When AC power is present, the VISTA-128BP/VISTA-
250BP runs a brief battery test every 60 seconds to
determine if there is a battery connected, and runs an
extended battery test every 4 hours to check on the
The VISTA-128BP/VISTA-250BP may be programmed
to automatically transmit test reports to a central
station at intervals ranging from once per hour to once
per 9999 hours (field ✳27).
Burglary Walk-Test (Code +  TEST)
This test causes the system to sound keypad beeps in
response to faults on zones for the purpose of allowing
proper zone operation to be checked without triggering
alarms. This test can be activated by any-level user by
entering the corresponding security code and pressing
TEST while the burglary portion of the system is
disarmed. UL requires that this test be conducted on a
When this test is first entered, the system activates the
alarm output for 3 seconds. The system sends a Start of
Walk-Test message to the central station. The keypad
displays "Burg Walk Test in Progress" and sounds a
single beep every 15 seconds while the test remains
Open and close each protected door and window in turn.
Each action should produce 3 beeps from the keypad.
Walk in front of any motion detectors. Listen for three
beeps when the detector senses movement.
Armed Burglary System Test
Alarm messages are sent to the central station
during the armed system tests. Notify the
central station that a test will be in progress.

Testing the System
If the VISTA-128BP/VISTA-250BP finds that the battery
voltage is low (less than approximately 11.5V), it
initiates a keypad "SYSTEM LOBAT" display and a
rapid keypad beeping sound. It also sends a Low Battery
report to the central station (if programmed). The
keypad is cleared by entering any security code + OFF,
and a Restore report is sent to the central station if the
situation has been corrected.
UL requires the test report to be transmitted at least
once every 24 hours. The system can be programmed
to send the first report at any time of the day, or on
any day of the week (field ✳83).
The keypad displays the zone number and alpha
descriptor while a door or window remains open or while
a detector remains activated. The system automatically
issues a Zone 8 Glassbreak Detector Power Reset about
10 seconds after it finds a fault on this zone, to allow
faulted detectors to be reset.
To end this test, enter any security code and press OFF.
An End of Walk-Test message is sent to the central
The system automatically exits the Test mode
if there is no activity (no doors or windows
are opened and closed, no motion detectors
are activated, etc.) for 30 minutes on the
VISTA-128BP, 60 minutes on the VISTA-
250BP. The system beeps the keypad(s) twice
every 5 seconds during the last 5 minutes as a
warning that it is about to exit the Test mode
and return to normal operation.
A display of "COMM. FAILURE" indicates a
failure to communicate (no kissoff by the receiver
at the central station after the maximum number
of transmission attempts is tried). If this occurs,
verify that the phone line is connected, the
correct report format is programmed, etc.
