Detex 08BN 689 – Frequently Asked Questions

1) Does the Detex 08BN trim come with a cylinder, or do I have to order one separately?
Both ways. The 08BN is sold with a cylinder or with no cylinder, and you pick that when you order. Take the no-cylinder version if you're keying the building yourself or matching an existing keyway, and the with-cylinder version if you just want it to work out of the box. Either way the cylinder it takes is a mortise cylinder, not a rim cylinder, so don't pull a rim cylinder off the shelf for it.
2) Can I change an exit device from storeroom to classroom without taking the device off the door?
Yes, on a Detex Value Series device. The mounting plate design means the function lives in the outside trim, so swapping to the 08BN classroom trim changes how the opening works without pulling the exit device off the door. That's the practical reason a school or facility keeps these on the shelf: one device, function changed at the trim when the room's use changes.
3) What is the closest equivalent to the Detex 08BN classroom lever trim from another manufacturer?
The Arrow SRX87 is the nearest match in function and form: it is a classroom function exit device trim with a Sierra lever and rose, the same classroom lever arrangement the Detex 08BN provides. The difference is the device family each one mounts to. The 08BN is built for Detex Value Series exit devices, while the SRX87 is made for Arrow S1150/S1250/ED910/PEC910 Series devices. Trim is device-specific, so match the trim to the exit device already on the door rather than to the lever style.
4) I need classroom function on a Corbin Russwin exit device, not a Detex. What trim covers that?
The Corbin Russwin K157ET is a Grade 1 classroom function trim with a rose, built for ED2200 and ED2400 Series exit devices, and it is a key only trim rather than a lever. So the operation differs from the Detex 08BN, which is lever entrance with the key locking or unlocking the lever. If the opening needs a lever to pull the door and the device is a Corbin Russwin ED2200 or ED2400, the K157ET gives you the classroom keying but not the lever handle.
5) What is the difference between classroom trim like the Detex 08BN and storeroom lever trim?
Classroom operation on the Detex 08BN means entrance by lever, with the key locking or unlocking the lever, so the lever can be left unlocked for a class period. Storeroom trim keeps the lever locked at all times and the key retracts the latch each time. The Deltana DDS-36 and LTED60LST are both storeroom function lever trims, for exit device 80 and exit device 60 respectively. Pick classroom when someone needs to leave the door unlocked from outside without propping it; pick storeroom when it must never be left unlocked.
6) We want to stop issuing keys to the classroom doors. What replaces the Detex 08BN with a code?
Two credential trims cover that. The BEST EXZ is an electronic keypad exit device trim with key override, from the EZ Series. The Dormakaba E-Plex E5010 is a Grade 1 electronic push button exit device lever trim with key override, fitting doors 1-3/8 inch to 2-1/4 inch thick. Both let staff enter on a code and keep a key as backup, where the Detex 08BN is mechanical and works on the mortise cylinder key alone. Confirm the trim matches the exit device family on the door before ordering.
7) Are the Sargent 802 and Von Duprin 379L-BE substitutes for the Detex 08BN classroom trim?
No. The Sargent 802 is a blank plate exit device trim with GTB design for PE80 Series devices, and the Von Duprin 379L-BE is a blank escutcheon trim for 55 Series rim exit devices. Blank trim gives the door an exterior face with no operating handle and no cylinder, so the door is exit only from inside. The Detex 08BN is classroom lever trim that provides entrance by lever with a key to lock or unlock it. If anyone needs to get in through that door, blank trim will not do the job.
8) I need a keyless lever trim for a panic device, not a keyed classroom one. What should I use?
Skip the 08BN, since it's keyed classroom and needs a mortise cylinder. For keyless, the Lockey 115P is a heavy duty keyless passage lever panic trim with the 1150 lock body, fitting doors 1-3/16 to 2 inches, and the Lockey 285P is a keyless mechanical panic trim with a lever, same door thickness range. For a code-entry approach, the Dormakaba E-Plex E5010 push button trim with key override covers 1-3/8 to 2-1/4 inch doors.
9) What's the difference between classroom trim and storeroom or nightlatch trim on an exit device?
