GENERAL NOTES - Continued
l
All wiring must be in accordance with local codes.
l
All wiring should be in accordance with National Electric Code, Article 760.
l
A neatly wired system will help assure an accurate inspection of all connections and simplify troubleshooting.
GENERAL REQUIREMENTS FOR SYSTEM WIRING
These requirements are intended to aid the installer in making a safe and trouble-free installation, but they are not
intended to circumvent any pertaining and/or required codes, laws, regulations, etc.
Note: These wiring specifications are subject to local authority approval.
General Wiring Requirements For Fire Alarm Systems
1. All wires are to be copper conductors only.
2. All wiring, except incoming power and ground connecting wires, must be free from grounds or shorts and have
a resistance of one megohm, or higher, to earth.
3. Metallic conduit, metallic raceway, plastic pipe, or plastic raceways may be used.
If metallic conduit is used, the following must be observed: If the continuity of the metallic conduit is not
maintained, then a 12AWG (minimum) drain wire must be used between the break of metallic conduit. The drain
wire will be connected to the metallic conduit at both ends.
4. Only system wiring can be run in the same conduit, pipe raceway, or multiconductor cables.
5. Where system wires pass through floors or fire-rated walls, the installation shall be made to prevent the spread
of fire from floor to floor (i.e. patching of holes, fire stops, etc.).
6. All system wiring subject to physical damage shall be mechanically protected based on the environment the
cable is subjected to.
7. Each device - pull station, detector, horn, bell, etc. - must have its own enclosure such as a back box, outlet
box, etc.
8. A minimum of 6 inches of free conductor will be required in each electrical box to facilitate terminations. A 12-
inch service loop of cable is required for all continuous pulls through an electrical box.
9. Unused openings in electrical boxes shall be properly “blanked off” with suitable protection equivalent to the
wall thickness of the equipment. All splice boxes shall have a blank cover.
10. All wiring shall be terminated with U.L. listed devices (i.e. wire nuts, pressure connectors, etc.). Wiring
terminated with only electrical tape is not permitted. All splicing (free ends of conductors) shall be covered with
an insulation equivalent to that of the conductors.
SYSTEM WIRING SPECIFICATIONS
Incoming Power Wiring
Source - Life Safety Branch Circuit, or as required by local code.
Panel draws 2A maximum at 12OV, 60Hz via a fused disconnect or circuit breaker.
Wiring - Use two 14 AWG wires, or 14AWG cable.
