General Information
To help ensure that a user has access in the rare event of a problem, the VistaKey contains a
Reduced Capability Mode (RCM), which allows the system to operate on the card database
stored in the VistaKey. The VistaKey automatically enters RCM in the event communication
between the VistaKey and the alarm panel is lost for a period of two or more minutes
(providing that the VistaKey has power applied). The RCM mode automatically ends within
one minute after communications are restored.
Additionally, when you have a direct-wire computer connection and you request a download
to the alarm panel using the downloader, system-wide RCM will occur 2 minutes after the
direct-wire computer connection is established, and remains until 1 minute after the
connection is terminated. While in the Reduced Capability Mode, the VistaKey recognizes
and grants access for all cards authorized to enter through an access point (without regard to
time schedules).
The card database is downloaded from the alarm panel to the VistaKey within ten minutes of
leaving #79 mode, an alarm panel download, VistaKey module powerup, or reaching 12 midnight.
Therefore, if the system should enter RCM while you are working on the card database, it is
possible that your recent changes may not have been downloaded and the VistaKey is operating
on the card database as it existed before you started working on it.
RCM Description
When the VistaKey has entered RCM, the alarm panel keypad displays the zones controlled
by the VistaKey as being in "Check," and the system grants access at the access point being
controlled by the VistaKey. While operating in RCM, the VistaKey has the following
capabilities and limitations:
• On entering RCM, the door/access point is put into the protect/normal mode regardless of
the state it was in previously (e.g., locked, bypassed, or exit only).
• While in RCM, the VistaKey cannot grant a card access based on executive privilege that it
would normally inherit from its access group assignment; however, it will do this based on
executive privilege assigned to the card itself.
• While in RCM, access restrictions based on time schedules, access group armed partition
restriction, and access group disables are waived.
• While in RCM, the VistaKey can perform an access point grant, protect, or bypass card
action based on the information in the card database. Hence, you can create cards that will
provide an access point grant, protect, or bypass while the VistaKey is in RCM.
• If a card disarms an alarm panel partition during normal operation, it will not disarm the
partition while operating in RCM.
