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:
- 163°F 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 360º visibility
- Operating & Storage Temperature: -40ºC to +70ºC
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
