MADE IN THE U.S.A.

RELEASE DEVICE MODEL-RR (REMOTE RELEASE)

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!

SECTION D. TEST PROCEDURES TO BE PERFORMED BY FACTORY AUTHORIZED PERSONNEL ONLY! REGULAR TESTING OF ALL RELEASE DEVICE

EQUIPMENT IS RECOMMENDED. TESTING SHALL BE WITNESSED FOR PROPER OPERATION.

Testing does not affect normal operation of alarm system when connected to release device. Testing and normal operation can only be accomplished with power applied to unit. When power is applied to unit under test the Power LED (red) will be lit on

the bottom of the release device.

CLEAR FIRE DOOR OPENING AND PROHIBIT ALL TRAFFIC THROUGH DOOR OPENING DURING TESTING OF SYSTEM!

Door must be in open position with power applied to unit and/or master unit on Daisy chain configurations.

A.) Stand alone use LM90-RR.

1. Depress test button on side of release device (figure 1). LM90 release device will immediately release door. Release test button.

2. Reset and raise door. 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 reset. Allow a minimum of 25 seconds between tests of release device.

B.) Stand alone use LM90-RRD (Delayed unit)

1. Depress and continue to hold test button on side of release device (figure 1). After 10 sec. (+/- 2 sec.) delay unit

will release door. Release test button.

2. Reset and raise door. 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 reset. Allow a minimum of 25 seconds between tests of release device.

C.) Daisy Chain use. Model LM90-RR only.

1. Depress and continue to hold chassis mount test button on master unit. After 10 second delay (factory adjusted) all Remote Releases will close simultaneously. Reset as described above.

Allow a minimum of 25 seconds between tests of release device.

After completing all tests, make sure door is in its normally open position and all power required for normal operation is restored to unit. This unit is designed to operate with power applied.

REMINDER: Testing of the "LM90-RR" release device is independent of, and shall in no way be interpreted as an alternative method of, testing of the fire alarm system, motorized operator and/or any other system component employed on the fire door or counter fire door installation. TESTING SHALL BE PERFORMED AND WITNESSED FOR PROPER OPERATION.

MAINTENANCE REQUIREMENTS

The Remote Release Devices have no scheduled maintenance requirements. The unit has been designed and tested for use in indoor locations. Regular testing of the unit is recommended. Testing should be performed a minimum of once annually as per appropriate standards, but test intervals shall ultimately be subject to criteria established by the Final Authority Having Jurisdiction (AHJ).

Should servicing of equipment be required, personnel authorized to perform such maintenance shall ensure that; a) all traffic is prohibited through door opening, b) door is mechanically released and fully closed, c) all power is disconnected from unit. After servicing equipment as required, unit shall be tested and witnessed for proper operation as described in SECTION D- TEST

PROCEDURES, contained herein.
