Audio Buzzer 7 3 4 2 6 5 V2.0 11/08 RT30 Operation Detecting Live Circuits (VOLTAGE method) The RT30 can be directly clamped on installed building wiring and will detect the voltage applied to the wiring. 1. Slide the transmitter power switch to the VOLTAGE position. The POWER LED will switch on. 2. Slide the Receiver power switch to the ON position. The POWER LED and the SIGNAL OK LED will switch ON. 3. Place the RomexTM/nm cable (AC wire) directly into the wire clamp slot or, alternatively, connect the external voltage detector probe into the external probe socket and then clamp the probe to any cable, extension cord or appliance cord. 4. If the cable is “live” (voltage present), the VOLTAGE/LIGHT amber LED on the transmitter will switch on and the DETECT LED on the receiver will switch on. 5. If desired, switch the receiver power to switch to the audio OFF position disable the audible tone. 6. When the voltage is removed (by opening the splice or the circuit breaker, for example), the Detect LEDs will switch OFF and the detect beeper will switch OFF. Note: Use of the External Probe overrides the setting of the Power/Mode Switch. The Lighting method cannot be used while the External Probe is attached. 3 RT30 V2.0 11/08 Detecting Live Circuits (LIGHTING method) In situations where access to circuit wiring is limited, the RT30 can also detect room lighting changes (ON to OFF). 1. Slide the transmitter power switch to the LIGHT position. The POWER LED will switch on. 2. Slide the Receiver power switch to the ON position. The POWER LED will switch on. 3. Cover the Light Sensor on the transmitter and press the Light Setpoint button. 4. Expose the Light Sensor to the light source. The VOLTAGE/LIGHT LED on the transmitter and the DETECT LED on the receiver will switch on 5. When the lights are turned off the VOLTAGE/LIGHT LED on the transmitter and the DETECT LED on the receiver will switch off, indicating the light has been switched off and power has been removed. Note: Before use, always test the light on/off operation for proper sensitivity and detection.
