The following major system alarms are defined:
Install Arm State: The Install Arm State alarm is displayed. This alarm warns when a
wireless unit is in installation mode. After installation the wireless unit should be disarmed.
This will increase the wireless link’s data-carrying capacity and stop the installation tone
generator. The wireless link is disarmed from the ‘Installation Wizard’ see section 8.3.5.
