ERT-A2 ALERT2 Configuration Manual Revision 1.0 Warning: The solar input is suitable for solar panels rated as 12V nominal only. 24V solar panel can produce open circuit voltages of 44Vdc which will exceed the rated input of the solar regulator and cause damage. -
Page 23: System Design
ERT-A2 ALERT2 Configuration Manual Revision 1.0 System Design Unit type overview The ERT-A2 unit can be configured through the menu to support three different unit types: Field Station: Very low power consumption unit which is in a sleep mode most of the time monitoring its sensor inputs and wakes to send data frames when events occur or on periodic update messages. -
Page 24: Repeater Station
ERT-A2 ALERT2 Configuration Manual Revision 1.0 Field Station units will operate at the lowest current consumption modes and therefore in rain only applications can operate from internal battery for more than 2 years without replacement. Field stations can be optioned with either VHF or UHF radio, 25W VHF radio, Cellular or Satellite communications options. -

Page 26: Repeater Station - Multi-Frequency Or A1 Migration
ERT-A2 ALERT2 Configuration Manual Revision 1.0 Antenna systems would usually be installed separately, but if there is limited space on the mast structure then a duplexer can be used to run a single antenna. Using a duplexer typically would require a minimum frequency separation of around 4MHz. When using two antennas in the installation, to maximize the performance care should be taken to ensure there is adequate antenna separation. - Page 27 ERT-A2 ALERT2 Configuration Manual Revision 1.0 Linked Repeater to second receive frequency network data. Allows merging of two or more frequencies into one stream in complex networks. Repeater will aggregate data frames in periods of high message density. Can also be used to create a High Capacity Repeater configuration for network backbone applications.
