A Status display
Status
Acoustic signal
LEDs
Test status
A repeated acoustic
signal sounds for
2-3 seconds and
then changes to a
continuous acoustic
signal for a further
2-3 seconds.
The red alarm status LED lights up first and then
the entire display goes out for one second until the
yellow fault status LED lights up. If the tests have
been run successfully, the product switches to the
normal operating status (green operating status
LED lights up permanently).
Alarm status
The acoustic signal
sounds continuously
with regular inter-
ruptions until the
alarm status ends.
If the CO concentration exceeds the permissible
value, the red alarm status LED lights up. The
power supply to the heat generator is interrupted.
Once the CO concentration falls back below the
permissible value, the power supply is re-estab-
lished and the red alarm status LED goes out.
Fault status
The acoustic signal
sounds continuously
without interruption
until the fault status
ends.
If the product experiences a malfunction, the yellow
fault status LED lights up first. If the malfunction is
not rectified within the specified time period, the
LED continues to light up. After the malfunction
has been rectified, the yellow fault status LED goes
out.
Operating status
(normal operating
mode)
The acoustic signal
sounds once after
power is supplied.
The green operating status LED flashes first. After
120 seconds, the LED lights up continuously. The
product is in normal operating mode
