2.1 Exclusion of liability
The user of the SED2 variable speed drive must be aware that fire/emergency op-
eration may only be activated should crucial events occur (e.g. fire), where contin-
ued operation of the motor (fan) is mandatory to ensure smoke and heat extraction,
for instance, in order to facilitate the evacuation of people.
When triggering fire/emergency operation, certain alarm and fault status messages
of the SED2 (e.g. overtemperature of SED2, breakdown of bus communication) will
be suppressed. In the case of other faults (e.g. overvoltage or overcurrent), restarts
will permanently be triggered. Suppression of the protective functions shall ensure
that – during fire/emergency operation – the motor continues to run as long as
possible.
When using this operating mode, damage to the SED2 itself cannot be excluded,
be it due to failure of internal components or fire caused by excessive heat. In addi-
tion, it must be taken into account that – due to the parameterized behavior of the
SED2 – other HVAC plant components can also be damaged during fire/emer-
gency operation. This includes air dampers, for example, which can be damaged
as a result of overpressure (e.g. when the maximum motor speed is parameter-
ized). Such damage can lead to HVAC plant malfunction or failure – a fact to be
considered when triggering fire/emergency operation.
For these reasons, Siemens Building Technologies assumes no responsibility for
any faults, malfunctions and damage of the SED2 itself or of any other types of
components used in the relevant HVAC plant, or for direct or indirect damage re-
sulting from activation of fire/emergency operation.
The correct functioning of fire/emergency operation depends on the right selection
of the HVAC system components of which the SED2 constitutes only one compo-
nent. Plant used in vital sectors, such as ventilation plant that need to mandatory
and constantly deliver a certain amount of outside air, must be approved by the re-
spective authorities.
Fire/emergency operation can be triggered via one of the six digital inputs DIN1...6.
The BOP display shows alternately “ES“ and the motor’s frequency.
Fire/emergency operation can be deactivated any time via the digital input that was
used for activation. Then, the SED2 will resume normal operation as parameter-
ized.

3 Introduction
3.1 Smoke and heat extraction in the building
”There is no smoke without a fire”. This old proverb can still be applied to our time
– and the order of the 2 risk factors ”smoke and fire” is correct too. A number of
fires in recent times have demonstrated that, very often, smoke poses a greater
threat to people than the fire itself. This shall be in indication of the importance of
smoke when discussing the safety of people in the case a building fire has broken
out.
On the one hand, strong smoke limits visibility or produces toxic gases, which
make breathing much more difficult so that escape routes can no longer be used
without wearing appropriate clothing. On the other hand, the accumulation of gases
produced by the fire will lead to enormous heat concentrations near the source of
the fire so that flashover to other spaces or plant can occur.
The necessity of smoke and heat extraction is uncontested. In general, however,
contractors must first be persuaded to include this requirement in their planning
work and to approve the investment since this feature does not constitute part of a
HVAC plant’s comfort requirements, but is ”only“ considered as a ”preventive
measure”.
Present national fire protection guidelines and standards, which sometimes even
give consideration to regional needs, partly define the requirements placed on
smoke and heat extraction in buildings. Proven applications come primarily from
Australia (S/NZ 1668.1-1998) and the U.S. (ASHRAE publication, Design of Smoke
Management). For European countries, EN 12101 lays down the requirements for
smoke and heat extraction components and the methods applied to differential
pressure systems (overpressure plants) in buildings.

