IFC-3030 Installation Manual — P/N 52024:C 08/05/2005 63
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 JCPU-3030ND (0.3
amps for JCPU-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.
A.4 Wire Requirements
Each type of circuit within the Fire Alarm Control System requires use of a specific wire type to
ensure proper circuit operation. The wire gauge of a particular circuit depends on the length of that
circuit and the current traveling through it. Use Table A.1 on page 64 to determine the specific
wiring requirements for each circuit.
Compliance with the Federal Communications Commission (FCC) and Canadian Department of
Communication regulations on electrical energy radiation requires the following: Use twisted-pair
