9. Functions of the test button

The smoke detector switches on automatically after placing it in its
base. The control LED in the test button will flash red once per minute
in normal mode. With the test button, the following functions can be
carried out:
- By briefly pressing the button you can cancel an active alarm.
- Hush or Silence Feature:
The smoke detector has a Hush or Silence feature. If cooking or other
non-hazardous events cause an unwanted alarm, it can be tempo-
rarily silenced by pressing the test button for 1 second. The alarm
will enter a dormant period for 10 minutes. The red LED will flash
every 8 seconds to indicate the reduced sensitivity. At the end of the
hush period, the alarm will reset to normal sensitivity.
NOTE - If the smoke density increases during this period (i.e. from a
fire) the unit will return into alarm mode.
- You can test the smoke detector's function by pressing the test button
for 3 seconds. The alarm siren will sound, the control LED will flash
rapidly and a fire alarm signal is transmitted to all lisa receivers
within RF signal range.
