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.
A Test 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.

To verify proper zone coverage with an Test Tag, use the following
instructions:
1. Using an S-TAD, activate the Test Tag.
NOTE: Once activated the Test Tag’s LED will change state when it is
in a Tx Activation Field. Therefore, to verify the Test Tag is active,
turn on the TAD and place the Test Tag near it. The Test Tag’s LED
will change state since an S-TAD has a small TX Activation Field
associated with it.
2. With the Test Tag in your hand, slowly approach each zone at various
angles and orientations. The Test Tag’s LED will change state when it
detects the zone’s TX Activation Field.
