Safety functions
• Permanent sensor monitoring or automatic sensor test, interval between
tests adjustable from 0.5 to 30 days
• Wire breakage monitoring of all current outputs
• Optional backup battery with backup indication on the display, allowing
Conex
®
DIA-G to work for at least one hour after power failure
• Automatic adjustment of data specific to the sensor (for example
calibration data)
• Display of the sensor exchange intervals with a plain-text message
Backup battery
All devices can be equipped with an external backup battery as an option.
The backup battery supplies the gas warning controller, including the
electrically isolated relays, but no external devices (for example signal
lamp, aeration, sprinkler system, etc.). The battery lasts for about one hour
after power supply failure.