Classroom, like the 08BN, gives you a lever that works for entry and a key that locks or unlocks that lever, so the door can be left unlocked during the day. Storeroom trim keeps the outside locked at all times and only a key retracts the latch, which is what the Deltana DDS-36 and LTED60LST do. A nightlatch pull like the Sargent 814 PSB is key-only entry with a pull instead of a lever. Passage trim, such as the Deltana LTED80LP, never locks at all. Pick classroom when staff need to secure the room from the corridor side without a full re-key routine.
10) Can the Detex 08BN trim be rehanded in the field for a left hand door?
Detex publishes rehanding videos for both narrow stile and wide stile lever trim, and the 08BN install instructions cover the 08, 09 and 14BN together. Handing is handled at install rather than by ordering a separate left or right part number, so the order form only asks you for finish and whether you want the cylinder.
11) What else do I need to order with the Detex 08BN to finish the job?
If you take the no-cylinder version, you need a mortise cylinder in your keyway with the correct cam for the trim. You also need a compatible Detex Value Series exit device on the push side, since this is trim only and does not latch anything by itself. Detex supplies the install instructions for the 08, 09 and 14BN trims and a separate sheet for EU2W.
12) How does entry function lever trim differ from the classroom Detex 08BN?
The Deltana LTED80LS is an entry function lever trim for exit device 80. Entry function is locked or unlocked from the trim side and unlocking is typically a button or turn rather than the key holding the lever unlocked. The Detex 08BN is classroom function on a mortise cylinder, so the state of the lever is changed only with a key. On school and tenant corridor doors where you do not want occupants changing the lock state without a key, that difference is the deciding one.
13) The door does not need key control, just a lever to get back in. What is simpler than the Detex 08BN?
Look at keyless mechanical trim. The Lockey 115P is a heavy duty keyless passage lever panic trim with a 1150 lock body, and the Lockey 285P is a keyless mechanical panic trim with a lever handle; both fit doors 1 3/16 inch to 2 inch thick. Neither takes a cylinder. The Detex 08BN takes a mortise cylinder and its classroom operation depends on that key to lock and unlock the lever, so if nobody is going to carry a key, the keyless trims remove the cylinder from the order entirely.
14) The outside of the door should always be open. Is there a lever trim for that instead of the Detex 08BN?
Yes. The Deltana LTED80LP is a passage function lever trim for exit device 80, meaning the lever always retracts the latch and there is no locking from the outside. The Detex 08BN is classroom function, where the key locks or unlocks the lever, and it takes a mortise cylinder. Choose passage trim for corridor and stairwell-side doors that are never secured, and classroom trim where the lever must be lockable.
15) Can a nightlatch pull or an offset pull handle be used in place of the Detex 08BN?
They serve a different opening. The Sargent 814 PSB is a heavy duty nightlatch pull trim for 80 Series devices, where the key retracts the latch and the pull only pulls the door open. The Sargent 862 is an offset pull handle for exit devices in the P800 Series with no latch operation at all. The Detex 08BN gives lever entrance with the key locking or unlocking that lever, so the door can be left in an unlocked state. Choose the nightlatch pull for a service or delivery door and the classroom lever trim where the door alternates between locked and free entry.
16) Is dummy lever trim the same thing as the Detex 08BN classroom trim?
No. The Corbin Russwin x650ET is a Grade 1 heavy duty dummy lever trim with rose for ED7000 Series exit devices. A dummy lever is fixed and does not retract the latch, so it is a pull only. The Detex 08BN is classroom function lever trim that operates the device and uses a mortise cylinder to lock or unlock the lever. Both look like a lever on the outside of the door, which is exactly why they get ordered by mistake.
17) We are standardizing classroom doors across a school. Does the Detex 08BN or an electrified device make more sense?
Those solve different problems. The Detex 08BN is mechanical classroom trim, changed by key at the door, and its mounting plate design lets you change function by swapping the outside trim without pulling the exit device off the door. The ACSI ED4200-W036 is a Grade 1 wide stile rim exit device with 24 volt AC/DC electric latch retraction, which is the device itself and requires power and wiring to the opening. Use electric latch retraction where doors must be released from a central point on a schedule, and mechanical classroom trim where the teacher secures the door at the lever.
18) Is the Detex 08BN a lever or a knob, and is it rated for commercial traffic?
It's an S-lever trim, commercial grade, built to take the same abuse as the panic device it mounts to. Lever operation is what most facilities want on classroom and corridor doors for accessible operation. Detex publishes install instructions covering the 08, 09 and 14BN trims together, so the mounting is common across those three functions.
