Mute Function - HumanTechnik lisa Bedienungsanleitung

Contamination forecast
The smoke detector calculates from the actual level of contaminati-
on how long it can reliably continue to operate at the same level of
contamination.
Active service forecast
During the function test, a contamination forecast is created auto-
matically. If the forecast is greater than 15 months the test is positi-
vely confirmed.

Mute function

In case of an alarm, the audible alarm of the smoke detector can be
muted for 10 minutes by pressing the test button or by removing the
device from the base for a short period. As soon as the detector no
longer detects smoke, it returns to normal operation.
Delayed deactivation
Automatic, delayed deactivation after removal of the smoke detector
from the base (5 minutes) so that there is sufficient time to test the
smoke detector outside the base.
