Schuch e856 Series Operating Instructions Manual page 15


Alert the emergency light unit to the presence of a new battery:
Open and close the lid of the battery box twice within a 60-second period. Opening and closing the
case must occur within 10 seconds of each other.
If this procedure is done correctly, immediately after the battery box is closed for the second time,
the signal LED will display an acknowledgement light. The five-second long red-green
acknowledgement light confirms that a operational life test will be conducted 12 hours later.

Close the lid of the battery box with the screw plug.
Should a battery capacity fault be present when the acknowledgement light is displayed, more
operational life tests will then be carried out at 52 week intervals. If no fault was detected in the battery
capacity, the interval until the next regular operational life test is unaffected.
6.5 Replacing emergency light unit and LED-reflector
Replacement of the emergency light unit and LED-reflector with mounted LED-modules has been
described in the separate instructions which can be found attached to the spare parts to be
supplied.
6.6 Environmental advice
This device has got an accumulator which among other things contains
cadmium which is ecologically dangerous. There is a particular
designation for this purpose.
The people operating this device are obliged by law to return
accumulators which have become waste and which contain any pollutant
materials to organizations which are in the hands of the vendors or
waste disposal holders being under public law.
6.7 Placing the fitting out of operation
To place the light fitting out of operation the battery must be separated from the emergency light unit.
In order to avoid unnecessarily removing the emergency battery, disconnection should take place
immediately after the interruption of the power supply.
During storage there will also be a gradual discharge of the battery. If the voltage drops below a
certain level the battery will no longer be detected by the emergency light unit. Thus a battery contact
failure will be indicated although the connection to the battery still exists. In this case, the emergency
battery is to be removed as described in Section 6.3 and to be charged separately from the light fitting.
A charging voltage of 6 V and a charging current of 80 mA must not be exceeded. Under these
conditions is a discharged emergency battery sufficiently charged within just 5 minutes for it to be
reinserted into the light fitting, where it can continue to charge.
 To avoid any damages the battery should not be stored for more than 6 months
! without being re-charged periodically!
