Vandal and Weather Resistant Sub Stations
- INSTRUCTIONS -
The NE-SS/A and NE-SSR are 2-gang vandal proof and weather resistant sub stations designed for use with the NEM,
NDR and NDRM systems. They are constructed of 12 gauge stainless steel and are equipped with an option for an
external output contact closure when the sub station places a call (relay required). The units either flush mount into a 2-
gang box, or surface mount with the SBX-2G. Each unit includes tamper proof screws and a tool for installation. The
NE-SSR features a red mushroom call button.
INSTALLATION:
1. For flush mounting, install sub station in standard 2-gang electrical box with min. 2-1/2" depth.
2. For surface mounting, install sub station in the SBX-2G surface mount enclosure.
3. IMPORTANT! These units are designed for use in normal weather conditions, and to allow drainage and
evaporation of moisture that naturally gets into the unit. Do not apply caulking or silicone sealant around the
unit when installing, and do not use weather stripping around the perimeter of the box when mounting. If
sealing the unit is required, the bottom must remain unsealed. Sealing the unit will prevent or inhibit moisture from
dissipating from inside the unit, which may cause corrosion or deterioration to the internal components over time.
