Sample questions
01What type of cable is typically used for central battery emergency lighting systems?
- AFire-resistant cable
- BAluminium cable
- CStandard PVC cable
- DCoaxial cable
Why: Fire-resistant cables are used to ensure circuit integrity during fire conditions.
02What is the minimum fire resistance period required for emergency lighting cables?
- A90 minutes
- B60 minutes
- C30 minutes
- D15 minutes
Why: BS 5266-1 accepts cables classified to the PH30 rating of BS EN 50200 (30 minutes circuit integrity) as the minimum for emergency lighting; longer-duration or sleeping-risk systems may specify PH60 or PH120.
03Why is circuit segregation important in emergency lighting systems?
- ATo prevent a single fault from disabling all emergency lighting
- BIt removes the need for fire-resistant cable
- CIt allows a smaller battery to be specified
- DIt reduces the total length of cable required
Why: Segregation ensures faults do not affect the entire emergency lighting system.
