User manual LIFT-MASTER LM90 MODEL B2

[. . . ] LISTED GENERAL DESCRIPTION CANADIAN LISTED CSFM: 7300-1418:100 S/N:________________ The B2 Series Time Delay Release Devices are UL Listed, Canadian Listed, and CSFM Listed for use on rolling doors, single-slide and center parting level and inclined track doors. All models are normally energized Fail-Safe Releasing Devices incorporating an internal 72 hour battery pack and state of the art electronic control circuitry. The Release Devices respond to emergency conditions generated by manual or automatic normally closed initiating devices and shall be used in conjunction with a temperature fuse link system. The Release Device features include separate adjustable time delays for alarm and power loss, up to 72 hours battery support for release and smoke detectors, motor voltage sensing, form-C relay outputs, proximity/down limit detection, annunciator outputs with voice module options and trouble diagnostic capabilities. [. . . ] 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 (+). If voice option is included see LM21-VAS, Installation Manual. Do Not connect a speaker to this output. 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. See Figure 2 for contact status and ratings. 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.
