2.0 General Installation
2.1 Installation Considerations
• wLSN devices are intended only for indoor, dry applications.
• Mount wLSN devices on flat, rigid surfaces. Some devices can
be optionally corner mounted as indicated in the installation
instructions.
• Avoid mounting wLSN devices in areas with large metallic
objects, electrical panels (for example: control panel or fuse
box) or electric motors. They might reduce the radio-frequency
(RF) range of a wLSN device.
• Avoid installing the devices where excessive humidity or
moisture, or temperatures outside of the acceptable operating
range exist.
• Wire all devices according to their specifications.
• wLSN devices use batteries of varying types. When installing
batteries, observe safety and polarity recommendations as
indicated in the documentation for those products. Refer also
to Section 2.6 Battery Requirements on page 19.
