MSA‑1 Installations & Operation Instructions
INSTALLATION INSTRUCTIONS
1. Mount the MSA‑1 securely in upright position in an open space, in direct contact with snowfall pattern with a ½" NPT
mounting connector. The unit is water‑resistant, but it is not designed to be submerged or immersed in water. Ensure that
the mounting location is close (less than 10 feet) to the MSC‑1 Control Panel or a suitable connection box. See Fig.2
2. Ensure that all pipe connections are sealed to prevent any penetration of water inside of conduit or
electrical junction box.
3. The MSA‑1 connection wire may be extended up to 500' with an appropriately rated 18‑20AWG 3 wire unshielded cable.
Ensure that all electrical connections within connection boxes are sealed to prevent any penetration of water.
4. The MSA‑1 is wired directly to the appropriate zone sensor terminal block on the MSC‑1 control panel.
