1. System operation and technical details
1.1
The module’s short description
The Pager 7 is a versatile 3G-based communicator module, that can be used to perform small
automation tasks, surveillance tasks (with camera management) and it can also be used as a
stand-
alone security system. The product’s speciality is the multiplatform application for
programming the Pager 7 device remotely through the internet or via USB.
1.2 Automatic power disconnection function
The Pager 7 is provided with built-in automatic power disconnection function. If the supply
voltage drops below 8.3V, the module turns off automatically and it turns back on when the
supply voltage is at least 11.6V.
Attention!
The minimum supply voltage level required to turn the module on is 11.6V!
After turned on with supply voltage higher than 11.6V, the module can operate stably
even at lower supply voltage, but not lower than 8.3V.
If the module is powered from a power supply provided with a backup battery and there is no
other electrical load on the battery when charging fails (e.g. in case of a power cut), while the
battery discharges, the module turns off automatically at 8.3V voltage level.
Thereafter, if the battery is in good condition, it can regenerate and can reach the terminal
voltage of 11.6V where the module turns back on, then the battery may discharge again below
8.3V. This may result a continuous switching on and off cycle that lasts until the battery can no
longer regenerate to the 11.6V voltage level. If this phenomenon occurs, the battery is flat and it
should be replaced.
1.3 Data traffic
The estimated traffic on the SIM card inserted into the Pager 7 module is expected to be
approximate ~20 MB per month by minimum usage. The data traffic rate depends on the
frequency of use, the stability of the cellular network and the services used.
Data traffic generating services:
● Remote programming/controlling
● Reporting to a monitoring station
● Downloading event log and configuration remotely
● Firmware upgrade
● Notification sending (e-mail, voice call, SMS)
● Report sending
