Explosion Proof Signalling & Emergency Lights
Manual call points, status lights, beacons and push buttons are safety-critical in any hazardous facility — and every one of them needs the same ATEX/IECEx protection as our lighting range, covered in our ATEX lighting guide. Here’s what explosion proof signalling lights do and how to specify them correctly.
What Are Explosion Proof Signalling Devices?
Signalling devices communicate status, alarms or emergency instructions in areas where flammable gases, vapours or dust may be present. Because they’re often mounted directly in process areas — unlike lighting, which can sometimes be positioned further from the highest-risk zone — they carry the same strict ATEX/IECEx certification requirements as any other hazardous-area fixture.
Common Device Types
- Manual call points — operator-activated alarm triggers for fire or emergency response. Browse manual call points.
- Manual push buttons — used for emergency stop, isolation or process signalling functions.
- Status/signal lights — visual indicators for process, equipment or area status.
- Beacons — rotating or flashing warning lights for alarm conditions or vehicle/crane warning.
- Sounder horns — audible alarms, often combined with beacons for dual visual/audible warning.
What to Check Before You Specify
- Zone and gas/dust group — matched to the exact area classification, not a generic “Ex” label.
- Housing material — GRP (glass-reinforced plastic) and stainless steel are common for corrosion resistance in oil & gas and marine environments.
- Visibility/audibility — beacon colour and sounder decibel rating suited to ambient noise and lighting conditions on site.
- Integration — compatibility with your existing fire and gas detection or PLC signalling system.
Explosion Proof Signalling FAQs
Do manual call points need the same ATEX rating as lighting?
Yes — any device installed in a classified hazardous area, including manual call points, push buttons and beacons, must carry certification matched to that zone.
What’s the difference between a beacon and a status light?
Beacons are typically rotating or flashing warning indicators for alarm conditions; status lights are steady or simple-flash indicators showing equipment or process state.
Can sounders and beacons be combined in one unit?
Yes, combined sounder-beacon units are common where both audible and visual warning is required from a single point.
What housing material is best for offshore installations?
Stainless steel or marine-grade GRP housings are typically specified for offshore and coastal sites due to corrosion resistance.
