Maintenance
Changing the battery
The batteries should be changed at least once a year or immediately if the low battery alert sounds. When
changing the batteries, the alarm must
not
be dismounted.
1.
Open the battery compartment
(Fig. 8A)
while at the same time sliding the compartment cover downwards
(Fig. 8B)
. Do not dispose of the batteries with your household waste. You must recycle all used batteries.
Batteries may be returned free-of-charge to the point of sale or to your local collection point.
2.
Insert 3 new batteries
correctly (Fig. 9)
and make sure that the red pins are in contact with each battery.
The alarm confirms that the batteries are in place with a short sound.
3.
Close the battery compartment by placing the cover on the alarm and sliding it upwards until it pops in.
4.
Test the alarm right away (
see Operating test
).
We recommend the following 1.5 V alkaline batteries, size AA/Mignon Energizer E91.
Under normal conditions new batteries will last for around a year – depending on the number of tests. If
the alarm is subjected to high or low temperatures for longer time, or to high air humidity, battery lifetime
will reduced.
Testing the alarm
Check once a week that the alarm is working properly by briefly pressing down the
Test/Mute button
(Fig. 8B)
. The alarm will beep 2 or more times and the 3 LEDs
(Fig. (C)
will light up briefly. Afterwards the
alarm returns to its normal operating mode.
Cleaning the alarm
Loose dust inside the alarm can be through the vents using a vacuum cleaner. The alarm cover can be
cleaned from the outside with a lightly dampened cloth. Under no circumstances use of any detregent
containing ammonia or any other chemicals (such as cleaning agents or solvents) on or anywhere near the
alarm. Do not paint or varnish the alarm!
Alarm functions
The alarm is equipped with a battery monitoring system. Low batteries are indicated by the alarm starting
to beep and the yellow
Fault LED (Fig. (C)
flashing around every 60 seconds. The alarm will continue to
work in this condition for around another 7 days. You should nevertheless change the batteries as soon
as possible. In the event of an alarm, the device can be muted by briefly pressing the
Test/Mute button
(Fig. 8B)
.
