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
EN 54-31:2014/FprA1:2015 is a CEN European Standard amendment for multi-sensor point fire detectors. It specifies requirements, test methods and performance criteria for detectors that combine at least one optical or ionisation smoke sensor and a carbon monoxide (CO) sensor, with optional heat sensors, all housed in a single enclosure. The standard applies to devices used in fire detection and fire alarm systems installed in and around buildings (see EN 54-1:2011). A key operational requirement is that smoke and CO signals are continuously evaluated in the detector decision logic.
Key Topics and Requirements
- Sensor combination and enclosure: Defines the multi-sensor configuration (smoke + CO ± heat) and mechanical enclosure requirements.
- Performance criteria and test methods: Specifies how detectors must be tested for detection thresholds, response behaviour and cross-sensitivity.
- Continuous evaluation: Requires simultaneous, continuous evaluation of both smoke and CO sensors for the modes covered by this standard.
- Excluded devices and functions: Devices with special characteristics tailored to specific fire risks are excluded, as are additional functions for which test/assessment methods are not defined.
- Manufacturing and on-site checks: Visual inspection requirements for connection of ancillary devices, monitoring detachable detectors, manufacturer's adjustments and on-site adjustment of response behaviour.
- Protection and robustness: Requirements and inspections for protection against ingress of foreign bodies.
- Test and verification annexes: Normative test apparatus and procedures are defined or amended, including:
- Gas test chamber for CO response threshold and chemical cross-sensitivity (laminar flow velocities: 0.2 ±0.04 m/s or 1.0 ±0.2 m/s).
- Heat tunnel specifications (board thermal conductivity ≤ 0.52 W/(m·K); air-temperature measurement time constant ≤ 2 s at defined flow).
- Apparatus for dazzling test, open wood fire (TF1), glowing smouldering cotton fire (TF3), low temperature black smoke (TF8) - used to characterise detector responses.
Note: Amendment FprA1 modifies clauses and annexes of EN 54-31:2014 (for example Clause 6 on AVCP is deleted and clauses renumbered).
Applications
- Manufacturers: Product design, type testing and CE marking of multi-sensor point detectors.
- Test laboratories and certification bodies: Implementing the specified test methods and annex procedures.
- System designers and integrators: Selecting detectors for buildings where enhanced discrimination between smoke, CO and heat signals improves detection reliability and reduces false alarms.
- Specifiers, procurement and compliance teams: Ensuring products meet EN 54-31 requirements and integrate with EN 54-1 fire alarm systems.
Related Standards
- EN 54-1:2011 - framework and general requirements for fire detection and fire alarm systems (referenced in EN 54-31).
