14/4 Solid Copper Fire Alarm Cable - FPLR Riser Rated, Red, Data, 1000ft

This is the four-conductor riser-rated fire alarm cable in the heavier 14 AWG gauge: four solid bare copper conductors, insulated black, red, brown, and blue in PVC, under a red PVC jacket listed FPLR under NEC Article 760 for power-limited fire alarm circuits. Four conductors means two circuits in one pull: the power pair and the alarm pair for four-wire smoke detectors, a notification circuit and an initiating circuit to the same device box, or a relay module's control and monitor pairs, each on a 14 AWG conductor with about 60% of the loop resistance of 16 AWG, so a long or heavily loaded notification circuit stays inside the panel's voltage-drop limit. It's a standard-grade, unshielded cable, which is the everyday construction for notification and initiating circuits on a quiet route.

FPLR covers the vertical runs between floors of a multi-story building and every ordinary in-wall and in-ceiling run that isn't a return-air plenum. The red jacket is the fire alarm identification that inspectors and future technicians expect to see. The cable is UL Listed and made in the USA, and it comes on a 1000 ft wooden spool.

Features

• FPLR riser rated. Listed under NEC Article 760 for power-limited fire alarm circuits in riser shafts, vertical runs between floors, and general in-wall and in-ceiling use.
• Four 14 AWG solid bare copper conductors. Two circuits in one cable, each with about 60% of the loop resistance of 16 AWG, for four-wire detectors, combined notification and initiating runs, and control modules.
• PVC insulation, black, red, brown, and blue. Four distinct colors so each pair keeps its polarity and identity from the panel to the device.
• Red PVC jacket. The standard fire alarm identification, so the cable is recognizable in a tray, a riser, or a junction box years after it's installed.
• Standard grade, unshielded. The everyday construction for notification appliance and initiating device circuits, and the easier one to terminate.
• 300 V, 75 °C. The ratings a power-limited fire alarm circuit calls for.
• 6.38 mm outer diameter. A 0.381 mm jacket wall, sized to fit standard fire alarm fittings and connectors.
• UL Listed, made in the USA.
• 1000 ft wooden spool. Put it on a spool stand and it pays out cleanly.

Where It Fits

It suits four-wire smoke and heat detector circuits that need a separate power pair alongside the alarm pair, device runs that carry both a notification circuit and an initiating circuit to the same location, relay and control modules with a control pair and a monitor pair, duct detector and damper control wiring, riser runs between the fire alarm control panel and floor terminal cabinets where two circuits share a route, long notification appliance circuits with a high count of horns and strobes, and any power-limited fire alarm run where two 14 AWG pairs in one pull save a second cable.

Good to Know

Don't put both legs of a Class A loop in the same cable. NFPA 72 requires the outgoing and return conductors of a Class A circuit to be routed separately so that one fault can't take out both, and a four-conductor cable running out and back defeats that; use it for two different circuits, or for the power and alarm pairs of a four-wire device. Run the voltage-drop calculation before you pick a gauge: a 14 AWG pair is about 5 ohms per 1000 ft round trip, so a notification circuit drawing 1.5 A at the far end of a 300 ft run loses about 2.3 V, and a 2 A load at 400 ft loses about 4 V; past that, step up to 12 AWG. A speaker circuit is figured on impedance and wattage rather than current, using the amplifier manufacturer's tables. FPLR covers risers and general use but not return-air plenums; a run through a plenum ceiling needs FPLP. This is a standard-grade cable, so for an addressable panel's signaling line circuit use the data-grade shielded 14/4, which is built to the tolerances those loops specify and also covers a route that shares a riser or a tray with power, lighting, or elevator wiring. The cable is listed for fire alarm circuits under Article 760, and the AHJ has the final say on using it for anything else, so if it's going on a security, intercom, or control circuit, check first. Keep fire alarm cable separate from power conductors in raceways and boxes, as the code requires for power-limited circuits. Four 14 AWG solids under one jacket make a stiff cable, so give it a generous bend radius, use device terminals rated for it, and size the backboxes accordingly. The PVC jacket isn't UV stabilized or rated for wet locations or burial, so an outdoor device should be fed through conduit or from a cable rated for it.
