Introduction

1.3 Area of application
The Gira emergency set is used to signal emergency situations and for alarming personnel.
Signalling of an emergency situation is via a red signal light in the call module as well as
acoustically via a buzzer (activated optionally) in the call module.
An additional call button and duty room unit can be optionally connected to the emergency
set as a reception unit via which a call can be signalled visually and acoustically, e.g. in
another room.
The Gira emergency set is suited to all areas of application in which the installation of a call
system according to DIN VDE 0834 is not expressly required, but where use of a call system
is still expedient and is also thoroughly recommended due to high risk factors. Thus
installation is possible in locations such as public outdoor facilities (e.g. toilet rooms in public
baths), in public buildings such as administrative authorities, museums, department stores
and also at places of work with especially high risk potential.
The range of application therefore covers for example all rooms in which persons who are
alone (without visual or acoustic contact to their surroundings) may become subject to an
emergency situation.
Gira assumes neither legal responsibility nor provides a guarantee for errors and damage of
any kind as a result of improper use and/or unprofessional installation of the emergency set.
1.4 Interfaces and connection options
The emergency set features the following interfaces and connection options:
– Relay contact (zero-voltage connection) in the call module, for connection of an
external device (e.g. Gira TeleCoppler, order number 0363 00). See also "Call
module" on page 23.
Consult the operating instructions of the external device!

2. Installation and start-up
Installation of the Gira nurse call system is to be carried out by a skilled electrician only. He
must pay attention to the applicable requirements of DIN VDE 0834, DIN VDE 0100 and
further standards as well as statutory regulations.
All emergency set devices are installed in flush-mounted boxes.
Wiring may be carried out with cable material such as J-Y(St)Y, 4 x 2 x 0.6 mm. When
selecting cable material, further regulations and directives (e.g. freedom from halogen)
must be observed.
2.1 Recommended installation heights for devices
Devices such as the call button or switch-off button should be mounted to a height of
0.7 m to 1.5 m. DIN 18024-2 (barrier-free construction) also stipulates that operating
elements for wheelchair patients should be mounted to a height of 0.85 m. With pull-
cord buttons in bathroom units, specific requirements specified by DIN 0100-710 must
be adhered to. Pull-cord buttons must be fitted at least 20 cm above the highest
possible position of the shower head. It must be possible for the pull cord to be reached
by persons lying on the floor.
2.2 Recommended installation height for the call module
The call module should be mounted to a height of 1.5 m to 2.2 m.
i
Note: reef knot on handle of pull-cord button.
The handle of the pull-cord button is to be secured with a reef knot on the pull cord.

2.3 Installation of power supply unit
Care must be taken that the 230 V~ cable remains separate from the 24 V cable during
installation.
We recommend: positioning the power supply unit to partition the cables.
Figure 2.1: Separation of the power supply areas with the power supply unit
Important! Ensure uninterruptible power supply!
It is recommended to use an uninterruptible power supply (UPS) in order to ensure
continued functionality of the emergency set in case of power failure.

2.4 Functional description
If a person in need of help pulls on the cord of the pull-cord button (optional: pressing the
red button on the call button), a call is triggered. The triggered call is signalled by a
reassurance light in the housing of the pull-cord button. Simultaneously the red signal light
of the call module located outside of the room signals that help is needed in the room.
The optional duty room unit can be installed for example at a central point e.g. in the
doorman's room. This visually signals the call to the personnel by lighting up of a call lamp
in the button of the unit and also acoustically with a buzzer tone. The call can be
acknowledged with the "buzzer OFF" button (yellow): the acoustic signal is suppressed for
approx. 20 seconds.
The switch-off button is located in the room where the call was triggered and is installed
adjacent to the door. A triggered call can be deactivated by the person hurrying to give help
pressing the green switch-off button.
Visual call signalling is with a flashing light.
The acoustic call signalling can be optionally connected directly in the call module via a
jumper on the call module (see "The jumpers of the devices in the emergency set" on
page 22).
The call module features a zero-voltage relay contact. This can be used for example for
connection of a Gira TeleCoppler (optional). See also "Call module" on page 23.
The call triggering components are monitored for wire fracture. In cases of wire fracture the
red signal light lights continuously. If the jumper is connected to the call module a
continuous acoustic signal is emitted with wire fracture.
Following power failure a triggered call is retained.
The maximum distance between call module and duty room unit (reception unit) is 500 m.
2.5 Wiring routing
With wiring routing the following factors are important, partly also specified by
DIN VDE 0834:
- Fireproof routing in escape routes.
- Safe electrical isolation from high voltage systems.
- Prevention of malfunctions by other systems.
- Safe wire connection.
Many federal states stipulate halogen-free installation material (including cabling and flush-
mounted boxes) for public buildings. This requirement is also applicable for use of
supplementary mounting aids such as clamps.
Gira emergency set devices are equipped with screw terminals.

2.6 Emergency set standard system
As standard, the call triggering components of the Gira emergency set are wired according
to the so-called idle current principle (series connection). Wiring of the call switch-off
components is carried out according to the working current principle (parallel connection).
2.6.1 Wiring of the call triggering components
The call triggering components, e.g. pull-cord buttons and call buttons are connected in
series (idle current principle). If the call system is in idle state, a low current flows (idle
current). When the corresponding button is pressed the flow of current is interrupted, thus
triggering the call.

2.6.2 Wiring of the call switch-off components
The call switch-off components, e.g. switch-off button, are connected in parallel (working
current principle). If a call was triggered in the call system, pressing of the switch-off button
for example closes the circuit again, thus switching off the call.

2.6.3 Wiring of the standard system
A WC suitable for the handicapped with pull-cord button and switch-off button can be
equipped with the standard variant of the Gira emergency set. A call triggered by the pull-
cord button is visually signalled by the red signal light of the call module outside, adjacent
to the door of the WC. The call is switched off with the switch-off button in the WC area next
to the door when the danger situation has been dealt with.
Components used:
– Call module (RM)
– Pull-cord button (ZT)
– Switch-off button (AT)
– Power supply unit, flush-mounted, 250 mA (NNRS)
Figure 2.4: Example for emergency set in a WC suitable for the handicapped
A 4 x 2 x 0.6 mm cable must be laid for each emergency set component.
This method of cable routing guarantees sufficient numbers of wires even after
modifications to the system have been carried out.
We recommend: call module and power supply unit installation in a deep flush-mounted
box.
