Fire detection and fire alarm systems - Part 31: Multi-sensor fire detectors - Point detectors using a combination of smoke, carbon monoxide and optionally heat sensors
This European Standard specifies requirements, test methods and performance criteria for point-type multi sensor fire detectors for use in fire detection and fire alarm systems installed in and around buildings (see EN 54-1:2011), incorporating in one mechanical enclosure at least one optical or ionization smoke sensor and at least one carbon monoxide (CO) sensor and optionally one or more heat sensors, utilizing the combination of the detected phenomena. This European Standard covers only modes of operation, where at least the signals of both smoke and carbon monoxide sensors are continuously evaluated.
Point detectors using a combination of smoke, carbon monoxide and optionally heat sensors, which are having special characteristics suitable for the detection of specific fire risks are not covered by this European Standard. The performance requirements for any additional functions are beyond the scope of this standard (e.g. additional features or enhanced functionality for which this European Standard does not define a test or assessment method).

Overview
SIST EN 54-31:2015/kFprA1:2015 specifies performance, testing, and construction requirements for multi-sensor point fire detectors used in fire detection and fire alarm systems within buildings. Issued by SIST, this standard covers point-type detectors that integrate at least one optical or ionization smoke sensor and at least one carbon monoxide (CO) sensor, optionally combined with one or more heat sensors in a single device enclosure. The main focus is on systems continuously evaluating both smoke and CO sensor signals to ensure greater reliability in early fire identification and response.
This standard does not cover point detectors with special characteristics specifically tailored for unique fire risks, nor does it set requirements for extra features outside standard detection functionality.
Key Topics
- Device Requirements: Specifies criteria for detectors integrating smoke and CO sensors, with optional heat sensors, ensuring reliable multi-sensor fire detection.
- Test Methods: Outlines required laboratory and performance tests for device functionality, including gas test chambers for CO and heat tunnels for thermal response.
- Performance Criteria: Details the operational requirements such as sensitivity, response thresholds, and resistance to environmental factors.
- Mechanical Construction: Sets standards for protection against ingress of foreign bodies and robustness in typical installation environments.
- Inspection and Adjustments: Requires visual and functional checks for connection of ancillary devices, monitoring of detachable detectors, and on-site adjustment capabilities.
Applications
Multi-sensor fire detectors as defined by SIST EN 54-31:2015/kFprA1:2015 are widely used in:
- Commercial buildings and offices: Enhancing alarm reliability by using combined sensing technologies for smoke and carbon monoxide.
- Public spaces and healthcare facilities: Providing early detection in diverse conditions where different fire types may occur.
- Residential complexes: Improving occupant safety by minimizing false alarms and responding effectively to various fire signatures.
- Industrial and educational facilities: Enabling compliance with European fire safety and emergency requirements.
The integrated, point-type multi-sensor detectors help reduce false alarms by cross-checking multiple sensor inputs, offering robust protection compared to single-phenomenon detectors. This standard ensures the consistency and performance of such devices across their operational lifecycle.
Related Standards
For comprehensive compliance and optimum system integration, consider referencing the following standards alongside SIST EN 54-31:2015/kFprA1:2015:
- EN 54-1:2011 - Overview and application guidelines for fire detection and fire alarm systems.
