4. Now mount the casing bottom, use the enclosed fixing

material.

5. Then connect the enclosed 9 V bloc battery to the bat-

tery clip and insert the battery in the battery compart-

ment.

6. Now re-insert the appliance in the casing (please note

to place the holding clips of the casing bottom into the

openings provided for this purpose) and tighten it

clockwise.

Caution! The system is provided with a safety feature

which prevents the smoke detector from fixing at the

rear wall of the casing unless a battery is inserted. If the

smoke detector does not fit in the holding clips, please

make sure to have installed the battery correctly and

inserted in the battery compartment.

Self test function

This function allows to check SD 5Y for proper functio-

ning at regular intervals. Press the test button for

approx. 4 s until the alarm sounds. The self test program

is activated when pressing the test button. The alarm

indicates that the electronic circuit (hooter and battery)

function properly. Please carry out the self test function

once a week for safety reasons in order to ensure proper

functioning. If no alarm is given, the reason is in most

cases a discharged battery. In this case please replace

the battery (refer to "6. Battery replacement").

Battery warning system

Under normal circumstances the battery is ready for ser-

vice for at least 5 years. The SD 5Y smoke detector is

provided with a battery warning system. If the battery

becomes weaker, the appliance generates a warning

sound at intervals of 30-40 s. This warningsound will be

given for at least 30 days. s soon as you can hear this

sound, please replace the battery immediately.
