For alarms a dedicated MBBI record is implemented with 2 states NO_ALARM and Alarmed. The state itself calculated using CalcOut record. The alarm would be triggered if:
If the channel is in enabled state and
{
If channel is in neither of the following states:
1. The channel is ramping up and
|v0set:fbk - v0set| < ε
2. The channel is on and
|v0set:fbk - vmon| < δ and
|v0set:fbk - v0set| < ε
}

The δ and ε are different parameters for CAEN HV, WIENER LV abd BIAS modules.
| CAEN HV | WIENER LV | WIENER BIAS | |
| δ | 2V | 0.1V | 0.5V |
| ε | 0.01V | 0.01V | 0.01V |
Calcout record is recalculated and alarm state changed subsequently if one of inputs are changed achieved using posted monitors on input channels.
