VISTA-128B Installation and Setup Guide
VistaKey Features
VistaKey features are as follows:
•
Each VistaKey communicates with the VISTA-128B via a special global polling protocol
of the V-Plex polling loop.
•
In the event local power to the VistaKey is lost, the VistaKey module provides back-up
monitoring of the Access Point door via a built-in V-Plex device that is powered solely
from the polling loop. It is programmed as a new type of V-Plex device as part of the
control's V-Plex Device Programming. A serial number label is affixed to the VistaKey
module for manual entry of its serial number.
•
The VistaKey supports up to 250 cardholders.
•
All configurable options for each VistaKey are accomplished via software, firmware, and
non-volatile memory, eliminating the need for PC board jumpers.
•
Access Point zone numbers (1-15) are assigned via a user-friendly, 16-position rotary
switch.
•
The addition and removal of VistaKey modules from the system is easily accomplished
via the VISTA-128B keypad.
•
Each VistaKey provides one open-collector output trigger (sink 12mA @ 12VDC).

b. The (optional) DSM, RTE, and General Purpose leads to terminals 6, 7, and
8, respectively.
c. Door Strike (or Mag Lock) lead to terminal 10.
d. Local +12v or +24v supply lead to terminal 1.
e. Local +12v or +24v supply lead to the N/C relay terminal 11 (if a Mag Lock is
being used), OR to the N/O relay terminal 10 (if a door strike is being used).
Connect the – polling loop and + polling loop leads (from the VISTA-128B) to
terminals 4 and 3 respectively.
Set the Address Select switch to the desired access door number (1-15).
Repeat steps 1 through 6 for each VistaKey being installed.
