This is an application for corridors where doors are often open and for corridors without concealed doors.

Light sources

This application shows an example of fittings with 50 Hz choke operation or non-dimmable HF operating devices.

Positioning of detectors

To achieve optimum detection and a high level of comfort it is important for detectors to be mounted in the correct position. This is particularly important with corridor solutions. Unfortunately one far too often sees detectors aimed at doors and entrances, thus adversely affecting detection.

The optimum direction of detection is when the fields of recognition are crossed at 90°, and the poorest detection is achieved with motion in line with the fields of recognition in either direction. Because of this, a detector using a lens with a 90° opening angle must be selected. It must be mounted in a corner in front of the door so that it is not obscured when the door opens, and must be at the correct height (1.6 – 1.9 m in corridors).

In corridors of up to 40 m, Standard Lens No. 15 is suitable. In long corridors a lens with a long field and a 90° opening angle is suitable, e.g. Lens 41 (see below). There are 40 or so more different lenses to choose from. In long corridors that also have an entrance door at the far end, detection at the entrance may consequently be poor. This is because there is no detection across the fields.

Two detectors may then be needed, mounted diagonally at each end of the corridor (see Application 2E). Correct adjustment is made far easier if the BL-1 field-indication diode (Order No. 13035) is used. This especially applies to long corridors.

Control system

Regarding control of the light sources, with 50 Hz operation and non-dimmable HF devices one is referred to control on the power side, i.e. let the detectors control the contactors. This will cause increased wear to operating devices and light sources. To alleviate this, fittings with 50 Hz operation should be provided with electronic activators of the type Aura Light ‘Strike’ or similar.

For new builds or renovation projects it is very important that you study the applications described in Dynamic lighting control, see applications 2C, 2D and 2E!

Closed corridors/conduits

In closed corridors with doors to other areas shut, use of acoustic technology is the optimum approach, especially if there are nooks and crannies, and when you are looking for things in your cellar store.

Corridors with angles and nooks and crannies

In corridors with angles and screened-off areas, a combination of IR detector and the AD-300 acoustic auxiliary detector is often the optimum solution for maximum comfort. See application example for corridor with IR detector and AD-300 acoustic auxiliary detector. See application 2B and 2D.
