 Verifying Proper Zone Coverage
 Identifying Foreign Tag-Activating Sources
DISCLAIMER: Due to each facility’s unique environment, an LED Tag cannot give an exact measurement of zone
coverage; it can only give an estimation of zone coverage.
Verifying Proper Zone Coverage
An LED Tag (Figure 3.8) is used to verify proper zone coverage during
installation, adjustment, or testing of a monitored zone.
Proper zone coverage fully protects the intended area (door, elevator,
hallway, or any other passageway) without extending into other areas (in
front, in back, on sides, above, and beneath the intended area).
Monitored zones emit a Tag-activating signal called the Tx Activation Field.
When a Tag enters a zone’s Tx Activation Field, the system will detect the
Tag and take appropriate action response.
An LED Tag can detect a zone’s Tx Activation Field without causing alarms
making it a quick and easy way to verify proper zone coverage. This is not
only useful in ensuring complete zone coverage but also in locating areas
where a Tx Activation Field may be extending into common areas and
causing nuisance alarms.
Figure 6.8 The LED Tag
To verify proper zone coverage 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 approach each zone at
various angles and orientations. The LED Tag’s LED will illuminate
when it detects the zone’s Tx Activation Field.
