referred to as “Alarms.” Other alarm types are
referred to by name (i.e., Door Ajar, Loiter,
Supervisor, Band Alarm).
Egress
An alarm (i.e., an Egress alarm) occurs
whenever a Tag enters a monitored zone and the
door is opened or a PIR is tripped.
Door Ajar (Optional)
A Door Ajar alarm occurs when a door is open
for longer than the preset time (adjustable).
Loiter (Optional)
A Loiter alarm occurs when a Tag lingers in a
monitored zone for longer than the preset time
(adjustable).
Supervisor
A Supervisor alarm occurs when the TX or RX
performance of the system has been altered due
to tampering or inadvertent acts such as cut
wires, antenna damage.
Band Alarm (BR 4200 systems only)
A Band Alarm occurs when a BR42 Tag band is
loosened, cut, saturated, removed, or tampered
with.
How Accutech Systems Work
 Double-conditioning
 Door zones
 Elevator zones
 Hallway zones
This section explains how Accutech Systems
react to a Tag entering a monitored door,
elevator, or hallway as well as alarm definitions.
Double conditioning
At most zones, two conditions are required to
generate an alarm. For example, at a door zone,
a Tag must be detected in the zone and the door
opened or, in hallway zones, a Tag must be
detected in the zone and PIR detection to
generate an alarm. Double conditioning (set
during installation) helps prevent nuisance
alarms.
Door zones
When a Tag enters a monitored door zone, the
system will detect the Tag. At that moment
(provided the door is closed, has a Magnetic
Lock(s), and the Lock is unobstructed) the
Magnetic Lock will energize, locking the door.
The Lock will remain locked for as long as the
Tag is in the monitored zone. When the Tag
leaves the monitored zone, the door will unlock
after an adjustable period of time (unless it is set
to latch when an alarm occurs).
Egress
If a Tag enters a monitored door zone with or
without a Magnetic Lock(s) and the door is
already open (or is opened while the Tag is in
the zone), the Accutech System will go into
alarm.
