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 outside the range of 10% - 85% at 30°C (86°F) noncondensing. See also the mounting recommendations below for additional environmental specifications.

Mounting the SK-5208

The SK-5208 cabinet dimensions are:

16" W x 26.4" H x 4" D (40.64cm W x 67.06cm H x 10.16cm D)

The SK-5208 panel should be located within a secured area, where it is accessible to main drop wiring runs and where it can be easily tested and serviced. End-users responsible for maintaining the panel should be able to hear alarms and troubles. When selecting a location, keep in mind that the panel itself is the main source of alarm and trouble annunciation.

When mounting on interior walls, use appropriate screw anchors in plaster. When mounting on concrete, especially when moisture is expected, attach a piece of 3/4 inch plywood to the concrete surface and then attach the SK-5208 to the plywood. Also mount any other desired components to the plywood.

DO NOT flush-mount the SK-5208 cabinet in a wall designated as a fire break.
