1 Description of control unit
The FireSafe is a control unit intended for use (in combination with a GfA or Kostal electrical drive
that has a digital limit switch) on industrial doors that need to close in the event of an
emergency. When used in combination with an emergency power supply, the door will close
even if there is a power failure. The opening and closing movements in normal mode can be set
to deadman or automatic operation (impulse) via a menu. The buttons on the unit and the
external up-stop-down controls are used for operation. Operation is also possible using impulse
control. There is an input to turn the controls on or off.
The cover has an LED that lights up green in normal mode and red in the event of a fault, fire or
power failure. The cause of the red LED is then shown on the control PC board display.
The control unit can be fitted with an emergency power supply so that the door can still close
even if there is a power failure. The door will close if there is a fire or if the batteries of the
emergency power supply are nearly flat. A test function allows you to close the door using the
emergency power supply to check that it is working properly. An escape pushbutton can be used
to open the door in an emergency if there is still mains power and the emergency power supply
batteries have sufficient capacity. You can also specify that the door can still be opened with the
open button, and that when it is released the door immediately closes again. Here too, this is
only possible if there is still a mains power supply and the batteries have sufficient capacity.
In normal mode, the door will descend until the "closed" limit switch has been reached. You can
specify, for the event of a fire or when the battery voltage is low, whether the door should stop
when the normal "closed" limit switch is reached or when the "overclose" limit switch is reached.
The "overclose" limit switch position is set via the menu. It should be set further on than the
"closed" limit switch so that the door closes further than in normal mode.
If the door is moving, a potential-free make-and-break contact to which a siren or other alarm
signal can be connected, is switched. The contact will also be switched if you specify in the menu
settings that a pre-warning should be issued before the door closes. This stops when the door
stops moving.
A potential-free make-and-break contact, to which a siren or other alarm signal can also be
connected, will also switch in the event of a fire or if the battery for the emergency power supply
is nearly flat.
There are also a number of outputs with the same common that can be used to send various
messages.
There is the option to connect a detection device to detect persons/objects under the door. This
could be a detection device operated by air pressure contact (in combination with 1.2KΩ), an
8.2KΩsafety edge or opto sensors. If you choose automatic closing in normal mode, the door will
stop and open fully or simply stop if the detection device is triggered.
The detection device can remain enabled or be turned off in the event of a fire. The delay time
until the door continues descending after the detection device is triggered can be specified in the
menu. For the event that there is still a power supply, you can also specify that the door should
open fully and then close again when the detection device is triggered in a fire or when the
battery capacity is low.

For the event that the safety mechanism is triggered when the closed pre-limit switch is reached,
you can choose in the menu whether it should then simply stop there, or the detection device
should be turned off and the movement continued until the "closed" limit switch is reached.
Photocell safety devices only work in normal mode and will cause the door to stop if the beam is
broken. If you release the "close" button and then press it again, the door will continue closing.
The photocell will be turned off in the event of a fire.
The service cycle counter can be enabled in the menu. When it is enabled and the set number of
cycles is reached, the LED will light up red and green alternately. A message will appear on the
display.
If the emergency/fire alarm contact is interrupted or if the batteries are nearly flat (and
the close option has been selected for this event), the door will close automatically and
the safety device may not be enabled!
The required mains supply is: 1N~230V AC +/- 10% (phase + neutral + earth)

