Comprehensive fire detection system layout for a five-level building (basement, ground floor, 1st floor, 2nd floor, and roof level) totaling approximately 2,537 m². The design implements a dual-loop addressable fire alarm system with detailed device placement and wiring routes.
System Components:
– 8-circuit addressable fire alarm control panel with 960 address capacity
– Addressable optical smoke detectors with short circuit isolators
– Addressable combined optical smoke and heat detectors
– Addressable gas detectors (including CO detection)
– Addressable manual call points with short circuit isolators
– Addressable relay and monitoring modules
– Addressable flasher/sounder units (wall and ceiling mounted)
Wiring Specifications:
– Loop circuits: 2x2x0.8+0.8mm² JH(st)H FE180 fire-resistant cable
– Sounder/flasher circuits: 2×1.5mm² N2XH FE-180 fire-resistant cable
– Control connections: 2×0.75mm² and 3×0.75mm² LIHCH cable
The layout follows a logical zone-based detection strategy with careful consideration for coverage areas and escape routes. The design includes provisions for interfacing with other building systems through monitoring and control modules.
