4.3 Wireless considerations
Power-up sequence
The Wireless Gateway should be installed and functioning properly before
any wireless devices are powered. Battery is already installed in the Location
Anchor. Move power switch to "ON" position to power up. This results in a
simpler and faster network configuration. Enabling Active Advertising on the
Gateway ensures new devices are able to join the network faster. For more
information, see the Wireless Gateway Reference Manual.
Antenna position
The antenna is internal to the Location Anchor. To achieve optimal range
and performance, position the Location Anchor with the stem in a horizontal
position as shown in
Figure 4-1 . Good connectivity can also be achieved in
other orientations. The antenna should also be approximately 1 m (3 ft.)
from any large structure, building, or conductive surface, and a minimum of
2 m (6 ft.) and maximum of 4 m (13 ft.) from the ground to allow for clear
communication to other devices. Refer to best practices for additional
information on optimal mounting locations of the Location Anchor.
4.4 Electrical
Battery
The Emerson Location Anchor is self-powered. The battery is a single “D”
size primary lithium/thionyl chloride battery. Each battery contains
approximately 5.0 grams of lithium. Under normal conditions, the battery
materials are self-contained and are not reactive as long as the battery is
maintained. Care should be taken to prevent thermal, electrical, or
mechanical damage. Contacts should be protected to prevent premature
discharge. Battery cannot be changed in a hazardous location.
4.5 Installation considerations
Procedure
1. Inspect mounting bands periodically and re-tighten if necessary.
Some loosening may occur after initial installation due to thermal
expansion/contraction.
2. The stainless steel mounting bands could be affected by stress
corrosion and potentially fail when in the presence of chlorides.
3. The Location Anchor should be installed such that steam or other
high temperature fluids do not directly impinge the housing of the
Location Anchor.
