SPD-2000 NS

Supervised RFID Spatial Position Detector

INTRODUCTION

The SPD-2000 NS is a fully supervised RFID spatial position detector
from Visonic Technologies (VT). The SPD-2000 NS is ideal for
protecting fine art in public instutions, museums, galleries or private
residences.

The SPD-2000 NS detector is designed to descretly and covertly
protect, location monitor and identify all types of fine art assets
including paintings, statues, antiques and ceramics in environments
where conventional security systems are not quite adequate.

The SPD-2000 NS is also suitable for high-risk, stationary general
asset protection; including but not limited to computers, general office
and medical equipment. When deployed as part of a 'SpiderAlert'
system, the SPD-2000 NS can provide on-going around-the-clock
asset location monitoring in near-real time (30 second intervals).

Each SPD-2000 NS detector is deployed with its own 24-bit
identification code (factory set) so that each asset is protected by a
uniquely numbered tag.

The SPD-2000 NS contains an ultra-sensitive acceleration sensor
(silicone chip mounted) that measures on two axes static (vibration)
as well as dynamic (gravity) accelerations. Thus when a protected
asset is moved without authorization, the SPD-2000 NS transmits a
real-time identifiable coded alarm message every 30 seconds while in
motion to the 'SpiderAlert' system. Each alarm transmission consists
of three messages (each message @ 300ms in duration), at 700ms
intervals. Thus the total duration of an alarm transmission is
approximately 2300ms.

The SPD-2000 NS automatically transmits an alarm restore message
when the asset is again at rest or after 10 minutes has elapsed
without detecting further acceleration changes so that the system can
handle new alarm conditions. The SPD-2000 NS returns to
generating a single supervision transmission at @ 15min. intervals for
a maximum of 5 messages/hr. Each supervison transmission consists
of a single message (@ 300ms in duration). Accordingly, total
duration of supervision transmissions /hr is @ 1500ms.

To ensure high operational reliability in security sensitive
environments, the SPD-2000 NS automatically transmits supervisory
status messages at 15 minute intervals or 60 minute intervals
depending on the enabled mode selection position of Function Switch
2 (as detailed table 1) to the 'SpiderAlert' system throughout the day.

Installation Instructions

The SPD-2000 NS is also tamper protected. Upon removing the unit's
cover, the detector automatically transmits a Tamper alarm in near­real time (30 second intervals) as an alarm tracking transmission.
Should the SPD-2000 NS not detect further acceleration changes
after 10 minutes has elapsed, the detector returns to generating a
single transmission @ every 15 minutes, comprised of three alarm
messages the same as described above.

The SPD-2000 NS employs a
"Smart" anti-collision transmission
methodogy to overcome message
collisions from other RFID
detectors in the protected area.

Operating power is provided by single onboard commercially
available 3.0 V 1/2 AA Lithium battery. When battery voltage is low, a
“Low Battery” marker is added to the transmitted message.

A LED illuminates upon all event transmissions (except for a low
battery condition).

SPD-2000 NS Advantages:

• Quick and easy installation. The sensor attaches to
an asset using double-sided adhesive tape or via an
optional mounting bracket.

• Supports four user selectable sensitivity levels for
detecting unauthorized asset movement.

• Powered by a single, compact 3V Lithium battery,

• Small size, enables descrete, covert asset mounting.

• Optional Alarm Tracking delivers near-real time

(30 second intervals) location monitoring of the
protected asset.

Current Drain: 500 µA (STBY), 20 mA (transmission, including
LED)

Alarm Tracking: Automatic signaling at 30 second intervals
when the protected asset is in unauthorized motion

Battery Life: At least 2 years (typical operation)
Battery Supervision: Automatic Low battery condition marker

Mounting Details

Attach the SPD-2000 NS to a corner of the asset you wish to
protect using double-side adhesive tape or by means of an
optional mounting bracket. If required, you the detector can be
affixed to either the far left or far right side of the asset as
well.

Caution: Verify that the “UP” arrow is pointing upwards
(allowed deviation: up to ± 25° in the vertical and horizontal
axes).

Field Testing

Wait 10 minutes after attaching the detector to an asset so
that the detector may 'Learn' the location of the asset. Then
move the asset to verify that alarm messages are being
transmitted by the detector and that the function LED
illuminates.

Miscellaneous Operating Information

Due to the low transmitting power and the limited range of this
RFID device (as required by the FCC and other international
regulating authorities), there are a number of operational
limitations that need to be considered considered and
handled:

• Receivers may be blocked by radio signals that occur on
or near their operating frequencies.

• A receiver can only respond to one transmitted signal at a
time.

• Wireless equipment should be regularly tested to
determine current sources of interference and to protect
against faults.

Battery Safety and Disposal

Promptly remove the worn-out battery from the detector and
dispose of according to manufactuer's instructions. For more
information, contact your local government for the disposal or
recycling practices in your area.

CAUTION: To eliminate the risk of possible explosion, do not
attempt to replace the battery with a non-specified type.
