3.0 INSTALLATION
The HLI should not be installed until after all construction cleanup has been completed in order to avoid any
potential damage to the electronics due to dust and debris. Before installing the HLI assembly into the
enclosure, thoroughly clean the enclosure to remove any dirt, dust and debris.
3.1 MOUNTING
LOCATION
The mounting location for the HLI is very important. The HLI must be located in the same room and within 50
feet (15 m) of the host control panel. The following guidelines shall be considered when selecting the
mounting location for the HLI:
1. Locate the HLI enclosure in an area that is readily accessible with sufficient room to allow easy
installation and maintenance.
2. The room shall be capable of maintaining a nominal temperature of 32
°
- 120
°
F (0
°
- 49
°
C) with a
relative humidity of 93%.
3. Additional items to consider when selecting the mounting location shall include: vibration, dust,
moisture, electromagnetic interference, and radio frequency interference.
All of the items listed above could adversely effect the successful operation and useful life of the HLI
electronic components and should be avoided if possible.
3.2 ENCLOSURE
INSTALLATION
The HLI enclosure is equipped with four mounting holes in the back box that allows surface mounting of the
box to the wall surface (See Exhibit 5). The mounting holes are spaced at 10 inch (25.4 cm) horizontal
centers and 4 inch (10 cm) vertical centers.
The back-box is equipped with conduit knockouts on all four sides that allows easy access into the box for
electrical connections to the HLI.
