Section 5 - Alarms
5.1 Alarms
The Steri-Cult incubator alarm system is shown in the table below. When an alarm is active, the message appears in the LED
message center. Pressing Silence disables the audible alarm for the ringback period. However, the visual alarm continues until the
incubator returns to a normal condition. The alarms are momentary alarms only. When an alarm condition occurs and then returns to
normal, the incubator automatically clears the alarm condition and the message center.

- All alarm delays and ringback times are ±30 seconds -
When multiple alarm conditions occur, active messages are displayed in the message center one at a time, updating at 5 second
intervals. Pressing Silence during multiple alarms causes all active alarms to be silenced and to ring back in 15 minutes.
The temperature alarms are disabled when the temperature setpoint is 10°C. The CO2 alarms are disabled when the CO2 set point
is 0.0%. RH alarms are disabled when the setpoint is 0% RH.
