APPENDIX A. THE VISONIC LTD. POWERCODE
SYSTEM
A-1. The PowerCode Message
Format
The PowerCode message transmitted by the DISCOVERY
QUAD MCW includes the 24-bit ID and a status report (see Fig.
A1).
Figure A1. Transmitted Data
A message includes the following data:
• Detector's ID: Any message transmitted starts with the 24-
bit ID assigned to the particular detector unit.
• Tamper / Restore: Upon removal of the unit's front cover, a
message will be transmitted with a "tamper marker" ON. If
the unit's cover is put back, a message will be transmitted
with the tamper marker OFF ("Tamper Restore").
• Alarm: Once the detector is in alarm, a message will be
transmitted with an "alarm marker" ON.
• Low Battery: A special battery condition marker is used to
report the battery status in any message. The battery is
tested once an hour and if found low, the "low battery
marker" is set to ON in all following messages.
• Supervision Message: A special "supervision message
marker", when set to ON, identifies the periodic supervision
messages transmitted automatically at 1 hour or 15 minute
intervals. This marker will be OFF in all other messages.
• Transmitter Type: A special marker indicates the type of
the transmitter:
n Supervised or non-supervised
n Reports or does not report restorals after alarm
The DISCOVERY QUAD MCW does not report restorals after
alarms.
• Checksum: Checksum bits at the end of the message allow
the receiver to determine whether an incoming message is
valid (error-free). This feature considerably enhances the
reliability of the wireless communication link.
A-2. Anti-Collision
To overcome message collisions at the receiving end,
PowerCode transmitters transmit 3 data bursts at random
intervals, with 6 repetitions of the same message in each burst
(Fig. A2). This redundancy improves the probability of
reception.
Note: Periodic supervision messages are an exception to this
rule - they consist of a single 6-message burst.

WARRANTY
Visonic Ltd. and/or its subsidiaries and its affiliates ("the Manufacturer") warrants its
products hereinafter referred to as "the Product" or "Products" to be in conformance
with its own plans and specifications and to be free of defects in materials and
workmanship under normal use and service for a period of twelve months from the
date of shipment by the Manufacturer. The Manufacturer's obligations shall be
limited within the warranty period, at its option, to repair or replace the product or
any part thereof. The Manufacturer shall not be responsible for dismantling and/or
reinstallation charges. To exercise the warranty the product must be returned to the
Manufacturer freight prepaid and insured.
This warranty does not apply in the following cases: improper installation, misuse,
failure to follow installation and operating instructions, alteration, abuse, accident or
tampering, and repair by anyone other than the Manufacturer.
This warranty is exclusive and expressly in lieu of all other warranties, obligations or
liabilities, whether written, oral, express or implied, including any warranty of
merchantability or fitness for a particular purpose, or otherwise. In no case shall the
Manufacturer be liable to anyone for any consequential or incidental damages for
breach of this warranty or any other warranties whatsoever, as aforesaid.
This warranty shall not be modified, varied or extended, and the Manufacturer does
not authorize any person to act on its behalf in the modification, variation or
extension of this warranty. This warranty shall apply to the Product only. All
products, accessories or attachments of others used in conjunction with the Product,
including batteries, shall be covered solely by their own warranty, if any. The
Manufacturer shall not be liable for any damage or loss whatsoever, whether directly,
indirectly, incidentally, consequentially or otherwise, caused by the malfunction of
the Product due to products, accessories, or attachments of others, including
batteries, used in conjunction with the Products.
The Manufacturer does not represent that its Product may not be compromised and/or
circumvented, or that the Product will prevent any death, personal and/or bodily
injury and/or damage to property resulting from burglary, robbery, fire or otherwise, or
that the Product will in all cases provide adequate warning or protection. User
understands that a properly installed and maintained alarm may only reduce the risk
of events such as burglary, robbery, and fire without warning, but it is not insurance
or a guarantee that such will not occur or that there will be no death, personal
damage and/or damage to property as a result.
The Manufacturer shall have no liability for any death, personal and/or bodily
injury and/or damage to property or other loss whether direct, indirect, incidental,
consequential or otherwise, based on a claim that the Product failed to function.
However, if the Manufacturer is held liable, whether directly or indirectly, for any loss
or damage arising under this limited warranty or otherwise, regardless of cause or
origin, the Manufacturer's maximum liability shall not in any case exceed the
purchase price of the Product, which shall be fixed as liquidated damages and not
as a penalty, and shall be the complete and exclusive remedy against the
Manufacturer.
Warning: The user should follow the installation and operation instructions and
among other things test the Product and the whole system at least once a week. For
various reasons, including, but not limited to, changes in environmental conditions,
electric or electronic disruptions and tampering, the Product may not perform as
expected. The user is advised to take all necessary precautions for his/her safety
and the protection of his/her property.
