Identifying Foreign Tag-Activating
Sources
In addition to verifying proper zone
coverage, an LED Tag (Figure 3.5) can be
used to identify foreign Tag-activating
sources to help preserve your Tags’ battery
life and prevent nuisance alarms.
Monitored zones emit a Tag-activating
signal called the Tx Activation Field. When
a Tag enters a zone’s Tx Activation Field, it
is activated. The system detects the activated
Tag and takes appropriate action response.
However, there are sources that can activate
a Tag other than a Tx Activation Field.
When Tags are activated by these “foreign”
sources, battery life is depleted and/or
nuisance alarms can be caused. Therefore,
identifying these sources will prolong Tags
battery life and prevent nuisance alarms.
To identify activating sources with an LED
Tag, use the following instructions:
1. Using a TAD, activate the LED Tag.
NOTE:
The Signal Strength LEDs
of the TAD will not indicate the
state of the LED Tag. Once
activated the LED Tag’s LED will
illuminate when it is in a Tx
Activation Field. Therefore, to
verify the LED Tag is active, turn
on the TAD and place the LED Tag
near it. The LED Tag’s LED should
illuminate (since a TAD has a small
Tx Activation Field associated with
it).
2. With the LED Tag in your hand,
slowly investigate each area for
possible activating sources*. The
LED Tag’s LED will illuminate
when it detects an activating source.
3. Note each activating source and
keep Tags away from those sources.
4. When finished, deactivate the LED
Tag using a TAD.
*Some activating sources can be:
Computer Monitors
Unshielded computer cables
Television Sets
Medical Monitoring equipment
X-ray and other imaging equipment
Fluorescent Lighting
Wireless Communication Devices