3 Installation
For reliable, professional installation of this control unit, check and implement the points below:
üThe control unit must be installed in a robust housing that fulfils the requirements with
respect to the location in which it will be sited.
üThe cable grommets may need to be replaced to meet the required IP value. Additional
seals may be required.
üPVC insulated cabling may only be used in indoor spaces.
üThe power supply phase (1N~230V AC-50Hz, +/-10%) must have a fuse to prevent short
circuiting and overload.
üIf using a power supply cable with a 3-pin 16A CEE plug (phase, neutral & earth), a 16A
wall socket should be installed in the immediate vicinity of the control unit with a fuse
that meets the applicable standards/guidelines. After installing the control unit and
supply cable plus the wall socket, check that the screw connections have been properly
tightened and that everything has been correctly connected.
üIf a supply cable is connected to the system, the following applies: Connect up the control
unit using a fixed supply cable and fit a fuse as indicated earlier. A multi-pin switch must
be fitted in the immediate vicinity of the control unit to interrupt the power supply, all
pins of which should be interrupted when it is switched off. Note: the switch used should
have a contact opening that meets overvoltage category III for total isolation.
üAn on-site risk assessment must be carried out on the entire system by the installer.
Check as part of this process that the door or gate is properly secured and does not pose
an entrapment risk for persons or objects.
üThe system must, as a minimum, fulfil the requirements of European and locally
applicable legislation and standards. Under European legislation, automatic doors or
gates must satisfy the requirements of the Machinery Directive 2006/42/EC and in
particular the following standards: EN 12445; EN 12453; EN 12635 and EN 13241-1, that
permit a declaration of conformity.
üMeasures must be put in place to prevent the door or gate limit switch being passed, e.g.
safety limit switches, mechanical stops or other safety systems.
üCheck the technical specifications of any external components used, such as: photocells,
traffic lights or induction loop detectors. These may not exceed the max. permissible load
on the control unit.

5 Commissioning
After switching on the mains power supply, the door can be operated in deadman mode* using
the pushbutton on the PC board. The direction of rotation should coincide with the buttons. If
this is not the case, disconnect the mains power supply and swap the two phases (U and V) on
the frequency control output. After you have checked the direction of rotation, the end positions
can be set. To do so, the control first needs to set its direction. For this purpose, run the control
in any direction for around 4 seconds.
After setting the end positions, the control can be configured as required in the menu. The door
mode (0.1) is an important parameter for configuration. Set the parameter to 1 for deadman
operation in both directions or set it to 2 for impulse-controlled opening and deadman closing or
to 3 for impulse-controlled opening and closing.

The door or gate can now be operated in deadman mode*. You can make fine adjustments and it
is easy to change the end position settings later using the menu (1.1 to 1.9).
* Deadman operation: The door or gate will move for as long as the arrow button is held down
Automatic or deadman mode
When the control unit is set to the factory settings, the door will open and close in deadman
mode.
If required, you can set the door to open automatically by setting parameter 0.1 to 2 in the
menu. To specify automatic opening and closing, set parameter 0.1 to 3.
Safety devices
There is the option to connect a detection device to the control unit. This could take the form of
opto sensors, an air pressure contact (in combination with 1.2KΩ) or an 8.2KΩelectrical safety
edge. The detection device is connected to X4. Use parameter 0.2 to choose whether it should be
detected automatically or whether to set up the connected safety device permanently. If you
choose "automatic detection", the safety device must be present when the control unit is started
up, and must not be interrupted or activated. The safety device will then only be detected on
starting up.
If no safety device is detected when starting up, fault message 2.0 will appear on the
display. If deadman closing has been chosen in normal mode, fault message 2.0 will
appear once. If automatic closing has been chosen, it will be shown repeatedly.
Parameter 0.3 is used to specify the function of the detection device in normal mode. In the case
of the factory settings, the door will stop and then open fully. Option 2 allows you to choose just
to stop the door if the detection device is triggered. A new command then has to be given for the
door to continue moving.
Parameter 0.4 allows you to specify the function of the detection device when closing in a fire, if
you have chosen to close when the emergency power supply battery voltage is low (parameter
3.7 set to 2). In the factory setting, the detection device is disabled. With option 2, the door stops
lowering and waits for the time set in parameter 0.5 and then continues closing. With option 3,
the door will open fully, if there is still mains power, wait for the time set in parameter 0.5 and
then close again. If there is no mains power supply, the door will just stop and continue closing
after the time set in parameter 0.5.
Parameter 3.6 allows you to choose to disable the detection device in the event of a fire if it is
not present or is interrupted when the fire alarm contact input becomes active.
Parameter 3.5 allows you to choose to restrict the number of times the detection device stops
the door. If you opt for this, you can choose using parameter 1.9 whether the detection device is
to be ignored if the maximum number of attempts has been reached (i.e. continue closing
without the detection device), or that the door should re-open after two seconds and then stop.
As well as the detection device, there is also the option to connect a photocell. This only works in
normal mode if you have chosen automatic closing. In this case, the door will stop if the
detection device is activated and then open fully.
The photocell is turned off in the event of a fire.

