FIRE DOOR MODE TYPE I FUNCTIONAL OPERATION

1. UNIT HAS AC POWER AND NO ALARM CONDITION:

• The 3-Button 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.

2. UNIT HAS AC POWER AND ACTIVE ALARM CONDITION (ALARM INPUT #1 - Smoke Detector, 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 via controlled descent. If after the door has finished the cycling mode and obstruction has been removed, the door will proceed to the floor.

• In the event of a failure in motor operation, the operator will close via controlled descent.

GENERAL DESCRIPTION

The Fire Door Controller, FDC, is configurable as a standard CDO or a Fire Door Controller (selectable via DIP Switch 2). The Fire Door Mode Type I functions as an integrated fire door control system. It is designed to interface with a normally close (NC) or normally open (NO) dry contact alarm 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.

NOTE: This operator is not a fire alarm system. It can not detect a fire condition.

BATTERY TEST DESCRIPTION

The FDC provides internal battery testing to ensure the battery has not been disconnected and the system can perform it’s intended functionality in the event of a loss of AC power. The battery is checked for presence once an hour for 10 seconds. If this test fails, the battery has failed or is significantly depleted. A major fault (see below) is declared and must be immediately rectified. The battery is also load tested for five minutes. The five minute load test is performed once per week to ensure that the power remaining in the batteries is sufficient to handle an emergency condition. The test will not occur within 12 hours of a power outage or an aborted test due to user input.

The severity of the battery test failure are defined as a minor fault and a major fault are described as follows:

a. Minor Fault. This fault mode occurs when the system

determines that the batteries fail to maintain the minimum voltage between 10 seconds and 5 minutes of load testing. The alarm within operator will begin notification immediately at 3 seconds of every minute. The batteries will be retested every week. The controller will attempt to close the door after 45 days of notification and test failures.

b. Major Fault. This fault mode occurs when the system

determines that the batteries fail to maintain the minimum voltage for 10 seconds of load testing. The batteries are either not connected or are significantly depleted. The system will attempt to close the door after the DIP switch selected alarm delay (see DIP Switch section of this manual). Notification will occur as a 1 second on 1 second off pulse train until Battery Test passes.

Whenever a battery failure occurs, the batteries must be connected or replaced immediately in order to ensure normal system operation. If for any reason the battery voltage drops below the minimum voltage the unit will activate the optional warning system and automatically close the door via a controlled descent.

If the system passes the Battery Test, then all alarms are cleared.

THEORY OF OPERATION

FIRE DOOR MODE TYPE I FUNCTIONAL OPERATION

3. UNIT HAS AC POWER AND ACTIVE ALARM CONDITION (ALARM INPUT #2 - Thermal Sensor, Fuse Link):

• The unit will activate the OPTIONAL warning signal

(horn/strobe), the door will automatically power down 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 seconds, then release the door via 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 close via controlled descent.

• All control station functions will be rendered inactive in this condition.

• The safety edge will remain active.

4. UNIT HAS NO AC POWER AND NO ACTIVE ALARM CONDITION:

• The Close and Stop buttons of the 3-Button 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.

5. UNIT HAS NO AC POWER AND ACTIVE ALARM CONDITION (Alarm #1 or Alarm #2):

• The unit will activate the OPTIONAL warning signal

(horn/strobe), 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 descent of the door (not powered down by the motor).

6. ACTIVATION OF THE INTERNAL THERMAL SENSOR:

• Will activate an alarm #2 switch.

• With AC power present the unit will react as stated in #4.

• With No AC power present the unit will react as stated in #6.

7. ACTIVATION OF THE KEY TEST STATION:

• Key must be activated for 6 seconds.

• The unit will activate the OPTIONAL warning signal (horn/strobe), 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 via controlled descent in order to test the door balance, descent speed, and the movement of the door.

• All sensing devices and control devices will be active. In order to test these devices, see page 6 for procedures.

THEORY OF OPERATION

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 lit on the operator’s control board) and that the batteries are connected.

NOTE: The red “DC” led will NOT be lit on the operator’s control board when AC power is present.

1. Begin the test with the door at the full “OPEN” position.

2. Make certain dip switch #2 is in the “ON” position “FIREDOOR TYPE I” mode.

3. If the 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 #11 and 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 10' 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 3-Button Control Station.

8. Repeat step #4.

9. When the door is approximately 3 to 4 feet from the floor, activate the doors safety edge, (if so equipped) 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 second, if dip switch #1 is in the “ON” position. If dip switch # 1 is in the “OFF” position, the door will wait 10 seconds 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 #6 and #7.

12. When the door is approximately halfway to the floor, interrupt the safety photo eye beam, (if so equipped) 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 half way to the floor, depress and hold the “STOP” button on the 3-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 3-Button Control Station. The door should open to the full open position. The unit is now ready to be returned to service.

THEORY OF OPERATION

To avoid SERIOUS PERSONAL INJURY or DEATH, do NOT introduce ANY part of your body to the door system during testing.

WARNING

INSTALLATION

PREPARATION

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. Refer to the illustration and instructions on the following page 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 (4) motor operator mounting points MUST be used.

• All mounting hardware should be a minimum of grade 5.

ENTRAPMENT PROTECTION ACCESSORIES

PHOTO EYES
