Fire Exit Signs

An emergency exit sign shows the way out along an escape route and keeps lighting it when the mains supply fails. This page has Duceri exit boxes in surface, slimline, bulkhead and hanging styles with up, down, left and right legends, and Knightsbridge LED exit signs for wall, ceiling or suspended mounting, in maintained, non-maintained and self-test versions, with 2W to 4W LED light sources.

Choosing Fire Exit Signs

Decide how the sign will be mounted, which way its arrow must point, and how it will be tested.

Mounting style

Surface exit boxes fix flat to a wall: the Duceri D120 series are 3W LED boxes with finishes including black, brass, chrome and white. The D121AWH and D121SAWH are slimline surface boxes, and the D151AWH is an IP65 bulkhead exit sign. For a sign hung from the ceiling, the double-sided D330AWH and D330SAWH have a polycarbonate frame, and the Knightsbridge EMLSUSL has a drop that adjusts to a maximum of 800mm including its legend. The EMEXITL uses a hanger and hinge system for wall or ceiling mounting.

Legends

The arrow must point along the route from where the sign is seen. Duceri D120 boxes are made with one fixed down, left, right or up legend, so pick the version for the direction needed, while the All Legends D121AWH and D330AWH cover any direction. The Knightsbridge EMRNSTL has interchangeable legends, with arrow up, down and left/right legends included.

Operation and testing

A maintained sign is lit whenever the mains is on, a non-maintained sign lights when the mains fails, and the Duceri D120DBK switchable box has maintained and non-maintained operation. Self-test signs run their own checks at set intervals: the Knightsbridge EMXSTL has a self-test facility complying with EN 62034, and Duceri self-test boxes include the D120SDWH and D520DWH.

Frequently asked questions

What is the difference between a maintained and a non-maintained exit sign?

A maintained sign stays lit whenever the mains is on and carries on from its battery in a power cut, while a non-maintained sign lights up when the mains fails. The Duceri D120DBK and D151AWH have maintained and non-maintained operation, and the Knightsbridge EMEXITL and EMLSUSL can be wired either way.

Can I change the arrow direction on an exit sign?

Yes, on a sign with interchangeable legends. The Knightsbridge EMRNSTL has arrow up, down and left/right legends included to swap on site. Duceri D120 exit boxes are made with one fixed legend, so choose the D120D, D120L, D120R or D120U version for the route, and the D121AWH and D330AWH have all legends.

What is a self-test exit sign?

A sign that tests itself at set intervals and shows the result, so fewer manual checks are needed. The Knightsbridge EMXSTL has an integral self-test facility to EN 62034 with visual health-check LED indicators, and Duceri self-test models include the D120SDWH surface box, the D121SAWH slimline box and the D330SAWH hanging sign.

How long does an exit sign stay lit in a power cut?

The EMEXITL gives a minimum illumination time of up to 3 hours, the EMLSUSL and EMRNSTL give 3 hours of emergency operation, and the EMXSTL a minimum of 3 hours. The Duceri D120DBK has a lithium battery with charge and discharge protection.

Can an exit sign hang from the ceiling?

Yes, hanging and suspended signs are made for it. The Duceri D330AWH and D330SAWH are double-sided hanging signs with a polycarbonate frame, so the legend faces both ways, and the Knightsbridge EMLSUSL is a double-sided suspended sign whose drop adjusts to a maximum of 800mm including the legend. The EMEXITL and EMXSTL fit a wall or a ceiling.

Is there an exit sign for damp areas?

Yes, the Duceri D151AWH is a 3W LED bulkhead exit sign rated IP65, with all legends, a lithium battery and maintained or non-maintained operation. Most of the other signs here are IP20, which suits dry indoor positions, so choose the IP65 bulkhead where the sign may be exposed to moisture.

What finishes are the Duceri exit boxes made in?

The Duceri D120 surface exit boxes are made in black, brass, chrome and white, so a sign can match other fittings in a building. Examples are the D120DBK in black, the D120LBR in brass, the D120RCH in chrome and the D120DWH in white. The Duceri slimline, bulkhead and hanging signs here are white.

How much power does an LED exit sign use?

Between 2W and 4W for the signs on this page. The Duceri exit boxes are 3W LED fittings, the Knightsbridge EMEXITL, EMRNSTL and EMXSTL are 4W, and the suspended EMLSUSL is 2W. Duceri D120 boxes such as the D120LBK use 20 SMD 2835 LEDs, and the slimline D121SAWH gives 48 lumens on mains and 36 lumens in emergency mode.

What battery does an emergency exit sign use?

A rechargeable battery kept charged from the mains. The Knightsbridge EMEXITL, EMRNSTL and EMLSUSL use LiFePO4 batteries, and Duceri boxes such as the D120LBK have a lithium battery with charge and discharge protection and a green LED charging indicator. Keep the supply to a maintained sign switched on so the battery stays charged.
