2 modems (PSTN or GSM) may be installed on the controller board to increase functionality. The picture below shows the 2 slots available for each modem, the primary (left) slot and the back-up (right) slot.
If both modem slots are available, always install the plug-in module in the primary slot; the system always attempts to make PSTN or GSM calls on a modem installed on the primary slot before attempting to use the back-up slot.
| WARNING: Modems are not plug and play. You must log on to the panel as Full Engineer, then power the controller board down before installing, removing or moving modems from one position to the other. After completing the modem task, reconnect the system to the power supply and log on to the controller as Full Engineer again. Configure and save the configuration. Failure to follow this process results in a CRC error. |
