7 Operation
The product monitors double-walled tanks. If a leak occurs, the vacuum in the
interstitial space drops and the product generates an alarm. The operation of
the product is therefore limited to its regular monitoring:
• The green LED is on.
• The red LED is off.
• The audible alarm is off.
7.1 Alarm condition
In the case of a leak alarm, the red LED is permanently illuminated and the
audible alarm is activated. The relay is energised.
7.2 Acknowledging an alarm
1. Press the Acknowledge button to mute the audible alarm.
- The red LED remains lit.
2. Immediately notify the installation company.
3. Remove the cause and perform a complete function test (see chapter
"Function test").
Power outage
No alarm is triggered in case of a power outage. When mains voltage is
restored, the product immediately resumes operation. If, during the power
outage, leakage has occurred, the product triggers an alarm once power is
available again.
