One short beep app . every minute indicates that the battery is weak and must
be replaced .
Two short beeps indicate malfunction due to background light or outer
interruptions of the smoke chamber .
Three short beeps indicate technical malfunctions .
Four short beeps indicate that the smoke alarm is dirty and must be cleaned .
A continuous sound indicates that there is smoke in the detector .
Visual signal
One flash every eighth seconds indicates normal operation .
Two flashes every eighth seconds indicate reduced sensitivity (pause function) .
A continuous flash indicates smoke detection .
How to stop the alarm
One short beep app. every minute:
Replace the battery . (See further under "Replacement of battery") .
Two short beeps:
Remove the background light or outer interruptions which causes the
disturbance of the smoke alarms operation .
Three short beeps:

Note: Modifying or tampering with the internal components of the smoke
alarm may cause malfunction and will invalidate the warranty .
Four short beeps:
Clean the smoke alarm . (See further under "Maintenance") .
Continuous signals (both visual and acoustic):
Alarm for smoke detection / fire .
(The alarm will sound as long as there is smoke in the detector .

Mounting
The smoke alarm should be fitted using the enclosed
mounting bracket, which is to be mounted in the
ceiling with one screw only (screw and plug for 5 mm
drill enclosed – please use a special plug for plaster
ceilings) .
When the bracket is fixed, the smoke alarm is attached with a click . It is now firm
but can be turned for adjustment around the point to which it is attached .
Replacement of battery
The mounting plate makes it easy to pull down the smoke alarm for cleaning and
for replacement of the battery . As an extra safety precaution, the smoke alarm
cannot be mounted without a battery . The smoke alarm requires one 9 VDC
battery, (included – mounted in the battery-compartment) .
Please note: The smoke alarm normally operates up to 10 days from the first
indication of low battery .
Please note: At first time installation simply remove the plastic strip between the
terminals and the contact before mounting the smoke alarm .
Note: For optimal detection the smoke alarm should be installed in a suitable
location as described above .
After mounting and after every battery change, test the smoke alarm by pressing
the red test button until a penetrating, clear signal is heard . Make sure that
the red test button flashes every eighth second . When the alarm is set-off, a
penetrating, rapidly pulsating signal is given out (min . 85dB/3m) . The alarm can
be stopped by pressing the red test button .
Maintenance
The following guidelines will help you care for the JACOB JENSEN
so you can enjoy using it for many years .
1 . Keep the smoke alarm dry at all times . If it becomes wet, wipe it dry
immediately and remove the batteries . Liquids can contain minerals that might
corrode the electric circuits .
2 . Use and store the smoke alarm only under normal temperature . Temperature
extremes can shorten the life of electronic components, damage the battery
and distort or melt plastic parts .
3 . Handle the smoke alarm gently and with care . If it is dropped, circuit boards
can be damaged, resulting in malfunction .
4 . Keep the smoke alarm free from dust and dirt to avoid the premature wear of
parts .
5 . Clean the smoke alarm by wiping with a soft cloth . Do not use aggressive
chemicals, cleaning solvents or strong detergents .
6 . Use only fresh batteries of the required size and type . We recommend Alkaline/
Top Grade batteries only . Always remove old or weak batteries as they might
leak chemicals that will destroy the smoke alarm .
7 . Modifying or tampering with the internal components of the smoke alarm may
cause malfunction and will invalidate the warranty .
