Detex F-20 HD 628 97 36X84 – Frequently Asked Questions

1) Can I use the Detex 20 Advantex vertical rod device on a pair of doors without a mullion?
That is exactly what a surface vertical rod device is for. The Detex 20 Advantex latches at the head and at the threshold rather than into a center strike, so a pair of fire rated doors can be secured with no removable mullion in the opening. If you would rather keep a mullion and use rim devices, that is a different device type.
2) Is the Detex 20 Advantex fire rated, and what grade is it?
Fire rated, and Grade 1 super-heavy-duty. That combination is what lets it go on a labeled fire door assembly in a school, hospital, or municipal building where the inspector is checking both the label and the duty level. Note that a fire exit device has no mechanical dogging permitted in service, so specify accordingly.
3) Will the Detex 20 work on a narrow stile aluminum storefront door?
No. The 20 Advantex is a wide stile device, which means it needs the broader stile of a hollow metal or wood door. On a narrow stile aluminum glass door you need a narrow stile exit device instead.
4) What door heights does the Detex 20 Advantex cover, and do I need special rods for a 10 foot door?
Rod length is chosen by door height at time of order: 84 inch, 96 inch, or 120 inch. The 120 inch option is the one to specify for a 10 foot leaf, so no separate rod extension kit is needed. Device width is 36 inch.
5) What is the less bottom rod option on the Detex 20 for, and should I use it?
Less bottom rod (LBR) deletes the bottom rod and drop bolt so the door latches only at the head. Crews specify it where floor debris, carpet, or a sloped threshold fouls a bottom bolt, and it makes cleaning easier in kitchens and hospitals. Ordered with the bottom rod, you get a hardened steel bottom drop bolt with a dust proof strike and an ADA ramped bolt cover.
6) What outside trim choices are there if I need the Detex 20 to be lockable or keyed from outside?
Four outside trim choices: 01C blank plate, 03C night latch trim, 08D classroom lever trim, or Exit Only with no outside trim at all. Pick 08D if staff need lever entry from the corridor side, 03C for key-only entry, and Exit Only for a pure egress door.
7) What electrified options can I get on the Detex 20 Advantex?
Four: EA hardwired electric alarm, EX request to exit signal switch, EE delayed egress, and ER EX electric latch retraction with a request to exit switch. EE is the one for a controlled egress door on an access control system; ER EX is what you use when the door needs to free-wheel on a card read or scheduled unlock. You can also order it non-electrified.
8) Which fire rated vertical rod exit devices can be used instead of the Detex 20 Advantex on a 36 by 84 opening?
Two fire rated peers cover that opening. The Delaney F9100 Series (DLY-694300) is a Grade 1 fire rated heavy duty vertical rod device for a 36 by 84 door in aluminum finish, and the Marks USA M9900FVR is a fire rated 36 by 84 vertical rod device that is exit only and non-handed. The Detex 20 Advantex differs in that it is handed field reversible and offered in 84, 96 and 120 inch heights with outside trim choices including 03C night latch and 08D classroom lever, so if the opening needs keyed outside access or a taller door height, the Detex 20 is the one that carries it.
9) What is the closest wide stile surface vertical rod alternative to the Detex 20 Advantex fire rated exit device?
The Von Duprin 8827-3FT is the nearest wide stile surface vertical rod peer: 88 Series, Grade 1, 3 ft, for 1-3/4 inch doors. The difference that decides the order is fire rating - the Detex 20 Advantex is fire rated Grade 1 super-heavy-duty, while the 8827-3FT is not fire rated. On a fire door assembly the Detex 20 is the one that applies.
10) I need a 48 inch door leaf, not 36 inch - what vertical rod device covers that?
The Detex 20 Advantex fire rated wide stile device is built for a 36 inch device size. For a 48 inch leaf, the Marks USA MARM9900F-VR is a 48 by 84 fire rated vertical rod panic device, exit only, and the Marks USA M9900VR-48X84 is a 48 by 84 vertical rod panic device that is exit only and not fire rated.
11) Is the Cal-Royal 9860 vertical rod device a substitute for the Detex 20 Advantex?
Not on a fire door. The Cal-Royal 9860 is a heavy duty Grade 2 surface vertical rod device, exit only, and is not fire rated. The Detex 20 Advantex is Grade 1, super-heavy-duty, and fire rated, with ADA ramped bottom bolt cover and hex or cylinder dogging. The 9860 suits a non-rated opening; it does not stand in where a fire exit hardware listing is required.
