Fireboy-Xintex Fixed Heat Detector w/Base [OMHD-04-DB-R]

Fixed Heat Detector with BaseThe 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
