User manual LIFT-MASTER LM90 MODEL B2

[. . . ] Use only hardware approved or recognized by the appropriate testing or listing agencies in conjunction with the installation of this product. The release device shall be mounted on a vertical surface with chain end link exiting side of enclosure as illustrated in figure 1. 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. * TYPICAL INSTALLATION END LINK FIGURE 1 LM90-B2 RELEASE DEVICE/ CONTROL PANEL TURNBUCKLE FUSE LINK FUSE LINKS MOTOR OPTIONAL REMOTE TEST PLATE OPTIONAL ANNUNCIATOR * Actual configuration may differ. [. . . ] When motor control secondary voltage is present (24V-30V AC or dc) the release device logic will prevent the solenoid from energizing on alarm, thereby allowing the motor to drive the door closed by activation from the automated fire alarm signaling source through the operator. CAUTION: The automated signaling source and/or the motor operator shall contain logic capable of determining whether the door has fully closed upon activation. In absence of full closure, the motor control voltage shall be interrupted to release device allowing for release device initiated closure. CAUTION: "DO NOT" use this option on non-automated installations where door closings through the motor can only be initiated manually . *DOOR EDGE (Down limit detection) This option interfaces to electrical contact type lower limit sensing devices and/or magnetic proximity type switches and must be used when the "motor voltage" option is used. If the electrical contact has toggled states from its N/C condition (switch closed when door is "NOT" at lower limit) indicating the door edge has made contact with desired down position, the release device logic will prevent the solenoid from energizing on alarm, thereby eliminating any damage which may result to the door from the release device attempting to close the already lowered door. Connect motor control sensing voltage (24-30V, AC or DC) from motor controller transformer secondary to TB3 screws 1 (+) & 2 (-) Observe proper polarity with DC control voltages. 4 Electrical Connections continued * 6. Lower limit switch. Connect wiring from N/O electrical loop (switch open when door is up) to TB1 screws 1 & 16 or N/O electrical loop (switch closed with door up) to TB1-1 & 18. * 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. Annunciator - (+12VDC output) connect annunciator (option) observing polarity to TB1-6 (-) & 7 (+). Relay outputs - Two separate SPDT dry contact relay outputs are provided for switching of devices external to the release device. A non-delayed output (relay toggles on alarm- beginning of time delay) is provided on TB110, 11 &12 and a delayed relay output (relay toggles after time delay) is provided on TB1-14, 15 &17. Note: Battery should "not" be connected until testing of unit is being performed! TESTING OF RELEASE DEVICE/CONTROL PANEL SHALL BE PERFORMED AND WITNESSED FOR NORMAL OPERATION AFTER INSTALLATION. REFER TO TEST PROCEDURES CONTAINED HEREIN, AS WELL AS ANY OTHER TESTING PROGRAMS RECOMMENDED BY DOOR MANUFACTURER.