12) Do I have to order the Detex 20 Advantex handed, or can it be reversed in the field?
You pick the hand on the order, Right Hand Reverse or Left Hand Reverse, but the device itself is field reversible, so a stocked unit can be flipped on site if the opening turns out opposite to the drawing.
13) Does the Detex 20 come with dogging, and which type should a property manager order?
Three choices: cylinder dogging, 1/8 turn hex dogging, or less dogging. Cylinder dogging keeps control with whoever holds the key, hex dogging needs only the hex wrench. Keep in mind dogging is not used on a fire rated opening, so less dogging is the common pick on labeled doors.
14) Can the Detex 20 be ordered for a hurricane rated opening?
Yes. Two rating add-ons are offered: H for hurricane, and HF for hurricane plus fire rated. Coastal and Florida jobs that need both the impact rating and the fire label take HF.
15) Can I use the Detex 20 Advantex on an exterior door exposed to weather?
It is not a weatherized device. For an exposed exterior opening that sees driving rain, look for hardware built for weatherized service; the hurricane rated H or HF version addresses impact, not weather sealing.
16) Do I need paper templates to install the Detex 20, or is door prep included?
Detex supplies a patented mounting plate and strike locator system in place of paper templates, which is what keeps the top latch and bottom bolt in line with their strikes on the first try. Printed door prep templates, installation instructions, and a parts list are published by Detex for the 20 Series if your shop preps doors in advance.
17) Is the Detex 20 Advantex bottom bolt going to be a trip hazard in an accessible route?
No. The device ships with an ADA ramped bottom bolt cover over the drop bolt, plus a heavy duty angled end cap on the push rail. If you want the floor completely clear, order the less bottom rod configuration instead.
18) What is a simpler Grade 1 vertical rod exit device if I do not need fire rating or electrified options?
For a non-rated opening, the Imperial USA ED-VR531 is a 500 Series Grade 1 wide stile surface vertical rod device, exit only, at 36 inches, and the Delaney 8100 Series (DLY-8100-3684) is a Grade 1 vertical rod device for a 36 by 84 door, also not fire rated. The Detex 20 Advantex carries the fire rating plus electrified choices such as EA hardwired electric alarm, EX request to exit, EE delayed egress and ER EX electric latch retraction, which those two do not.
19) Can I standardize my building on one vertical rod device across rated and non-rated openings?
Within the Delaney range you can pair the F9100 Series (DLY-694300), Grade 1 fire rated for a 36 by 84 door, with the 9100 Series (DLY-692301), Grade 1 non-rated for the same 36 by 84 door in stainless steel, keeping one series family across both. The Detex 20 Advantex approaches it differently: it is a single fire rated Grade 1 super-heavy-duty platform offered in eight finishes from 605 polished brass through 630 brushed stainless and 693 black painted, so one device type covers rated openings throughout a facility and matches finish across them.
20) Which vertical rod exit device should I use on a hurricane rated opening?
The Detex 20 Advantex is offered with H hurricane and HF hurricane and fire rated options, so it can be ordered for that condition. The comparable vertical rod devices - including the Von Duprin 8827-3FT, the Marks USA M9900VR and the Cal-Royal 9860 - are specified by grade and fire rating only, so for a hurricane requirement the Detex 20 is the device to specify.
21) What finishes does the Detex 20 Advantex come in for matching other doors in my building?
Eight finishes: 605 polished brass, 606 brushed brass, 611 polished bronze, 612 brushed bronze, 613 oil rubbed bronze, 628 brushed aluminum, 630 brushed stainless steel, and 693 black painted. Exposed surfaces are finished over stainless steel with a PVD coating, which holds up better than plated brass in a high-touch corridor. 630 and 628 are the usual matches for existing commercial hardware.
22) Do any of the alternatives avoid specifying handing the way the Detex 20 does?
The Marks USA M9900VR and the fire rated M9900FVR are non-handed 36 by 84 vertical rod devices, exit only, so handing is not part of the order. The Detex 20 Advantex is ordered right hand reverse or left hand reverse and is field reversible, which is what allows it to accept outside trim such as 03C night latch or 08D classroom lever rather than exit only.