Impulse function
The control unit has an impulse input. If one direction is deadman, the impulse should be
retained in that direction. If it is released the drive will stop. If it is then pressed again, the other
direction will become active.
If automatic opening has been chosen, the door will continue to run according to the factory
settings until it reaches the open limit switch and can only then be lowered back down by the
impulse input. By changing parameter 2.2 to setting 2, the door can also be stopped during
opening by activating the impulse input once again. And, if the impulse input is activated again,
the door will descend in deadman mode for as long as the impulse input remains active.
Fire alarm function
If the fire alarm contact is activated, the door will close. In the standard factory setting, the door
lowers until it reaches the closed limit switch. If the door needs to descend further than the
closed limit switch, the optional "overclose" limit switch can be used. For this purpose, parameter
3.1 should be set to 2.
The normal open button can be turned on or off using parameter 3.3 if the fire alarm function is
enabled. If it is active, the door will open when the deadman is pressed and immediately close
again when it is released.
The fire alarm function can be extended after the fire alarm contact input has closed again. This
can be set from 0 to 240 seconds using parameter 3.4.
An input is also available to connect an escape pushbutton. When this button is pressed, the door
will open. Once the delay time –which can be set from 1 to 240 seconds using parameter 3.2 –
has expired, it will then close again. The button can be pressed again during the delay time to
close the door immediately.
NOTE: The door cannot be opened if there is no mains power!
You can choose, for the event of opening the door using the escape pushbutton or normal open
button in a fire, whether it should open fully or to a set mid-position. This position can be set in
parameter 1.7 and activated using parameter 1.6. It can only be activated if a position has been
set for parameter 1.7.
Test function and power failure
If the test function is active, a message will appear on the display and the red LED will light up. In
the event of a power failure, the red LED will also light up if there is an emergency power supply.
The power supply will switch over to emergency power and it will only be possible to close and
not open the door.
The test function is intended to check whether the door still closes on the emergency power
supply.
Battery for emergency power supply low
If the battery for the emergency power supply is too low, this will be communicated to the
control unit by the UPS RS232 connection. A message will then appear on the display and the red
LED on the control unit will light up. In the case of the standard factory settings, the door will
then close. If this is not desirable, it can be disabled using parameter 3.7.

Messages
There is a potential-free make-and-break contact on the control unit to which a siren or warning
light can be connected. This contact will switch when the door is moving.
There is another potential-free make-and-break contact, alarm, that switches when the fire alarm
input is active or if you have set the door to close when the emergency power supply battery
voltage is low.
There are 8 messages that have the same common, all designed as potential-free N.O./make
contacts. The messages are as follows:
-"Open" limit switch reached
-"Closed" limit switch reached
-"Overclose" limit switch reached
-Motor safety chain interrupted
-Test function active
-Detection device activated/faulty, can be set using parameter 2.3 or message output only
from the detection device or only from the photocell or both.
-Emergency power supply battery low
-No mains power (only works if there is an emergency power supply)
Service cycle counter
The service cycle counter can be activated in the menu using parameter 8.7. Parameter 8.5
allows you to set the number of door openings (per 1,000) before a service alert is output. When
the counter reaches zero, the LED on the cover flashes red and green alternately (if no fault
message is active) and the message C.S. will appear on the display.
