100 Concord 4 Installation Manual
Cellular backup communication
To check the cellular communication between the panel and the central monitoring
station:
1. Contact the central monitoring station to inform them that you are testing the
system.
2. Install and activate the SuperBus 2000 cellular backup module.
3. Verify or change the following CS phone panel option settings shown in “Cellular
backup communication” above.
Note: If the current settings do not match the test settings, record the current
settings (Table 17 on page 97), so that they can be restored when this test is
complete.
4. Disconnect the phone line by unplugging the DB-8 cord from the RL 31X jack.
5. Initiate a phone test (8, system master code, 2).
6. The phone test attempt should fail via the phone line within 5 minutes. The panel
will emit a long low tone (and speak “phone failure 1” if so equipped).
7. Wait for the phone test to succeed via the cell backup. The panel should emit a
short high tone (and speak “phone test okay” if so equipped).
8. Verify the CS report.
9. If success does not occur, verify that the signal strength (RSSI) shown on the
cellular backup module is acceptable and repeat the process.
