one number inside the guard room to activate the alarm condition in case required.

d) Guard room is equipped with one PLC looped with main plc through a fiber optic cable and connected to an alarm annunciator panel inside the guard room to visualize the alarm condition in any of the PCU rooms and main control room.

e) Hooters are installed inside the guard room and are activated in case of any fire condition in any of the rooms.

f ) Any of the fire condition in the plant installed with detectors will be indicated in the SCADA.

g) The PLC's used for Fire Protection System and SCADA are same.

NOTE: Please refer to the system architecture of Fire Protection System.
