Emergency Lighting

Use maintained where a sign or light must be lit whenever the building is occupied, and non-maintained where it needs to come on just when the mains fails. Many fittings here can be set up either way, including the Knightsbridge EMRUN, EMSWING and EMLED1L and the Duceri D1011WH, so the choice can be made on site.

The Knightsbridge EMLED1L, EMTWINLIP and EMLSUSL give a minimum of 3 hours, and the Hochiki N89-O complies with the BS 5266 required 3 hour duration. The EMLED5L self-test bulkhead also gives a minimum of 3 hours. Confirm the duration your fire risk assessment calls for before choosing a fitting.

It runs its own function and duration tests at set intervals and shows the result on an indicator, so routine checks become a walk-round instead of manual tests fitting by fitting. The Knightsbridge EMXSTL, EMPOWERSTL and EMLED5L have a self-test facility to EN 62034, and the TNXTST gear tray runs automatic function and duration tests.

With a key switch that cuts the supply to the emergency circuit so the fittings run on battery. The Duceri EMTS is key activated with 4 pre-programmed test intervals and LED indication for duration tests, and the EMTSLCD adds an LCD display. The EMTSK is a pack of 2 spare keys, and the Knightsbridge GDKEY is a pack of 10 test keys.

The one that points along the escape route from where the sign is seen: an up arrow for straight ahead or through the door beyond, and left, right or down arrows where the route turns. Knightsbridge sells running-man legends for the EMRUN in each direction, such as the EMRUND and EMRUNL, and ESP sells up, down, left and right plates for Duceri exit boxes.

Yes, with a conversion kit matched to the fitting. The EMGUKIT1 adds an inverter and battery to a GU10 fitting through a 55mm cut-out, and the SPKEVEMKIT suits SpektroLED Evo downlights. Philips kits pair an emergency LED driver with a LiFePO4 battery, with one type for linear luminaires and one for recessed panels and downlights.

Yes, with the battery the maker specifies. Duceri lithium iron phosphate cells include the D001 at 3.2V 1500mAh and the D002 at 3.2V 6000mAh, and its Ni-Cd replacements include the EMBAT3.6V1800SER2, compatible with the EMST3WMSDL and EMLED3WMBULK. The Hochiki EL-BAT-450 suits FIREscape luminaires and exit signs.

A corridor lens throws light along a narrow route, while an open lens spreads it more evenly over a room. The Duceri D2411WH has a corridor lens and the D2413WH an open lens, the D5403WH takes either lens, and the Knightsbridge EMPOWER4 and ENM5C include a corridor lens accessory.

A system in which the luminaires and exit signs report to a control panel, so tests and faults are monitored centrally rather than checked fitting by fitting. The Hochiki N89-O and EL-40 are addressable devices that fit the Hochiki YBN-R/3 mounting base, and the EL-BAT-450 battery for FIREscape luminaires has a microchip that lets the FIREscape system monitor its power level.

On the wall above the door or hung from the ceiling. The Knightsbridge EMLSUSL is a double-sided suspended sign typically installed above doorways, with an adjustable drop. CQR BL/310 blade signs mount on the wall or surface as standard, with recessed, flag and suspension kits such as the BL/310/SUSKIT/WH.
