Short description
In accordance with DIN VDE 0834, the emergency system set is meant to be used in
bathrooms for people with disabilities. The DIN VDE 0834 must be considered during
installation and operation of the emergency system.
The set is comprised of:
•Emergency signal NRS .. 0834 RM ..
•Pull cord push-button NRS .. 0834 ZT ..
•Reset button NRS .. 0834 AT ..
•Power supply NRS .. 0834 NT ..
Only included in the emergency system set with UPS (NRS .. 0834-2 ..):
•UPS module NRS .. 0834 USV ..
Available separately:
•Service unit NRS .. 0834 DZE ..
•Call button NRS .. 0834 RT ..
•Service terminal NRS DZT 20 WW
•Surface-mounted housing for service terminal NRS DZT AP WW
•Deflexion pulley set NRS ULR 0834
Spare parts:
•Accumulator for UPS module NRS AKKU 130
•Pull cord ZS-34 KO5S
Functional description
When an emergency call is triggered with the pull cord, the red light on the push-button
confirms the successful call. The emergency call is indicated visually and acoustically by
the emergency signal. In stand-by mode, a light makes it easier to find the pull cord push-
button.
For other use cases, the visual and acoustic call can be transformed into a continuous
signal, for example, using a jumper. It is also possible to disable the acoustic call.
The unmonitored call can be sent from the emergency signal via a floating contact.
Pressing the reset button stops the emergency call.
If there is no superordinate emergency power supply, the UPS module must be used. The
UPS module ensures that the emergency call is triggered even in the event of power
failure. The accumulator included is easy to replace and available as a spare part. This
emergency power supply is monitored, every disruption is reported.
In battery mode, a short acoustic signal is sent to the emergency signal every 12 seconds.
Two short acoustic signals every 12 seconds are sent to the emergency signal to indicate
an accumulator disturbance.

The optional service unit serves to monitor call forwarding. The service unit would not only
indicate the emergency call acoustically but also visually. The call can be muted for
20 seconds or the additional call in the office disabled in absence.
The optional call button also includes lights to be found more easily and to confirm a
successful emergency call.
The service terminal shows unmonitored calls of several emergency calls centrally. It
reports the emergency calls acoustically and visually as plain text. Just as for the service
unit, call forwarding can de disabled on the service terminal in absence or interrupted for
20 seconds. Surface-mounted housing is optionally available.
In accordance with the Dutch standard NEN 1814, the length of the pull cord of the push-
button can be extended to 20 m using the deflexion pulley set. In Germany, this extension
is not obligatory but could be deemed necessary in certain cases. When the pull cord is
installed using the deflexion pulley set, even a person lying in the floor can send an
emergency call pulling at any point of the cord.
The emergency call system is ready for operation as soon as power is supplied. The UPS
module is only able to fully switch to emergency power supply if it was connected to supply
voltage for several hours. It could be up to 6 hours, depending on how long the
accumulator has been charged.

Safety instructions
!
Mounting, installation and commissioning is only permitted for electricians!
When working on systems supplied with AC 230 V, the safety requirements in accordance
with DIN VDE 0100 must be observed.
When installing the emergency system the general safety regulations for
telecommunication systems must be observed according to DIN VDE 0800:
•separate cable routing for mains voltage and extra-low voltage
•minimum distance of 10 cm when cables are routed jointly
•use of separators between high and extra low voltage power lines in cable duct used
jointly
•use of standard telecom cables, e.g. J-Y (St) Y 2x2x0.6
•only when power is off may all connection cables may be connected or disconnected
!
Measures for protection against lightning might be required.

11
Battery safety instructions
!
WARNING! Improper handling of batteries can result in explosion, fire or chemical burn
due to leakage.
•Do not heat or throw batteries into fire.
•Do not reverse polarity, short-circuit or recharge batteries.
•Do not deform or disassemble batteries.
•Replace batteries only with an identical or equivalent type.
•Remove empty batteries immediately and dispose of in an environmentally friendly
manner.

Details
•in flush-mounted box
•Installation note UPS module: installation into deep flush box
Installation height in accordance with DIN VDE 0834
(call systems in hospitals, nursing homes and similar facilities)
•Pull cord push-button min. installation height: at least 20 cm
above the shower head
•Operating devices 0.7 to 1.5 m above the floor
•Operating devices with text 1.5 to 1.7 m above the floor
•Devices with installation units 1.6 to 1.8 m above the floor
•Signal lights and text displays 1.5 to 2.2 m above the floor
DIN 18024-2 “Accessibility” also prescribes to install operational elements for wheelchair
users at a height of 0.85 m.

Installation
Installation above the supporting frame without claws
According to DIN VDE 0834 wearing components, i.e. batteries and accumulators, must
be replaced once a year.
Disconnect plug connector before changing the accumulator or decommissioning the
emergency system. This will prevent the accumulator from discharging and short-circuits
during the decommissioning of the accumulator.

Example wiring plan:
Emergency system set with additional emergency signal
RT, AT, 24 V and GND are connected in parallel. Typical use case for bathrooms which
are accessible from the corridor but with some distance to the main entrance. One
emergency signal reports from above the bathroom door, another from the main corridor.

16
Example wiring plan:
Emergency system set with additional call button
The additional call button is monitored. Here, the built-in status light gives feedback. For
the function of the status light to be in accordance with the norms, there must not be more
than 3 call or pull cord push-button.

17
Example wiring plan:
Emergency system set with additional pull cord push-button
An additional pull cord push-buttons are available for the emergency system set. For the
function of the status light to be in accordance with the norms, there must not be more
than 3 call or pull cord push-button.

18
Example wiring plan:
Emergency system set with additional reset button
Reset button are connected in parallel.
Example wiring plan:
Emergency system set with additional service unit
Up to 2 service units can be connected in parallel.

19
Example wiring plan: Call triggered by additional push-buttons
Triggering the call additional using another push-button (e.g. in the toilet support bracket)
is possible.
For this, RT must be connected via an NC contact.
The call is triggered at the interruption.

20
Example wiring plan: Unmonitored call
The emergency signals have a floating relay contact (DC 24 V, 1 A) which is suited for
unmonitored calls.
