Testing the Installation
Using an Unregistered 7845CZ to Test the Installation
An unregistered 7845CZ can send three types of test messages: unvalidated, validated, and
test registration. Refer to the tests below.
Unvalidated Test Message
Use this to test the path from the 7845CZ to the
cell.
SINGLE-click the tamper switch to send a test
message to the local cell.
displays how well the 7845CZ is receiving this cell.
Read the RSSI display from left to right: If the
yellow and the next two green LEDs are lit, the
display is read as "three bars." If the yellow and
the next two green LEDs are lit with the following
green LED flashing, the display is read as "three
and a half bars." This is a stronger received signal
than the previous example. See the Full-Scale RSSI
Display diagram in Figure 2.
Validated Test Message
Use this to test the path from the 7845CZ to
AlarmNet and back to the 7845CZ.
DOUBLE-click the tamper switch to send a test
message to AlarmNet with a validation request.
The yellow radio status LED blinks rapidly while
waiting for validation. Validation is a low-priority
receipt from AlarmNet to the 7845CZ and may take
several minutes to receive. If AlarmNet does not
validate a message within 90 seconds, the 7845CZ
retransmits the test message and waits for
validation.
NOTE: When a good test message is sent from the 7845CZ, it can be assumed with a high
degree of certainty that it reached AlarmNet without waiting for validation. Numerous
transmission failures (indicated by the red LED blinking rapidly) indicate that the location
chosen might be preventing the 7845CZ from transmitting well; the unit should be relocated.
To cancel any test message, single-click the tamper switch.
Test Registration
Use this to test the path from the 7845CZ to AlarmNet, then to the central station, and back
to the 7845CZ. This confirms the radio's programming and routing across the AlarmNet
network without actually registering it. Use the [T] command to initiate test registration.
Refer to Section 6: Registration for a detailed description of this feature.
NOTE: Programming Options 2, 3, and 4 must be programmed to use this feature.
