LBR DEVICE NOTES

LBR devices require the following additional components to maintain fire rating:

  • One Fire Bolt per pair of doors is required P/N 2-649-0166
  • Head Cover Hole Plug P/N 26490167

Important Fire Listing Notes: READ THIS FIRST!

  • Fire rated devices must be ordered and installed in pairs of vertical rod devices or can be used in conjunction with an approved automatic or constant latching flush bolt.
  • The auxiliary fire latch will keep the doors in alignment during a fire when the bolt extends from the auxiliary fire latch into the strike hole in the opposite door. For the auxiliary fire latch bolt to extend into the strike hole, the black cap visible on the face of the auxiliary fire latch and the strike hole must melt. Therefore, do not cover the door gap directly in front of the auxiliary fire latch with a door edge guard or any other similar type of device.

• A double door application consists of two LBR devices and one auxiliary fire latch. The auxiliary fire latch should be installed in the inactive door to maintain fire listing.

  • The auxiliary fire latch is only for use with the Hager 4500 Series LBR devices. The 4500 Series LBR device comes with a standard top latch strike (4923F), which must be utilized to maintain fire listing.
  • Refer to the Auxiliary Fire Latch Installation Instructions (I-ED00863) for further details.

13. ADJUST AND TEST INSTALLATION

EXIT DEVICE OPERATION

When push bar is depressed and the door is opened, the top and bottom latches should be held retracted until door closes. When the push bar is released both latches remain in the retracted state. When the door closes and the top latch engages with the top strike, it releases the holding mechanism and allows the bottom latch to fully extend.

If the latches do not work smoothly when opening and closing the door, adjust the rod accordingly:

Problem Try This
If the bottom latch does not clear the strike or threshold Disconnect the bottom rod from the actuating block and thread
the rod farther into the bottom latch. This will raise the rod
further when the device is activated, retracting the latch bolt
farther, locking it into the latched position.
If the top latch does not clear the strike Disconnect the top rod from the actuating block and thread the
rod into the latch, which will shorten the overall distance. This
will allow the top latch to completely retract out of the way of
the strike, locking into the latched position.
If the top latch does not operate smoothly Perform the steps noted above. Also try threading the rod into
the latch farther if required.
If the latches are not staying retracted when the door is
opened 		The top latch may be too far away from the top strike. Insert
one top strike shim underneath the top strike to move it closer
to the latch and test operation.
If the problem continues, insert the second provided shims
underneath the top strike

14. INSTALL COVERS

Install chassis head cover and both top and bottom latch covers.

Install Head Cover Plug (FOR LBR DEVICES ONLY):

STEP 1 : Slide the head cover plug into the bottom slot on the exit device head cover. Since the LBR does not use a bottom rod, the hole plug will block off this hole from debris or tampering.

Rev 10, Rev Date: 12/12/2024 Page 11 of 13

15. INSTALL ROD GUIDES

Install top and bottom rod guides centered between latch cover and head cover or at desired height. SCREWS: Metal Door: 8-32 machine screws (4) Wood Door: #10 wood screws (4)

16. DOGGING DEVICE

For increasing the life of this device, dog device during high traffic periods of the day. (A dogging device is not available on fire rated models).

Hex Wrench Dogging:

  • Engage Dogging: Depress push bar, then insert dogging hex wrench and turn clockwise 35°. The push bar will remain depressed and the latch will stay retracted.
  • Release Dogging: Hold push bar, insert dogging hex wrench and turn counterclockwise 35°. The push bar will return to the up position and latch will extend to lock door.

Cylinder Dogging:

For cylinder dogging, remove the cover plate. Remove the hex wrench extension located below the dogging cover plate, which is held in place by a magnet. Install a mortise cylinder into the cylinder dogging cover plate using an 11/32" [8.7] solid cylinder collar and cash box nut. On the mortise cylinder, use a "standard cam" (.723" [18], screw center to tip of cam). The cylinder should be oriented so the cam is pointing away from the exit device push bar. Install the dogging cover plate with cylinder and test dogging. Depress the push bar, insert key, and turn the key clockwise to dog device.

Required Hardware for cylinder dogging:

  • Mortise Cylinder with Standard Straight Cam (1)
    • Cylinder Lengths: 1 1/8", 1 1/4", or 1 3/8"
    • Cam center to tip: 0.723" [18]
  • Hager Cylinder Dogging Kit (No. 4926) (1)
    • Dogging Cover Plate with Plastic Insert, Spring clip, & Cylinder Dogging Lock Plate (1)
    • Solid Cylinder Collar (1)
      • 11/32" [7.8] high
    • Cash Box Nut (1)

If it is difficult to dog the device properly, disconnect the top rod from the actuating block and rotate the rod counterclockwise which will lengthen the overall distance. This will allow the push bar to be fully depressed which allows the dogging mechanism to securely attach. If this does not work, repeat the same step with the bottom rod.
