To call personnel to the place where the call was triggered from

To search for personnel or groups of people

To forward information (e.g. from medical devices)

A call system is a visual/acoustic system that can be used:

What are call systems ?


DIN 0834 areas of application:●Old people's homes●Assisted living●Medical practices●Dialysis stations●Hospitals●Adult day-care centres

Patient call system for hospitals and nursing facilities


Call systems -> DKE subcommittee "General signalling systems and signalling devices" is responsible

Responsible for the DIN VDE 0834 standard "Light call systems; installing and operating systems in hospitals, nursing homes and

penal institutions"

Electrical engineering standards are created by the DKE (German Electrical Engineering Commission) -> Subsidiary of the VDE and the German Standards Committee

Standards and regulations for call systems


Systems for domestic use (home emergency call systems) are subject to the EN 50134 standard

Emergency call systems used for ensuring the safety of persons living at home

Excepted from the DIN VDE 0834 standard


Presence buttons with acoustic signallers (call forwarding) must be installed in rooms where nursing staff are usually to be found

Triggering of emergency calls when present with appropriate signalling

Visual display of triggered call -> reassurance light

Call button clearly marked and visible in the darkEvery bed has a call button -> easily reachable

A room signal light (RSL) must be installed outside every room with a red + green display and an optional white display (WC call)

Key features of the DIN VDE 0834 standard


Nursing staff must receive information within 5 s

Non-visible rooms (wet rooms) require a separate cancel button

Text displays must be recognisable from 20 m at 500 lux

A call must be displayed on the RSL within 1 second

The light must be clearly visible at 500 lux

No common covers for call / operating devices and high voltage devices

The presence button is used for cancelling the call



System voltage may only be used for the intended purpose Exception:

An impulse relay switch for a reading lamp or similar.

This must be permanently connected and have its own overvoltage protection.

Non-intercom systems -> no remote cancel -

but the acoustic call forwarding may be cancelled.

For call systems with intercoms, calls may be remotely cancelled

whenvoice communication has occurred

Transmission paths for other systems may not be used for call systems (separate cable)

System voltage less than 30 V AC or 60 V DC



All protective grounds connected to the call system must be connected to the same main potential equalisation point. If this is not possible then the individual areas must be galvanically isolated.

Cables connecting buildings must be equipped with overvoltage protection at the exit points

Call systems require emergency power no later than 15 s after the normal power has failed. Must be maintained for 1 h / calls must

be

stored for at least 30 s after a power failure.

System voltage less than 30 V AC or 60 V DC

Station bus


All the room modules for the station must be connected to the station bus. Stub cables are to be avoided. The station bus should be laid as a ring cable. ELSO GmbH recommends closing the ring. This results in double data reliability. Please make absolutely sure that the conductors ("a"; "b"; "+24VDC" and "GND") are not swapped. The station bus cable (subsequently referred to as SYK=system cable) must be of type: Lapp Kabel UNITRONIC Bus Combi EIB 2x2x0.8 + 3x1.5, or equivalent quality. The shield must be connected to each of the GND terminals. To avoid short-circuits in the device, the shield must be insulated.The data cable must not exceed a length of 500m.

A distribution box is necessary when using an SYK system cable. This is provided with delivery (-> Terminals with connection cable and fuse -

> slow blow fuse 250V / 2.5A ).The power supply cables of the SYK are connected to the +24V and

GND distribution box terminals. The red output cable of the distribution box is connected to +24V, the blue to GND.The supplied system cable 2x2x0.8 must be used for connecting to

the station bus.

A button address must never be assigned twice, i.e. the address "Room Call 2" must only exist once per room. This also applies to all other cases. Failure to do this will result in system malfunctions.However, a single bed can be assigned a maximum of 3 buttons with different sub-addresses. A call button with system socket provides two sub-addresses "-1" and "-2" (for example: "Bed call 1-1" and "Bed call 1-2"). Note: The call button also provides the sub-address "-3" (for example: "Bed call 1-3"). The pull button and pneumatic button also provide the sub-address "-1" (for example: "Bed call 1-1")

Setting for jumper X4

Left "ON": (factory setting) 24 Volt supply switched on

Right "OFF": 24 Volt supply for the room module and the entire room installation is switched off. This should always be switched over for servicing / de-installation purposes!

Settings for jumpers X5a and X5b

Down: Factory setting: Both jumpers must connect the terminals BL-B/d and R-B/t in order to implement connection of devicesvia the room bus.

Up: Thus jumper setting must not be selected ->

Malfunction!
