FDSB291 signal base
The signal base is installed in place of the standard base and adds 2 horn output components
to the FDOxxx smoke detector. The detector can then be used to activate a warning or
evacuation sound.
The signal base has two volume settings (per component/parameter set).
The FDT241 and FDT221 heat detectors cannot actuate the signal base.
The signal base can be actuated across the whole system.
FDS221 Alarm horn (sounder)
The sounder has 2 output components which can be used to activate a warning or evacuation
sound.
The sounder has three volume settings (per component/parameter set). The sounds are con-
figured in PLAN D100:
The different sounds are differentiated by the tripping criterion (level 1 and level 2). The crite-
ria are listed in order of priority. If both sounds are triggered, the sound with the higher priority
is actuated.
If required, the criteria can be implemented by means of virtual inputs/outputs (VEA). Exam-
ple: With alarm organization, a different sound or volume can be used for the pre-alarm than
for the main alarm.
The sounder can be actuated across the whole system.

Calculating the maximum number of elements and length of lead
Technically, the possible length of line depends on what cable you are using (capacity and
resistance), as well as the load imposed by buzzers and sounders.
Threshold values for FDnet:
Maximum 180 ohms per loop and/or spur and maximum 330 nF for shielded and 500 nF for
unshielded lines.
