2000 Series Electromagnetic locks

Model 2012-TJ21

2012-TJ21 Double Inswinging Door
Single coil with double (split) armature. Mounts to the face of the frame header. Recommended for traffic control only.600 Lbs. holding force per leaf

The 2000 Series is a full size 1200 lbs. holding force electromagnet. It is designed for life safety and high security on rated or nonrated doors and frames. Specify for commercial, industrial, or institutional openings when low cost and highsecurity are required

All 2000 Series locks are designed for ease of installation with adjustable mounting, field selectable voltage, and convenient wiring compartments. Optional integrated door and lock status sensors allow remote monitoring without the need to install separate “door contacts”.
The 2000 Series is offered in single, double, and split armature models for both outswinging and inswinging doors. The coil and housing assembly mounts rigidly to the door frame while the armature mounts to the door in a manner that allows it to pivot slightly to compensate for door irregularities. When the door is closed and the lock is energized the armature is magnetically bonded to the lock face, thus securing the door without utilizing any moving parts.

Standard Features

• Internal wiring compartment includes built-in circuit board attached to access cover to provide a convenient, plug in, concealed area for wiring connections.
• Low power consumption conserves energy, reduces operation cost, and extends battery backup time.
• A totally plated coil and armature provides protection against corrosion.
• A narrow backset of 1-1/2” may mean the elimination of other mounting brackets or filler plates.
• No residual magnetism - the door releases without delay when lock is de-energized.
• Multiple sensor and monitor options increases flexibility, security and compatibility with system equipment.
• Built-in spike suppression protects other solid state components within the system from damage when the lock is de-energized.
• Lifetime Warranty - American Made in the USA by DynaLock, with over 20 years experience in the manufacture of electromagnetic locks.

DynaLock 2012TJ21 628 – Frequently Asked Questions

1) What voltage does this DynaLock mag lock run on, and do I have to order it for 12 or 24 volts?
No voltage decision at order time on the standard coil. The 2000 Series lock is multi-voltage auto-sensing 12/24 VAC/VDC, field selectable. Current draw on the split armature (double) configuration is 748 mA at 12VDC and 420 mA at 24VDC. There is one exception: the low power coil option is 12V only at .16 Amps, and that is a single lock coil, so if you choose it you are locked to 12V.
2) How much space do I need on the frame header to mount this?
Plan for a unit measuring 1-3/4 x 2-3/4 x 11 inches. The 2000 Series runs a narrow 1-1/2 inch backset, which often lets you skip filler plates or extra mounting brackets that a deeper magnet would need. It is a surface mount lock, so the coil and housing fasten rigidly to the frame and the armature goes on the door.
3) Is this mag lock fail safe? What happens to the door when power drops?
It's fail safe by nature. An electromagnet holds only while energized, and the 2000 Series has no residual magnetism, so the door releases without delay the moment the lock is de-energized. There are no moving parts in the hold; the armature is simply magnetically bonded to the lock face while the door is closed. That behavior is what makes it usable on life safety openings tied into fire alarm release.
4) Should I use a split armature mag lock or two separate magnets on a double door?
A split armature unit like the 2012-TJ21 uses one coil and one wiring run to hold both leaves, which is cheaper and simpler but splits the 1200 lb magnet into 600 lbs per leaf, and DynaLock rates that for traffic control only. Two independent magnets, or a purpose-built double unit such as the Dorma EML320 for double doors or the Alarm Controls 1200D Series, give each leaf its own full holding force. Pick the split armature for classroom and corridor traffic control; pick a true double for security holding.
5) What is a cross-brand equivalent to the DynaLock 2012-TJ21 for a pair of doors?
The DynaLock 2012-TJ21 is a surface mount electromagnetic lock rated at 1200 lbs holding force on 12/24 VDC, using a single coil with a double (split) armature so each leaf of a double inswinging door holds at 600 lbs. For double-door openings from other makers, the Alarm Controls 1200D Series is a double magnetic lock, and the Dorma EML320 is a 1500 lb double-door electromagnetic lock with a fail safe electrically locked function and a fire rating. The Dorma unit is a two-magnet double lock rather than a split armature design.
6) Which magnetic lock should I use instead of the DynaLock 2012-TJ21 on a single door?
The 2012-TJ21 is built for a double inswinging door, splitting its 1200 lbs of holding force across two leaves at 600 lbs each. For a single leaf, the Alarm Controls 1200 Series is a single magnetic lock, the Dorma EML310 is a single-door 1500 lb electromagnetic lock offered with a door position sensor and optionally a bond alert, and the Schlage Electronics M390RFK is a 1500 lbs heavy duty single lock with door status monitor, magnetic bond sensor and relock time delay that drops in as a direct retrofit for a Locknetics 390+.
7) Do I need separate door contacts for monitoring, or can the lock report status?
Optional integrated door and lock status sensors are available on the 2000 Series, which lets you monitor the opening remotely without running separate door contacts. Those are options to specify, not standard content. What is standard on every model is the adjustable relock time delay (the former TD option) and built-in spike suppression that protects other solid state gear on the circuit when the magnet drops.
8) Can I use this DynaLock mag lock outdoors or on an exterior gate?
The 2000 Series has a totally plated coil and armature for corrosion protection, but it is not a weather rated unit. For exterior or wash-down openings, go with a purpose-built weather resistant magnet such as the Alarm Controls 1200WP Series, the Locknetics WMG Series, or the Dortronics 1000 Series, which has sealed electronics.
9) Is this magnetic lock approved for a fire rated door opening?
The 2000 Series is designed for use on rated or nonrated doors and frames, in commercial, industrial, and institutional openings. Note that the 2012-TJ21 specifically is recommended for traffic control only, so if the opening also needs a life safety hold, spec a different armature configuration in the series.
10) Is a shear lock the same thing as the DynaLock 2012-TJ21?
No. The 2012-TJ21 mounts to the face of the frame header, with the armature on the door face, and holds at 1200 lbs across a split armature. A shear lock such as the ROFU 8031-002 is a concealed-style unit rated at 2200 lb holding force on 12/24VDC with monitoring, and the Schlage Electronics 320M is a compact mortise sliding door electromagnetic lock at 1500 lbs holding force. Those mount into the door and frame rather than on the face of the header, so they are not interchangeable with a surface mounted magnet.
11) Does the low power coil option change the holding force?
The low power coil is a 12V only coil drawing .16 Amps, offered as a single lock coil. Lower draw is worth it when you are sizing a battery backup or running long wire, since low power consumption extends backup time and cuts operating cost. If your panel is 24V or you want the field selectable 12/24 VAC/VDC auto-sensing coil, order the standard version instead.
12) Is wiring this magnet into an access control panel a messy job?
Wiring lands in an internal compartment with a built-in circuit board attached to the access cover, so connections plug in and stay concealed inside the housing. Mounting is adjustable and voltage is field selectable, which means you are not committing to a fixed position or a fixed supply at the frame. The armature also pivots slightly on the door to take up door irregularities, so a slightly out-of-square leaf still bonds flat.
