GENERAL DESCRIPTION

The Fire Door Controller, FDC, is an integrated fire door control system. It is designed to interface with a normally close (NC) or normally open (NO) dr y contact alar m system to control the operation of a fire door. The control station is the standard B2 wiring, momentary contact to open, close and stop, plus wiring for sensing device to reverse and auxiliary devices to open and close with open override.

N OTICE

WARNING

THIS OPERA T OR IS NO T A FIRE ALARM SYSTEM. IT CAN NOT DETECT A FIRE CONDITION.

FUNCTIONAL OPERATION

1. Battery Backup (management system)

The batteries are charged, tested, and monitored automatically by the microprocessor based system. The batteries are tested under load every thirty days, if for any reason the batteries fail this load test, the on board buzzer will sound for 3 seconds of every minute to indicate that the batteries need to be replaced. If the batteries are not replaced within 45 days (from initial test) the door will automatically close, and remain inoperable until the batteries have been replaced. The battery voltage is continuously monitored, if for any reason the voltage drops below 22 VDC (this is the minimum operating voltage for the brake controls) the unit will activate the optional warning signal and automatically close the door.The door will remain inoperable until such time that the batteries come back to charge, or they are replaced.Low batter y condition will be indicated by the on board buzzer sounding 3 seconds out of every minute, and the low battery indicator (located on the key test station) flashing, until the batteries come to the full charge or are replaced.

2. Unit has AC power & no alarm condition:

The B2 control station is used to operate the door electrically. Activation of the safety edge while the door is closing will cause the door to reverse to the full open limit. Activation of the safety edge while the door is opening will NOT effect operation, the door will continue to the open limit. Activating the key-test switch for at least 6 seconds will put the operator in alarm active mode.(see ACTIVE ALARM section for detail operation of alarm active mode)

3. Unit has AC power & active alarm condition (ALARM #1 - smoke alarm etc.):

The unit will activate the OPTIONAL warning signal, the door will automatically close after the preset time delay. (powered down by motor) The time delay is set by means of DIP

switch 1. If the door is in the open position and an alarm condition occurs, the door will automatically close under motor operation. In the event the door should meet an obstruction while closing, it will reverse and return to the full open position, and then start the closing cycle (with delay and warning) again. If the obstruction is not removed, the door will close stopping at the lowest possible position holding the brake for 2 seconds, then releasing the door to Gravity Close (controlled descent). If after the door has finished the cycling mode and the obstruction has been removed, the door will proceed to the floor. In the event of a failure in motor operation, the operator will gravity close.(controlled descent)

FUNCTIONAL OPERATION CONTINUED

4. Unit has AC power & active alarm condition (ALARM #2 - Fire Sensor, thermal sensor etc.):

The unit will activate the optional warning signal, the door will automatically close after the preset time delay.

(powered down by motor) The time delay is set by means of DIP switch 1. If the door is in the open position and the alarm condition occurs, the door will automatically close under motor operation. In the event the door should meet an obstruction while closing, the door will stop for 2 sec onds, then release the door to Gravity Close (controlled descent).After the obstruction has been removed, the door will proceed to the floor. In the event of a failure in motor operation, the operator will gravity close (controlled descent) All control station functions will be rendered inactive in this condition. The safety edge will remain active.

5. Unit has No AC power & No active alarm condition:

The Close and Stop buttons of the B2 control station are functional. The door's descending speed is controlled by the integrated braking system. The door will stop if an obstruction is encountered while closing. The Open button is not functional

6. Unit has No AC power & active alarm condition (Alarm #1 or Alarm #2):

The unit will activate the OPTIONAL warning signal, the door will automatically close after the preset time delay. (controlled by integrated braking system) The time delay is set by means of DIP switch 1. If the door encounters an obstruction while closing , the door will stop on the obstruction, and release the brake after (2) seconds.If the obstruction is then removed the unit will perform a controlled drop of the door.(not powered down by the motor)

7. Activation of the internal Thermal Sensor:

Will activate an alarm #2 switch. With AC power present the unit will react as stated in paragraph 4. With No AC power present the unit will react as stated in paragraph 6.

8. Activation of the Key Test Station:

Key must be activated for 6 seconds The unit will activate the OPTIONAL warning signal, the door will automatically close after the preset time delay. (controlled by integrated braking system) The time delay is set by means of DIP switch

1. (to test the signal devices and the delay time) The door will close using gravity close mode (Controlled Descent) in order to test the door balance, descent speed, and the moment of the door. All sensing devices and control devices will be active. (In order to test these devices)

(See page 5 for procedures)

DOOR SYSTEM TESTING PROCEDURES

Before beginning any testing, secure the door area, keep unauthorized personnel from entering the area during testing. Be sure ac power is present at the operator. (the green "AC" led will be lighted on the operators control board) and that the batteries are connected and fully charged. (the red "DC" led will NOT be lighted on the operators control board)

1. Begin the test with your door at the full "OPEN" position.

2. Make cer tain dip switch #2 is in the "ON" position "FIREDOOR" mode.

3. If your door is equipped with safety photo eyes, make certain dip switch #4 is in the "ON" position.

Note: If 2 minutes total time elapses from the beginning of step #11and the conclusion of step #15, the unit will automatically exit the "TEST" mode.To re-enter the "TEST" mode repeat step #4, and continue testing.

