2. Function and design of the EFD Plus Smoke Aspirating System
2.1 Short description
The EFD Plus Smoke Aspirating System has been designed for installation in enclosed
switch cabinets and is a compact unit that is able to detect a fire in its early stage.
Fire detection takes place via sensors to be adjusted for the anticipated fire characteristics
(automatic fire detectors).
A EFD Plus Smoke Aspirating System can monitor up to 5 cabinets at the same time.
Alarms and faults can be transmitted via potential-free contacts or optionally via the CMC-TC
with I/O unit to a superordinated location (monitoring or control device).
The compact smoke aspirating system with a space requirement of only 1 unit can be
installed in any free slot of a 19" switch cabinet system. The device is easy to install and
cheap to maintain.
The EFD Plus smoke aspirating system is prepared for the combined operation with the
extinguishing system DET-AC Plus Slave. Up to 5 DET-AC Plus Slave can be attached to
the device.
Areas of application
The EFD Plus Smoke Aspirating System is used to protect high quality technical installations
whose high availability is a must.
These include:
ƒ
ƒ
ƒ
ƒ
IT, server and network technology
which must provide important data for the enterprise process and ensure the data flow
itself
Production controls
whose technology ensures the uninterrupted running of the manufacturing processes
Telecommunications installations
which ensure that the communication of the enterprise works without interruptions
Power supply and control systems
which ensure sufficient energy at the right time at the right place in the enterprise
The earliest detection of a fire together with potential extinguishing action ensures that
downtimes and subsequent damage caused by a technical fault are minimised.

2.3 Function
4
Via a pipe system(3) a fan (2)
constantly sucks air samples from the
area to be monitored and passes them
via the fire sensors (1) for continous
monitoring.
7
The sensors are monitored permanently
by the evaluation and control electronics (5) on the control card for functionality and potential
soiling.
When the first fire alarm criterion is reached, the evaluation electronics controls the process
programmed for this event: It displays the alarm condition on a display (7), if necessary
triggers the transmission to superordinated systems, controls optional acoustic and optical
alarm devices.
When the second alarm criterion is reached the relay “extinguishing” is triggered electrically
after a preset analysis time. Additionally a connected fire extinguishing system DET-AC Plus
Slave can be actuated via the CAN-bus connection.
The extinguishing agent tank is protected against overpressure. The filling level monitor
integrated into the extinguishing agent tank reports a loss of extinguishing agent to the
evaluation electronics which indicates this fault (extinguishing agent loss) on the display and
if necessary transmits it to superordinated systems.
The power supply for the Smoke Aspirating System is secured from 2 sources. Once source
is a power supply unit (6) which also charges the batteries for the emergency power supply
(4). The other source is the emergency power supply which is switched in parallel. The
emergency power supply is designed for the uninterrupted operation of the system
for 4 hours.

EFD Plus
Smoke Aspirating System
The control and display of the current state of the device is achieved via the integrated
control unit. This has both LED indicators and an LCD display to display the current status.
The LEDs are used to display collective conditions, whereas the individual conditions are
displayed in detail as clear text on the LCD.
If there are several messages, the cursor keys can be used to switch between them. The
existing messages are sorted in accordance with their priority and the order of arrival. If the
cursor keys are not used for a duration of 30 seconds, the display switches back to the
normal state.
The display of collective conditions via the LEDs of the control unit is independent of the
content of the LCD and therefore independent of the scrolling using the cursor keys. It
always represents the current system state.
Besides the cursor keys the control unit has another two keys for resetting stored messages.

