Fire Alarm Loudspeakers (Voice Evacuation) are subject to mandatory BIS ISI certification under the Fire Detection and Alarm Systems (Quality Control) Order, 2026. From 6 mo after publication of the QCO in the e-Gazette, these products cannot be lawfully manufactured for sale, imported, or distributed in India without a valid BIS ISI licence under IS/ISO 7240-24:2016. Non-compliance attracts penalties under the BIS Act, 2016 — product seizure, fines, and prosecution.
This guide covers the applicable Indian Standard, key technical and safety requirements, the step-by-step certification process, documentary requirements, and the most common compliance pitfalls for manufacturers and importers.
📜 Applicable Indian Standard
- IS/ISO 7240-24:2016 — Fire Alarm Loudspeakers (Voice Evacuation) (primary standard)
- Aligned with the corresponding IEC / ISO standard for technical performance and safety
- Latest amendments notified by BIS apply automatically
📌 Modern voice-evacuation systems save lives — but only if loudspeakers are reliable under fire conditions. The QCO enforces acoustic performance, thermal endurance, and durability across India's commercial and public-space evacuation systems.
🔬 Key Quality Requirements Under IS/ISO 7240-24:2016
BIS-approved laboratories evaluate the following during type testing:
Acoustic Performance
Sound pressure level (SPL), frequency response, and speech intelligibility (STI) verified per ISO 7240-24.
Thermal Endurance
Loudspeakers must continue functioning under elevated temperatures long enough to broadcast evacuation messages.
Mechanical Durability
Vibration, impact, and IP-rating compliance for indoor and outdoor mount types.
Marking & Documentation
Rated power, SPL, frequency response, IP rating, and ISI Mark plus licence number on the loudspeaker.
Products covered under IS/ISO 7240-24:2016:
- Wall-mount fire alarm loudspeakers for offices and corridors
- Ceiling-mount voice-evacuation speakers for indoor spaces
- Horn speakers for outdoor and high-noise environments
- Cabinet and pendant speakers for malls, airports, and stadiums
📋 Step-by-Step BIS ISI Certification Process
- Variant ScopingList every model, mount type, power rating, and IP rating. Each unique construction may need separate sample testing.
- Application FilingSubmit online application on manak.bis.gov.in. Indian manufacturers via Product Certification Scheme; foreign manufacturers via FMCS with appointed AIR.
- Sample TestingSubmit complete loudspeakers to a BIS-recognised fire-detection laboratory. Acoustic, thermal endurance, and mechanical tests: approximately 4–6 weeks.
- Factory InspectionBIS officers inspect transducer assembly, enclosure manufacturing, and in-house testing capability.
- Licence GrantBIS issues the ISI Mark licence. ISI Mark plus licence number is applied on the loudspeaker and packaging.
- Surveillance & RenewalPeriodic BIS market sample testing, factory audits, and annual marking fees keep the licence active.
📄 Documents Required
- Company incorporation / registration certificate
- Product list with power, SPL, frequency response, IP rating
- Engineering drawings and BOM with transducer specs
- Acoustic test data and thermal endurance documentation
- EMC test plan and product safety documentation
- Quality Manual / ISO 9001 certificate (if available)
- AIR appointment letter (for foreign manufacturers)
- Existing test reports from BIS-recognised labs (if any)
⚠ Common Compliance Pitfalls
Common issues include SPL shortfall, speech intelligibility below ISO limits, thermal endurance failure, and incomplete marking of IP rating and frequency response.
🏭 Special Considerations for Importers
Fire alarm loudspeakers are imported in volume from Europe, the US, and China. Each variant requires its own BIS ISI certification. Voice-evacuation integrators must hold valid BIS documentation before installation.
