Introduction
Each sensor has an associated flag that is set if any alarm on the sensor is active. This can be used to vary the logging rate
for the sensor. For example, taking more frequent logs when water level is high compared to a less frequent “routine” log
in normal conditions.
The iRIS also maintains a global “alarms active” flag that is set if any alarm on any sensor in the device is active. This is
used to trigger a call-in or data transfer to the designated host. As well as the call-in, this flag can also control the digital
outputs.

Real Time Clock & Calendar
The iRIS has a non-volatile real time clock that can be read and/or synchronised using HydroTel™ or iLink 3.
1.2.7
Security
The iRIS can be configured with a PIN code to prevent unauthorised access to restricted information through the LCD and
keypad. This is especially useful when the iRIS is installed in a location where it is accessible to the general public.
