Connection instructions
• Use only the supplied mating part (colour-coded brown) to the plug for the connection.
• The connection must be done by a qualifi ed electrician.
• The internal switch contact is designed for a max. DC voltage of 24 V or a max. AC voltage of 230 V.
• The maximum current load is 5 A at 230 V AC and 10 A at 24 V DC.
• The internal switch contact is a changeover contact; in case of alarm, therefore, the switching state may be
queried as „opened“ or „closed“.
13.4. FALSE ALARM OF THE SMOKE DETECTOR
• By interrupting the power supply for a few seconds, the smoke detector is reset and the system returns to
normal operation.
13.5. SMOKE DETECTOR - BATTERY CHANGE
CAUTION:
The use of rechargeable batteries is not permitted!
The life of the battery is highly dependent on local conditions such as temperature, temperature fl uctua-
tions, humidity and the number of test alarms/alarms, among other things. In the case of lithium, this is up
to 5 years. The smoke detector announces a necessary battery change approx. 30 days in advance (see
10.2).

13.6. SMOKE DETECTOR - MAINTENANCE
ATTENTION
In accordance with DIN 14676 the proper function of the smoke detector must be checked at least once
per year.

• The smoke detector is completely tested with the LED test button (fi g. 1): battery function test, electronic
smoke chamber test and a test of the evaluation electronics.
• After releasing, the test alarm resets itself
• Following a successful test, the alarm is silenced and the LED fl ashes every 45 seconds - the smoke detector
is ready to operate
• If the test failed, see error and alarm overview for error analysis
Self-test
• The smoke detector carries out an automatic self-test, in which the evaluation electronics as well as the volt-
age and the internal resistance of the battery are checked about every 45 seconds.
• This check is signalled by a short fl ashing signal of the red LED.
