Point-Type Fire Detectors (Carbon Monoxide + 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 7240-8:2014. 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 7240-8:2014 — Point-Type Fire Detectors (Carbon Monoxide + Heat) (primary standard)
- Aligned with the corresponding IEC / ISO standard for technical performance and safety
- Latest amendments notified by BIS apply automatically
📌 CO + heat combination detectors offer earlier fire detection and dramatically reduced false alarms compared to smoke-only detectors. The QCO ensures dual-sensor performance and reliability across residential and commercial applications.
🔬 Key Quality Requirements Under IS/ISO 7240-8:2014
BIS-approved laboratories evaluate the following during type testing:
CO Sensor Performance
CO sensitivity, response curve, and false-alarm rejection per ISO 7240-8. Cross-sensitivity to common household gases verified.
Heat Sensor Performance
Heat-rise response, fixed-temperature alarm point, and combined CO + heat logic per ISO 7240-8.
Environmental Durability
Temperature, humidity, vibration, and EMC immunity. Long-term sensor stability tested.
Marking & Documentation
Detector class, alarm thresholds, operating temperature range, and ISI Mark plus licence number on the housing.
Products covered under IS/ISO 7240-8:2014:
- Residential CO + heat detectors for homes and apartments
- Commercial dual-sensor detectors for offices and retail
- Hospitality and hotel detectors for guest rooms
- Healthcare facility detectors for care homes and hospitals
📋 Step-by-Step BIS ISI Certification Process
- Sensor Combination MappingIdentify the CO + heat combination logic. Each detector class requires separate testing under ISO 7240-8.
- 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 testing laboratory. CO, heat, and environmental 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 detector classes and sensor combinations
- Engineering drawings and BOM with sensor specs
- Sensor calibration records and combination-logic 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 CO sensor drift over time, heat sensor response shortfall, false-alarm under cooking-source CO, and incomplete marking of detector class.
🏭 Special Considerations for Importers
CO + heat detectors are imported for India's residential and commercial fire-safety market. Each detector class requires its own BIS ISI certification. Hospitality and healthcare project EPCs increasingly require ISI marking.
