External sirens
These must be located out of reach of intruders and vandals, but must be easily visible for
maximum deterrence.
Checking power availability
EN50131-1 or PD6662 Grade 2 requires the backup battery to be able to power the
system for at least 12 hours. Grade 3 requires the backup battery to power the system for
at least 30 hours. In both cases, the duration must including two 15-minute periods in
alarm.
i-on Compact
For an i-on Compact, the backup battery (when fully charged) meets the requirements of
EN50131-1 or PD6662 Grade 2.
Note:
The 12Vdc output in an i-on Compact is not backed up by the battery. Therefore, a
WiFi module powered by the 12Vdc output will not operate during a mains power failure.
i-on30R+, i-on40H+, i-onG2SM and i-onG3MM
For these control units, you must make sure that:
a) The control unit's power supply will have sufficient capacity to power all connected
devices. The i-on30R+, i-on40H+, i-onG2SM have a 1.0A power supply, of which
180mA is reserved for battery charging. The i-onG3MM has a 2.0A power supply, of
which 750mA is reserved for battery charging.
b) The backup battery can provide sufficient power in the event of a mains failure.
If there is insufficient power available from the control unit or backup battery, consider the
use of remote power supplies (see pages 17 and 26).
When considering the power drawn, include the control unit's PCB and all peripherals
powered by the control unit, including any output devices (12V and 14.4V), plug-on/plug-by
communicator, bus devices and wired detectors.
Table 3 gives a summary of the current consumed by the i-on control unit PCBs and
popular peripheral devices.
