SECTION 2 Installing STE-8000 sensors This section provides important instructions and guidelines for installing the STE-8000 series sensors. Carefully review this information before installing the controllers. Installing the sensors includes the following topics that are covered in this section.
Installing STE-8000 sensors Rough-in preparation KMC Controls False detections may be triggered by: ◆ ◆ ◆ Rough-in preparation The temperature inside the detection range suddenly changes because of the entry of cold or warm air from an air-conditioning or heating unit. The sensor being directly exposed to sunlight, an incandescent light, or other source of far-infrared rays. Small animal movement. Complete rough-in wiring at each sensor location prior to sensor installation.
STE-8001 and STE-8201 sensors Installing STE-8000 sensors Maintenance 4. Insert the Ethernet cable coming from the base into the sensor. 5. Place the top of the sensor over the top of the mounting base and swing it down over the Allen screw brackets. Be careful not to pinch any wiring. 6. Back the Allen screws out of the brackets until they engage the sensor cover and hold it in place. Maintenance Revision A Remove dust as necessary from holes in top and bottom.
