How can I check the functionality of a smoke alarm?

When the test button is pressed, the indicator light flashes regularly to show that the smoke alarm is working. With the Ei650i, the LED is automatically reduced from 10 p.m. to 6 a.m.. With the Ei6500-OMS there is no signalling during normal operation. During this time, fault messages are suppressed on the Q smoke Genius H or permanently signalled on the Ei6500-OMS. In the event of an emergency, an alarm is still triggered.