2.4.1 Door contact (Blocking of a connected extinguishing system)
Via the input "door switch" the release
of the extinguishing system is
blocked.
For each cabinet the door contacts
are connected to the respective
device. When actuating the door
contacts by opening the door always
the entire fire detection and
extinguishing system is blocked (up to
max. 5 server cabinets). This is
necessary because the build-up of a
sufficient concentration of
extinguishing agent cannot be
guaranteed with the door open. This
blocking is displayed in the LCD and via the green flashing operating LED, also the relay
“collective fault” switches. No yellow fault LED is on or flashing.
Caution!
All extinguishing requests registered during the condition "Extinguishing system
blocked" (= blocking of the extinguishing system) place the device into the status
"extinguishing system blocked" but do not cause the extinguishing action to be
started.
Input "door switch" as RJ12 connector
One input "door switch" (5) is designed for the model
Rittal 7320.530 (see fig. 1). As termination an RJ12
d
connector with a resistor is provided (see fig. 2).
With door switches in old
version (fig. 1, c) to the 22kΩ
terminating resistor a 22kΩ
c
resistor is switched parallel at
Fig. 1
the output of the last switch, as
soon as all doors are closed, so that with normal operation a
Fig. 2
resistance of 11kΩ adjusts itself. With open door a resistance of 22kΩ
adjusts itself.
With door switches in new version (fig. 1, d) a 1KΩ terminating resistor is plugged into the
output X2 of the last switch. If all doors are closed, in normal operation only that 1KΩ
terminating resistor is in the monitoring circle. With each door, that is opened, a 22kΩ resistor
is switched parallel to this 1KΩ resistor.
Via the connection X2 several
door switches of this type can be
switched in series (max. 10 door
switches).

Selection of door contact via hardware switchover
The door contact is also integrated in the software, so that it must be differentiated between
the old grey door switch c and the new transparent door switch d.
The respective door switch is selected via the hardware as follows:
• Function of old door switch: On the control card at the DIP switch S3 of the slide switch 6
is set on OFF and the slide switch 7 is set on ON
• Function of new door switch: On the control card at the DIP switch S3 of the slide switch
6 is set on ON and the slide switch 7 is set on OFF
Note: After change of the slide switch position the device must be switched dead completely,
meaning the battery must be short-time disconnected (hardware reset) if necessary.
Afterwards the system is to be set in operation.
Information: The LED of the functioning switch does not shine
Caution!
In each case either the RJ12 connector or the two-pole plug may be used as input
"door switch".
Caution!
If a fire alarm is released with blocked fire extinguishing system (indication
"Extinguishing system blocked") and the blocking is abolished with queued alarm,
e.g. by closing the door, the extinguishing action is started one second after
abolition of the blocking.
2.4.2 Manual release / manual alarm
By operating an optional connectable push button the fire alarm is released. If an
extinguishing system DET-AC Plus Slave is connected also the extinguishing action is
triggered manually.
Switch open
Switch closed
= Quiescence
= Alarm
The resistors must be dimensioned as follows:
ƒ RA: 1K8 Ohm, 0.5 Watt (included in delivery)
ƒ RK: 470 Ohm, 0.5 Watt
To release a fire alarm / to trigger the extinguishing action the push button "manual release"
must be operated for at least 1 second. The release is always direct and independent of the
condition of the automatic detectors. The programmed dual detector dependency does not
apply for the manual release.
The release via the input "manual release" is suppressed during an open door contact (see
chapter 2.4.1) or if an external blocking is present.
The alarm message of the manual release must be reset manually (see chapter 3.5.2).

AI04 09/2010 - page 12/64
EFD Plus
Smoke Aspirating System
2.4.3 External power supply
For external consumers there is a two-pole connection (US) with an output voltage
of 21-29 V DC. This output is protected by a fuse and supplied with emergency current. If the
power supply is exclusively from the battery (during mains failure) the voltage can drop to 21
V DC! With less than 21 V DC the voltage is switched off automatically (deep discharge
protection).
2.4.4 Relay outputs
The device has 4 relay outputs with one change-over contact each:
(connection diagram see chapter 2.4.)
Relay 1 Pre-alarm
A detector has triggered. The relay remains energised until the
(NO)
alarm criterion is no longer present and the reset key button
has been pressed.
Relay 2 Fire alarm
The second detector has triggered or the manual release was
(NO)
actuated. The relay remains energised until the alarm criterion
is no longer present and the reset key has been pressed.
Relay 3 Extinguishing
The relay is energised parallel to the release of the
released
extinguishing function and remains energised until the reset
(NO)
key is pressed.
Relay 4 Common failure The relay is permanently energised. In case of a fault (exc.
(NC)
mains / battery fault) the relay drops out.
The relay operates also with blocked fire extinguishing
system, in order to forward the info „release did not take
place“.
The relays 1-3 stay permanently energised when triggered. The maximum switching voltage
is 30V with a maximum switching current of 0.5A and a pure resistive load. Inductive or
capacitive loads require external protective circuits which must be provided by the operator.
Caution!
If the CMC-TC with I/O unit is connected via RJ12 connectors, the relay outputs
must not be used!

