Conception of
Design
In this design
the concept of sensing fire is incorporated with Smoke
Detectors (Optical and Ionization in cross zone configuration)
and Heat detectors as per the suitability at the site to
initiate Alarm at a centrally located panel. Hooters located
at strategic points will get activated to draw the attention
of the inmates or the passerby in that area to identify the
seat of life.
On hearing the
Alarm from the hooters located at strategic points one can
rush to Extinguish the fire with suitable Portable
Extinguishers or through the yard hydrants depending on the
nature of fire.
Description of the System / Selection of Detectors
This system
shall consist of suitable detectors, Manual Call Points
Hooters of High Intensity, Central Control Panel and Batteries
for Standby Power. The Detectors suitably selected shall be
located at Strategic Positions in the places of Fire Risk
anticipated by virtue of a thorough study of the area, and
shall be connected to the Main Control Panel through cables.
The Manual Call
Points shall be located at places accessible for the
inmates/passerby in that area, as they run out for help in the
event of an emergency, located at convenient height such that
any one can reach the Manual Call Point in the event of an
Emergency.
The Main Control
Panel shall be located at a place where the Man Power is
available all the time or at least, they can reach the Main
Control Panel as the Hooters go into action, so as to reach
the seat of Fire in the event of an emergency.
The Hooters
shall be located at strategic positions such that they go into
action as the Fire is sensed by the Detectors, to draw the
attention of the inmates/passerby in that area.
The batteries
shall be located near the Main Control Panel, to form standby
power on the event of "MAINS FAILURE".
