Periphery components for ESSER FACP

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
• 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
®
PLus modules that are operated on a FACP.
• 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.
