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
