Introduction To FGS
FGSs shall detect at an appropriately early stage
The presence of flammable and toxic gases, the presence of a fire, the presence of smoke from
smoldering or incipient fires.
What is FDS
-
A monitoring device designed to automatically inform the central station monitoring services of any fire hazards at the designated area before it had a chance to get out of control and bring harm / fatality to the person and facilities around.
Fire Detection System and its related detection system shall comply with the requirements of instrument protective function.
The interface between the sensor and the FGS IPS shall be either a 4 - 20ma signal or a potential free contact.
If the initiator are of the normally open (quiescent current) design, continues line monitoring facilities capable to detect open loop and short circuit shall be applied and an alarm raise when fault is detected.
Fire Detection
System shall detect at an appropriately early stage: The presence of a
fire. The presence of smoke from smoldering or incipient fires.
Fire Detection System and their associated equipment shall be determine during detailed engineering as such detectors and their location shall be indicated on the master plan of fire safety system.
Fire and Gas Detection Mapping software has been developed to enable an engineer to:
1. Determine the correct location to place fire and gas detectors.
2. Optimizing the effectiveness of the FGS.
3. Considering different detector locations.
4. Evaluate different voting strategies.
