Access Control Using VistaKey
The VistaKey is a single-door access control module
that, when connected to the VISTA-128BP/VISTA-
250BP, provides access control to the protected
premises. The alarm system can support up to 15
VistaKey modules (15 access points).
DO NOT USE BOTH
the VistaKey and a
PassPoint Access Control System on the same
alarm panel.
U
L
The VistaKey module contains three zones.
These zones should ONLY be used for access
control functions in UL installations. THESE
INPUT ZONES ARE NOT TO BE USED FOR
FIRE AND BURGLARY APPLICATIONS IN UL
INSTALLATIONS.
VistaKey Features
•
Each VistaKey communicates with the VISTA-
128BP/VISTA-250BP via the V-Plex polling loop.
•
In the event local power to the VistaKey is lost, the
VistaKey module provides backup 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 500 cardholders.
•
The addition and removal of VistaKey modules
from the system is easily accomplished via the
VISTA-128BP/VISTA-250BP keypad.
•
All configurable options for each VistaKey are
accomplished via software, firmware, and
nonvolatile memory, eliminating the need for PC
board jumpers. The access point zone number (1-
15) is set via a user-friendly, 16-position rotary
switch.
•
Each VistaKey provides one open-collector output
trigger (sink 12mA @ 12VDC).
Mounting and Wiring the VistaKey
For detailed instructions on how to install and

and card reader.
2 Mount the door status monitor (DSM) and/or
request-to-exit (RTE) devices.
3 Using
Figure 3-31
as a reference, connect the
card reader interface cable to TB3,
making the
+5V or +12V connection last
.
4 Connect the leads to TB1 in the following
order:
a. All ground leads to terminals 2, 5, and 9.
b. The DSM, (optional) 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).
5 Connect the (–) polling loop and (+) polling
loop leads (from the VISTA-128BP/VISTA-
250BP) to terminals 4 and 3, respectively.
6 Set the Address Select switch to the desired
access door number (1-15).
