communicator fitted the requirement drops
to 30 hours.
This means that all the devices powered by
the backup battery, including the control
unit and at least one keypad, should
together draw no more in total than an
average of 570mA over a 30 hour standby
time. Note that for Security Grade 3 the
control unit must use a plug-by
communicator, which may have its own
power supply.
For Security Grade 2 the required battery
standby time is 12 hours. However, the
total average current available over 12
hours from the 17Ah battery is limited by
the power supply to 750mA. (The current is
limited to 750mA because when mains is
present the 1.5A power supply reserves
750mA to recharge batteries, leaving
750mA available to supply the system.)
The table below shows the current
consumption of the control unit and each
device that can be fitted to it.
