Prince of Wales Hospital prepares to accept the handover of the new Level 6 surgical inpatient units, the Acute Services Building Redevelopment Change and Commissioning team, along with staff from Engineering, Digital Health and Security, have been involved in a range of system testing activities. Some of the tested systems included nurse calls, duress alarms, lockdown functions, lighting and power, and pneumatic tubes. One of the tests involved turning off the non-essential power on Level 6 and ensuring that essential services remained operational. Essential services include exit signs, swipe card access, emergency lighting, communications and essential medical equipment such as gas outlets with oxygen meters and flow readers.
