b) Alarm indicator on the ‘HMS 100 Z’
When an alarm is triggered the ‘
’ symbol should appear on the central unit’s display (select
display type ‘Aktuell’).
The smoke detector transmits a status signal to the control centre every 30
minutes, which serves to control the connection and also includes the battery
level.
c) Alarm indicator on the ‘FHZ 1000’
An acoustic signal is used to audibly indicate that an alarm has been triggered, while an
exclamation mark appears on the lower left of the display to optically indicate that an alarm has
been triggered.
d) Periodic monitoring and error display
You can find an overview of the smoke detector’s optical and acoustic output
in section 18.
You should check that the smoke detector is working once a month. To do this, press the test
button for approx. 2 seconds (press the button to the pressure point).
• If the acoustic signal sounds once and the LED blinks 10 times, then the smoke detector
is working properly.
• If, after pressing the button, only the LED starts to blink, then the smoke detector is faulty
and must be replaced.
• If no signals are emitted, then the batteries are flat. Replace the old batteries with a
complete set of new batteries.