3.3 Interplay of ventilation plant and smoke and
heat extraction in the event of fire
The illustration below shows a possible scenario in the event of fire and the inter-
play between ventilation plant and smoke and heat extraction. According to the
scenario chosen, a fire broke out on the floor in the middle of the building. In prin-
ciple, the change from ventilation mode (comfort mode) to fire mode (smoke ex-
traction mode) can take place automatically via the fire alarm center, or through a
key switch on the fire alarm panel.
In both cases, the ventilation plant in section 2 will be shut down first of all. Both
fire protection and smoke extraction dampers will be closed or opened as shown.
Then, the fume gas fan (smoke extraction) in section 3 will be activated. The hot
and usually toxic fumes will thus be vented to atmosphere. The resupply air duct
and the open damper ensure that the space will be adequately vented.
The fire protection dampers on the respective floor prevent smoke from reaching
the other floors via the supply and extract air ducts. However, open doors, passage
ways or other openings between the floors and the stairwell or lift shaft allow
smoke to spread. In order to keep escape routes and the other floors free from
smoke as long as possible, ventilation plant in these zones will purposely be oper-
ated under overpressure.
In zone 1 (stairwell), overpressure of 50 to 100 Pa is produced with the help of a
differential pressure sensor and a speed-controlled fan (using a PID controller).
Overpressure prevents smoke from entering the stairwell. Pressure changes
caused by the opening and closing of doors are compensated by the control sys-
tem, which also ensures that doors can still be opened in case pressure differen-
tials exceed a certain level.
The supply air fan in zone 2 will also be activated, producing overpressure like in
the stairwell. Naturally, differential pressure control could also be employed. But in
most cases, the fan operates at a fixed speed.
The interplay of smoke and heat extraction and ventilation plant pursues the follow-
ing targets:
•To minimize the amount of smoke and heat, the fume gases produced by the fire
shall be conducted to atmosphere as quickly as possible.
•Overpressure operation of the ventilation plant shall ensure that escape routes
and neighboring spaces will be kept free from smoke as long as possible.

Building Technologies Introduction 23.10.2007
3.4 Operation of SED2 in the event of fire
The new firmware V1.40 actively supports operation in the event of fire. The focus
is clearly on the above mentioned overpressure plants, which can be easily imple-
mented through the use of speed-controlled fans. The change from comfort to fire
operation is accomplished by the Essential Service Mode (ESM). For use with the
SED2, this function has been completely revised and extended.
The ESM function was also available with former firmware versions of the SED2,
but has been constantly optimized based on experience made in the field and
feedback received from the Regional Companies (RC). This means that V1.40 in-
cludes all findings made thus far so that the SED2 also represents state of the art
as far as ESM is concerned.
ESM can be activated via digital inputs DIN1…6. Hence, the ESM function must be
assigned to one of these inputs.
Typically, the signal is delivered by the fire control panel. In that case, ”ES” appears
on the BOP display, which alternates with the motor’s frequency.
When the command for ESM is deactivated again, the SED2 will resume normal
operation.
The primary objective of ESM is to ensure fan operation “under all circumstances“.
As soon as ESM is activated, the SED2 starts its operation independently of the
operating state predefined by the building automation and control system. This
means that ESM is given priority over normal operation. In addition – when us-
ing ESM – the protective VSD functions (soft errors and warnings), such as over-
temperature or faulty communication, will be suppressed and the hard errors, such
as overvoltage and overcurrent, acknowledged an infinite number of times and the
motor restarted. The hard errors must not be suppressed and ignored!
It is possible to define any setpoint as the ESM setpoint. The flexibility of the SED2
allows this unlike other competitor drive that can only supply a fixed frequency set-
point in Fire-Mode. However, a fixed-frequency (e.g. maximum frequency) is the
most common setpoint and this can easily be configured.
Sometimes, ESM also calls for controlled operation (internal PID), when full over-
or low-pressure operation is not permitted because it shall still be possible to open
or close doors. When using ESM, it is also possible to reverse the motor’s direction
of rotation.
For that purpose, V1.40 offers a new parameter with 2 control words. These control
words are used to define the behavior in ESM. The following applications can be
implemented, either individually or in combination:
•Running to a defined fixed speed
•PID control with a defined fixed setpoint
•PID control with a preselected setpoint via analog input or bus
•Reversal of the direction of rotation

Building Technologies Introduction 23.10.2007
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:

•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

4.3.1 Description
•In normal operation the SED2 is controlled from the Desigo PX via bus commu-
nication using the PTE module.
•In case of fire the fire control panel signals this to the SED2, it is going in the
ESM mode and the setpoint is still coming from the Desigo over the bus.

•The hand mode will be disabled automatically when ESM is active.
•The information “drive fault” and “drive running” is still available on the 2 relay
outputs.
On demand the information “ESM active” can be configured to a relay output.
•The fault F0072 (bus communication failure) will be ignored whilst ESM is active.
•In this example a DESIGO PX is used as the communication master but any
communication (FLN, P1, N2) could be used just as effectively.
