IMPORTANT NOTES - READ BEFORE INSTALLING

• 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 plug 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 device.
• A double door application consists of two LBR devices and one auxiliary fire latch. The auxiliary fire latch is only for use with the Hager 4500 Series LBR and CLB devices. The 4500 Series LBR device comes with a standard top latch strike (4923F), which must be utilized to maintain fire listing. The 4500C Series CLB device comes with a standard top latch strike (4945F) which must be utilized to maintain fire listing.
• Refer to the 4500 SVR/LBR Installation Instructions (I-ED00792) or the 4500 CVR/LBR Installation Instructions (I-ED01285) for further details on the 4500 Series LBR devices.

STEP 3: INSTALL AUXILIARY FIRE LATCH

• A. Insert latch and use the provided screws to secure latch.

• B. Self adjusting tabs on the hole plug will lock in place to secure the plug.

STEP 5: REVIEW INSTALLATION

• A. Close both doors and verify auxiliary fire latch and strike hole are lined up.
• B. Be sure the door gap directly in front of the auxiliary fire latch is not covered with a door edge guard or any other similar type device.
