BS EN 50131-2-3:2022

What is this BS EN 50131‑2‑3 - Requirements for microwave detectors about?

BS EN 50131‑2‑3 discusses alarm systems and intrusion and hold-up systems with a focus on requirements for microwave detectors.

BS EN 50131‑2‑3 is the second part of the multi-series on alarm systems that are for microwave detectors installed in buildings and provides for security grades 1 to 4, specific or non-specific wired or wire-free detectors, and uses environmental classes I to IV.

The grade-dependent requirements of BS EN 50131‑2‑3 apply and it is essential that a detector fulfils all the requirements of the specified grade. Functions additional to the mandatory functions specified in BS EN 50131‑2‑3 are included in the detector, providing they do not influence the correct operation of the mandatory functions.

Note 1: Requirements for system interconnections are not included in BS EN 50131‑2‑3.

Note 2: BS EN 50131‑2‑3 does not include requirements for detectors intended for use outdoors.

Who is BS EN 50131‑2‑3 - Requirements for microwave detectors for?

BS EN 50131‑2‑3 on requirements for microwave detectors is useful for:

• Microwave detectors manufacturers
• Manufacturers of intrusion and hold-up systems
• Manufacturers of intrusion detectors devices
• Manufacturers of shock detectors devices
• Alarm receiving centers (ARC)
• Product designers and engineers

Why should you use BS EN 50131‑2‑3 - Requirements for microwave detectors?

A microwave motion detector is a device that uses Doppler radar to detect and measure the movement of an object.

The detection performance tests required for a detector will depend on the coverage angle claimed. Therefore BS EN 50131‑2‑3 differentiates between detectors with coverage angles less than or equal to 180°, such as those typically used for wall-mounted applications and detectors with coverage angles of 360° detectors intended for ceiling mounting.

BS EN 50131‑2‑3 deals with microwave detectors (to be referred to as the detector) used as part of intrusion alarm systems installed in buildings. BS EN 50131‑2‑3 includes four security grades and four environmental classes.

BS EN 50131‑2‑3 provides a purpose of the detector is to emit microwave signals and analyse the signals that are returned to detect an intruder and to provide the necessary range of signals or messages to be used by the rest of the intrusion alarm system.

With obedience and compliance to BS EN 50131‑2‑3, you can enhance microwave detectors’ effectiveness and efficacy and manufacture a standardized product.
