The circuit drives a two-coil latching relay (Figure 2) . When the latching relay is engaged, full AC power is connected to the load. The LS6506R draws its power from the AC hot line and the houseground connection that is located in a standard wall box. The maximum current draw from the ground line is 500µA RMS. The LS6507R draws its power from the AC HOT and AC NEUTRAL lines. All timing is generated from the AC input.\u003Cbr>The circuit contains a two stage PIR amplifier. The sensitivity can be adjusted by replacing R5 in Figure 2 with a potentiometer. Upon power up all inputs are disabled for a period of 56 seconds (60Hz operation) or 67 seconds (50Hz operation) in order for the PIR amplifier to reach its quiescent operating state. The circuit contains two operating modes. Refer to Figure 5 for State Diagrams.\u003Cbr>Operation for Mode 1 is as follows:\u003Cbr>Refer to Figure 2. The IC will power up in the Off-State, S0 . A momentary pressing of the pushbutton switch SW1,  or occupancy detection, will cause a negative-going output pulse, LR1, to occur and turn on the light and place the IC in the On-State, S1 . If occupancy is not detected, a negative-going output pulse, LR2, will cause the lights to turnoff after a time-out of 5, 10, 20 or 30 minutes, or 30 seconds, as selected by a potentiometer control at the Timer Control input. If occupancy is detected before time-out occurs, the selected time-out begins again. If time-out occurs and the lights switch off, then occupancy detection, or pressing the pushbutton switch, will switch the lights back on again. Once the unit is in S1 , pressing the On/Off push-button switch places the unit in the Off-State, S2 , and turns the lights off and keeps them off as long as motion is detected, or if motion is not detected the lights will stay off for the time-out period. At the end of the time-out period, the unit will revert to S0 . Whether the lights are on or off, detected motion will cause the LED indicator light to blink. | Operation for Mode 2 is as follows:\u003Cbr>In this mode, lights can only be turned on by pressing the On/Off pushbutton. Lights will remain on if occupancy is detected. Lights will turnoff automatically when occupancy no longer exists and the time-out occurs . Lights can also be turned off by pressing the On/Off pushbutton.\u003Cbr>Operation for Mode 3 is as follows:\u003Cbr>In this mode, Pins 10 and 12 are connected together. One momentary switch is used instead of the two as shown in Figures 2 and 3. Lights can be turned on by pressing the momentary pushbutton or by occupancy detection. Lights will remain on if occupancy is detected. Lights will turn off automatically when occupancy no longer exists and the time-out occurs. Lights can also be turned off by pressing the momentary pushbutton.\u003Cbr>Refer to the application schematic of Figure 2: Whenever the momentary switch SW1 is pressed,","cbCaifKizf9sjrtI","https://ap.wps.com/l/cbCaifKizf9sjrtI","pdf",240442,12,"English","# FEATURES\n## DESCRIPTION\n## Operating Modes (Mode 1-3)\n## Manual Controls, Timing and Indicators\n## Ambient Light Override and Calibration\n## Relay and Triac Application Details","[{\"question\":\"What are the main functions of the LS6506R and LS6507R circuits?\",\"answer\":\"They detect room occupancy using a PIR amplifier and switch AC loads.
