Current Loop 1 (RMA-CL1-SEN)
Installation Note
AVTECH’s Current Loop monitors the electrical current flowing through a single-phase
powered cable. It outputs a signal of 0 to 5 VDC (volts of direct current), which your built-in or
external Room Alert Analog Sensor then converts into an amp (A) reading. By pairing a Current
Loop with your Room Alert monitor, you can easily determine
the power consumption of an electrical appliance / device.

• One (1) Installation Note (You’re reading it now.)
Select An Input Range
Your Current Loop arrives with its jumper set on the largest input amperage range: 0 to 50 A.
You may select the High, Middle or Low range to match the power draw of the appliance /
device being monitored. This is important to get the most accurate readings possible.
High (H) ......................0 to 50 A
Middle (M) ..................0 to 20 A
Low (L) .......................0 to 10 A
To change the setting, pull the jumper up to detach it from the “H” pins; then push it back down
onto the “M” or “L” pins.
Install Your Current Loop
The Current Loop has a split core which opens to wrap around a single insulated conductor
running into an electrical box or to an appliance / device.
Consult with a qualified electrician before you begin.
Disconnect power to the equipment and cable before you begin.
Do not insert an exposed wire into the Current Loop.
Do not use the Current Loop in hazardous (classified) locations or life / safety applications.
Insert A Single Insulated Conductor Into Your Current Loop
1. Disconnect power to the insulated cord that you intend to monitor.
2. Open the Current Loop by either prying open the latch with a flat-tip screw driver or
pressing down on the two side tabs with your fingers to release the cover.
