DynaLock 3101C Series 15000 Lb. Delayed Egress System (Generation II)

Model 3121C-G2

3121C-G2 Double Outswinging Door
No Center Mullion. Double coil. Mounts to the underside
of the frame header. Master/slave configuration.

The 3101C Series is designed to satisfy egress codes and high security needs at the same time. The second generation 3101C system integrates a redesigned polymer housing cover and LED status indicator, while maintaining DynaLock’s proven and forgiving egress-sensing technology. In a typical installation, the door is normally closed and latched by the existing mechanical door hardware and magnetically secured by the 3101C Lock. Attempting to exit by by unlatching and pushing on the door will activate the 3101C delay egress timer. The audible and red LED will pulsate for 15 seconds (30 seconds field selectable). After the time delay has elapsed, the lock will release and the audible will sound continuously with a green LED, until the door is shut and the lock is reset. Reset and/or bypass are accomplished with a built-in keyswitch or remote signal. The system unlocks automatically when the 3101C is integrated with the building emergency fire alarm system or power is removed. Fire alarm contacts on the 3101C Lock are field selectable for NO and NC signals

Standard Features
• Microprocessor Controlled: An advanced digital processor manages all lock functions, without the need for an external system controller. Custom factory programs are available to meet varying application requirements and local building codes.
• Low Installation Cost: The user-friendly, micrometer style adjustment wheel simplifies calibration of delay egress sensor and works with existing door hardware. Does not require touch or electrified exit devices, electric hinges, door cords or special power supplies.