Installation notes
Caution!
ƒ
ƒ
All tasks developing smoke and dust (smoking, soldering, cleaning etc.) must
be prevented during installation and commissioning of the device!
It is possible for an alarm to be triggered during commissioning!
It must be ensured that any controls downstream from the device
(e.g. extinguishing systems or transmitted messages) have been switched off
beforehand!
The device can be installed in any free slot of a 19" switch cabinet system to be protected,
but preferably on eye level, in order to ensure a simple reading off of the messages and
indications.
Care must be taken that the sampling pipe at the intake side of the air conditioning unit is
installed vertically and the bores of the sampling pipe are directed against the air flow!
Caution!
After installation a smoke response test must be carried out (see 7.1.6)!
Before the trigger test the door must be opened to block the extinguishing action.
This must be checked via the green flashing operating LED and the indication
"extinguishing system blocked" in the display.
After the trigger test at least 2 minutes must pass to allow the test gas
concentration in the detector heads to dissipate and the alarm must be reset.
No fire message (red LED) may be indicated before the blocking is cancelled by

ƒ Attach the plug of the batteries for emergency power supply to the free plug contact.
Thus the batteries are attached in 24 V function! (see figure 1)
Caution! The battery must only be connected if it is immediately followed by connecting
the mains supply since otherwise the batteries will be discharged!
ƒ Screw the cover plate of the battery compartment back
ƒ Slide the device horizontally onto the sliding rails. Ensure that the device slides in easily
without jamming up to the stop of the font panel at the frame
ƒ Attach the device to the front panel using four of the screws and block plastic washers
included through the holes of the front panel in the 19" frame (see figure 2)
ƒ Install the sampling pipe (see chapter 3.2.3)
ƒ Connect the device to the 100/240 V power supply
ƒ Press the button "Reset PS (power supply)"

Installation notes for the sampling pipe
Note
The sampling pipe system is a self sealing and self-locking pipe system.
With the plugging together of pipe and fitting the pipe union is completely done.
Caution!
Sampling pipe connection:
• Ensure the correct connection of the sampling pipe (air intake) to the device!
Never connect to the air flow return (air outlet).
• An L-shaped plug-in connection (angle) with the opening facing downwards
must be fitted to the air outlet to comply with IP 20.
The vertical sampling pipe must be attached at a location aiding the
flow (bores of the sampling pipe directed against the air flow) using the
clamps. The bores may not be covered by the clamps!
The diagrams on the following page indicate the fans. It is assumed
that the fans on the side of the sampling pipe aspirate air from the
cabinet. The 4 holes in the sampling pipe must be directed away from
the fans towards the cabinet!
The sampling pipe is sealed with an angle and a plug at the bottom.
A trigger test using test aerosol must always be carried out!
(Caution, to do so block the potentially connected extinguishing
system, see 7.1.2)
Number of bores
The number of bores depends on the number of supervised cabinets.
The following table is to be considered:
1 cabinet = 4 bores
2 cabinets = 2 x 4 bores (= 8 bores)
3 cabinets = 3 x 4 bores (= 12 bores)
4 cabinets = 4 x 3 bores (= 12 bores)
5 cabinets = 5 x 3 bores (= 15 bores)
Caution!
The following figures are recommendations. Other arrangements for fans and air
conditioning devices might require a different position of the sampling pipe. The
installation of the device must always be coordinated with the operator. During
future changes of the cable configuration the bores of the sampling pipe have to
remain free. The pipe system must not obstruct the future cable routing within the
cabinet!

