TESTiNG THF SYSTEM
STEP 1: Connect a computer terminal or 7720P to the Transceiver as
described in the "PROGRAMMING' section. Power up the Transceiver. After
about 8 seconds, the unit will automatically enter Normal mode.
STEP 2 Observe the red and yellow LEDs on the Interface board.
Upon
initial power up, the 7920SE transmits five consecutive poll timeout messages
(displayed as 551555556). The red LED will flash as these messages are
transmitted, and the yellow LED will tight steady (message waiting).
The
network Master Stations recognize these messages from newly installed
transceivers and adjust their polling responsibilities accordingly. For Private
System users, these messages are used during the Master Station "AUTO
LEARN- process (refer to the No. 7610 Master Station manual for "Auto
learn" information). The yellow LED should extinguish after a brief period of
time indicating that the network Master Stations have acknowledged the new
Transceiver. Note that the po// timeout messages are used by the network
only, and are not transmitted to the Central Station monitoring receiver.
STEP 3 in a shorl time aftairthe yellow LED is extinguished, various network
messages should appear on the computer terminal screen, indicating that the
unit is receiving network radio signals. Refer to the Advanced Diagnostics
section for the specific messages that should be observed.
STEP 4: Check the radio communication path to the Central Station by
pressing T
on the terminal keyboard. This forces the 7920SE to transmit a
test message, which should be received and displayed at the Central
Station's No. 665 Digital Receiver.
For Private Systems, the message is
555555559.
For AfarmNet users, the "Field Triggered Network Diagnostic
Message" (refer to the AlarmNet manual) is transmitted. All AlarmNet users
must confirm with TAC, 600-222-6525.
STEP 5 Using the zone test lead connected to TB1-5, touch each of the six
channel input terminals. The red LED should flash as the unit transmits each
alarm,
and the Central
Station's
No. 685
Receiver should display
alarrn/restore messages for each channel.
STEP 6 Create a system test as described in the control/communicator
installation instructions. Choose a system test which is not selected as a
disabled report. The 7920SE system will mimic the control/communicator
telco tranarnied data, within the _timits described in this manual.
TO THE INSTALLER
Regufsr maintenance and inspection (at least annually) by the installer and
frequent testing by the user are vital to continuous satisfactory operation of
any alarm system.
The installer should assume the responsibilityof developing and offering a
regular maintenance program to the user as well as acquainting the user with
the proper operation and timitations of the alarm system and its component
parts. Recommendations must be included for a specific program of frequent
testing (at least weekfy) to insure the system's proper operation at all times.
