How Are Area’s Calculated Close

Dedicated Heads:
  • Small Area 50x Dedicated Heads
  • Medium Area 250x Dedicated Heads
  • Large Area 500x Dedicated Heads
  • ½ Dedicated Heads are pinspot open area style luminaires, range optical distribution @ 3m = 10x10
  • 3/8 Dedicated Heads are IP65 bulkheads with optical distribution @3m = 10x 10
  • Remaining 1/8th are exit signs
  • 7/8th of products are 10x10m
  • Small 50x7/8 = 44
  • Medium 250x7/8 = 219
  • Large 500x7/8 = 348
  • 10x10m distribution = 100m2 Coverage
  • Small Area 44x100m2 = 4400m2
  • Medium Area 219x100m2 = 21,900m2
  • Large Area = 348x 100m2 34,800m2
  • Typical utilisation of the area’s is difficult to quantify but BS5266-1 requires many “points of emphasis” and two luminaires “per compartment” which dramatically reduces the maximum area a luminaire can serve. A 40% reduction has been applied for typical area and then rounded to the nearest 500m2 to give the typical area’s found in “area selection”
Mains Conversions:
  • Small/Medium and Large Area’s calculated from dedicated heads (left text box)
  • Small Area 44x100m2 = 4400m2
  • Medium Area 219x100m2 = 21,900m2
  • Large Area = 348x 100m2 34,800m2
  • For 50/50 Splits the mains only needs to cover half of this area.
  • For 100% Mains the mains emergencies needs to cover the whole area.
  • A mains luminaire will cover 32.5m2 to 0.5lux and 1:40 uniformity.
  • The remaining area is divided by 32.5m2 to give the amount of mains luminaires.
  • Area utilisation as per the left text box.

Assumptions Close

  • Cost of installing an emergency luminaire £12.50
  • Labour Rate £25 per hour
  • Out of hours rate £37.50
  • Twin & Earth per m (installed) £6.92
  • FP per m (installed) £7.20
  • Data Pair per m (installed) £1.78
  • T&E Per luminaire (SC) 2m
  • FP per luminaire (3m Dualguard, mixed functionality on final circuit), (6m CPS No test, split circuits required)
  • Data Pair per luminaire (5m)
  • Battery install for CPS included
  • All commissioning costs included
  • No lamp replacement/failures taken into account
  • Manual functional/duration check of lamps 5 minutes per luminaire, per month
  • Batch/bulk battery change at 4years SC and 10years CPS
  • Battery change 30mins per luminaire out of hours
  • Battery change for CPS based on size of system but typically 1-3days
