RELEASE DEVICE MODEL C INSTALLATION MANUAL

UL LISTED CANADIAN LISTED CSFM: 7300-1418:100

GENERAL DESCRIPTION: S/N________________________

The LM90-C Release Device/Control Panel is a U.L. Listed, Canadian Listed (C-UL) and California State Fire Marshal Listed (CSFM) normally energized Fail-Safe device with state of the art electronic control circuitry. This device is designed for use with motorized doors incorporating a reversing feature safety edge to create an automated door closing system. “DO NOT” install this unit without a safety edge.

The LM90-C high performance control panel responds to emergency conditions generated by manual or automatic initiating devices. Upon activation from such a device, the unit can provide a voice warning (option) indicating that a closure is about to occur and will then close the door through the motor. If the alarm is still present and power is available to the operator, the door can be opened by depressing the open switch of the operator, after which the door will close again. If the door meets an obstruction while in alarm, the door will reverse and make three attempts to close, after which the motor will be shut off and the release mechanism will release the door onto the obstruction. The unit can be factory ordered with cycle count from 1 through 10 (3 count standard), as well as continuous cycling capability. A safety timer within the unit will turn the motor off and perform a mechanical release if the lower limit is not detected within a predetermined time period. Verify factory installed options to desired features.

The Release Device features include time delay on alarm, remote test, motor voltage sensing, form-C output, lower limit detection, safety timer, battery support for release device logic, smoke detectors, multilingual voice (option), standard annunciators and trouble diagnostic capabilities (does not support motor). Check model label on unit to be installed to verify operating voltage.

CAUTION: Review all installation instructions, procedures, referenced publications, 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. “DO NOT” install this unit without a fuse link system.

NOT exceed maximum pull rating of 40 lbs. on releasing device.

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. See Electrical Connections page 5 for wiring information. End of Line Devices shall be installed for supervision of electrical power to smoke detector. “DO NOT” interface this unit to smoke detectors if electrical supervision is

not provided by means of an End-of-Line Device used in conjunction with the Model C!

C. ELECTRICAL CONNECTIONS

Installation of all wiring and connections, including Class 1 and Class 2 circuits, shall be performed in accordance with, but not limited to, the latest NFPA, UL and NEC standards and codes. 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 type, wiring gauge related to power capacity requirements and circuit length and wiring methods. This unit is designed to be used on motorized doors incorporating a reversing feature safety edge. DO NOT use this unit on a motorized door if a safety edge has not been installed. SEE Figure 2 - Verify wiring configuration with that recommended by door manufacturer for use of this product with specific door and accessories being utilized. All wiring beginning at step 4 is low voltage. 18 gauge wire is recommended.

1. Turn off power supply sources for Model C as well as motor before beginning.

2. Verify voltage rating of release device/control panel to power source. Model voltage is indicated on side of unit.

3. Connect power source inputs to TB5, screws 1 & 2. On 24VDC units observe proper polarity by placing positive (+) wire to screw 1. TB5 screw 3 shall be utilized for earth ground where applicable. (DO NOT connect battery)

4. (a) Normally closed initiating devices - remove jumper from TB1 screw 2 & 3. Connect wiring from N/C initiating device loop to TB1 screws 2 & 3. Auxiliary power (+12VDC) for smoke detectors may be obtained from TB2. Observe proper polarity, TB2-2 (+), TB2-1 (-). 4 detector maximum. (b) Normally open initiating devices - (The N/C & N/O loops may be used simultaneously, but if the N/C loop is "NOT” used, make sure jumper is installed across TB1 screws 2 & 3). Connect wiring from N/O initiating device loop to TB1 screws 4 & 5 (do not share loop with other alarm circuits), making sure end of line supervisory resistor (51 Kohm @ 1/4 Watt) is installed at end of line as indicated. Auxiliary power (+12VDC) for smoke detectors may be obtained from TB2. Observe proper polarity, TB2-2 (+),TB2-1 (-). 4 detector maximum.

Note: TB1 initiating device loops are supervised and cannot be directly series or paralleled between multiple release devices or shared with other alarm equipment. For proper wiring configurations for multiple smoke detectors or signalling for simultaneous closure on multiple doors call tech support. Incorrect wiring between units may cause damage to the release control circuit and void warranty.

5. Connect motor control sensing voltage (24-30V AC or DC) from motor controller transformer secondary to TB3 screws

1 (+) & 2 (-). This connection must be made or the unit will perform a mechanical release in all alarm conditions.

* 6. (a) Aux. Lower limit switch. Connect wiring from N/C electrical loop (switch closed when door is up) to TB1 screws 1 &

18 "or" N/O electrical loop (switch open with door up) to TB1-1 & 16. This input precludes the door mechanism from releasing if a lower limit is detected (door is already closed). This circuit also turns off sounders in down limit. (b) Aux. Upper limit switch. Connect wiring from N/O electrical loop (switch closed when door is up) to TB1-8 & 9 “or” N/C electrical loop (switch open with door up) to TB1-8 & 13. Connection to an auxiliary up limit switch is required for 3 cycle obstruction count feature.

Set aux. limit to toggle before operator limit when door is traveling toward open position.

Improper adjustment will result in continuous cycling of door.

* Note: Electrical loops must be provided as dry contacts and may not be used in conjunction with the simultaneous

switching of a motor control or any other voltage through the same contacts. Connections of this type will result in immediate damage to the release device.

Jumpers must remain installed on loops not being used.

7. Motor control relay (Delay relay) - Connect wiring from TB1-14 & 17 across motor control down switch (For use with N/O down switch). This relay output latches to initiate a door closure through the operator after a 10 sec. delay.

8. Remote test station. - (option) This option disables the cycle counter to allow testing of the door without a mechanical release after 3 cycles. Connect remote test switch common to TB2-2, N/C to TB4-1 and N/O to TB4-3. Factory jumper should be removed between TB2-2 & TB4-1 when using test switch. Leave jumper in if test plate is not used.