DynaLock 3121C-G2 – Frequently Asked Questions

1) Do I need electrified exit devices or electric hinges to use the 3121C-G2 delayed egress lock?
No. The system works with the existing mechanical door hardware and does not require touch bars, electrified exit devices, electric hinges, door cords, or special power supplies. Egress is detected by a concealed opto-electronic sensor that ignores wind, warpage, and door sag, and calibration is done with a micrometer style adjustment wheel.
2) How does the delayed egress sequence actually work on the DynaLock 3101C/3121C?
Push on the door after unlatching and the delay timer starts: the audible and red LED pulse for 15 seconds, field selectable to 30. When the delay elapses the magnet releases, the audible sounds steadily and the LED goes green until the door is closed and the lock is reset. Reset and bypass are done with the built-in keyswitch or a remote signal.
3) Does the 3121C-G2 release on a fire alarm or power loss?
Yes on both. The lock unlocks automatically when power is removed, and the onboard fire alarm contacts are field selectable for normally open or normally closed signals so it ties straight into the building fire alarm system. No external system controller is needed, since a microprocessor on board manages the lock functions.
4) What options do I have to specify when ordering a 3121C-G2?
Six option axes, each a yes or no: anti-tamper switch, auxiliary alarm output (a secondary set of SPDT delay egress alarm contacts), bypass monitor, door status switch, Dynastat force sensor, and egress sensor omitted. The low power coil option is a separate choice and cannot be paired with the Dynastat force sensor. If you are tying the opening into an access control head end, the door status switch and bypass monitor are the two that give you the feedback points.
5) Is the 3121C-G2 handed? I have a left hand reverse pair.
No handing to specify. The 3101C/3121C delayed egress locks are non-handed and surface mount for outswing single or double doors and inswing single doors. The 3121C-G2 itself is the double outswing version.
6) What are my options for a double door maglock if I do not need delayed egress at all?
Skip the delay egress hardware and look at a straight double-door magnet. The Alarm Controls 1200D Series is a double magnetic lock, and the Dorma EML320 is a double door electromagnetic lock rated 1500 lbs, fail safe (electrically locked), with a fire rating. Those cost less to install where the code official is not requiring a 15 second delayed egress sequence on the opening.
7) Can I use a standard mag lock like the Alarm Controls 1200D instead of the DynaLock 3121C-G2 and add a timer later?
They solve different problems. The Alarm Controls 1200D is a double magnetic lock for a pair of doors, and the Alarm Controls 1200 is the single-door version of the same family; both are holding magnets that depend on external devices for any release logic. The DynaLock 3121C-G2 integrates the delayed egress function in the lock itself: an opto-electronic egress sensor concealed in the housing, an on-board timer, audible and LED status, field selectable normally open or normally closed fire alarm contacts, and a built-in keyswitch for reset and bypass, with no external system controller required. It also works with existing mechanical door hardware, so it does not call for touch bars, electrified exit devices, electric hinges or door cords. If the code path on the opening calls for delayed egress, the integrated unit does that work in one box.
8) What should I order if I am replacing a Locknetics 390+ magnet rather than adding delayed egress?
For a direct swap of a Locknetics 390+, the Schlage Electronics M390RFK is built as a direct retrofit for that magnet, rated at 1500 lbs holding force with door status monitor, magnetic bond sensor and relock time delay, and classified heavy duty. The DynaLock 3121C-G2 is also a 1500 lb. unit but is not a retrofit part: it is a 22 inch double-coil assembly for a mullion-less pair of outswing doors and its purpose is delayed egress with a 15 second (30 second field selectable) timer and keyswitch reset. Use the retrofit part when you are matching an existing footprint, and the delayed egress unit when the opening's exit requirements changed.
9) My opening is a sliding door, not a swinging pair. Does the DynaLock 3121C-G2 work?
No. The 3121C-G2 is specified for outswing doors and mounts to the underside of the frame header for a swinging pair, using an optical sensor that detects the leaf being unlatched and pushed. For a sliding leaf, the Schlage Electronics 320M is a compact mortise sliding door electromagnetic lock rated at 1500 lbs holding force and classified heavy duty. A shear lock is the other family used where a surface magnet cannot be seen or where the door closes flush; the ROFU 8031-002 is a shear lock rated at 2200 lb holding force, 12/24VDC, monitored.
10) I need door position and bond monitoring on a pair of doors. How does the DynaLock 3121C-G2 compare to monitored magnets from other brands?
The 3121C-G2 builds monitoring in as ordering options rather than as fixed features: door status switch, anti-tamper switch, bypass monitor, auxiliary alarm output and the Dynastat force sensor are each selectable yes or no when you configure the unit, so you specify only the contacts the panel actually uses. Among the comparables, the Dorma EML310 with Bond Alert and Door Position Sensor carries bond and position monitoring as part of the model, the Schlage M390RFK includes a door status monitor and magnetic bond sensor, and the Dortronics 1000 Series includes an SPDT door position switch. If your panel needs a defined monitoring package on a single leaf, the fixed-configuration models cover it; for a mullion-less pair with a specific contact list, the configurable unit lets you match it exactly.
11) Will the DynaLock 3121C-G2 run on the same power supply as other 12/24V magnets I already have installed?
The 3121C-G2 is multi-voltage auto-sensing at 12 or 24 VAC/VDC and draws 849 mA at 12VDC or 480 mA at 24VDC in the double-coil configuration, and DynaLock states it does not require a special power supply. Comparable magnets in the same voltage band include the Dortronics 1000 Series at 12/24VDC field selectable, the Locknetics MG and WMG Series at 12/24VDC, and the ROFU 8512 and 8031-002 at 12/24VDC. Size the supply for the double-coil current draw, which is roughly double a single-door magnet on the same opening.
12) What finish does the DynaLock 3121C-G2 come in?
Satin aluminum, 628 (US28), which is the standard anodized aluminum finish that matches most commercial aluminum frames and storefront headers. The Generation 2 unit adds a redesigned polymer housing cover and LED status indicator over the original.
13) Is the DynaLock 3121C-G2 battery powered or does it need to be wired?
Hardwired only, no battery option. It takes 12 or 24 VAC/VDC on an auto-sensing input, and because the magnet releases when power is removed you should plan the supply and any backup with that fail safe behavior in mind.
14) Does the DynaLock 3121C-G2 come in the same 628 satin aluminum look as other magnets on my project?
The 3121C-G2 is supplied in 628 satin aluminum (US28), which is the standard architectural anodized finish for surface magnets. The Dorma EML310 and EML320 magnets in the comparable group are also catalogued in 628, so a mixed installation of single-door and double-door units reads consistently across the openings.
