[1] Enter 1 regardless of how many are installed. Only the first SIGA-UM or SIGA-MAB in the alarm state draws
current. The other ones do not because the system load sheds additional modules in alarm.
[2] If the panel AUX 1 is used to power an RZI16-2, the NAC alarm current must be reduced by the total AUX
alarm current amount over 500 mA.
[3] Total AUX alarm current =
1000 mA max for AUX 1*
1000 mA max for (AUX 1 + AUX 2)*
500 mA max for AUX 2
*You must reduce the total NAC alarm current by the total amount of AUX 1 + AUX 2 alarm current over
500 mA.
