Von Duprin VON-9875-F-4-628 – Frequently Asked Questions

1) What door thickness does the Von Duprin 9875-F mortise fire exit device mount on?
Door thickness is 1-3/4 inches, the standard commercial door. Fasteners ship in the box for wood or metal doors at 1-3/4 inch and 2-1/4 inch thickness, so a thicker 2-1/4 inch door is covered on the fastener side.
2) Is the 9875-F/9975-F fire rated, and what standards does it carry?
Fire rated, yes. The 9875-F/9975-F is UL listed for fire exit hardware and certified to ANSI/BHMA A156.3 2014 Grade 1. The series also lists ANSI/UL 10C and CAN/ULC-S104 for fire-rated configurations, plus ANSI/UL 305 and CAN/ULC-S132 for panic. Being a fire exit device, it has no dogging, the latch stays active at all times.
3) Should I use a mortise exit device or a rim exit device on my door?
The 75 mortise version puts the latch in a lock case mortised into the door edge, which gives you a deadlocking auxiliary bolt and a faceplate with adjustable bevel, and it works on a single door or one leaf of a pair against a mullion or strike. It needs a mortise prep in the door, so it is usually specified new or as a swap for an existing mortise device. A rim device (no suffix in the 98/99 line) surface mounts with a rim strike and is the easier retrofit on an unprepped door. For a pair with no mullion, go to the 27 surface vertical rod or the 47/48 concealed vertical rod versions instead.
4) What trim do I need to order with the 9875-F/9975-F mortise device, and what does each function do?
Trim is a required selection. EO is exit only with no outside trim. DT is a rigid dummy pull (990DT). NL night latch (990NL-M) lets a key retract the latch. TP thumbpiece (990TP-M) and TP-BE with blank escutcheon are the 990 pull options. On the 996 side you get K knob or L lever in classroom (996K-M, 996L-M), passage with blank escutcheon (996K-BE-M, 996L-BE-M), and night latch (996K-NL-M, 996L-NL-M). NL and L trims are ordered LHR or RHR. The device itself ships field selectable for EO/DT/NL; for TP, K or L you remove the NL drive screw from the device.
5) Can I add electric latch retraction or request-to-exit monitoring to this mortise fire exit device?
Yes, both are orderable options. QEL gives quiet electric latch retraction. On the electrified side you can specify RX request to exit, RX2 double request to exit, WP-RX waterproof request to exit, E electric locking and unlocking of the trim or mortise lock, SS signal switch, or ALK alarm exit kit. Note that SS makes the device handed. Latchbolt monitoring (LX) and the CDSI/HDSI dogging indicators are offered in the series as retrofit kits.
6) What is the difference between the Von Duprin 98 and 99 mortise exit device?
Mechanically they are the same device, the difference is the look of the mechanism case. The 9875-F has a smooth case, the 9975-F has a grooved case. Both come in the same 12 finishes, from 605 bright brass and 626 satin chrome through 630 satin stainless, 710 dark bronze anodized and 711 flat black. Pick whichever matches the other openings in the building.
7) How far does the Von Duprin 9875-F push pad stick out from the door face?
Projection is 3-13/16 inches, and the center case measures 8 x 2-3/4 x 2-3/8 inches. The projection is what matters in a tight vestibule or where the door swings past a wall return, so check your clearance against that figure before mounting.
8) What size door does the 4-foot 9875-F/9975-F cover?
This is the 48 inch device size. UL listed fire exit hardware carries label and door opening size restrictions, so the device size has to be matched to the actual door width on a fire door, not just chosen by eye.
9) I need a 5 lb ADA push force or delayed egress on an exit device. Does the 98/99 series cover that?
Both are handled by upgrading to a different device in the 98/99 line rather than by a field kit. AX is the accessible device certified to the 5 lb force requirements of the 2010 ADA (chapters 404.2.7 and 309.4) and the 2013 California Building Code chapter 11B-309.4. CX is CHEXIT delayed egress, meeting NFPA and IBC, holding the door 15 seconds after a request to exit with a nuisance alarm sounding. XP is the patented two-piece latchbolt, available for both panic and fire applications.
10) If I only need a non-functioning pull on the outside of the door, do I need the full Von Duprin mortise exit device?
For the inactive or pull-only side you do not need a latching device. The Sargent 810 is a Grade 1 dummy pull trim, which is rigid pull hardware with no key or latch retraction. The Von Duprin 9875-F/9975-F covers that case differently: its trim function is field selectable among EO (exit only, no outside trim) and DT (dummy trim, 990DT), so the dummy pull can be specified as part of the device rather than as separate trim. Both are Grade 1; the difference is whether the opening needs the egress device at all or only outside pull hardware.
11) Which lever designs can I get with the 996L trim on this Von Duprin device?
Lever choice applies when you pick an L trim option. The default is the 06 lever, with 03, 07, 17 and the LAT Latitude lever as the alternates. If you are standardizing a building, the lever style is where you match the mortise locks and cylindrical locks on the non-exit doors.
12) I only need a dummy pull on the inactive leaf, not a whole exit device. What are my options?
On the 98/99 mortise device, DT selects the 990DT rigid dummy trim for pull operation. If what you actually want is standalone dummy trim rather than a device, the Sargent 810 Dummy Pull Exit Device Trim from the PE80 Series is a Grade 1 dummy-function trim in that role.
