Notes:
1.
For power supply calculations, refer to Appendix A.
2.
Total current for nonresettable power, 4-wire smoke detector power and two Notification Appliance Circuits
must not exceed 5.6 amps
. Total external system current in excess of 3.6 amps requires the XRM-24 Trans-
former (XRM-24E for 220/240 VAC applications) and 12 Amp Hour or 17 Amp Hour batteries.
