ALARM TEST
The alarm must be properly attached to the base plate before it can be tested.
a) Press the test button in the centre and release.

b) The unit will give an audible alarm consisting of 2 cycles of 3 loud beeps, then stop

automatically.
c) The red LED on the alarm will flash rapidly during the audible signal.

NOTE: The test button accurately tests the alarm’s smoke sensing circuit, there is no need to test

your alarm with smoke. If your smoke alarm fails to give an audible test signal, please refer
immediately to the trouble shooting guide at the end of this manual.
WARNING: You should test your smoke alarm every month.
If your ST-632 is interlinked with other smoke alarms, we recommend that every individual smoke
alarm is tested during the monthly test.
a) Briefly press the test button in the centre of the smoke alarm and release.
b) The unit you are testing will give an audible alarm consisting of 2 cycles of
3 loud beeps, then stop automatically. The red LED on this alarm will flash rapidly (once per
second) during the audible alarm. All interlinked alarms will give an audible alarm consisting
of 2 cycles of 3 loud beeps, then stop automatically, indicating the test is complete. The red
LED on all interlinked alarms will not flash rapidly. If any alarm fails to self-test, see
Troubleshooting in the attached user manual.
