3. Using Table 3, adjust the receiver’s sensors vertically and horizontally until the best possible voltage output is achieved. Table. 3: Voltage Output Voltage Output <1.1V 1.1~1.4V 1.4~1.7V 1.7~2.0V >2.0V Alignment Quality No Signal Poor Good Strongest ® SECO-LARM U.S.A.
* This is the minimum time interval between breaking of both beams which will trigger the output. Setting the interval longer will reduce false alarms from birds or falling leaves, etc., while setting it shorter will detect faster moving objects. ® SECO-LARM U.S.A.
