Installation and testing to factory specifications shall be performed by factory authorized personnel for proper operation in
accordance with all of the latest National Fire Protection Association (NFPA), Underwriters Laboratories (UL), National Electrical Code

GENERAL DESCRIPTION

The Fire Sentinel Floor Reset is a factory installed option on the
FSXP-FLR, FSXPBB-FLR and FSXPBBVB-FLR Release Devices.
The reset Mechanism enhances the standard releasing device by
providing a captured end link, which is easily reset from ground
level after a door release by means of a push-pull cable assembly.
The reset mechanism has been designed for use with the Grifco
fire door hoist, and is ideally suited for use on all doors and
shutters requiring frequent testing.

NOTE: This addendum serves as a supplement to the Fire Sentinel
release device manual. Review all installation instructions,
procedures, cautions and warnings contained within this
addendum as well as the unit installation manual prior to
installing and/or servicing this product. As with all release device
systems, maximum fire protection is provided when installed in
accordance with factory specifications and used with fuse link
systems.

Test system regularly to assure proper operation.

INSTALLATION INSTRUCTIONS ADDENDUM

Installation procedures, and door manufacturer instructions, must
be followed to assure performance of the release device/reset
mechanism to factory standards. To be performed by factory
authorized personnel only.

MOUNTING PROCEDURE (Figure 1)

1. The release device shall be mounted on a vertical surface with
chain end link exiting side of enclosure. The unit may be
rotated 90 degrees CW for a direct vertical pull.

2. Secure the release device enclosure with fastener (#10 is the
minimum size recommended). If installing in masonry, use
concrete anchors (not provided).

3. Release device and associated hardware [sash chain or 1/16
cable, eyebolts, fuse links (Do not install this unit without fuse
links), turnbuckles] shall be installed as per door
manufacturers recommendations (Figure 1). End link direction
of pull should be perpendicular to the enclosure side. An
eyebolt installed at a distance of 18" to 24" from the release
device should adequately redirect sash chain.

4. Connect fuse links, sash chain, S-hooks and turnbuckles as
required. Remove sash chain slack by adjusting turnbuckle.

RESET CABLE MOUNTING PROCEDURE (Figure 2)

1. Reset cable mounting box should be mounted with minimum
#6 size fastening screws/bolts for surfaces other than masonry.
For masonry applications use 1/4" or greater anchors or studs
as required for proper mounting strength.

2. Insert cable through knockout and secure with 9/16" jam nut.

3. Make sure release device/reset is in released position
(Figure 3) and cable is fully pushed in with reset handle seated
the against jam nut. Cut cable to length 1-1/4" of cable through
end link slot. Do not exceed a 9" bend radius on 1 x 19 strand
cable. When using solid cable, refer to manufacturer specified
bend radius restrictions. Install wire stop a maximum of 1"
from end of cable. Secure cable at 36" maximum spacing using
suitable 3/16" cable clip or clamp (Figure 3).
