Appendix A Electrical Specifications Operating Power
62 NFS-3030 Installation PN 51330:C 10/28/2003
Appendix A Electrical Specifications
A.1 Operating Power
DC Power
The control panel requires connection to a +24 VDC regulated power supply, UL/ULC-listed for fire
protective service, that can supply 0.1 amps continuous for CPU-3030ND (0.3 amps for CPU-3030D).
For complete battery/current draw calculations, refer to the main power supply manual; if using an
auxiliary power supply, there may be additional calculations in that manual.
A.2 SLC Loops
Listed below are specifications for a Signaling Line Circuit loop:
A.3 Notification Appliance Circuits
Notification Appliance Circuits are provided by panel circuit modules and SLC loop devices. Non-
hazardous agent releasing devices may be connected on the SLC loop.
If using an auxiliary power supply, refer to that installation manual for product-specific specifications.
Refer to the Device Compatibility Document for compatible devices and notification appliances.