3.3 Installation and commissioning of additional electric devices
After the proper installation and commissioning of the EFD Plus Smoke Aspirating System
additional electric devices can be connected.
Caution!
Connection of additional electric devices: For the connection of additional
electric devices the following information must always be observed:
ƒ It is possible for an alarm to be triggered during commissioning!
It must be ensured that any controls downstream from the device (e.g. connected
extinguishing systems or transmitted messages) have been switched off
beforehand!
ƒ Before the functional test the door must be opened to block the potentially
connected extinguishing system. This must be checked via the flashing green
operating LED and the indication "extinguishing system blocked".
No fire message (red LED) may be indicated before the blocking is cancelled by
closing the doors, otherwise the potentially connected extinguishing system will
be released!
ƒ The conditions must be checked in accordance with the installation- and test
3.3.1 External alarm devices
External alarm devices, e.g. flashing lights and/or alarm horns (see also chapter spare parts
and accessories) can be connected to the relay outputs pre- and main alarm (see 2.4.4 relay
outputs). That max. current with 30 V DC amounts to 0.5 amp.
3.3.2 Push button for manual release
To connect the push button for manual release the sequence in the installation and test
report (see 7.1.3) must be observed.

The correct operating state of the EFD Plus Smoke Aspirating System is indicated by a
permanently illuminated green operating LED (1).
If a fire alarm or faults occur, they are indicated on the LCD display (2) and by fault LED (3)
or alarm LED (4).
The EFD Plus Smoke Aspirating System shall therefore be installed in a clearly visible
location and monitored by an overriding system, if necessary.
3.4.1
Alarm and fault messages
Alarm messages
The EFD Plus Smoke Aspirating System can implement two alarm levels with different
indications and controls via two sensors responding at different sensitivities. The respective
indications and their meanings are explained in the table "LCD display indications" below.
Fault messages
The EFD Plus Smoke Aspirating System monitors the most important functions itself. Faults
are indicated and can be queried via the potential-free contact.
If the door of the protected cabinet (e.g. Modulsafe) is non-transparent and therefore the
display is not readable possible faults can be read off from the CMC.
The respective indications and their meanings are explained in the table "LCD display
indications" below.
Caution!
In case of a fault the proper functioning of the device is not guaranteed. If a fault
message arrives it might not be possible to detect and extinguish a fire!
Therefore, the cause of the fault message must be immediately removed!
Caution!
Before the functional test the door must be opened to block the extinguishing
action of a potentially connected extinguishing system. This must be checked via
the flashing operating LED and the indication "extinguishing system blocked".
No fire message (red LED) may be indicated before the blocking is cancelled by
closing the doors, otherwise the extinguishing action will be initiated!

The display of messages from the event memory is identical to the message display of the
system. To indicate that this is a display from memory the text 'EMEM' is shown at the top
right. Unlike in the message display, messages are also entered in the event memory if a
state causing a message has been removed. The display of the current message is either by
way of a correspondingly different text message (Figure 5) or using the same message plus
the symbol
for current messages.

The number of the message is numbered from the start of the current event memory. I.e. the
oldest event still present in the memory has the number 1. If the event memory is full, the
next event overwrites the so far oldest event. During the next display of the event memory
the event previously carrying the number 2 now carries the number 1 (the stored events
move down to allow the new event to be inserted at the top). The numbering in the event
memory has no relation to the number shown for the event in the message display when the
event was still current.
In the display of the event memory one can change from any entry to the chronologically
oldest event by simultaneously pressing the two arrow keys 'UP' and 'down'. Likewise the key
'RESET EV' always leads to the chronologically recent event. If one keeps the respective
arrow key longer pressed while scrolling, the display continues to run automatically into the
selected direction, as long as the key remains pressed.

Apart from the monitoring of the operation hours of the batteries the system evenly monitors
the period of operation since the last maintenance. If this exceeds the maximum
maintenance interval, a failure message is generated (indication by LED "collective error"
and triggering of relay "collective error").
For resetting this message a fabricator reset must be carried out. For this purpose the
housing of the device must be opened. On the CPU board the key 'Reset' is to be pressed
for longer than 3 seconds. Afterwards the failure message to the maintenance interval is
deleted and the operation hours meter of the system reset. This resetting does not have any
influence on the monitoring of the period of operation of the batteries.

