Fixed Heat Detector with Base

The Fireboy-Xintex Heat Detector uses a single thermistor to sense the air temperature around the detector. This heat detector was designed to detect how fast the temperature is increasing.

Features:

  • 163F Fixed Heat Detector
  • Housing: White flame-retardant polycarbonate
  • Terminals: Nickel-plated stainless steel
  • Ideal in environments that are dirty or smoky
  • Unaffected by wind or atmospheric pressure
  • Remote test feature

Specifications:

  • Detection Principle: Measurement of heat using a thermistor
  • Sampling Frequency: Once every four seconds
  • Supply Voltage: 8.5 V dc to 33 V dc
  • Supply Wiring: Two wire supply, polarity sensitive
  • Power-up Time: < 20 seconds
  • Minimum: detector active voltage: 6 V
  • Holding Voltage: 5 V - 33 V
  • Minimum Holding Current: 8 mA
  • Minimum Voltage to Light Alarm LED: 5 V
  • Alarm Reset Voltage: < 1 V
  • Alarm Reset Time: One second
  • Alarm Indicator: Integral indicator with 360 visibility
  • Operating Storage Temperature: -40C to +70C

Operation:

  • Open-web casing that enables air to flow freely across a thermistor which measures the air temperature every two seconds
  • A microprocessor stores the temperatures and compares them with pre-set values to determine whether a fixed upper limit - the alarm level - has been reached
  • Detectors the microprocessor uses algorithms to determine how fast the temperature is increasing

The Fireboy-Xintex OMHD-04-DB-R Fixed Heat Detector is designed to provide reliable temperature monitoring in challenging environments such as industrial settings, boats, or areas prone to dirt and smoke. Utilizing a single thermistor, this detector measures the surrounding air temperature and assesses the rate of temperature increase to trigger an alarm when preset thresholds are exceeded. Its housing is made from white flame-retardant polycarbonate, ensuring durability and safety in various conditions. Nickel-plated stainless steel terminals offer secure electrical connections, making installation straightforward and reliable. The detector's open-web casing allows air to flow freely across the thermistor, ensuring accurate temperature readings every two seconds. An integral alarm indicator with 360-degree visibility provides clear visual alerts, and the remote test feature allows for easy maintenance without disassembly. The device operates over a wide voltage range from 8.5 V DC to 33 V DC, with a fast power-up time of less than 20 seconds, ensuring quick activation when needed. Its sophisticated microprocessor algorithms analyze temperature data to detect rapid increases, which are critical in early fire detection scenarios. The OMHD-04-DB-R is built to withstand extreme temperatures, functioning effectively from -40°C to +70°C, making it suitable for various environments. The detector's design emphasizes safety, reliability, and ease of integration into existing fire safety systems, providing peace of mind in both commercial and residential applications.

Features:

  • 163°F fixed heat detector for early fire detection
  • Housing made from flame-retardant polycarbonate for durability
  • Nickel-plated stainless steel terminals for secure connections
  • Effective in environments with dirt or smoke presence
  • Unaffected by wind or atmospheric pressure variations
  • Remote test feature for easy maintenance
  • Open-web casing enabling free airflow for accurate readings
  • Fast detection sampling every four seconds
  • Wide operating voltage range from 8.5 V to 33 V DC
  • Integral 360-degree alarm indicator for clear visual alerts
  • Operates reliably from -40°C to +70°C
