Operation Instruction VARIODYN® D1 Comprio
1 General / Application
Thank you very much for choosing VARIODYN® D1.
An emergency audio warning system or a voice alarm system as defined by the standards DIN VDE 0833-4 and
TRVB S 158 must consist of components that satisfy the standards of the series DIN EN 54. It must be ensured
that these components interact together in a manner appropriate to the function.
Devices for use in demanding ambient conditions, such as cold stores, galvanising plants or corrosive
atmospheres, must be suitable for this particular application or must be adapted using suitable protective
measures.
Designation of the system depending on the region of use
Depending on the location of use (country, applicable standard), the system is designated as either an
emergency audio warning system (AWS) or a voice alarm system (VAS).
In the interests of readability, only the term “voice alarm system” is used in the following chapters.
D
A
A voice alarm system can be used for issuing alarms anywhere that hazards to people can be expected. Voice
alarms are particularly effective in buildings and rooms frequented by visitors or other people who are not
trained how to act in an emergency or where visual signal devices cannot always be clearly recognised. An
especially high level of risk exists in the case of people who are dependent on external help in an emergency,
such when evacuation of the building is necessary. This may include people who are ill, the elderly and children.
The voice alarm system is mainly used in combination with a fire alarm control panel for emitting alarms. In
practice, the voice alarm system is also used for tasks outside of this area of application. Typical examples of
this include spoken messages such as advertising or calling people in airports, announcements at train stations
or playing background music.
Different requirements are placed on the voice alarm system depending on this combined use as an alarm and
as a general public address system. For example, external loudspeakers which can generate a high volume
level are required for voice alarms. At the same time, however, it should be possible to transmit a high-quality
music signal in other areas and ideally also to control the volume for individual areas. The requirements for the
areas of safety, comfort and flexibility demand a high level of specialised skill for the planning and
implementation of a system as well as very good knowledge of individual product components.
The VARIODYN
components according to the specific building requirements. This means that special solutions can be
implemented economically and effectively for buildings of different sizes and for various alarm tasks.

2 Display and Operating Elements
2.1 VARIODYN
The functions of the VARIODYN® D1 individual components are collected together in the compact control unit. A
control unit consists of a digital output module (DOM), a universal interface module (UIM) with a reduced
number of control contacts, a view control module (VCM) and an integrated voice input station with 12
programmable buttons.
The final amplifier as well as the loudspeaker, for example, is connected to the control unit. A control unit offers
interfaces to all input/output modules and also manages and monitors the loudspeaker circuits. Other
components of the VARIODYN
The standards-compliant display of collective messages as well as operation and monitoring take place using
the four integrated buttons / LEDs. The control unit is configured via the programming and service software
Designer D1.

• Upon acknowledging of the buzzer, only the acoustic warning signal is temporarily deactivated.
• Resetting of the alarm and fault messages is only possible after correcting of the fault cause and
may only be performed by a qualified technician.
Pressing the button repeatedly will run through the individual listening points. The
current listening point is indicated by the green flashing LED of the corresponding

3 Maintenance and Installation
Operation and maintenance of hazard warning systems (HWS)
Requirements as per VdS guidelines and VDE 0833-1 and 2:
The operator of the HWS must have received proper training or must have the work performed by someone who
has received proper training. The operator or the person he/she commissions must take responsibility for
ensuring that inspections are carried out when there are signs that the constant readiness of the system may
have been impaired, in event of irregularities in the functioning of the system and in cases of alterations (e.g. in
the use or design of the room) that may influence the monitoring tasks of the HWS. All necessary maintenance
and alteration work on the HWS must be carried out immediately by the operator or the trained person who
he/she commissions. HWS must be regularly serviced by an electrician. If there are faults, the HWS must be
immediately inspected and corrected by an electrician.
Inspections
Perform inspections according to VDE 0833-1 at least four times per year at roughly equal intervals.
Repairs
Must be carried out immediately if it is confirmed during an inspection that there unauthorised deviations from
the nominal conditions of the HWS.
Maintenance work
Perform maintenance work according to the manufacturer instructions, however no less than once per year.
This includes, for example: maintenance of system parts, replacing elements with limited service life (e.g. light
bulbs), alignment, setting and adjusting of components and devices. The specifically required annual
maintenance work may be performed along with the quarterly inspections.
In addition, the HWS must be inspected every five years to ensure that it fulfils all requirements of this
standard..
Regular tests
In principle, the statutory standards, regulations and local requirements apply for the maintenance of the voice
alarm system. However, these may be restricted by the manufacturer's specifications. For example, the
manufacturer may stipulate that the maintenance intervals or replacement cycles of the devices must be shorter
than required by law.
•Regular tests must be carried out to ensure that there is not and will not be any restriction on the emission
of sound from the loudspeakers or on their function
•Regular tests must be carried out to check whether rooms excluded from the public address system in the
planning documents now need to be included in the public address system.
•Regular tests must be carried out to ensure that when the voice alarm system or even one of the individual
parts of the voice alarm system is switched off or malfunctions there is a suitable backup measure available
(e.g. security personnel with megaphones etc.).
•Loudspeaker testing must be carried out at least once per year using suitable audio tests. If there is any
doubt, a measurement must be carried out to prove the speech comprehensibility.
• In accordance with EN 60849, a maintenance contract must be concluded.
• Maintenance work must be carried out in accordance with DIN VDE 0833-4 or TRVB S 158.
• All events such as fault / replacement / maintenance / calibration of the VAS must be documented
in a log book (Part No. 798671).
•The operating log must be stored near the system (or on the operator's premises).
Important information
After an interruption of the power supply due to maintenance or if call stations are relocated during
maintenance, the proper functioning of each individual call station must be checked.
The fire department / evacuation call stations in particular must be checked by executing relevant
functions as well as performing a “test announcement”.