4.Turn the wall mounted key test switch to the "TEST" position and hold for a minimum of 6 seconds. This action simulates an “ALARM” signal.

5. If dip switch #1 is in the "ON" position, the door should begin to close immediately.If dip switch #1 is in the "OFF" position, the door should begin to close after 10 seconds time has elapsed. (the door will not motor down, it will gravity descend)

6. Using a "stop-watch" verify that your door is closing between 6" and 24" per second. (i.e.. A 10ft high door should close in a time between 5 and 20 seconds.) Your door should now be fully closed.

7. Open the door by depressing the "OPEN" button on the three button control station.

8. Repeat step #4.

9.When the door is approximately 3 to4 feet from the floor, activate the doors safety edge, using a crate, skid or alike.Do not introduce any part of your body to the door system during testing. The door should reverse

to the full open position. Remove the obstruction.

10.The door will begin to close within 1 sec., If dip switch #1 is in the "ON" position. If dip switch # 1 is in the "OFF" position, the door will wait 10 sec. Before beginning to close.The door should fully close to the floor. (the door will not motor down, it will gravity descend)

11. Repeat steps #7 and #8.

12.When the door is approximately ½ way to the floor, interrupt the safety photo eye beam, by blocking with a piece of cardboard or alike. Do not introduce any part of your body to the door system during testing. The

door should reverse to the full open position.Remove the obstruction.

13. Step #10 repeats.

14.When the door is approximately ½ way to the floor, depress and hold the "STOP" button on the three button control station.The door should stop.

15. Release the "STOP" button on the control station. Step #10 repeats.

16. Depress the "OPEN" button on the three button control station. The door should open to the full open position. The unit is now ready to be returned to service.

OPERATOR MOUNTING

Before your operator is installed, be sure the door has been properly aligned and is working smoothly. The operator may be wall mounted or mounted on a bracket or shelf. Ref er to the illustr ation and instructions below that suits your application. This motor operator is an integral part of the door system. The motor operator, controls door descent speed under power outage conditions, therefore the motor operator mounting surface is of major importance.The mounting must provide the following:

- All surfaces should be flat, square, and parallel to the door shaft

- The mounting surface must be rigid, and braced off as required

- When wall mounting the motor operator, it should be through bolted to the wall

- All (8) motor operator mounting points MUST be used

- All mounting hardware should be a minimum of grade 5

1a. Bracket or Shelf Mounting

The operator may be mounted either above or below the door shaft. The optimum distance between the door shaft and operator drive shaft is between 12” - 15”. Refer to Figure 1.

NOTE: The door hood, end plates, and mounting bracket must be rigid, and provide adequate structural support.

FIGURE 1

(Right Hand Unit Shown)

1b. Wall Mounting

STICKING OR BINDING DOORS MUST BE REPAIRED. DOORS, DOOR SPRINGS, BRACKETS AND THEIR HARDWARE MAY BE UNDER EXTREME TENSION AND CAN CAUSE SERIOUS PERSONAL INJURY. CALL A PROFESSIONAL DOOR SERVICEMAN TO MOVE OR ADJUST DOOR SPRINGS OR HARDWARE.

ENTRAPMENT PROTECTION ACCESSORIES

SENSING EDGES

All types of sensing edges with an isolated normally open (N.O.) output are compatible with your operator. This includes pneumatic edge. If your door does not have a bottom sensing edge and you wish to purchase one, contact the supplier of your operator.

The operator has been pre-wired to accept connection of a reversing edge device. Connect the normally open contacts to terminals J2-5 and J2-6 on the PCB Board. The auxiliary limit switch will de-activate the safety device during the last few inches of the door's downward travel.

NOTE: F or wiring connections refer to wiring diagram supplied with operator.

Important Notes:

a) Proceed with Limit Switch Adjustments before

making any sensing edge wiring connections to operator as described below.

b) Electrician must hardwire the junction box to the

operator electrical box in accordance with local codes.

TAKE-UP REEL: Take-up reel should be installed 12” above the top of the door.

COIL CORD: Connect operator end of coil cord to junction box (not supplied) fastened to the wall approximately halfway up the door opening.

LIMIT SWITCH ADJUSTMENT

MAKE SURE THE LIMIT NUTS ARE POSITIONED BETWEEN THE LIMIT SWITCH ACTUATORS BEFORE PROCEEDING WITH ADJUSTMENTS. BE CERTAIN THAT DIP SWITCH #2 IS IN THE “OFF”POSITION (CDO MODE) BEFORE MAKING ADJUSTMENTS.

1. To adjust limit nuts depress retaining plate to allow nut to spin freely. After adjustment, release plate and ensure it seats fully in slots of both nuts.

2. To increase door travel, spin nut away from actuator.To decrease door travel, spin limit nut toward actuator.

3. Adjust open limit nut so that door will stop in open position with the bottom of the door even with top of door opening.

4. Repeat Steps 1 and 2 for close cycle. Adjust close limit nut so that actuator is engaged as door fully seats at the floor.
