Appendix A: Electrical Specifications
A.1 Operating Power
DC Power The control panel requires connection to NPS-5CHS or NPS-11CHS, which is a
27.3 V DC regulated, power-limited power supply, that can supply 0.1 amps continuous for the
CPU without the display (0.3 amps for CPU with the display).
A.2 SLC Loops
Listed below are specifications for a Signalling Line Circuit loop. Refer to the SLC Wiring Manual
for more detailed specifications and specific device listings:
A.3 Notification Appliance Circuits
The power supply provides Notification Appliance Circuits. The maximum current rating for each
NAC output is 1.0 A. Refer to the Device Compatibility Document for compatible devices and
notification appliances.
A.4 Networks
A.5 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 the table below to determine the specific wiring
requirements for each circuit.
Use twisted-pair shielded wire for any non-SLC-loop wiring entering or exiting the cabinet that is
not enclosed in conduit. Use twisted-pair unshielded wiring for SLC-loop wiring.
Item Value
Voltage 24 V DC nominal, 27.6 V DC maximum
Maximum length The maximum wiring distance of an SLC using 12 AWG (3.25 mm
2
) twisted-
pair wire is 3810 m.
Note: Refer to Appendix A.5 “Wire Requirements” for limitations.
Maximum current 130 mA: LCM-320
100 mA: LEM-320
400 mA max*: Single SLC loop; for battery calculations use 200 mA
*Max short circuit; circuit will shut down until short circuit condition is corrected.
Maximum resistance 50 ohms (supervised and power-limited). For additional notes on SLC
resistance values, see Section 4.1 “Operational Checks”.
Network Card Communication Parameters
NCM-W Supports twisted-pair wire medium, data is regenerated at each node. 312.5K
baud transmission rate.
NCM-F Supports fibre-optic medium (62.5/125 or 50/125 micrometres – multimode).
Single mode available. 312.5K baud transmission rate. Data is regenerated at
each node.
HS-NCM High-speed data communications (12 Mb wire, 100 Mb MF/SF fibre). Multi-
mode fibre optic (MF), single-mode fibre optic (SF), wire (W), or a combination
of W/MF/SF communications path.
NOTE: If running an SLC in conduit with Notification Appliance Circuits, you can reduce
problems by exclusively using electronic sounders (such as the MA/SS-24 Series) instead of
more electronically noisy notification appliances (such as electromechanical bells or horns).
