Emerson EASYHEAT MSA-1 Installation & Operation Instructions

MSA-1
GENERAL
The MSA‑1 sensor detects falling or blowing snow coming
in contact with the sensor grid, then sends a signal to the
MSC‑1 to energize heating equipment (snow melting or de‑
icing cables, etc.).
The sensor operates on low voltage supplied by the MSC‑1
control unit and has a built in 1/2" NPT conduit connection
and includes 10´ of wire for connection back to the MSC‑1.
The MSA‑1 is well suited for mast mounting and custom
positioning. Rounded features and neutral colour allows
the sensor to discreetly blend into almost any environment.
The MSA‑1 connection wire may be extended up to 500´
with an appropriately rated 18‑20 AWG 3 wire unshielded
stranded cable.
The main components of them MSA‑1 are shown in Fig.1.
