Maintenance - GEV Flammex FMG 4313 Bedienungsanleitung

8. You can test the functionality at any time by pressing briefly on the „TEST/SILENCE" button. The CO warning
signal sounds and the red „ALARM" LED flashes. This does not signal that there is excessive level of CO in the
ambient air. Instead, it confirms that the alarm is functioning correctly.
Functions
1. In normal, error-free operation, the green „POWER" LED lights up at regular intervals of 30 seconds.
2. Error alert: If the device gives an acoustic signal at intervals of 30 seconds and the yellow „ERROR" LED
flashes simultaneously, replace the entire alarm. The device has a sensor error. The sensor cannot be replaced.
3. Battery power warning: If an acoustic signal (beeping) sounds every 30 seconds and the yellow „ERROR" LED
is flashing simultaneously, battery power is low. In this case, you must change the batteries immediately. The CO
alarm is no longer functional in this state. To change the batteries, follow the steps under the MAINTENANCE
heading. You can suppress the acoustic battery power warning by pressing the TEST/SILENCE button for nine
seconds. During this phase, the yellow „ERROR" LED flashes continuously.
4. End of service life: The service life of the electrochemical sensor is approximately seven years. The end of
the service life is signalled with three beeps every 30 seconds, as well as a flashing yellow „ERROR" LED. This
indicates that the detector needs to be replaced immediately.
5. Carbon monoxide alarm: If the FMG 4313 detects a critical concentration of carbon monoxide, the alarm
gives the following signal: Four short acoustic signals, followed by a five-second pause and four more short
acoustic signals. Alongside this alarm pattern, the red „ALARM" LED flashes. This rhythm repeats for as long as
a dangerously high concentration of CO is present in the ambient air or until the alarm is suppressed by pressing
the TEST/SILENCE button. For information on the procedure to follow in the event of an alarm, see the chapter
entitled „Actions in the event of alarm".
6. Mute CO alarm: While the CO alarm is active, you can mute the acoustic signals by pressing the TEST/SILENCE
button for five minutes. The red „ALARM" LED continues to flash during this time. If the CO content is still above
45 ppm after the time has elapsed, the acoustic signal pattern sounds again. Note: In the event of an active CO
alarm, the first signal pattern is somewhat quieter (<85 dB) than those that follow (>85 dB).

Maintenance

Changing the battery:
The batteries will not usually need to be changed until after around seven years. This timeframe can vary
depending on environmental influences. Important: Change the batteries immediately if the battery power
warning sounds (battery power warning is signalled by two short beeps accompanied simultaneously by the
yellow „ERROR" LED flashing every 30 seconds). To change the batteries, please follow these instructions:
1. Open the battery compartment by pressing on the arrow (fig. 8) and sliding the compartment cover
downwards. Do not dispose of the batteries with your household waste. The end user must recycle all used
batteries. Batteries may be returned free-of-charge to the place of sale or to your local collection point.
2. Insert two new batteries, ensuring that the polarity is correct (fig. 9), and make sure that the pins located in
the battery compartment are pressed down by the relevant batteries. The alarm confirms that the batteries are
in place with a short beep.
3. Close the battery compartment by placing the cover on the alarm and sliding it upwards until it clicks into
position.
4. Test the alarm immediately (see Function test).
Function test:
Check once a week that the alarm is working properly by briefly pressing the Test/Silence button (fig. 7). The
alarm beeps loudly and the red „ALARM" LED simultaneously flashes. The alarm then returns to its normal
operating mode.
Cleaning the CO alarm:
Loose dust on the inside of the alarm can be drawn out from the outside by using a vacuum cleaner to suck
through the air vents. The casing can be cleaned from the outside with a slightly damp cloth. Under no
circumstances should a household cleaner containing ammonia (liquid ammonia) or other chemicals (such as
