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

Model 3121C2-G2

3121C2-G2 Double Outswinging Door
With 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.
• Auto-Sensing Power Input: 12 or 24 VDC/VAC
• Auxiliary Alarm Output: Optional new secondary set of SPDT delay egress alarm output contacts.
• Opto-Electronic System Sensor: Featuring a concealed optical sensor unaffected by wind, warpage or door sag.
• Holding Force: 1500 Lbs. high security holding force (holding force not evaluated by UL) effectively deters forced access or egress.
• Lifetime Warranty - American Made in the USA by DynaLock, with over 20 years experience in the manufacture of electromagnetic locks

DynaLock 3121C2-G2 – Frequently Asked Questions

1) What power supply do I need for a DynaLock 3121C delayed egress pair?
Power input is auto-sensing 12 or 24 VDC/VAC, so one supply covers either. Budget for the pair's draw: 849 mA at 12VDC or 480 mA at 24VDC for the 3121C2. DynaLock notes no special power supply is required, and the system does not need electrified exit devices, electric hinges or door cords.
2) How does the delayed egress sequence actually work on the 3121C?
Door stays latched by the existing mechanical hardware and magnetically held by the lock. When someone unlatches and pushes, the delay timer starts: the audible and red LED pulse for 15 seconds, field selectable to 30. After the delay the magnet releases, the audible goes continuous and the LED turns green until the door is shut and the lock reset. Reset and bypass are done with the built-in keyswitch or a remote signal.
3) Will the doors unlock automatically on a fire alarm?
Yes. Tie the lock into the building fire alarm and the system unlocks automatically, and it also releases whenever power is removed. The fire alarm contacts on the 3101C/3121C are field selectable for normally open or normally closed signals, so it will match whatever the panel provides.
4) If I only need a plain mag lock on a pair of doors and not delayed egress, what should I look at instead?
Delayed egress adds the timer, audible, keyswitch reset and egress sensing, and costs you calibration time on site. For straight magnetic holding on a pair, the Dorma EML320 is a double door electromagnetic lock at 1500 lb, fail safe (electrically locked), and the Alarm Controls 1200D Series is a double door magnetic lock as well. If it is delayed egress you need but on a single leaf, the Alarm Controls 1200DE is the single door delayed egress unit.
5) What is the closest delayed egress alternative to the DynaLock 3121C2-G2 for a single door?
For a single opening, the Alarm Controls 1200DE is a delayed egress magnetic lock built for a single door. The DynaLock 3121C2-G2 is a tandem pair configured for a double outswinging door with a center mullion, using two 11-inch magnets in a master/slave arrangement. If the opening is one leaf rather than a pair, the 1200DE covers the delayed egress function without the second coil.
6) My opening is a sliding door - does the DynaLock 3121C2-G2 work there?
No. The DynaLock 3121C2-G2 is configured for a double outswinging door with a center mullion and mounts under the frame header. For a sliding opening, the Schlage 320M is a compact mortise sliding door electromagnetic lock rated 1500 lbs. holding force, the same force class as the DynaLock.
7) Does the 3121C delayed egress lock need to be handed left or right?
No handing to specify. The delay egress line is non-handed and surface mounted, covering outswing single or double doors and inswing single doors. On the 3121C2 both magnets mount under the header, so you order the same part regardless of which way the leaves swing open.
8) Do I need an external access control panel to run this delayed egress lock?
No. A microprocessor on board manages all lock functions without an external system controller, and DynaLock offers custom factory programs for applications with particular local code requirements. That keeps the wiring to power, fire alarm and whatever monitoring contacts you specified.
9) Will door sag or a warped leaf cause nuisance trips on this delayed egress system?
The egress sensing is an opto-electronic concealed optical sensor that DynaLock states is unaffected by wind, warpage or door sag. Calibration is done with a micrometer style adjustment wheel, so the installer can dial in the sensor on site rather than shimming hardware.
10) What is a lower holding force option than the DynaLock 3121C2-G2 for an interior door?
The Schlage M420 is a 500 lb. single door electromagnetic lock, and the Dortronics 1107 is a narrow 2-inch slim line 600 lb. single door mag lock. Both come in well under the 1500 lbs. of the DynaLock 3121C2-G2 and suit lighter interior openings where the delayed egress function and double-leaf coverage are not required.
11) Is a shear lock like the ROFU 8031-002 a substitute for the DynaLock 3121C2-G2?
It is a different mounting concept. The ROFU 8031-002 is a shear lock with 2200 lb. holding force, 12/24VDC, monitored, and is concealed in the frame and door rather than surface applied. The DynaLock 3121C2-G2 is a surface mounted pair of 11-inch magnets under the header with delayed egress timing, audible, LED status and fire alarm release. A shear lock does not provide the delayed egress sequence.
12) I need door position monitoring on a single 1500 lb. opening - what compares to the DynaLock 3121C2-G2?
The Dorma EML310 DP is a single door 1500 lb. electromagnetic lock with a door position sensor, and the EML310 BA DP version adds a bond alert; both are fire rated and electrically locked (fail safe). The DynaLock 3121C2-G2 also offers a door status switch and a bypass monitor as ordering options, but it is built as a tandem pair for a double outswing opening rather than a single leaf.
13) What finish does the DynaLock 3121C2-G2 come in?
628 satin aluminum (US28), with the Generation 2 redesigned polymer housing cover and LED status indicator. It is a commercial duty product, hardwired rather than battery powered.
14) How does the ACSI 3700 Series compare with the DynaLock 3121C2-G2 for an egress-controlled opening?
The ACSI 3710/3711 is a 3700 Series electromagnetic lock and is an alternative to consider on egress-controlled openings. The DynaLock 3121C2-G2 differs in that it carries the delayed egress electronics on board - a 15 second timer field selectable to 30 seconds, pulsing audible and red LED, green LED on release, keyswitch or remote reset, and field selectable NO/NC fire alarm contacts - with no external system controller needed.
