Function test for water detector QFP910
Check the function of the water detector once a year. To do this, immerse
both water detector contacts in water.
A corresponding action is triggered depending on the central apartment unit's
configuration; e.g.:
– The safety shutoff valve of the main line is closed => no more water in the
entire building.
– The buzzer of the central apartment unit is activated.
The pending alarm must be acknowledged on the central apartment unit to al-
low the safety shutoff valve to reopen, the buzzer to turn off and the alarm to
be resolved:
Main menu > Faults > Acknowledge faults:
The alarm cannot be acknowledged for as long as the water detector
is immersed in water, or the alarm is reactivated immediately.
Calibrate DELTA reflex smoke detector
We recommend that you press the test button monthly on the smoke detector
to avoid false alarms. This calibrates the detector or sensing elements in addi-
tion to automatic calibration of the smoke detector via battery charge drop-off.
In the event of a false alarm, e.g. after forgetting to press the test but-
ton, wait for at least one hour until you press the test button for cali-
bration (1 hour calibration lock).
Monitor batteries
The battery-powered devices (room unit, room temperature sensor, meteo
sensor, radiator control actuator, water detector, handheld control, door/win-
dow contact, smoke detector and M-bus meter) constantly monitor battery
charge. If batteries are low, a message is forwarded to the central apartment
unit.