4. Behaviour during a fire
Caution!
This information does not replace the locally prescribed behaviour during a fire in
any way but serves as additional information about the behaviour during
alarms/fires or release of a connected DET-AC Plus Slave extinguishing system in
a cabinet protected by a EFD Plus Smoke Aspirating System!
Measures in case of an alarm in a cabinet monitored by a EFD Plus Smoke Aspirating
System:
• locate smoke formation; if smoke is recognisable, shut down server and disconnect
cabinet from the mains
• start fire-fighting actions, but only use suitable portable extinguishers (carbon dioxide fire
extinguishers)
Measures in case of an alarm in a cabinet additionally protected by a DET-AC Plus
Slave extinguishing system:
ƒ Always keep the cabinet doors closed during the hold time (10 minutes). If the
concentration required for extinguishing drops due to ventilation, any still existing source
of ignition might flare up again.
ƒ Shut off the energy supply of all consumers in the cabinet.
ƒ If no fire or smoke can be seen, the cabinet can be ventilated with extinguishing aids
(e.g. carbon dioxide fire extinguisher) at the ready.
Release of the DET-AC Plus Slave extinguishing system
The release of the DET-AC Plus Slave extinguishing system is described in the DET-AC Plus
Slave manual.

5. Control, service, maintenance and repair after release
The operator carries out the regular visual inspections at the device himself.
The maintenance and repair of the device is carried out by the Rittal Service or a specialist
company authorised by Rittal.
A specialist company authorised for maintenance and fault removal is a company whose
employees have been trained by Rittal in the EFD Plus Smoke Aspirating System. Normally
this is a member of the installation company or a specially trained employee of the operator
or a specialist company commissioned by him.
In case of improper handling and faulty or missing regular inspections and maintenance
Rittal does not accept any liability.
5.1 Regular inspections by the operator
Daily inspections (operator)
ƒ No fault may be present in the EFD Plus Smoke Aspirating System.
(operating state without fault or alarm: green operation LED is on, no yellow fault LED is
on or flashing).
Any faults present must be recorded and removal must be initiated.
Daily inspections may be omitted if it can be ensured that any faults are safely detected
elsewhere.
Monthly inspection (operator)
ƒ Sampling pipe and extinguishing nozzle must be free of external damage and the nozzle
must be free of contamination and obstacles in the spray
ƒ Sampling pipe connections must not be disconnected
Display air flow and compare with the value from the commissioning report to detect any
contamination. The max. deviation to the target value must not exceed 10 %.
Quarterly inspection (operator)
This should additionally investigate any constructive modifications (especially with regard to
the air tightness of the cabinet: the air exchange rate of the switch cabinet system to be
protected must not be greater than 10 % within 20 min) or changes in use, and the device
should be checked for the proper operation of the alarm, fault and control functions.

AI04 09/2010 - page 41/64
EFD Plus
Smoke Aspirating System
5.2
Tests, maintenance and repairs
Caution!
During maintenance work at the device an alarm may / should be triggered! It must
be ensured that any controls downstream from the device (e.g. transmitted
messages or shut-off device) have been switched off/bridged beforehand!
Caution!
Before starting maintenance work the blocking switch of all devices interlaced in
the system must be on „blocked“ position!
Semi-annual maintenance (Rittal or specialist company)
Visual inspection, complete service (e.g. test and, if necessary, clean sampling pipe, check
cover seal, replace filter for air flow sensor, if necessary, check air flow calibration and adjust,
if necessary) plus operational check.
The history memory must be checked for errors (see 3.5.3 “View event memory”).
Biennial maintenance (Rittal or specialist company)
At least every two years the EFD Plus Smoke Aspirating System must be serviced by Rittal
Service or a specialist company authorised by Rittal. During this maintenance the system is
fully tested and, if necessary, returned to the target condition. Non-observance of these
intervals may cause faults or false alarms and subsequent false extinguishing.
After 2 years, e.g. in the context of the first biennial maintenance, the batteries for the
emergency power supply must be replaced.
For the sensor inserts integrated in the EFD Plus a total lifetime of 10 years is recommended
when used within dry areas, free from dust and corrosive atmospheres. Regular inspections,
maintenance, if necessary cleaning and calibration are presupposed.
In individual cases, depending upon site conditions or type of sensor, shorter intervals for
replacement can be necessary.
Caution!
Fault indication for battery capacity: The fault indication of the available battery
capacity responds to a remaining capacity of less than approx. 70%. With a battery
replacement or with the initial commissioning it can come to the fact that the
message "Battery not full" appears, since the new batteries were stored for a too
long time. This indication disappears only, when a battery capacity of > 70 % is
reached.

