Control Panel Installation
3.1 Electrical Specifications
3.2 Environmental Specifications
It is important to protect the SK-5208 control panel from water. To prevent water damage, the following
conditions should be AVOIDED when mounting the units:
• Do not mount directly on exterior walls, especially masonry walls (condensation).
• Do not mount directly on exterior walls below grade (condensation).
• Protect from plumbing leaks.
• Protect from splash caused by sprinkler system inspection ports.
• Do not mount in areas with humidity-generating equipment (such as dryers, production machinery).
When selecting a location to mount the SK-5208 control panel, the unit should be mounted where it will NOT be
exposed to temperatures outside the range of 0°C-49°C (32°F-120°F) or humidity equal to or greater than 93% at
30°C (89°F) noncondensing.
See also the mounting recommendations in Section 3.5 for additional environmental specifications.
3.3 Wiring Specifications
To avoid induced noise (transfer of electrical energy from one wire to another), keep input wiring isolated from
high current output and power wiring. Induced noise can interfere with telephone communication or even cause
