Commercial Lighting Controls for Workplaces Across Scotland

WB can install and commission suitable occupancy and presence sensors, PIR and microwave detectors, absence controls, photocells, daylight dimming, timers, time clocks, zoning, contactors, local switches, manual overrides, all-off functions and compatible DALI-based arrangements. The final choice depends on the fittings, drivers, circuits, space, task, operating pattern and level of central control required.

PIR devices respond to changes in infrared energy and generally depend on a suitable view of movement. Microwave sensors emit and detect radio-wave reflections, which can help in some high-bay or obstructed areas but may also detect movement beyond the intended boundary, depending on the product and construction. Presence control normally switches on automatically and off after vacancy. Absence control requires a manual-on action and then switches off automatically. WB selects and tests the method for the actual space.

Often, yes. Standalone sensors, timers, photocells, contactors or local zones can be retrofitted where the existing fittings, drivers, switching, wiring and loads are suitable. Dimming may require compatible drivers and control wiring, and some older or mixed equipment can make selective replacement more dependable. The survey should distinguish what can be retained from what needs alteration.

The control sequence is based on how people move and work, then proved on site. Sensor type, detection pattern, mounting height, location, sensitivity, time delay, dim-to-background level, zone size and manual override all matter. A representative room, aisle or bay can be piloted before a wider rollout, and settings can be adjusted after genuine user feedback rather than leaving staff to bypass the system.

WB can undertake agreed installation, alteration and commissioning of suitable common DALI-based lighting controls. DALI-2 includes standardised input-device categories for occupancy and light sensors. Where lighting must connect to a BMS, WB can define and complete the agreed electrical interface and coordinate testing with the BMS provider. Proprietary head-end software, manufacturer-only access, advanced analytics and entertainment or show-control programming need the relevant specialist and a clearly assigned responsibility.

Yes, where the interface has been deliberately engineered. Normal controls must not defeat the required emergency-lighting operation. If selected lighting also uses a backup or standby supply, the load, required operating duration, essential-circuit priority, changeover method, control state after transfer and restoration sequence need to be established. Emergency-lighting installation and testing remain separately defined scopes.

There is no responsible single percentage for every site. The opportunity depends on the connected lighting load, current run hours, occupancy, useful daylight, zoning, tariffs and final settings. WB can document the baseline and proposed sequence, estimate avoided run hours or reduced output with stated assumptions, and compare options. Actual performance should be reviewed after commissioning rather than presented as a guaranteed saving.

Yes. WB can investigate failed or badly positioned sensors, nuisance operation, unsuitable time delays, drifting timers, incorrect zones, failed contactors, incompatible drivers, control wiring and agreed DALI-based faults. Where proprietary software, licences or manufacturer access are required, the scope will identify what WB can complete and what needs the original controls specialist. Existing controls can also be included in planned lighting maintenance.
