Aiphone LE-SS-1G User Manual

Vandal and Weather Resistant 1-Gang Sub Station

- INSTRUCTIONS -

The LE-SS-1G is a 1-gang stainless steel vandal proof and weather resistant sub station designed for use with the LEM, LEF, LAF/LDF-C, AP-M, and MP-S systems. This unit is constructed with 12 gauge stainless steel and can be flush mounted into a 1-gang box, or surface mounted with the SBX-1G. Each unit includes tamper proof screws and a tool for installation.

INSTALLATION:

1. For flush mounting, install sub station in standard 1-gang electrical box with min. 2-1/2" depth.

2. For surface mounting, install sub station in the SBX-1G surface mount enclosure.

3. IMPORTANT! This unit is designed for use in normal weather conditions, and is made to allow for drainage and evaporation of moisture that naturally gets into it. 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. Warranty does not cover damage caused by sealing the unit.
