Technical Specification i-on50EX/EXD
Page 38
EN50131-6 ratings
The i-on50EX/EXD provides space for one 17Ah
battery.
Under EN50131-6 for Security Grade 3
installations the required battery standby time is
60 hours. However, with an ATS4 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 i-
on50EX 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.
Fuses
The control unit has a replaceable T250mA mains
fuse.
Electrical Safety
