Technical Data Sheet Motorized Fire Vents Operating Instructions Motorized units This is a motorized fire vent that has been test operated at the factory. Prior to electrical hookup, the cover may be opened manually by removing the shipping wire. Use care since the cover is spring-loaded and will open by itself when released. During construction, the cover may be closed manually and tied closed temporarily with wire or rope until the electrician arrives. Do not detach the cable of disturb in any way the relationship between the cable and the cable drum as this affects the limit switch adjustment. The limit switches have been factory set and normally should not need field adjustments. After the electrician provides power to the motor operator, push the CLOSE button. The cable drum must rotate clockwise to close. If the cable drum rotates counterclockwise when the CLOSE button is activated, then push the STOP button immediately and reverse the power. See enclosed wiring diagram. (Osco 2600-377 Rev. Q). With the cable drum rotating in the proper direction, check to be sure the covers close down firmly onto the frame and that the motor operator automatically shuts itself off. If the cover does not close all the way, or if the motor continues to run with the cover closed, push the STOP button and adjust the CLOSE limit switch. In the same manner, check the OPEN limit switch adjustment. In the event of a fire, the fusible link will release the cable from the cover and the cover will open. To reattach the cable to the cover, first be sure the motor operation is in the open position and the cable unwound from the drum. Then attach the cable to the cover using a new fusible link. Push the CLOSE button and recheck the limit switch adjustment described above. An inside manual release pull cable has been provided for emergency use only. After use, check to be sure clutch pins re-engage and recheck limit switch setting. The motor operator is also equipped with a 24 VDC relay for use with a fire control system. When an electrical signal is received by the relay, the motor rotates the drum allowing the cable to unwind to the open position. To close the covers, push the CLOSE button on the 3 Push Button remote included with the vent. MOTOR-INST 4/30/10
Technical Data Sheet Instructions for Motorized Roof Scuttles & Sidewalk Door To attach motor to unit: 1. Attach lower end of motor to bracket on the frame using clevis pin, cotter pin, and spacers provided (as shown in Fig. 1 & 1a). NOTE: Wired end of motor must be oriented so that wires are directed toward the junction box (as shown in Fig. 2). Figure 1 Figure 1a Figure 2 MOTOR inst 4 10/8/14
Technical Data Sheet Instructions for Motorized Roof Scuttles & Sidewalk Door 2. Attach upper end of motor shaft to bracket on the cover in the same manner as above. Cover may have to be maneuvered in open position in order to properly locate shaft. Shaft may be rotated manually, but not raised or lowered. NOTE: This step may require 2 assemblers. 3. Repeat above steps for second motor (double leaf doors only). 4. Ensure that cotter pins are secure and motor is solidly in place before wiring. To wire unit to control panel: 1. Wire unit according to the diagrams shown for single leaf (Fig. 3) or double leaf (fig. 4). Additional wiring information is included inside the control box. (10-wire cable minimum required for single leaf, 14-wire cable minimum required for double leaf). Figure 3 MOTOR inst 4 10/8/14
Technical Data Sheet Instructions for Motorized Roof Scuttles & Sidewalk Door Figure 4 2. Check operation of all components. Adjust limit switches if necessary. a. Push OPEN button to see that cover(s) moves toward the open position. If the cover(s) moves toward the closed position, push the STOP button immediately. To correct, reverse the leads in terminals 5&6 (for single leaf) or in terminals 7&8 and 9&10 (for double leaf). These terminals are on the junction box. b. Limit switches are factory set and should not need to be adjusted. However, if adjustment is necessary, switches are easily adjustable by loosening the setscrew (front/center of switch) and sliding the arm up or down, then tightening the screw when switch is properly adjusted. If unit is opened and the motor does not cease operation at the full open position, press the STOP button and adjust the open limit switch (located at the hinge side) by sliding the arm slightly downward. The switch should pivot when the cover is fully open. If unit is closed and the motor does not cease operation, press the STOP button and adjust the close limit switch upward. Lastly, if the unit is closed but the motor ceases operation before the unit is fully closed, the close switch must be adjusted downward. It is imperative (to prevent damage) that the cover(s) moves in the direction of the button pushed. MOTOR inst 4 10/8/14
