The control panel uses 12V/7.0Ah sealed lead-acid rechargeable battery as standby power.
There is a red and a black power cords with plugs in the master controller for standby
power connection. Connect the red power cord to the positive terminal of standby power
and the black power cord to the negative terminal of standby power.
Standby power is offered overload protection by fast-blow fuse F6(2A). If the fuse
opens, remove the short or overload condition, and then replace the fuse before restoring
power. Do not substitute a higher rated fuse.
The system checks automatically the state of battery. If disconnect to standby power or
voltage of standby power , the control panel will take operation of low-voltage, "Lowvoltage"
indicator on keypad will be on, and buzzer will chirp twice in every two minutesuntil chirps 15 times(30minutes).
Under AC powered, the panel will self-check the back-up battery once in every 15 minutes, and check all the
time under AC power disconnected situation.

voltage
