Air Flow Sensors (RMA-AF1-SEN & RMA-AF2-SEN)

Step 2: Connect your Air Flow 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 Air Flow Sensor comes with a 25' speaker cable. Follow

these steps to attach one end of the speaker cable to the Air Flow

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. Twist the speaker cable leads with ½" exposed wire to the Air Flow

Sensor's leads. (You may also need to strip the Air Flow sensor's

leads a bit more to have enough to twist, as they arrive with about

1/4" exposed wire.) The Air Flow Sensor's leads are non-polarized, so

you may connect either side of the speaker cable to either side of the

sensor leads.

4. Cap or tape the connected leads to avoid a short.

5. 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.

6. 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.
