19.7 Solution Temperature Protective System
Overheated solution is prevented from reaching the patient by the solution
temperature protective system that uses a microprocessor, temperature sensor,
and cutoff switch that are independent of the temperature control system. The
protective system temperature sensing is accurate to ±2°C. The HomeChoice/
HomeChoice PRO APD System sounds a system alarm within 5 seconds of sensing
an overheated condition.
19.8 Audible Alarm Silence Period
If the user presses the STOP button to silence an alarm and does not take action to
clear the alarm, the HomeChoice/HomeChoice PRO APD System will reactivate the
alarm in 30 minutes.
19.9 Range of Sound Pressure Levels
The HomeChoice/HomeChoice PRO APD System audible alarm can be set to
produce sound pressure levels within the range of 65 dBA to 75 dBA at 1 meter.
System alarms are always at maximum volume.
19.10 Maximum Pressures Used to Transfer
Solution To and From the Patient
The HomeChoice/HomeChoice PRO APD System limits the pressure used to pump
the solution to and from the patient to a maximum positive pressure of +10 kPa
(+75 mmHg) (+1.5 psig) and a maximum negative pressure of –10 kPa
(–75 mmHg) (–1.5 psig).
