VistaKey Features
•
Each VistaKey communicates with the VISTA-120
via the V-Plex polling loop.
•
In the event local power to VistaKey is lost, a
VistaKey module provides backup monitoring of
the access point door via a built-in Polling Loop
device that is powered solely from the polling loop.
It is programmed as a new type of Polling Loop
device as part of the control’s Polling Loop Device
Programming. A serial number label is affixed to
the VistaKey module for manual entry of its serial
number.
•
VistaKey supports up to 250 cardholders.
•
The addition and removal of VistaKey modules
from the system is easily accomplished via the
VISTA-120 keypad.
•
All configurable options for each VistaKey are
accomplished via software, firmware, and
nonvolatile memory, eliminating the need for PC
board jumpers, except assigning the access point
zone number (1-15), which is set via a user-friendly,
16-position rotary switch.
•
Each VistaKey provides one open-collector output
trigger (sink 12mA @ 12VDC) and one Form C
transfer contact relay.
