U.L. LISTED CANADIAN LISTED CSFM: 7300-1418:100

GENERAL DESCRIPTION: S/N__________________

The RR Release Devices are fail-safe and designed for use on rolling doors, single-slide and center parting level and inclined
track doors, fire dampers and self closing windows. All models are normally energized and incorporate transient /overvoltage
protection, a manual test feature and an easy reset, vibration resistant latching mechanism. The Model-RR Release Device
responds to emergency conditions generated by manual or automatic normally closed initiating devices and shall be used in
conjunction with a fuse link system. The Release Device is available in fixed and adjustable time delay options, Models RR
and RRD.

CAUTION: Review all installation instructions, procedures, cautions and warnings contained within this manual prior to
installing and/or servicing this product. As with all releasing device systems, maximum fire protection is provided when
installed in accordance with factory specifications and used with fuse link systems.

Fail-safe operation can only be provided with input power applied.

TEST SYSTEM REGULARLY TO ASSURE PROPER OPERATION.

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 (NEC), local, state, county, district and/or other
applicable building and fire standards, guidelines, regulations and codes including, but not limited to, all
appendices and amendments and the requirements of the local authority having jurisdiction (AHJ).

INSTALLATION INSTRUCTIONS - To be performed by factory authorized personnel only.

The following installation procedures must be followed to assure performance of the release device to factory standards. All
hardware, fusible links and chain or cable shall be furnished by door manufacturer or installing company and shall be
approved or recognized as required for use with this product.

SECTION A. MOUNTING PROCEDURE (Figures 1 & 1A)

1. The release device shall be mounted on a vertical surface with chain end link exiting side of enclosure as illustrated in
figure 1 (horizontal pull) or 1A (vertical pull).

2. Release device enclosure shall be mounted with minimum #10 size fastening screws or bolts for securing to structures
other than masonry. Masonry applications shall utilize 1/4" or greater anchors or studs as required to insure proper
mounting strength.

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 manufacturer recommendations (fig. 1 & 1A typical installation
configura tion). Note should be taken that the end link direction of pull is perpendicular to the enclosure side. An eye bolt
installed at a distance of 18 to 24 inches from the release device should adequately redirect sash chain pull as illustrated
in figures 1 and 1A.

4. Complete hardware installation by connecting fuse links, sash chain, S-hooks and turnbuckles as required. Reset release
device by depressing reset knob in until latch clicks into locking position Push end link into opening of release
mechanism while holding tension from release arm. Release rest knob. Release device is now set.

SECTION B. Smoke Detectors.

When installing smoke detectors with this unit refer to NFPA 72 and NFPA 80, for instructions concerning proper

placement and detection coverage.

SECTION C. ELECTRICAL CONNECTIONS

All models (Figure 3- stand alone, Figure 3A- Delayed Daisy Chain) Installation of all wiring and connections shall be
performed in accordance with, but not limited to, the latest NFPA, UL and NEC standards. In addition, all installations subject
to Canadian standards shall be performed in accordance with the Canadian Electrical Code, Part I, with respect to wiring
material, wiring gauge related to power capacity requirements and circuit length and wiring methods.

I) Stand alone use (Figure 3) The model-RR Release Device, does not provide delay in power loss or alarm. Use Model

RRD if the installation is stand alone and a delay is required

1. Turn off power supply before beginning.

2. Verify voltage rating of release device to power source being utilized.

3. Connect power source inputs (through normally closed initiating device) to red (+) and black (-) wires. Observe proper
polarity. Install chassis ground where applicable. Do not connect (-) to chassis ground.

II) Delayed Daisy Chain -LM90 Series Model LM90-B2 Master. Daisy chain configuration provides time delay feature from

master unit (Model B2 Master). Independent delays are set inside master unit there is a 10 second alarm (factory set) and
battery support for power loss. Use only the LM90-RR in daisy chain configuration to avoid doubling the time delay. DO
NOT use the LM90-RR-24 when using the Daisy Chain configuration.

1) Run two wires (18 gauge) from master unit to first LM90-RR-12. Run two wires (18 gauge) between each Remote.
Maximum of three (3) units.

2) Connect red (+) wire from LM90-RR-12 to wiring from TB1-15 and black wire to wiring from TB2-1. Review Figure 3A for
additional wiring required inside of master unit.

Verify connections made within unit. Close cover and secure screw-on lid after all connections are made.

DO NOT LEAVE COVER OPEN AFTER CONNECTIONS ARE MADE!
