The operating mode is selected via the switches under the unit’s cover:
1. 24V DC power monitoring mode – Alarm triggered when 24V DC is lost at input X2.
2. 230V AC power monitoring mode – Alarm triggered when 230V AC is lost at input X2.
3. Normally Open (NO) dry contact input mode – Alarm triggered when a short circuit occurs between the "+" and "-" terminals at input X2.
4. Normally Closed (NC) dry contact input mode – Alarm triggered when an open circuit occurs between the "+" and "-" terminals at input X2.
