DynaLock TJ21 – Frequently Asked Questions
1) What does the DynaLock TJ21 kit actually do to a 2012 maglock?
The TJ21 converts a DynaLock 2012 magnetic lock into a 2012-TJ21, meaning the lock mounts on the top jamb instead of the frame face. It ships with the "Z" armature bracket and mounting hardware, plus the "L" lock conversion bracket that the 2000 Series kits include.
2) Will the TJ21 top jamb kit work on an outswing door?
No. DynaLock's top jamb conversion kits are for top jamb mounting on inswing doors. An outswing opening needs a different mounting approach, not this kit.
3) Which DynaLock lock series can be converted with a top jamb kit?
The top jamb conversion kits cover DynaLock 2000, 3000 and 2280 Series magnetic locks. The TJ21 is the specific kit for the 2012, which is a 2000 Series lock, so it is not the right kit if you have a 3000 or 2280 lock.
4) Is there an equivalent to the DynaLock TJ21 kit for mounting a maglock on a glass door instead of a top jamb inswing application?
No. The DynaLock TJ21 is a top jamb conversion kit that adapts 2000, 3000 and 2280 Series locks to top jamb mounting on inswing doors, and it ships with a Z armature bracket and mounting hardware plus an L lock conversion bracket for the 2000 and 2280 kits. For a frameless or glass door opening, Securitron Glass Door Accessories are the mounting accessory line built for that condition, and Securitron also offers the SWB SAM Wood Bracket for mounting to a wood substrate. Those are different mounting conditions, not alternate versions of the TJ21 bracket set.
5) I have a glass door or a frameless opening, not a top jamb. Is there an alternative to the TJ21?
The TJ21 assumes a conventional top jamb on an inswing door. For glass doors, Securitron's Glass Door Accessories line covers that mounting problem instead. If you are surface mounting rather than jamb mounting, the Securitron SAM Surface Mount Kit Accessories and the SWB SAM Wood Bracket are the corresponding brackets in that family.
6) What should I use instead of the DynaLock TJ21 if I need a surface mount bracket rather than a top jamb conversion?
The DynaLock TJ21 addresses top jamb mounting on inswing doors for 2000, 3000 and 2280 Series locks. If the lock is instead being surface mounted, Securitron SAM Surface Mount Kit Accessories cover that mounting method, and the Securitron SWB wood bracket handles a wood mounting surface. Confirm the bracket line matches the lock body you already have, since brackets are specific to the lock series they were designed around.
7) Is the LCN 8310-3803 conversion kit an alternative to the DynaLock TJ21?
No, despite both being called conversion kits. The LCN 8310-3803 is a 3V wireless conversion kit for jamb mount touchless actuators, so it changes how an automatic operator is triggered. The DynaLock TJ21 is mechanical bracketry that converts 2000, 3000 and 2280 Series locks to top jamb mounting on inswing doors using a Z armature bracket and, on the 2000 and 2280 kits, an L lock conversion bracket. One converts an actuator's signaling, the other converts a maglock's mounting.
8) I need to add door status or request to exit monitoring, not change the mounting. Does the TJ21 do that?
It does not. The DynaLock TJ21 is an installation accessory that converts 2000, 3000 and 2280 Series locks to top jamb mounting on inswing doors. Switch monitoring is a separate class of kit: Command Access offers the REX-KIT-ML request to exit kit for ML1-Series mortise locks and the SCHLBMKIT-ML latchbolt monitor switch kit for Schlage L9000 mortise locks in an SPDT configuration, with the CRSREXKIT-ED covering Cal Royal 22/98 and Sargent 80 Series exit devices. Those add signaling; the TJ21 only relocates the lock and armature.
9) For a maglock install, do I need power supply or relay accessories in addition to a TJ21 bracket kit?
The DynaLock TJ21 is a mechanical installation accessory for commercial electronic access control openings; it supplies the Z armature bracket, mounting hardware and, on 2000 and 2280 kits, the L lock conversion bracket, and carries no power or switching components. Power and control are separate items: the Adams Rite 4605 is a 115 VAC to 12/24 VAC transformer with a 40 volt-amp output, and the Locknetics RDB4 is a four-output relay distribution board. Size those against the lock's own voltage and current draw rather than against the bracket kit.
10) Is the TJ21 conversion kit suitable for commercial openings, and does it involve any wiring changes?
It is a commercial-duty accessory for electronic access control hardware. The TJ21 is purely a mechanical mounting conversion: brackets and hardware that reposition the maglock to the top jamb. The lock's own power and control wiring is unchanged by the kit.
11) Will a HES 1000-102 rain guard or Dortronics 6510/COV cover work in place of the DynaLock TJ21?
No, those protect a different component. The HES 1000-102 is a 1006 Series rain guard for rain or high dust areas, and the Dortronics 6510/COV is an anti-tamper alarm cover for 6500 Series pull stations and 5000 Series push buttons. Neither changes how a lock mounts. The DynaLock TJ21 supplies the Z armature bracket, mounting hardware and L lock conversion bracket needed to move a 2000 or 2280 Series lock to top jamb mounting on an inswing door.
