16. Safety Instructions
• The smoke detector must not be painted.
• Smoke detectors do not extinguish fires. If an alarm occurs, the source of the fire
must be located and, if necessary, the fire brigade alerted.
• The DRD 2 responds to the smoke of a fire, not to the flame itself.
• The smoke detector only monitors a defined area in its vicinity and will not neces-
sarily monitor another room or another floor (see also chapter 13.2 “Choice of
Mounting Location” on page 8). Therefor install a sufficient number of smoke detec-
tors to ensure optimum protection.
17. Maintenance and Care
To ensure proper functioning of the DRD 2, please pay attention to the following points:
• Monthly test the function by pressing the test button. The alarm must be indicated
at the device (short blinking of the LED in 5s-pulses) as well as on the Dupline bus.
• Wipe the smoke detector half-yearly with a damp cloth.
• Replace the smoke detecor after about 10 years of service.
