4.4 ENVIRONMENTAL CHARACTERISTICS
4.4.1 GENERAL
The design and construction of the FV300 series detectors are such that they may be used over a
wide range of environmental conditions. Relevant limits are given in Para 4.2.
4.4.2 TEMPERATURE AND HUMIDITY
FV311S/FV312S - models without camera
Operating temperature range: -40°C to +80°C
Storage temperature range: -40°C to +80°C
FV311SC(-N)/FV312SC(-N) - models with camera
Operating temperature range: -10°C to +50°C*
Storage temperature range: -20°C to +70°C
All models
Relative humidity: Up to 99% (non-condensing)
Note: * The detector will turn the camera off if the temperature goes outside this range
but fire detection capability is still present when the video is switched off.
