This new add-on feature allows SkyAlert to monitor your observatory main power.
When the power fails, SkyAlert will send an "unsafe alert" to any roof controller and/ or imaging application, to park your telescope and close the roof.
For proper installation, the computer running SkyAlert must be powered by a UPS unit.
The 9vdc....... Dew Htr. / Pwr. Monitor adapter for SkyAlert must be plugged into the main power, not the UPS.
The Dew Heater power supply also supplies power to an internal relay. When the power fails to this relay, it signals SkyAlert to generate an "unsafe alert" in its weather text file. This will close your roof via any ascom compliant roof controller or imaging application.
