Hikvision HF-H2-R Wireless Heat Detector is a wireless fire detection device designed to detect abnormal heat conditions and provide an alarm through a compatible wireless fire alarm system. The HF-H2-R uses an NTC thermistor and supports both fixed-temperature and rate-of-rise heat detection, making it suitable for environments where heat detection is more appropriate than smoke detection.

The Hikvision HF-H2-R uses 433MHz LoRa wireless communication and is designed to work as part of Hikvision’s wireless fire alarm solution. Its heat-based detection approach makes it particularly useful for areas where normal smoke, steam or other environmental conditions could make smoke detection less suitable.

Wireless Heat Detection

The Hikvision HF-H2-R Wireless Heat Detector detects heat rather than smoke particles. This makes it a useful detection option for locations where smoke detectors may not be the most appropriate choice because of normal environmental conditions.

The detector uses an NTC thermistor to monitor temperature changes. It supports fixed-temperature detection at 57°C as well as rate-of-rise detection, allowing the device to respond to different heat conditions.

433MHz LoRa Wireless Communication

The HF-H2-R Heat Detector uses 433MHz LoRa wireless communication as part of Hikvision’s wireless fire alarm system. This allows the detector to communicate wirelessly with compatible system equipment and reduces the need for conventional signal cabling between the detector and gateway.

Hikvision’s wireless fire alarm system is designed for small and medium-sized networked applications, with the LoRa wireless range including smoke and heat detection devices. :contentReference[oaicite:0]{index=0}

NTC Thermistor Sensor

The Hikvision HF-H2-R uses an NTC thermistor for heat detection. The sensor monitors changes in temperature and enables the detector to identify specified heat conditions.

Unlike a photoelectric smoke detector, the HF-H2-R does not rely on smoke particles to initiate detection. This makes it suitable for carefully selected areas where heat detection is preferred as part of the overall fire alarm design.

57°C Fixed Temperature Detection

The Hikvision HF-H2-R Wireless Heat Detector supports fixed-temperature detection at 57°C. When the temperature reaches the specified fixed-temperature condition, the detector can initiate an alarm through the compatible wireless fire alarm system.

Fixed-temperature detection can be useful in areas where the normal environment may contain smoke, dust or steam but a significant increase in temperature needs to be detected.

Rate-of-Rise Heat Detection

In addition to fixed-temperature detection, the HF-H2-R Heat Detector supports rate-of-rise detection. This allows the detector to respond to a rapid increase in temperature rather than depending only on a fixed temperature threshold.

The combination of fixed-temperature and rate-of-rise detection provides flexibility when designing heat-based fire detection for suitable environments.

Ideal for Areas with Smoke or Steam

The Hikvision Wireless Heat Detector can be considered for locations where normal smoke or steam may make smoke detection less suitable. Heat detection can provide an alternative approach when selected according to the fire characteristics and environmental conditions of the area.

Potential applications can include kitchens and other areas where normal activities may produce steam or airborne particles. The exact detector type should always be determined through an appropriate fire risk assessment.

Wireless Fire Alarm System Integration

The Hikvision HF-H2-R is designed as part of Hikvision’s wireless fire alarm ecosystem. The detector communicates wirelessly with compatible system equipment and can be incorporated into an appropriately configured wireless fire detection installation.

Hikvision’s wireless fire safety range includes compatible detection and alarm devices, allowing different types of detectors to be used according to the requirements of individual areas within a building.

Benefits of Wireless Installation

A 433MHz Wireless Heat Detector provides greater installation flexibility than a conventional wired heat detector in suitable applications. Wireless communication can be useful in existing buildings, renovated premises and locations where installing new fire alarm cables would be difficult.

Wireless signal coverage should be assessed before installation because building construction, walls, floors and other environmental factors can affect wireless communication.

Ceiling-Mounted Design

The Hikvision HF-H2-R Wireless Heat Detector is designed for ceiling-mounted installation. Correct positioning allows the detector to monitor heat conditions within the protected area effectively.

The installation position should follow the manufacturer’s instructions and the overall fire alarm system design. Areas containing unusual or permanent heat sources should be assessed carefully before selecting the installation location.

Suitable Applications

The HF-H2-R Wireless Heat Detector can be considered for suitable indoor areas where heat detection is appropriate, including:

• Kitchens and cooking areas
• Areas with normal steam
• Locations with airborne dust
• Workshops
• Industrial environments
• Commercial premises
• Warehouses and storage areas
• Other suitable areas where heat detection is preferred

The final detector selection should be based on the building’s fire risk assessment and applicable fire safety requirements. A heat detector should not automatically replace a smoke detector where smoke detection is required.

Heat Detector vs Smoke Detector

The Hikvision HF-H2-R is a heat detector, while a smoke detector is designed to detect smoke particles. Choosing between these two technologies depends on the environment and expected fire characteristics.

For example, areas with significant steam or dust may require a heat-based detection solution to reduce the likelihood of unwanted alarms caused by normal environmental conditions. Other areas may require smoke detection for earlier detection of certain fire types.

Part of Hikvision Fire Safety Range

The Hikvision Wireless Heat Detector is part of Hikvision’s wireless fire safety product family. Available product information lists the HF-H2-R alongside the HF-S3-R wireless smoke detector and other wireless fire alarm components. :contentReference[oaicite:1]{index=1}

This allows a suitably designed installation to combine heat and smoke detection according to the requirements of different areas within a building.
