5 EMERGENCY LIGHTING SPACING TABLES To enable photometric designs to be performed as required by BS 52 pts 1 and 7, the following factors need to be used to ensure that the worst case conditions are designed for. Initial lamp lumens of the lamp must be derated by: Ballast lumen factor (for emergency circuits, these are independently tested and their % value is shown) K Factor for the effect of reduction in supply voltage as the battery discharges, and of cable voltage drop on central systems S Factor to compensate for the ageing of lamps during service life. The effect of dirt on the diffuser must also be allowed for, so an allowance for 20% as recommended by ICEL has been built into these spacing tables. If the design is being produced on a computer, similar allowance should be made. System lumen reduction factors used in the following lumens chart are: SYSTEM TYPE SELF-CONTAINED 2 VOLT SLAVE 50 & 1 VOLT SLAVE 230 VOLT INVERTER SLAVE K Factor S Factor When applied with the appropriate Ballast Lumen Factors % with typical fluorescent lamps, they give the following Emergency Lighting Design Lumens (ELDL) for typical fluorescent lamps which can be used for spacing calculations: TRI-PHOSPHOR LINEAR LAMPS Self Contained Central Battery System WATT LUMEN QX SERIES ADV SERIES 2V SLAVE 50V/1V SLAVE 230V SLAVE Type BLF ELDL TYPE BLF ELDL BLF ELDL BLF ELDL ELDL BQX 0 ADV BQX ADV CQX 225 ADV DQX ADV HALO-PHOSPHATE LINEAR LAMPS BQX 85 ADV BQX ADV CQX 2 ADV DQX 5 2 ADV COMPACT LAMPS 1-2D 50 BQX 13 0 ADV D ADV D ADV TC-S 900 BQX ADV TC-D 900 BQX 1 90 ADV TC-D 1200 BQX 85 ADV TC-L ADV TC-L 2900 BQX 7 15 ADV Notes: 1.

Other lamp type/wattage data on request DESIGN PROCEDURE FOR CONVERTED MAINS LIGHTING LUMINAIRES When normal mains luminaires are converted and utilised for emergency use, the procedure below should be followed: 1. The table of emergency lighting design lumens (above), should be consulted to determine the minimum emergency lamp output for the particular lamp/circuit required, for use with either spacing tables or a computer design program. 2. The appropriate spacing table should then be selected and used, checking the following points: That the shape of the polar curve corresponds with the luminaire to be used That the value of the output is similar (LOR and at the nadir. Variations can be compensated for, by determining a ratio for the lamp output value obtained in 1) 3. The spacing limits for escape routes or open areas can then be read off for specific height and lamp outputs. Note: If different values of minimum light level are needed, they can also be obtained by determining a ratio for the lamp output value i.e. To ensure a minimum of lux on the centre line of an escape route, a value times greater must be applied to the chart value. So 2000 lumen lamp output gives the same spacing to lux as 200 lumens does for 1 lux. USE OF SPACING TABLES WITH COMPUTER PROGRAMS Computer programs can provide accurate values for specific applications, using data for the exact luminaire, at the precise mounting height and with the actual emergency lamp output, for any luminaire configuration. To quickly develop an initial spacing layout, the spacing values from the nearest table should be used. This can then be applied to the software and modified as required, to obtain the optimum luminaire layout. Illuminance levels can then be calculated, verifying the system design as required by BS52-1:1999 & EN1838.

Central Battery Systems

Central Battery Systems Central battery system based emergency lighting is ideal for medium to large installations. For projects where central control and testing is desirable, a central battery system is a viable and cost effective
