Comprehensive fire detection system design for a 5-level building (basement, ground floor, 1st floor, 2nd floor, and roof level) with a total area of approximately 1,300 m². The system features an addressable fire alarm panel with single-loop architecture (LOOP-1) connecting all detection devices across floors.
Key Components:
– Addressable optical smoke detectors with short circuit isolators
– Addressable combined optical smoke/heat detectors
– Addressable manual call points (fire alarm buttons)
– Addressable flasher/sounder units for visual and audible alarm notification
– CO gas detection panel and gas detectors
– Relay and monitoring modules for equipment control
Wiring Specifications:
– Main detection loop: 2x2x0.8+0.8mm² JH(st)H FE180 fire-resistant cabling
– Sounder/flasher circuits: 2×1.5mm² N2XH FE-180 fire-resistant cabling
– Auxiliary circuits: 2×0.75mm² and 3×0.75mm² LIHCH cabling
The design includes a vertical riser diagram showing loop connectivity between floors and a comprehensive symbol list detailing all system components. The system complies with applicable fire safety standards, providing complete coverage throughout the building with strategic device placement for optimal early detection.
