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 UL 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+ Release device control is in an inactive state and does not interfere with normal operation of the motorized door in its supervisory
(non-alarm) condition. In an alarm condition, the LM90-C+, turns on optional emergency warning appliances, and after the factory set delay, the
operator will be signalled to close. When an obstruction is encountered, the door will reverse to the open position and repeat the attempt to close
two more times. On the third attempt the motor will turn off and the door will rest on the obstruction. Emergency signalling devices will remain
active. If the obstruction is removed, the door will close after a 3 second delay. If the Open button is depressed while the door is resting on the
obstruction, the door will fully open, reset the cycle counter, and fully close, if the obstruction is removed. If the alarm condition is cleared while
the door is resting on the obstruction, the door will fully open and stop. Emergency signalling appliances will turn off and the system will reset. If
no obstruction is encountered during downward travel, the door will close and the warning devices will turn off. The door system remains active
for emergency egress using the Open push button station. Power must be available to the operator in all conditions for the system to operate. In
absence of power to the operator, standard logic incorporated into the battery supported release device, will initiate a mechanical release to close
the door.
The Release Device features include time delay on alarm, remote test, motor voltage sensing, form-C output, lower limit detection, timer,
battery support for release device logic, smoke detectors, multilingual voice (option), standard annunciators and trouble diagnostic capabilities (do 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.
TEST WEEKLY TO ASSURE PROPER OPERATION OF RELEASE DEVICE/CONTROL PANEL
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 equipment to factory standards.
Section A. MOUNTING PROCEDURE (Figure 1)
Typical installation configuration is for illustration only and may not accurately depict door manufacturer’s recommendations.
See door manufacturer’s recommendations for use of this product with specific door being utilized. All hardware required shall
be supplied by the door installer or manufacturer. Use only hardware approved or recognized by the appropriate testing
agencies in conjunction with the installation of this product.
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. See Electrical Connections page 2A 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+.
Section 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 & 2A depicted herein- Verify wiring configuration with that recommended by door manufacturer for use of this
product with specific door operator 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 to power source being utilized. 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. 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.
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 from 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 (24V 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.
Auxiliary Limit Switch - Figure 2A Detail B (Dry contact auxiliary switch required)
* 6. Aux. Open limit switch. Connect wiring from N/O electrical loop (switch closed in open limit) to C+ Module TB2-1&2.
Connection to an auxiliary open 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 loop 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.
7. Operator Closed Limit: (Figure 2A, Closed limit switch Detail A). Remove wire from 24 volt side of operator Close limit
switch. This must be the side of the switch which retains 24 volts when switch opens in down limit position. Splice to
wire from C+ module TB3-1 using wire nut or other suitable connector. Connect return wire from C+ module TB3-2 to
down limit switch.
