•  Continuous circuit (AUX power 1): 24 VDC nominal at 500 mA (up to 1 Amp of alarm 
current is available on AUX 1 if you reduce the total available control panel NACs alarm 
current by the total amount of AUX 1 + AUX 2 alarm current over 500 mA). Use this circuit 
to supply 24 VDC continuous power. A SMK module is required when using the UM or 
MAB module to support two-wire smoke detectors. 
•  Resettable circuit (AUX power 2): 24 VDC nominal at 500 mA (standby and alarm). Use 
this circuit to provide 24 VDC resettable power. You can configure AUX power 2 as a 
continuous circuit if you do not need a resettable circuit. 
•  Special application circuits  
•  Ground fault impedance: 0 to 5 kΩ 
•  Supervised and power-limited
