You can choose E2S sounders and beacons to suit your site’s noise levels, lighting and environment. The range includes industrial, marine and explosion-protected models, with different voltages, tones and lens colours.
Ordinary-location, marine and explosion-protected ranges must not be treated as interchangeable even when their output appears similar.
Selection needs both audibility and visual coverage calculations, not only the maximum headline dB or candela value.
Hazardous-area products require the complete gas/dust group, temperature class, zone or division and ambient range to match.
Frequently asked questions
Quick answers
Can I decode any E2S part number here?
You can use this guide to understand selected fields in a D1xB2X05 part number. If you have a different family or an older code, send it to us and we can help you identify it.
Is any red beacon a fire alarm visual device?
No. A red lens doesn’t tell you whether a beacon has the fire-alarm approval or coverage you need. You’ll need a model and configuration listed for that use.
Can I substitute a different supply voltage?
No. Your device’s marked voltage and electrical load, including its starting current, need to match the circuit. We can help you find the right voltage variant.
What do I need to specify for an E2S sounder?
Provide the background noise, listening distance, alarm tone, power supply and installation location. The maximum sound rating alone does not show whether people will hear it throughout the area.
Which E2S model can be used in a hazardous area?
Choose by the area classification and the exact certificate, including gas or dust group, temperature and ambient limits. An explosion-protection marking does not make a device suitable for every location.
What should I send when replacing an E2S device?
Send a clear photograph of the complete nameplate, part number, supply voltage and cable entries. Include the required tone or beacon colour and the installation environment.
