22/6 AWG Riser Security Alarm Cable - CMR/CL3R Rated, Shielded, 1000ft Gray

This is the six-conductor shielded riser cable for the sensors, keypads, and readers of a security system on an electrically noisy route: six 22 AWG stranded bare copper conductors, each a different color, under an overall aluminum foil shield and a gray PVC jacket with a rip cord, listed CL3R under NEC Article 725 for Class 3 power-limited circuits (and by the code's substitution rules for Class 2 as well) and CMR under Article 800 for communications. Six conductors means three circuits in one pull: a card reader with power, a data pair, and an LED or tamper line; a keypad on a four-wire bus with a tamper pair; a motion detector with power, alarm, and tamper. The shield is for the data and audio conductors in that bundle: a reader pair or a keypad bus that has to share a riser or a wall with lighting and power wiring picks up less noise under foil than it would bare. 22 AWG is the gauge most sensor and keypad wiring is specified at, and the 7-strand conductors bend around a wall cavity and land in a terminal block more easily than solid wire.

CL3R and CMR cover 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 cable is ETL Listed and RoHS compliant, and it comes in a 1000 ft pull box with sequential footage marks on the jacket.

Features

• Riser rated two ways. CL3R under NEC Article 725 and CMR under Article 800, so it's listed for riser shafts, vertical runs between floors, and general in-wall and in-ceiling use on security, control, and communications circuits, and the CL3R listing covers Class 2 circuits under the code's substitution rules.
• Six 22 AWG stranded bare copper conductors. Three circuits in one pull, at the gauge most sensor, keypad, and reader wiring is specified at, on 7-strand conductors that bend around a wall cavity and seat in a terminal block without fighting.
• Overall aluminum foil shield. 100% coverage against induced noise from lighting, motor, and power circuits sharing the riser or the wall, for the reader and keypad data conductors in the bundle.
• Six distinct colors. Black, red, white, green, brown, and blue, so every circuit is identifiable at both ends without a meter.
• PVC insulation and jacket, with a rip cord. Flexible, with a 0.015 in jacket wall over the shield; pull the cord and the jacket opens without a blade near the foil or the conductors.
• Gray jacket. Reads as general-purpose low-voltage in a wall or a tray, and stays distinct from red fire alarm and blue data cable.
• 300 V, 75 °C. The ratings a Class 2 or Class 3 circuit calls for.
• 4.55 mm outer diameter. Slim enough to bundle by the dozen and fish through a wall or a tight ceiling.
• ETL Listed, RoHS compliant.
• 1000 ft pull box. Sequential footage marks on the jacket; pays out from the box without a spool stand, and the box stacks in a van.

Where It Fits

It suits card readers and keypads on access control doors that need power, a data pair, and an LED or tamper line, security keypads and touchscreens on a panel bus with a tamper loop, motion detectors and glass-break sensors with power, alarm, and tamper routed past fluorescent lighting or motor circuits, intercom and entry-phone stations with power, audio, and a door-release pair, riser runs between a security panel and a floor's zone expander or reader controller alongside power wiring, and any multi-circuit low-voltage run through the walls and risers of a home, apartment building, office, or store where the ceiling space isn't a return-air plenum and the route is electrically noisy.

Good to Know

Ground the shield's drain at the panel or controller end only and tape it back at the device end; a shield grounded at both ends becomes a loop that picks up the noise it was meant to reject. Check the reader or panel manufacturer's wiring guide before you pull, since Wiegand, RS-485, and some keypad buses have maximum lengths at 22 AWG or specify a twisted pair, and a foil shield adds capacitance that can shorten the rated run on a high-speed bus. Keep the current light: a 22 AWG pair is about 32 ohms per 1000 ft round trip, so a 12 V reader drawing 200 mA at 300 ft loses about 1.9 V, which is already close to what some readers tolerate; feed strikes, sirens, and anything else that draws real current on an 18 AWG pair and keep this cable for the reader and its data. Keep the circuits in their classes: Class 2 and Class 3 circuits can share this cable, but a Class 1 circuit can't, and the NEC requires power-limited wiring to stay separated from power conductors in raceways and boxes. Stranded conductors want a ferrule or a proper fold-back before they go under a screw terminal; a stray strand is the short that takes a zone into trouble. Use the rip cord: score the jacket an inch, find the cord, and pull it back to where you want the break, then trim; it's faster than ringing the jacket and it can't nick the foil or an insulated conductor. CL3R and CMR cover risers and general use but not return-air plenums; a run through a plenum ceiling needs a CL3P cable. If the route is quiet, the unshielded 22/6 riser does the same job for less and terminates faster. The jacket isn't UV stabilized or rated for wet locations or burial, so an outdoor reader or keypad should be fed through conduit or from a cable rated for it.
