Study Notes
Fire Protection System
-
Objectives: Maintain conditions conducive to life safety, property protection, and minimized business interruption.
-
Elements of Fire Protection: Early Detection & Alarm System, Means of Egress, Compartmentation, Smoke Control, Emergency Power, Fire Suppression System.
-
Types of Fire Protection Systems: Detection systems, Fireproofing for buildings, fire walls, fire barriers, fire doors, Smoke control systems, Sprinkler systems, Standpipe system, Special extinguishing systems (chemicals, foam, clean agents).
Standpipes & Fire Hoses
-
Automatic Wet System: Water supply within the piping, ready on demand; considered most effective and reliable.
-
Manual Wet System: No inherent water supply; water must be pumped into the pipes by the fire department.
-
Automatic Dry System: Normally filled with pressurized air, used where the risk of freezing is a concern; hose valve required for water.
-
Manual Dry System: No internal water supply, the water has to be pumped into the pipes by the fire department; commonly used in parking garages.
-
Semi-automatic Dry System: Similar to an automatic dry system but has a remote control to activate the valve to admit water.
-
Allowable Sprinkler Pipework: Domestic (solvent cement bonded, CPVC), Industrial and commercial (threaded galvanized mild steel).
Wet-Pipe System
- Components: Distribution pipe, range pipes, riser to higher floors, hydraulic alarm gong, filter, supply to hose reels, sprinkler heads, fire brigade inlet, stop valve, drain pipe, and non return valve.
Dry-Pipe System
- Components similar to wet pipe system; a dry pipe system will not have water flowing in the pipes, water has to be pumped in from a fire station.
Two-End Side with Centre Feed Pipe
- Components: Distribution pipe, range pipes, sprinkler heads.
Two-End Centre with Central Feed Pipe
- Components: Distribution pipe, range pipes, sprinkler heads, and riser.
SPRINKLER SYSTEM
-
Range Pipe: Sizes and maximum allowable sprinklers for different sizes of pipe.
-
Sprinkler Head: Sizes and maximum allowable sprinklers allowed for different distribution pipe sizes.
Fire Protection System: Sprinkler Head Spacing
-
Area covered by one head (maximum): 12.00 m².
-
Distance between heads: 4.00 m (maximum).
-
Distance from wall to ceiling with mounted head: 2.00 m (maximum).
-
Distance between heads in the same room: 2.00 m (minimum).
Fire Protection System: Quartzoid Bulb
- Types: Orange (57°C), Red (68°C), Yellow (79°C), Green (93°C), Blue (141°C), Mauve (182°C), and Black (204 or 260°C).
Signal System
-
Types: Fire Alarms, Telephone Systems, Security Systems, Central Monitoring & Control Systems
-
Components: Signal source, means of conveying the signal, indicating equipment at the destination.
-
Symbols: Different symbols for indicating various signal sources.
Signal System Initiating Device
- Alarm Initiating Device: Fire and Smoke Detectors, Manual Detection with Pull and Station, Audio Indicators (Bell Horns).
Local Area Network (LAN) Systems
- Components: Horizontal Telecom Closet, Backbone, Main Cross-Connect, Intermediate Cross-Connect
Wireless Area Network (WAN) Systems
- Components: Internet connection, DSL Modem, Wireless PCs, LAN type.
Security Systems
-
Purpose: extend surveillance activities, reduce crime incidence.
-
Devices: CCTV, Motion Detectors, Intrusion Detectors, Scream Alarms.
Central Monitoring & Control Systems
- Purpose: controls and operates service systems (HVAC, Lighting, Shading Devices, Electrical Loadings) in a building.
