Tank Level Sensors (RMA-FTL1-SEN & RMA-FTL2-SEN, RMA-WTL1-SEN & RMA-WTL2-SEN)
Step 2: Connect your Tank Level Sensor to Room Alert.
Do not connect the switch sensor inputs (dry contacts) on AVTECH products to any live
circuit.
Use only low-voltage 2-wire cable to connect switch sensor inputs.
Your Tank Level Sensor comes with a 25' speaker cable. Follow
these steps to attach one end of the speaker cable to the Tank
Level Sensor’s leads, which are non-polarized, and the other end
to a switch port on your Room Alert:
1. Separate and strip the leads on one end of the included
speaker cable, exposing about ¼" of wire.
2. Separate and strip the leads on the other end of the included speaker cable, exposing
about 1/2" of wire.
3.
Strip the leads on the Tank Level Sensor cable, exposing about 1/2" of wire.
4.
Twist the speaker cable leads with ½" exposed wire to the Tank Level
Sensor leads. The sensor’s leads are non-polarized, so you may
connect either side of the speaker cable to either side of the Tank
Level Sensor cable.
5. Cap or tape the connected leads to avoid a short.
6. Run the speaker cable back to your Room Alert. Try to avoid running it near large
electromagnetic devices or fluorescent lights, which produce EMI and can interfere with
sensor readings.
7.
Connect the free ends (the 1/4" leads) of the speaker cable to an
open switch port on your Room Alert. Be sure the bare wire, not the
insulation, connects to the port. Again, the leads are non-polarized, so
you may connect either lead to either side of the open port.
