Use dimensions shown on page 5 provided to locate attaching screws on frame and door. Prepare holes 3/4" Conduit (By others) Terminal Strips On/Off Switch Closer/Holder Backplate For concealed wire applications only Locate and drill 1-1/8" diameter hole in the frame face for 3/4" conduit. (This is normally done at the time the frame is being installed.) Connect conduit to backplate before fastening backplate to frame 2. Attach backplate/closer assembly to frame. Position backplate end with terminal strips away from hinge edge of frame 3. Make electrical connections: A) 12-2960: Select and follow the wiring diagram from wiring instructions sheet A7408 and 'Checkout Procedure' from Page 3. B) 9-2960: Make solenoid wire connections with power input wires from 12-2960 using two wire nuts provided in screw pack. Select proper wiring diagram and 'Checkout Procedure' from Page 3.

NOTE: If electrical connections are to be made at a later date, place cover on chassis now to prevent its loss, see Step F. 5. Installation of arm on closer: With appropriate size wrench, rotate closer top spindle approximately 45ϒ (see step C below) (NOTE: Closing both valves for door speed and latching speed makes this procedure much easier). Position closer arm on bottom spindle approximately parallel to the door and arm length away from hinge. Secure arm with screw and washer 2960 6. Installation of track on door: Remove end cap from track. Position track with open side up. Insert roller end of closer arm in sliding groove of track. With arm engaged in slide groove, slide track, into position so that prepared holes on door align with track holes Replace end cap and secure track to door 9-2960 Companion unit (without electronics) not shown C Position of Arms and Index Settings View Looking Up When Assembling Arm to Spindle Approximate Preload Rigid Arm Track View Looking Up When Assembling Arm to Spindle Track Screw (2 Reqd) Position of Main Arm When Assembled to Spindle Index Right Hand Door Left Hand Door Mark on Index Spindle Mark on Spindle 1 A7395C
D Adjust Spring Power According to Chart 5/8 " Adjustment Nut Clockwise Turns of Adjusting Nut 8 8 12 16 Maximum adjustment is approximately 20 turns. Do not forcibly extend adjustment beyond limits. Turn the spring adjusting nut clockwise the required number of turns to match door width as indicated in chart. Where strong drafts exist, increase spring power as needed. 351 Series door closers leave the factory with the spring adjustment set at eight (8) turns E Adjustment Instructions Minimum recommended door closing time is 6 seconds for doors opened to 90 degrees. Use 1/8" hex (Allen) wrench to adjust valves as needed. Closing and latching speeds: Turn valves clockwise to slow down or counterclockwise to speed up door movement. Backcheck: To regulate the intensity of backcheck action, turn valve clockwise to increase or counterclockwise to decrease checking. Caution: Set valve for slight cushioning effect. Closer can be damaged if the checking action is too abrupt. Never use the backcheck as a door stop. Always use a door stop to stop the door.

Checkout Procedure for both 12- and 9- units 1. Turn the power to the unit On. Red LED pilot light should illuminate at 8 sec. intervals 2. Open door to the hold open point. The door should hold open. Manually pull door out of hold open and release. Door should close 3. Open door to the hold open position. Depress (maintained type) On/Off test switch button on the power supply board. Door should close 4. Depress On/Off test switch again. Open door to the hold open position. Introducing smoke into the smoke detector chamber assembly will bring the unit into alarm. The red LED will be continuously illuminated and the door will close. After clearing the smoke chamber, reset unit per instructions below Resetting Instructions 1. Remote Reset: Cycle main power by turning the facility main power supply OFF then ON. NOTE: If there are other units connected to the same power supply, those doors will close. They will have to be reopened returning them to the hold open position 2. Local Reset: Insert a small flat head screwdriver through the cover and into the slotted light tube on the smoke detector as shown. Turn screwdriver slightly (about 1/8 turn) clockwise until hitting stop and hold for 2 seconds until the Red LED turns OFF WARNING: Do not force past the stop. Doing so may damage the smoke detector Once the detector is reset and the smoke has cleared, the detector s Red LED should flash once every 8 seconds. The door(s) should hold open now Smoke Detector Maintenance SARGENT recommends cleaning smoke detectors at least every six months. The frequency of cleaning will depend upon local ambient conditions The smoke detector in this door closer-holder has been enhanced with a feature that detects when a smoke-sensing chamber requires cleaning due to dirt and dust. The need for cleaning is indicated by the flashing of the Red LED light once per second Normal Supervisory Operation Red LED flashes once every 8 seconds Dirty Chamber needs cleaning Red LED flashes once every second Smoke Detection Red LED is continuously illuminated To clean the smoke detector assembly, follow the instructions below: NOTE: Before servicing the system, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of service. Disable the zone undergoing maintenance to prevent unwanted alarms Chamber Cover and screen Slot for screwdriver To remove cover Slotted light tube (Red LED) RP1 test point RP2 test point Remove detector cover and screen assembly using a standard screwdriver. Turn the screwdriver in the cover slot to loosen the cover and carefully rock the cover back and forth until it snaps out of place. See slot location above Inspect chamber for particles and dust. Vacuum the screen, cover, and photo chamber. Then, use clean compressed air to loosen and blow out any remaining debris Before reassembling the detector, be sure all parts are free of dust and debris Replace cover and screen, aligning cover snaps, press cover onto chamber until it snaps into place Measure and record the test voltage at test points RP1 and RP2 (see above). If the smoke detector is operating normally and was cleaned effectively, the test voltage will be greater than.90vdc and less than 1.58VDC. The test voltage will increase with dust accumulation in the smoke sensing chamber. A difference in test voltages over time will provide an indication of dust accumulation Enable system and inform proper authorities that system is operational A7395C 4