Changeover of the language for indication and operation
Umstellung der Sprache für Anzeige und
Bedienung
Das Gerät kann in 2 Sprachen, Deutsch und Englisch,
kommunizieren. „Deutsch“ ist werkseitig voreingestellt,
kann aber über einen Dip-Schalter einfach auf
„Englisch“ umgeschaltet werden.
Für das Umschalten wird wie folgt vorgegangen:
ƒ Gerät von Netzversorgung und den Notstromakkus
trennen
ƒ Den Gerätedeckel abschrauben
ƒ Den Dip-Schalter (siehe nebenstehendes Bild) von
Position 4 „off“ (deutsch) auf „on“ (englisch)
umschalten.
ƒ Den Gerätedeckel anschrauben
ƒ Gerät wieder in Betrieb nehmen
Changeover of the language for indication and
operation
The device can communicate in 2 languages, German
and English. "German" is pre-set at delivery and can
simply be switched by use of a dip switch to "English".
The switching is proceeded as follows
• disconnect the device from mains supply and the battery backup
• Unscrew the cover
• Change over the dip-switch no. 4 from position „off“ (German) to „on“ (English)
• Screw on the cover
• Take device into operation again

Compatibility of devices of different series
Devices DET-AC Plus Slave of the old series (article number 90 7023) can principally be
attached to DET-AC plus Fire Extinguishing Systems of the new series (article number 88
9133), exactly the same devices DET-AC Plus Slave of the new series (article number 88
9214) can be attached to DET-AC plus Fire Extinguishing Systems of the old series (article
number 90 6744).
As the case may be that devices of the old series with an old firmware (version 1.2.2.0 or
older) cannot not be triggered (failure message “failure ignitation cap.”) or cannot trigger (no
failure message), the devices of the old series must at least be equipped with the firmware
starting from version 1.2.3.0 within a mixed network of devices of different series.

Connection power supply and data line
At first the mains supply is put on at the master device, then each slave device is attached to
the voltage output of the upstream device.
Only, if thereafter is no fire message at the display of the master device, the data lines may
be attached to the respective upstream devices.
Checking the network:
After the network is set up completely a message has to be generated at each device. Each
message must be examined at the master device.
It is recommended for it to operate the door contact of each device.
Reading out the condition of the respective devices
The display of the current condition of the fire extinguishing system takes place via the
master with the identification Z1 (DET-AC Plus active fire extinguishing system or EFD Plus).
On its LCD display the individual devices, after being selected, are indicated. The attached
device indicated by the message is to be identified as follows by its individual identifier (Z2 to
Z5):

Intake pipes over several cabinets
Installation of device and the intake pipes for the monitoring of several cabinets
If more than two cabinets are monitored, the upstream device should be placed in a middle
cabinet, so that 2 as identical as possible and flow-technically favorable pipe lines are
formed.
Note!
If more several cabinets are monitored, which are hermetically locked each against
the other, an equalization of pressure is to be installed by means of an air flow recirculation.
For the pressure balance by means of
an air flow re-circulation a further pipe
system is to be installed. This pipe
system (blue coloured in opposite
sketch) is led in each cabinet with Tfittings. The ends of pipe of the air flow
re-circulation remain open in each
cabinet, so that the air pressure
balances itself
In the opposite sketch it is assumed that
the cabinets are not locked hermetically
against each other.
The devices may be installed only so far
away from each other that the length of
the intake pipes amounts to max. 20 m.
A potential equalization has to be
carried out over the grounding of the
device.
