This presentation delves into emergency management systems including non-automatic and automatic systems, batteries, diesel generators, and rotary systems. It also covers regulations under BS 7671 and details of emergency lighting systems in various premises, emphasizing categories, types, and luminance levels.

Learning Outcome 4 Understand the types, applications and limitations of wiring systems and associated equipment This presentation looks at emergency management systems
Emergency management systems • Non-automatic • operator required • Automatic • no operator • no break • very short break – within 0.15s • short break – 0.15–05 seconds • lighting break – 0.5–5 seconds • medium break – 5–15 seconds • Batteries – fire alarms, emergency lighting • Diesel generators – essential services (hospitals, etc.) • Rotary systems – provides overlap between them
Emergency management systems Using a current version of BS 7671 look up and write down a summary of the following regulations: • 560.6 • 560.6.10 • 560.7 • 560.7.10
Emergency lighting systems • Emergency escape lighting • enables safe exit on power-fail • Standby lighting • enables normal activity on power-fail • Escape route lighting • allows escape via direction-finding routes • Open area (or anti panic) lighting • direction-finding towards escape routes • High risk task area lighting • allows proper shut down in potentially dangerous areas
Emergency lighting systems • Duration • Category of system • Type of premises, which affects luminance levels • Type of system (self-contained or centrally fed) • Category of operation of luminaire • Mounting height and glare
Emergency lighting systems • Maintained • Non-maintained • Sustained • Self-contained You may see these codes – what do they mean? • M3 • NM2 • S1
Fire alarm systems • Property protection • Type ‘P’ • P1 • P2 • Life protection • Type ‘L’ • M • L1 • L2 • L3 Look these up and write down what they mean. Remember – you may be fitting them so it’s important.
Types of fire detection system • Control panel • Wiring system • Manual call points • Automatic detectors • Sounders and, sometimes, visual indicators
Control panel and wiring system • Control panel • location • supply • Wiring system • wiring system for sounders • wiring system for detection circuits
Automatic detectors • Fixed temperature heat detectors • Rate of rise heat detectors • Optical smoke detectors • Ionised smoke detectors
Typical maintenance checks for fire detection systems • Daily inspection • Weekly test • Quarterly test • Annual test • Every two to three years • Every five years
Intruder alarms • Control panel • Proximity switches • Inertia switches • Passive infrared detectors • Ultrasonic detectors • Audible and visual warning devices • Pressure switches • Magnetic switches
CCTV • Wired or wireless • Infrared lighting • Ensure surrounding lighting has good colour rendering
