Point-Type Fire Detectors (Smoke + CO + Optional Heat) 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 7240-27:2018. 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 7240-27:2018 — Point-Type Fire Detectors (Smoke + CO + Optional Heat) (primary standard)
- Aligned with the corresponding IEC / ISO standard for technical performance and safety
- Latest amendments notified by BIS apply automatically
📌 Multi-sensor detectors are the premium category of fire detection — combining smoke, CO, and heat for unmatched reliability and minimal false alarms. The QCO ensures every sensor and combination logic performs to spec across critical facilities.
🔬 Key Quality Requirements Under IS/ISO 7240-27:2018
BIS-approved laboratories evaluate the following during type testing:
Individual Sensor Performance
Smoke, CO, and heat sensors each tested individually against their respective ISO 7240 part requirements.
Combination Logic
Multi-criteria decision logic verified — smoke + CO + heat combinations and their alarm thresholds per ISO 7240-27.
Environmental Durability
Temperature, humidity, vibration, and EMC immunity. Long-term sensor stability tested.
Marking & Documentation
Detector class, sensor combination, alarm thresholds, and ISI Mark plus licence number on the housing.
Products covered under IS/ISO 7240-27:2018:
- Smoke + CO dual-sensor detectors for low-false-alarm applications
- Smoke + CO + heat triple-sensor detectors — premium multi-criteria
- Hospitality and commercial detectors for hotels and offices
- Critical-facility detectors for hospitals, data centres, museums
📋 Step-by-Step BIS ISI Certification Process
- Sensor Combination ScopingList every sensor combination — dual or triple — and the corresponding alarm logic. Each combination requires separate 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 detectors to a BIS-recognised fire-detection laboratory. Individual sensor, combination, and EMC tests: approximately 5–7 weeks.
- Factory InspectionBIS officers inspect sensor assembly, calibration, electronics manufacturing, and in-house testing capability.
- Licence GrantBIS issues the ISI Mark licence. ISI Mark plus licence number is applied on the detector housing 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 sensor combinations and detector classes
- Engineering drawings and BOM with sensor specs
- Combination-logic documentation and calibration records
- 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 combination-logic mis-trigger, individual sensor sensitivity drift, long-term stability shortfall, and incomplete documentation of the alarm-logic decision table.
🏭 Special Considerations for Importers
Multi-sensor detectors are imported for premium projects — hotels, data centres, hospitals. Each combination requires its own BIS ISI certification. High-end project EPCs require ISI marking as a baseline supplier criterion.
