Prolojik lighting control is widely used in London offices for presence detection, daylight dimming and scene control. Like any networked system, it relies on every sensor and controller keeping its power, its connection and its address. When one of those drops out, part of the office stops behaving as it should.
We maintain Prolojik systems in occupied offices, including a Mayfair office where we work under an annual service contract. These are the jobs that come up most often.
A PIR that has stopped working
Presence detectors (PIRs) are the parts people notice first. If one fails, lights in that area may stay off when someone walks in, or stay on after everyone has gone home.
On a recent visit the PIR had simply lost power. Once power was restored it still wasn’t communicating. We tried to re-address it on site, but it wouldn’t take an address, so we fitted a new Prolojik PIR and gave it the existing device address. That way it slotted straight back into the existing configuration, with no reprogramming of the rest of the floor.
Tip: we take a replacement sensor on investigation visits. If the old one can be saved, the spare is left on site as stock. If it can’t, the job is finished in one visit instead of two.
A wing or area controller offline
When a whole wing or zone stops responding, the cause is usually a controller that has lost power or communication rather than the individual fittings. We check supplies, connections and the network back to the controller, then restore it and test the zone.
DALI drivers, ballasts and emergency inverters
Many Prolojik installations control DALI fittings. Over time, drivers, ballasts and emergency inverter units fail, and they need replacing with compatible parts and addressing into the system. On our service visits we replace these to the floor plan, so the client’s records stay accurate.
Local work on site, programming remotely
Some changes need Prolojik’s own software. On those jobs we do the local work on site, such as wiring, replacing devices and addressing, and Prolojik can then programme remotely. You get the manufacturer’s expertise without paying for a second team to travel.
Why a service contract helps
A planned service contract means someone checks the system regularly, keeps spares to hand and knows the building when something goes wrong. Reactive visits are faster because the engineer already knows where the controllers, risers and floor plans are.
