INSTALLATION DESCRIPTION

The 3121C and 3121C2 Delay Egress Systems are 1500 pound holding force (holding force not evaluated by UL) per leaf electromagnetic locks, electronically controlled to provide a 15 or 30 second delay in unlocking. The 3121C is one piece, for use on openings without a center mullion. The 3121C2 is two pieces, with a ribbon cable connecting the two, for use on openings with a center mullion. All models have a master/slave configuration, meaning both leafs lock, unlock, and alarm in tandem.

Both models require mechanical and electrical installation procedures as described herein. When completed, a simple adjustment procedure to set door movement will finalize the installation.

HANDLING

The electromagnetic lock and armatures are ruggedly constructed and designed to provide years of trouble-free service. Care must be taken during installation and use, so that the lock faces and armature faces are kept free of dirt, rust, paint, or any other obstruction which may interfere with the lock and armatures making good contact.

MECHANICAL INSTALLATION

Familiarize yourself with the door and frame conditions. Both models must mount rigidly to the underside of the door frame header. The 3121C should be centered on the frame. For the 3121C2, both locks should mount against the center mullion. The door mounted armatures are supplied with hardware that allows them to pivot slightly and pull away from the door as part of the delayed egress function.

NOTES: This lock does not change hands to match the hand of the door. Do not remove the coil assembly from the lock housing. For locks ordered with the DSM2 option, please verify that two magnets are installed inside each of the armature housings.

ELECTRICAL INSTALLATION

After mechanical installation is complete, the lock needs to be wired and adjusted. A continuous power source, 12 or 24 VDC or VAC is required. Once low voltage power is supplied the unit is fully operational. Delay egress systems also normally require fire panel tie-in. All other wiring is for selected options.

NOTE: Please see Egress Sensor Adjustment (page 8) before applying power.

1-877-DynaLock www.dynalock.com INSTALLATION INSTRUCTIONS

MOUNTING CONSIDERATIONS

Inspect the door frame and determine if an angle bracket, spacer or filler plate will be required for installation. The lock will require a 2-9/16" wide header stop for a suitable mounting surface.

*These items are available from DynaLock.

USING THE TEMPLATE

• Fold the template(s) on the dotted line to form a 90 degree angle. Scoring the template(s) with a straight edge and a screwdriver will make it fold easier. 1.
• 3121C: With the doors in the closed and latched positions, place the template against the header and doors, centered on the frame. Tape in place. 2.
  • 3121C2: With the doors in the closed and latched positions, place the templates against the header and doors, with the edges against the center mullion. Be sure to use the correctly handed template for each door. Tape in place.
• Transfer all hole locations to both the doors and header with a center punch, then remove the template(s) from the doors. 3.
• Referring to the template(s), drill four 1/8" dia. lock mounting holes and one or two 9/16" dia. wiring hole(s) in the top of the frame, at the transferred locations. 4.
• Drill the remaining transferred holes in the face of each door to accept the Armature Mounting Plate Assemblies: 5.
  • a. Four 1/8" dia. mounting screw holes, 1" deep.
  • b. One 3/8" dia. armature screw clearance hole, 3/8" deep.
  • c. One 5/16" dia. adjustment wheel screw clearance hole, 1/4" deep.

1-877-DynaLock www.dynalock.com INSTALLATION INSTRUCTIONS

MOUNTING THE ARMATURE ASSEMBLIES

Using the four #10 x 1" flat head sheet metal screws attach the armature mounting plate to the door. Firmly tighten the screws with a #2 phillips screw driver.

Attach the Armature to the Mounting Plate Assembly using the hardware supplied. Apply the supplied thread locking compound to the threads of the Armature Mounting Screw and firmly tighten with a 3/16" hex wrench. The head of the armature mounting screw must not project beyond the face of the armature. Failure to properly secure the Armature to the door could result in serious injury or possible security breach.

Check the installation by pushing in on a corner of the Armature - it should move. Although the mounting screw is tight the Armature should have approximately 1/4" of free play, under slight spring tension.

1-877-DynaLock www.dynalock.com INSTALLATION INSTRUCTIONS

MOUNTING THE LOCK

• Before installation begins remove the rear Electronics Covers, End Covers and Sensor Cover Assemblies (see page 13-15 for parts locations). Carefully unplug the sensor harnesses from the circuit board connectors and detach the Sensor Cover Assemblies from the lock. For 3121C2, carefully remove the ribbon cable. In the upper inside corners of the lock housing(s) are located #1/4- 28 set screws. Using the 1/8" ball head hex wrench loosen (do not remove) the set screws until the Fas-Trak Baseplate(s) is free (Fig. "C"). Remove the Fas-Trak(s). 1.
• Place the Fas-Trak(s) against the header with the slot counter bores visible and the tabs facing the doors (Fig. "A"). Attach the Fas-Trak(s) to the header at the slotted hole locations, with #10 x 1" tek screws or 10-24x1/2" machine screws. Tighten the screws just snug enough to allow for final adjustment. 2.
• Temporarily mount the lock(s) to the Fas-Trak(s) by offsetting the lock(s) 1-1/8" from the jamb (Fig. "C") and tipping the front of the lock(s) down engaging the rear flange of the Fas-Trak(s) (Fig. "B"). Rotate the lock(s) up allowing two tabs (one for 3121C2) to pass through the corresponding notch in the top of the lock housing. Slide the lock(s) into position. Close and latch the doors. Check that the armature and lock faces make full contact. If any adjustment is required gently tap the housing(s) with a soft mallet until full contact is achieved. Open the doors, remove the lock(s) from the Fas-Trak(s) and tighten the slot screws. Drive additional screws into the header using the Fas-Trak(s) as a physical template. Screw heads must not project above the Fas-Trak(s). 3.

