Heat Detector (Model 55000-4501IMC)
HEAT DETECTOR (MODEL 55000-4501IMC)
The heat detector has a common profile with optical smoke detector but has a lower air flow resistance case made of self extinguishing white polycarbonate.
They monitor temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature.
To provide a device for use in ambient temperature up to 55°C, a temperature detector is also available. This has similar characteristics to the standard temperature detector at 25°C but reaches a 55 count (alarm) at 90°C.
- Supply voltage from 17 to 28 Volts DC
- Quiescent current at 250µA average, 500µA peak, surge current at 1mA
- Two wire supply of polarity insensitive
- Operating temperature range from -20°C to +70°C
- Red light emitting diode (LED) as alarm indicator
- Sensitivity range from 25°C to 90°C ( 1°C/Count; -20°C returns to 8 counts)
- 0% to 95% relative humidity with no condensation or icing
- IP rating of 53
- 100mm (Diameter) x 42mm (Height)
- 105g
