AUXILIARY
FIRE LATCH
P/N 26490166
LBR devices require the following additional components:
•
Head Cover Hole Plug – P/N 26490167
•
Auxiliary Fire Latch – P/N 26490166 (Required for Fire Doors)
Important 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
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 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.
