2.2. The Power Supply
The Voice Call Point can be powered by either AC power or backup battery.
AC Power
A DC 9V 1A SPS power adapter is provided for AC power connection.
- When AC power is connected, the Green LED will turn steady on to indicate AC
connection.
- When AC power is disconnected, the Green LED will flash once every 5 seconds to
indicate AC failure, the Voice Call Point will make AC fail report.
Backup Battery
In addition to the AC power adapter, a rechargeable battery is installed inside VCP-LTE
to serve as a backup in case of a power failure.
-During normal operation, the AC power adapter is used to supply power to VCP-LTE
and at the same time recharge the battery. It takes approximately 72 hours to fully
charge the battery.
-If the battery switch is set as OFF, the battery will not be charged when AC power is
connected and nor will it serve as a backup power source when AC power is missing.
You need to switch the battery to ON for it to be charged when AC power is connected
and serve as a backup power source when AC power is missing.
Low Battery Detection
The Voice Call Point can detect the battery voltage. When the battery voltage is low, the
Voice Call Point will make Low Battery report.
If the battery is extremely low, the Voice Call Point will stop all function. It will not report
upon alarm activation and will emit 4 beeps as an alert.
