16/2 Fire Alarm Riser FPLR Solid Bare Copper Cable – 1000ft – Yellow

16/2 Fire Alarm Riser Cable – Technical Overview to Meet Your Needs

16/2 fire alarm cable is specifically engineered for life-safety and low-voltage fire protection systems. It features two 16 AWG conductors (stranded or solid) designed for consistent signal transmission and high flame resistance with compliance with UL 1424 and NEC Article 760.

Key Specifications of the 16/2 Fire Alarm Riser Cable

16/2 fire alarm riser cable is a popular choice. This type of cable is widely used for interconnecting fire alarm control panels, notification appliances, and initiating devices in commercial and residential buildings.

Conductor and Insulation Design

The cable consists of two 16 AWG copper conductors with precision stranding to ensure mechanical flexibility and stable DC resistance. Insulation is typically made of PVC or cross-linked polyethylene. It is designed to withstand elevated temperatures and resist dielectric breakdown.

16/2 twisted shielded fire alarm cable includes an overall aluminum foil shield and drain wire. This can help in minimizing electromagnetic interference (EMI) from nearby circuits. In addition to that, 16/2 twisted fire alarm cable uses twisted pair geometry. This can help in reducing crosstalk and improving signal integrity across long distances.

Fire-Resistance and Rating

This is a riser-rated cable (CL3R, FPLR and it is tested to prevent flame propagation in vertical shafts. Riser fire alarm cable is designed for non-plenum spaces, such as between floors or vertical conduits. This helps it to stand out from plenum-rated variants.

It also complies with UL 1666 Riser Flame Test for vertical applications. Fire alarm cable 16/2 is certified for use in life-safety circuits. This is vital in ensuring system reliability during fire events.

Jacket and Environmental Suitability

The outer jacket is PVC, offering abrasion resistance, oil resistance, and impact protection. For outdoor installations:

• 16/2 direct burial fire alarm cable comes with a water-blocking gel or polyethylene jacket, providing moisture resistance for underground runs.
• Sunlight-resistant formulations are available for above-ground outdoor applications.

Applications of 16/2 Fire Alarm Cable

• Fire alarm control panel to smoke detector circuits.
• Notification appliance circuits (horns, strobes, bells).
• Auxiliary systems like emergency communications or security integration.
• Long vertical riser shafts between building floors.

Technical Specifications (Typical)

Buying Guide – Key Considerations

When selecting a 16/2 fire alarm riser cable, evaluate the following technical factors:

• Conductor Type: Solid for permanent installs; stranded for flexibility in conduit runs.
• Shielding: Choose 16/2 twisted shielded fire alarm cable where EMI protection is required.
• Application Rating: Verify riser vs plenum depending on building code requirements.
• Environmental Rating: Opt for 16/2 direct burial fire alarm cable for underground use.
• Compliance: Confirm UL 1424, NEC Article 760, and local AHJ approval.
• Length Requirements: Standard spools available in 500 ft. and 1000 ft. reels.

FAQs – 16/2 Fire Alarm Riser Cable

What is 16/2 fire alarm cable used for?

It is used to connect fire alarm devices like detectors, strobes, and control panels within riser shafts or vertical runs.

What is the difference between riser-rated and plenum-rated fire alarm cable?

Riser-rated (FPLR) is for vertical shafts and conduits, while plenum-rated (FPLP) is designed for air-handling spaces with stricter flame and smoke requirements.

When should I use 16/2 twisted shielded fire alarm cable?

Shielded versions are recommended where electromagnetic interference (EMI) is present. This includes places near elevators, motors, or high-voltage circuits.

Can a 16/2 fire alarm cable be buried directly?

Yes, but only 16/2 direct burial fire alarm cable with a polyethylene jacket and moisture barrier is suitable for underground installation.

What is the maximum distance for 16/2 fire alarm cable runs?

The distance depends on voltage drop calculations, but typically 16 AWG supports up to 1,000 feet for most notification circuits at 24V DC.

Is 16/2 fire alarm cable compatible with addressable fire alarm systems?

Yes, provided it meets manufacturer specs for loop wiring and capacitance. Shielded versions are often preferred to reduce noise on signaling lines.

Can I run 16/2 fire alarm cable with power cables?

No, per NEC Article 760, fire alarm cables must be isolated from power conductors unless rated for combined use.
