RT30 V2.0 11/08

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

switch to the audio OFF position to

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.

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.

Maintenance

Battery Replacement

When the Power LED begins to dim, or the transmitter and receiver stop

communicating, the batteries may need to be replaced. Each unit uses two (2)

‘AAA’ batteries (MN2400 or equivalent). The battery doors can be removed

using a Philips screwdriver to loosen the attaching screw.
