CLAS for hospitals

Seniorenheim alarm

CLAS can be used in hospitals and health resorts by nursing staff to quickly locate furniture and medical equipment, but also by patients to trigger mobile emergency calls.

The battery life of the transmitters used is decisive for the ease of maintenance of a localisation solution.
CoSi electronics uses the latest radio technology combined with intelligent sensor technology in the FuFi-bark-ISMs provided for this purpose. This allows the CoSi transmitters to work for up to 7 years with the same battery.

Whether CLAS may only be used as a supplement to an installed nurse call system/light call system for patient emergency alerting, or whether it can also be used as the sole emergency call system in the hospital depends on the different legal requirements in the respective countries of use.

In Germany, the use of a call system is mandatory for hospitals according to the German standard VDE0834.
CLAS exceeds most of the safety requirements of the currently valid version of this standard. However, this is currently being revised. Depending on the future requirements of the successor version for a call system in hospitals, CoSi electronics is also considering official certification of CLAS according to VDE0834 in the medium term.

As CLAS was designed as a radio solution, only a 24V power supply is required for the radio receivers to be installed. There are no costs for laying signal lines. This means that the solution can be installed, parameterised and commissioned very quickly and cost-effectively in both new buildings and existing hospitals/spa facilities.

Should a receiver fail, a corresponding fault message is immediately sent. Due to the redundant design of the CLAS receiver technology, this does not lead to any restrictions in the emergency alarm system. A trained building technician can replace the defective unit quickly and easily.

Optionally, wired triggering components, such as pear pushbuttons and pullcords, wired modules for nurse identification, alarm escalation and alarm resetting, as well as corridor lamps for visual alarm signalling, can be connected to the system on request.

A CLAS solution for hospitals/spa facilities consists of the following modules:

  • CoSi Linux server with CLAS server software.
  • Ideally, but not absolutely necessary, a usable WLAN network in the hospital.
  • A MESH gateway terminal for setting up redundant alarm routes
  • Ideally, but not absolutely necessary, an SR-ISM-WLAN radio receiver/radio gateway in each room
  • One FuFi-bark-ISM for each medical device and furniture item to be located
  • Mobile emergency hand-held transmitter, e.g. FuFi-smart-ISM, for issuing to patients
  • Optional radio-based manual release devices, such as the FuFi-bath-ISM or the FuFi-pull-ISM
  • Optional radio-based fire detectors, such as the FuFi-smoke-ISM or the FuFithermo-ISM, as a supplement to a fire alarm system
  • Optional automatic detectors such as the Fufi-motion-ISM or the FuFi-motion-ISM-S
  • The optional connection of contact inputs via a FuFi-wire-ISM or a FuFi-MConact-ISM

For a desired connection of wired modules, IP-dialler-solo, IP-dialler-solo-H or IP-dialler-western are required.

Each of these IP-diallers can be optionally extended by a SeCom interface. An optional SeCom-4x multiplexer can be used to connect 4 additional SeCom interfaces.

Finally, up to 5 different SeCom triggering components, an RFID reset unit and a corridor lamp can be operated at each SeCom interface.

CLAS supports several options for forwarding alarms to the responsible nursing staff. CoSi electronics recommends the use of Android caregiver smartphones for this purpose. CLAS then alerts on the CLAS app installed there. Alternatively, Android tablets can also be used.

In addition to the use of the graphical alerting interface, close-range identification of the mobile emergency call transmitter and thus also of the person in need of help is also possible via the Android devices. The CLAS app then automatically reports to the CLAS server which carer is currently looking after which person in need of help, at which location in the care facility.

As an alternative to using the CLAS caregiver app, it is also possible to forward the alarms to external systems. Mobile DECT telephones, for example, can then also be used to receive alarms.