Any roughed-in wiring may be brought in at this time through the slotted wiring hole(s) (for 3121B2 include ribbon cable). Re-install the lock on the Fas-Trak(s). Firmly tighten the housing set screws with the 1/8" ball head hex wrench. Re-install the End Covers and Sensor Cover Assemblies. Carefully plug the Sensor harnesses back into the connectors on the circuit boards (see page 13&14). If the lock wiring and set-up are not being done at this time, replace the Electronics Covers and see that these instructions (and ribbon cable for 3121C2) are left 4.

1-877-DynaLock www.dynalock.com INSTALLATION INSTRUCTIONS

BASIC SET-UP

1. Remove the Electronics Cover from the Master Lock (right side) to expose the master circuit board assembly.

- Cover LED 2. L

Bi-color LED, mounted to circuit board housing cover. Displays Red or Green, depending on lock mode (see page 9 for indicator modes). LED is tethered to the J9 circuit board connector, via a 30-wire harness. Should harness become unplugged, observe wire color polarity when reconnecting (see page 13 for further info).

- System Selector Switches 3. C

The selector switches (S3) which control major system functions are factory set to the OFF position for basic lock operation. Switch 1 will be used during sensor adjustment (page 8). Switches 2 through 7 are only used for options described on page 10.

(Factory Setting)

1-877-DynaLock www.dynalock.com INSTALLATION INSTRUCTIONS

BASIC WIRING

Basic hook-up is shown below. For other system features hook-up see "Option Wiring" (page 11).

Terminals 1& 2 - Auto-Sensing Power Input. May be 12 or 24 Volts, AC or DC, uninterrupted. Maximum current draw, by voltage, is as follows:

12V DC: 839mA 12V AC: 1.79A 24V DC: 470mA 24V AC: 1.27A

DO NOT INTERRUPT INPUT POWER (TERMINALS 1 & 2) FOR AUTHORIZED ACCESS/EGRESS. EXTERNAL ACCESS/EGRESS CONTROLS (EX. KEYPAD, CARD READER, ETC.) SHOULD USE DEDICATED BYPASS TERMINALS 7 & 8 or 9 & 10 (SEE PAGE 11).

Terminals 3 & 4 - Fire Panel Input. May be normally-open (N.O.) or normally-closed (N.C.) dry contacts from fire panel (check fire alarm control jumper "FA" - page 6). DO NOT APPLY POWER TO TERMINALS 3 & 4 OR CIRCUIT BOARD DAMAGE WILL OCCUR.

When the fire panel trips, the 3101B will release, the audible will sound a constant tone and the bi-color LED (LED1) will change to green. When the fire panel is reset, the 3101B will reset and lock.

NOTES:

• A power limited, UL Listed power supply for security applications is required for UL294 installations. 1.
• When the 3121C/3121C2 is used with a fire alarm control panel, wiring must be done for fail-safe operation. 2.
• Suitability of all wiring leads is to be determined based on enduser product requirements. 3.

PROPER OPERATION OF THE 3121C/C2 REQUIRES ADJUSTMENT OF THE EGRESS SENSORS PROCEED TO EGRESS SENSOR ADJUSTMENT

1-877-DynaLock www.dynalock.com INSTALLATION INSTRUCTIONS

EGRESS SENSOR ADJUSTMENT

The sensor and armature assemblies are designed for use on doors with existing mechanical latching hardware. If used on doors without latches, false alarms are possible. In these cases, we suggest using external triggers such as our 6451 Exit Sensor Bars - connect using terminals 11&12 and disable the internal sensors (see pages 10&11).

SEE PAGE 10 FOR LOCATION OF ELECTRONIC PARTS MENTIONED IN THIS SECTION

• With both doors closed and latched apply input power to terminals 1 & 2 on Master Lock. Slide selector switch (DS1) #1 to the ON position to activate the Set-Up mode. Rotate the on-board keyswitch counter-clockwise. The lock should now be unlocked (LED1-OFF). 1.
• Open both doors. Temporarily remove the Adjustment Wheel Stops from the Armature Mounting Plates and close the doors. Set aside for re-installation later. 2.
• With the doors closed observe the bi-color LED (LED1) on the circuit board. It should be lit red. If it is not lit, rotate the adjustment wheels counter-clockwise as necessary to ensure that they will contact and fully depress the ball plungers on the lock. Rattle the doors to ensure the LED remains lit. 3.
• With the doors closed and LED1 lit red, unlatch and slowly open either door. The LED will shut off as soon as the door opens far enough for the ball plunger to fully project. Check that the other door operates in the same manner. NOTE: LEDs operate in tandem - both LEDs will go out when either door is opened. 4.

• With adjustment completed, re-install the adjustment wheel stops to lock-in the adjustments. Close the doors, slide selector switch (DS1) #1 back to the OFF position and return the on-board keyswitch to the center position to relock the 3121B/B2. 5.
• Unlatch and push on either door until delay egress triggers (1-3 seconds). The audible will sound and LED1 will flash red. After 15 seconds, both sides of the lock will release. Turn the on-board keyswitch clockwise to reset the lock. If delayed egress triggers too soon, or fails to trigger, re-adjust the sensor adjustment wheel(s) for desired sensitivity. Check that the other door operates in the same manner. 6.
