User manual LIFT-MASTER LM21XP

[. . . ] The release device must be powered from 24Vdc received from an approved UL 1481 regulated power supply with battery backup. The devices can be activated via a smoke detector or an alarm relay from the panel's Form C dry contact relay. The release device features include a 10-, 20-, 30- or 60-second delay on alarm, closed door detection capabilities, Form C relay outputs for the transmission of alarm and trouble signals transmitted to the fire alarm control panel, an audible trouble sounder, and diagnostic feedback LEDs. 2 INTRODUCTION AGENCY REQUIREMENTS Installation and testing to factory specifications shall be performed by factory authorized personnel for proper operation in accordance with 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). WARNING To prevent possible SERIOUS INJURY or DEATH: · DO NOT use this device without fuse links installed. · Test every 90 days to assure proper operation of release device.

[. . . ] Observe proper polarity, 3 (+), 4 (­) when attaching to the release device's terminal board. NOTE: Make certain that the factory-installed jumper between terminal positions 5 and 6 remains in place. OR Normally Open "4-Wire, " Class B Style A Initiating Devices Connect wiring from N/O 4-Wire initiating device loop to positions 3 and 4, making sure an end-of-line supervisory resistor (10k ohm @ 1/2 watt) is installed as shown in Figure 4 or 5, depending upon the type of smoke detector being used. Observe proper polarity, 3 (+), 4 (­) when attaching to the release device's terminal board. NOTE: Make certain that the factoryinstalled jumper between terminal positions 5 and 6 remains in place. OR Normally Closed "4-Wire, " Class B Style A Initiating Devices After removing the factory-installed jumper between terminal positions 5 and 6, connect wiring from N/C 4-Wire initiating device loop to positions 5 and 6 (Figure 6). Most commonly, a relay module is used as an interface between the fire alarm control panel and the release device. The relay module must provide Form C dry contacts for connection to the appropriate terminals on the release device (Figure 7). NOTE: When choosing a relay module to activate the release device in an alarm condition, always select one that provides Form C dry contact relays. Do not use any relay module providing or passing any (control) voltage through the contacts into the release device. The passage of voltage through such a relay module into the release device will cause problems with the operation of the device and may damage the device's terminals and/or circuit board. WARNING CAUTION To prevent DAMAGE to the circuit board, ALL connections from terminals 3 through 16 MUST be dry contact type. FIGURE 7 Relay Module 5 Common Red ­ Black Fire Alarm Control Panel 6 Terminal Strip Normally Closed + FIGURE 8 7 Attach to Common on N/O Proximity Switch Attach to N/O Position on Proximity Switch OPTIONAL CONNECTIONS CLOSE DOOR DETECTION OPTION Connect wiring from N/O electrical loop, using a proximity switch or other similar device with dry contacts, to 7 and 8 (Figure 8). The switch should be placed to engage when the door is in the closed position and so that it will toggle states from its N/O condition (switch closed when door is closed) to a closed condition indicating that the door edge has made contact with desired down position. When the switch is closed by contact from the door, the release device will not activate on alarm, thereby eliminating nuisance gravity drops through the inadvertent release of the fusible link assembly. Fail-safe operation is maintained under all operating conditions, and if power is not available to the unit, the fusible link assembly will be released. The proximity switch and the release device MUST be mounted in the same room. RELAY AND TROUBLE OUTPUTS OPTION Connect wiring from the Alarm Relay Outputs (#11 N/C or #13 N/O and #14 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel when the release device is in an alarm state. Connect wiring from the Trouble Relay Outputs (#14 N/C or #16 N/O and #15 Common) to the appropriate inputs on the fire alarm control panel to provide a signal at the panel that the release device is in a trouble state (Figure 9). If these features are desired, coordinate the interconnection between the Release Device and the Fire Alarm Control Panel with the fire alarm installer. 8 Proximity Switch Part No. LM56A FIGURE 9 11 N/C Alarm Relay Output 12 Common Make all necessary connections to the Fire Alarm Panel as required by the project specifications and the Authority Having Jurisdiction 13 N/O Alarm Relay Output 14 N/C Trouble Output 15 Trouble Common 16 N/O Trouble Output 8 WIRING OPTIONAL CONNECTIONS (cont'd) DIP SWITCH SELECTION The release device will provide a factory default delay of 10 seconds (to minimize nuisance alarms) before releasing the fusible link chain upon alarm or power loss. A 4-position DIP Switch found on the PC board within the release device can be used to adjust the length of the delay to one of four preset delays. The optional delay settings are as follows: Delay Setting 1 10 Seconds 20 Seconds 30 Seconds 60 Seconds Off Off On On Switch Position Factory default setting of 10 seconds shown. FIGURE 10 NOTE: Position 4 is unused and should remain in the OFF position. Position 3 is used to select one of the two available voice messages. ON 1 2 3 4 2 Off On Off On 3 Off Off Off Off 4 Off Off Off Off NOTE: Set all DIP switch options before applying power to the system. 9 TESTING TEST PROCEDURES TO BE PERFORMED BY FACTORY AUTHORIZED PERSONNEL ONLY! [. . . ] If lit, indicates that one of the ancillary devices/loops (smoke detector, annunciator, etc. ) is not grounded properly, and a short to earth ground exists. N/O Detector Alarm N/C Detector Trouble Red (LED 5) Red (LED 6) Close Door Detection Ground Fault Green (LED 2) Yellow (LED 7) 11 WARNING MAINTENANCE REQUIREMENTS MAINTENANCE WARNING WARNING The release device has no scheduled maintenance requirements. The unit has been designed and tested for use in dry, indoor locations. Testing of the unit at least once every 90 days is recommended, but test intervals shall ultimately be subject to criteria established by the Authority Having Jurisdiction (AHJ). CAUTION To avoid SERIOUS PERSONAL INJURY or DEATH from electrocution, disconnect ALL power BEFORE performing ANY maintenance. FIGURE 1 Mechanical Reset Plunger Front of Release Device End Link Bottom of Release Device Electronic Reset Button Test Button Red LED (Line Power Present) Yellow LED (Close Door Detection Release Disabled) ENCLOSURE MOUNTED LEDS STATUS INDICATORS LED Label LED Color Disable Yellow Description The Yellow LED will light when the door reaches the close limit and activates a proximity switch attached to terminal positions 7 and 8 on the release device. This configuration results in the device not releasing the fusible link assembly in alarm or power loss situations and should only be used when the fire door is kept in a constant closed position.
