| Expected Outcome |
- Durable tactile feel wireless nurse call unit completed with a nurse call push button, an emergency call pull button, a reset button and a built-in wireless transceiver based on an open wireless communication protocol, complying with Health Technical Memorandum (HTM) 08-03 or Underwriters Laboratories (UL) 1069.
- Central display console which connects with system components through wireless data communication network is capable of displaying the real-time status of the nurse call units and the fault alarm in a Graphical User Interface (GUI) and logging key performance data for effective operation and maintenance management at the nurse station.
- System should incorporate the following functions:
- To attain an average system availability level of 99.5%, the miss call rate due to radio frequency interference and the call response time can be minimized by setting a time limit for call re-transmission, typically, in unit of seconds;
- To set a processing time limit of 5 minutes for the system–initiated fault diagnostic routine for facilitating early automatic fault detection of system wireless components and early notification to maintenance agent. A typical setting of the transmission interval of the health-check signal for fault detection of wireless nurse call units and wireless hubs is 1 minute;
- Automatic fault detection includes but not limited to ‘low battery’, ‘out-of-range’ and ‘out-of-battery’ of wireless nurse call units;
- Reassurance light and sounder to indicate the activation of wireless nurse call units, complying to HTM 08-03;
- Wireless nurse call units can be easily taken down from a lockable bracket for patients’ remote use;
- Central display consoles can extend to wireless phones and pagers for maximum mobility (optional);
- Extra provision of remote nurse call button or wrist/ neck pendant which allow patients to make a call from any locations in the concerned wards (optional).
