Advanced Rate-of-Rise Heat Detector

The Fireboy-Xintex Advanced Rate-of-Rise Heat Detector employs a state-of-the-art thermistor to accurately monitor the temperature fluctuations in its surrounding environment. This innovative heat detector is engineered to identify rapid temperature increases, making it ideal for high-risk areas.

Key Highlights:

• Designed for timely response to rising heat conditions
• Robust white flame-retardant polycarbonate housing
• Durable nickel-plated stainless steel terminals
• Effective in environments subject to dust or smoke
• Operates independently of wind or barometric pressure
• Features a remote testing capability for convenience

Technical Specifications:

• Detection Method: Utilizes a thermistor for heat measurement
• Sampling Interval: Every four seconds
• Input Voltage: 8.5 V dc to 33 V dc
• Wiring Configuration: Two-wire, polarity-sensitive setup
• Power On Duration: Less than 20 seconds
• Minimum Operating Voltage: 6 V
• Applicable Voltage Range: 5 V to 33 V
• Minimum Current Requirement: 8 mA
• Voltage to Activate Alarm LED: 5 V
• Alarm Reset Threshold: Below 1 V
• Alarm Reset Duration: One second
• Alarm Notification: 360-degree visible indicator
• Temperature Range: Operating and storage from -40°C to +70°C

Operational Overview:

• Features an open-web design to facilitate airflow across the thermistor, allowing continuous monitoring of ambient temperature.
• A microprocessor records temperature data and compares it against predetermined thresholds to detect alarm conditions.
• Advanced algorithms are employed to assess the rate of temperature escalation accurately.
