Short circuits between the Dupline signal conductors and the earth potential lead to
disturbances and have to be avoided. The correct polarity of the Dupline signal has
to be observed.
4. On insertion it must be observed, that the orientation of the PCB is so, that the 5-
pin terminal (C) runs into the five wholes of the base PCB (counted from center to
border). Please see also chapter 19 “Anschlussschema / Connection Diagram”.
5. Put the smoke detector into the base and lock it by slightly turning it clockwise.
14. Test Button / LED Indicator
With the test button which includes also the LED indicator, the test alarm can be re-
leased. After pressing the test button it will take approx. 11 s until the alarm signal will be
sent pulsing every 1.25 s via Dupline when using the smoke alarm object in ProLine. The
alarm siren responses with the same cycle time. The response time when detecting fire
approx. is 21 s.
Doing so, the internal operating readiness is signalled by the LED and the readiness on
the Dupline bus by switching the adjusted channel.
The LED indicates the condition of the device:
15. 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 3 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 13.1 “Choice of
Mounting Location” on page 8). Therefor install a sufficient number of smoke detec-
tors to ensure optimum protection.
• The DRD 3 is a smoke detector designed for the Dupline bus system and thus not
equipped with an acoustic alarm. The alarm indication is carried out via the Dupline
bus. How the smoke detectors are integrated into Dupline is described in the ProLi-
ne respectively ProLine
NG
manuals. They are available for free download on our ho-
mepage http://www.doepke.de/uk.
16. Maintenance and Care
To ensure proper functioning of the DRD 3, 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 1.25-s-pulses) as well as on the Dupline
Indicator
