Alecto SA20 Mode D'emploi page 12

USING, TESTING AND MAINTENANCE:
Using:
The smoke detector works if the 9V battery has been placed and the SA20
has been mounted to the ceiling. The unit can only be mounted to the plate if
the battery has been installed. The LED underneath the test button will now
flash ± every 30 seconds. Once smoke is detected, the alarm will sound.
Once the smoke disappears, the smoke alarm will stop automatically
Hush function
The Hush function allows the user to decrease the smoke detectors sen-
sitivity during an alarm. By pressing the "HUSH/TEST" button the smoke
detector is decreased for a period of 9 minutes. The red led flashes 1x every
9 seconds in Hush mode. After 9 minutes the smoke detector resets to its
default sensitivity. For example, this can be used when the smoke detector
gives alarm during cooking.
Time-out function:
The time-out function allows you to preventively lower the sensitivity of the
smoke detector. By pressing the "HUSH/TEST" button without an active
alarm, you reduce the smoke detectors sensitivity for 9 minutes. The red LED
lights up 1x every 9 seconds during Hush mode. After 9 minutes the smoke
detector resets to its default sensitivity. You can use this mode for example
when you know that a situation (for example: cooking) will product smoke and
there is no danger.
Test:
Hold the test key for at least 5 seconds. The operation is still correct if you
hear 2 or three signal tones. Check the smoke detectors weekly. In alarm
status the smoke detector will generate about 85dB(A). Do not use candles,
open fire or cigarettes to test the smoke detector.
ATTENTION:
If the cause of an alarm is unclear, assume it's caused by fire. Im-
•
mediately evacuate the building.
• Keep the smoke detectors out of range of children.
• Protect against dust during rennovations. Without protection the
smoke detectors will lose their functionality.
Maintenance:
The smoke detector is maintenance-free. In very dusty rooms they may be
cleaned by vacuum.
PLAN AN ESCAPE ROUTE:
• Make a map and mark all locations of doors and windows and a possible
escape route. Note that you may need an escape ladder on high floors.
• Ensure everyone in the house knows the sound the smoke alarms pro-
