Application example of
ESM
Siemens
Building Technologies
Once ESM is activated, "ES" is displayed on the SED2 BOP (Basic operating
Panel). ESM activation can also be assigned to one of the relays of the SED2.
The SED2 firmware offers ESM as a standard feature which can be enabled via a
parameter and also appropriately parameterized. We envisage a number of typical
applications for the ESM function. The following example shows a typical SED2
application in a shopping mall, including ESM:

Alarm Control Panel
• Several air handling plants are installed in a shopping center, using several
SED2 for the supply and extract air fans
• In normal operation, the Desigo system delivers the switch-on command and
setpoint to the VSD via bus
• If the fire alarm center activates ESM, the SED2 will start to operate with the
maximum speed at 50 Hz and suppresses the protective functions and error
messages as described above
• The plant will switch to overpressure operation in order to keep the rooms free
from smoke
