The IR6003/7 Oil Mist/Smoke Detector from Johnson Controls has been specially designed to be highly sensitive to the presence of oil & kerosene mists or smoke particles in the path of the detector beam.
The detector has been developed for use in enclosed oil rig well head areas, generator rooms and turbine enclosures. The detector automatically compensates for contamination of the detector lenses and signals when a point is reached where further deterioration cannot be tolerated and the lens requires cleaning.
Two levels of alarm status are provided. A low level alarm and a high level alarm. There is also a beam blocked status provided in the event that the beam is interrupted.
The detector monitors the obscuration level within the beam path and when it detects a loss of 0.5 dB due to particles in the air it generates an alarm condition.
If the device detects a sudden high increase in obscuration, a beam blocked status will be set and if the level is maintained for 60 seconds a Beam Blocked status will be reported.
The detector automatically compensates for gradual detector lens contamination and also compensates for more rapid environmental changes (eg. Temperature Change).
