Falcon RM170 7FT 2IN US28 – Frequently Asked Questions

1) What length Falcon RM170 mullion do I need for an 8 foot door opening?
The RM170 comes in four lengths, sized to the frame height: 7 ft 2 in, 8 ft 2 in, 9 ft 2 in and 10 ft 2 in. Order by the opening height, so an 8 foot opening takes the 8 ft 2 in mullion. The extra 2 inches is the engagement into the head and floor fittings, not slack you cut off.
2) Can I use the Falcon RM170 mullion on a fire rated door pair?
No. The RM170 carries no fire rating, so it should not go into a fire rated opening. Fire rated pairs need a fire rated mullion listed with the device, or a set of fire exit devices with vertical rods. Use the RM170 on non-rated openings only.
3) Can a Von Duprin 040061 QEL conversion kit be used in place of a Falcon RM170 mullion on a pair of doors?
No. The two solve different problems. The Falcon RM170 is an aluminum mullion for 1790 rim exit devices, a vertical member that stands in the opening between a pair of doors and gives each rim device something to latch into. The Von Duprin 040061 is a QEL modular conversion kit for 33A/35A/98/99 series 3-foot and 4-foot exit devices that adds quiet electric latch retraction to the device itself. If the goal is to let two rim devices work on a pair of doors, the RM170 is the part; a latch retraction kit changes how a device retracts and does nothing for the opening between the leaves.
4) For a fire rated pair of doors, does the Falcon RM170 or a Von Duprin 040070/040071 dogging kit apply?
Neither carries a fire rating. The Falcon RM170 aluminum mullion for 1790 rim exit devices is listed with a fire rating of No, and the Von Duprin 040070/040071 cylinder dogging with indicator conversion kit for 36 inch and 48 inch 33A exit devices is also rated No. On a fire rated opening, specify a fire rated mullion and fire rated device hardware instead; both of these are intended for openings where no fire rating is required.
5) Should I use a removable mullion with rim devices, or vertical rod exit devices on a pair of doors?
Two ways to secure a non-rated pair. A mullion plus two rim devices gives you a simpler device on each leaf, latching into the mullion, and the mullion comes out when you need the whole opening. The tradeoff is a post in the middle of the doorway day to day. Surface vertical rod devices latch at the head and the threshold instead, leaving a clear opening with no center post, at the cost of rods on the doors and more to keep adjusted. High traffic openings that move carts and stock usually go rim plus removable mullion.
6) Do I get strikes and floor fittings with the Falcon RM170, or do I order those separately?
The RM170 is sold as the mullion itself, an installation accessory for the 1790 device. The strike that the rim latch catches is part of the device package, and the top and bottom mounting fittings that hold the mullion in the frame are what you want to confirm on the order before the crew shows up. If you are replacing a broken mullion and reusing existing fittings, order the length that matches the opening and keep the old top and bottom hardware in place.
7) I need to replace a damaged mullion on a Falcon 1790 opening. Do I need to change the exit devices too?
No. The RM170 replaces the mullion alone. The 1790 rim devices on each leaf stay where they are, since the RM170 is the mullion Falcon builds for that device. Measure the frame height and order the matching length, 7 ft 2 in, 8 ft 2 in, 9 ft 2 in or 10 ft 2 in, and pick the finish that matches the frame.
8) Is the Accentra 7110/7120 top latch component an alternative to a Falcon RM170 mullion?
No. The Accentra 60-7010-0049-999 is a top latch replacement component for 7110/7120 exit devices, an internal part that restores latching on an existing device. The Falcon RM170 is a mullion, a separate aluminum member for the opening, supplied in 7 foot 2 inch, 8 foot 2 inch, 9 foot 2 inch and 10 foot 2 inch lengths for 1790 rim exit devices. Buy the Accentra part when a device has a failed top latch; buy the RM170 when a pair of doors needs a mullion for rim devices to strike.
9) A rim exit device needs a cylinder for keyed access on a mullion opening. Is the Falcon RM170 that part?
No. The Falcon RM170 is an aluminum mullion for 1790 rim exit devices and provides the mounting and structural interface in the opening. Keyed access through a rim device comes from a rim cylinder housing such as the Arrow 16RCR-27 SFIC rim housing, 6/7-pin, in the 24/25 series. A mullion opening that also needs keyed entry takes both: the mullion between the leaves and a cylinder in the device.
10) What finishes does the Falcon RM170 aluminum mullion come in?
Three anodized aluminum finishes: US28 clear aluminum anodized, DC13 dark bronze anodized, and DC35 black anodized. All four lengths are offered in all three, so you can match the mullion to storefront framing that is already clear, bronze or black without changing the length you need.
11) Is an aluminum mullion strong enough for a commercial entrance?
Falcon rates the RM170 for commercial use, and aluminum is what most removable mullions on aluminum storefront and office entrances are made from. It is lighter to lift in and out than steel, which matters on a mullion staff take out regularly, and it resists corrosion. For high security or exterior openings where forced entry is the concern, a steel mullion is the heavier duty choice.
12) Can I standardize one mullion across a building with different door heights?
Not with a single part number. Mullion length has to match the opening, and the RM170 covers 7 ft 2 in through 10 ft 2 in in four steps. What you can standardize is the finish and the device line: run 1790 rim devices and one anodized finish across the property, then order the mullion length per opening. That keeps keying, trim and spare parts common even where frame heights differ.
