10.1 Requirements
The sound pressure level of the surroundings in which an audible alarm device is to be installed must be
•
measured.
The sound pressure level of the alarm device must be at least 65 dB and must be +10 dB higher at all
•
locations than the sound pressure level that was measured for the surroundings. If necessary, several alarm
devices may have to be planned.
•
The sound pressure level of the signal tone (e.g. DIN tone) that is also going to be used later for alarm
output in these surroundings, must also be measured.
The signal tone must be clearly audible above the background noise. In case of similar frequencies, a
•
different signal tone must be chosen and/or the alarm must be signalled with an additional optical alarm
device.
In accordance with DIN 33404-3, an alarm signal and/or signal template for alarms (e.g. comprising
signal tone + voice output) must always begin with the DIN tone. Then a voice message may be
output.
If possible, the audible alarm devices should be configured in control zones with a low control zone number.
•
Low control zone numbers are activated quicker than high control zone numbers. Relay/LED outputs should
have higher control zone numbers than alarm devices. As many loop activations as possible should be
assigned to a control zone.
•
Synchronisation is carried out at all esserbus
The gap between the synchronisation signals must be coordinated with the signal templates that were
•
aggregated in the tools 8000 programming software (e.g. consisting of signal tone + voice output).
If an alarm device is replaced with the device, all the activations are transferred. If an alarm device is
•
replaced by a device from another zone, all activations are deleted, including the activations in the sectors.
