PART II - PRODUCTS

2.01 MANUFACTURER

Furnish and install Series 4900 automatic swing door operator package and related equipment as specified herein. The equipment shall be manufactured by Horton Automatics, a division of Overhead Door Corporation. It shall consist of Series 4000 Electromechanical operator, latch actuating solenoid and actuating device (Optional: See other items required for package. They could be specified in this section). All equipment shall be listed by Underwriters Laboratories, Inc. and meet the provision of the National Fire Protection Association standard 80 and 101.

2.02 EQUIPMENT

A. OPERATOR Series 4900

The Series 4900 fire door operator package consists of the following items per door leaf:

1 -Series 4000 electric swing door operator 1 -Horton Automatics fire exit latch actuator

Note: If a central alarm system is being used delete the heat and smoke detector from this section (Only two are required on single, pairs, or double egress).

Other items required to form a fire door package (because of installation trade problems it is recommended these items be specified in their respective sections).

2 -Heat/smoke detection device, one on each side of the opening

Labeled door and frame

Labeled hinges

Fire exit hardware

Fire detection equipment

The Electric Operating Mechanism shall be Series 4900. It shall be a self- contained electromechanical construction utilizing dripless lubrication for its mechanical parts. The operator shall be shock mounted and concealed in an extruded aluminum case with access for service from the underside. The operator shall not have a sound level in excess of 74dB measured five feet from center line of header housing. The operator shall be readily convertible to any hand required. Opening force shall be accomplished by 1/8 Hp D.C. permanent magnet motor working through eight reduction helical gears to the output shaft. Gear train bearings shall be sealed ball-bearing types. Closing force shall be supplied by a field replaceable Quadra-coil spring (four independent coil springs separated by fiber discs and enclosed in a spring box). The closing spring shall be replaceable without dismantling the gear train. Close speed control shall be accomplished by dynamic braking of the motor and shall be fully adjustable. Operator is to act as a manual closer when power is off or when the master control unit is removed. An On/Off reset switch shall be supplied. The control circuit to the actuating switches shall be 24 VAC Class II Circuit. The master control unit shall incorporate an adjustable time delay of 1 to 30 seconds. It shall provide infinite adjustment to opening and back-check speeds. A locked door motor protection circuit will be supplied that will shut off current to the motor if it is applied when the door is inadvertently locked or otherwise prevented from opening. Power to the motor is restored when the On/Off reset switch is turned back on. The master control unit shall provide for immediate reversal of door motion without undue strain on the drive train by supplying stepped voltage to the motor. Circuitry shall be provided to connect a heat or smoke detector sensing device which shall cut power to the operator causing it to close and position the latching device to receive the fire exit hardware latch.

OPERATING SEQUENCE - (in order of normal use)

1. Automatic opening and closing of a door to allow persons or objects to pass through with no hand operation. The actuating switch signals the operator when to open. When the adjustable time delay expires, the door will mechanically close by spring force.

The Horton Automatics latch actuator replaces the top latch bolt actuator, that is normally mounted to the frame supplied with the fire exit hardware. A solenoid holds the latch actuator arm back when energized, preventing the fire exit hardware latch bolt release button from being tripped by the actuator arm during normal automatic operation.

2. When a fire is detected by the fire detection device, the automatic operation stops and the door operation is converted to the "self-closing mode".

The power to the door operator and latch actuator is fed through the contacts of a relay located in the latch actuator. This relay is being held in the energized position by the normally closed auxiliary contacts of the automatic fire detection device. The detection of a fire trips the fire detection device, thus de-energizing the control relay. The relay contacts then breaks power to the door operator and the latch actuator solenoid. Electricity from the operator is removed, thus eliminating any chance of automatic opening.

The latch actuator is a fail safe design. When power is removed from the solenoid, a spring pulls the latch actuator arm into position to trip the latch release button on the fire exit hardware causing the latch bolts to engage when the door is in the closed position.

The fire exit hardware latches the door closed to contain the fire or smoke and prevent it from spreading to other areas of the building.

3. The fire exit hardware provides a safe, dependable exit at all times. Should an individual need to exit through the door, he can do so by depressing the panic bar which releases the latch bolts. The springs on the door operator will reclose the door as soon as the door is released. The door will close and relatch when the release button on the top latch is depressed by the Horton Automatics Latch Actuator.

4. Resetting to automatic mode: Temporarily break the electrical power to the fire detection equipment and depress the fire exit hardware panic bar on each door. The doors are now in the automatic mode.

2.03 CONTROL SWITCHES

Note to Spec writer: Horton Automatics offers several options to activate the door and provide safety protection on the swing side.

A safety zone of a length 5" more than the door width in the open position shall be provided on the swing side of the door to either prevent the door from opening or hold the door in the open position when the area of the swing of the door is occupied.

Provide a complete activating/safety system of the type specified herein as shown on the drawings. (Specify appropriate selection.)

(2) Series 1700 RailScan safety system shall be mounted in the horizontal rail of the guide rail or be wall mounted. To provide complete safety zone coverage, photobeams shall be housed in an aluminum extrusion and shall be located every five inches in the safety zone.

Note to spec writer: This system only works with clear glass doors or single solid doors.

Activating Device Item (1) and (2) system shall be activated by a:

(3) Motion detector of pattern suitable for door opening size.

(4) C1260 Push Plate Switch to activate door. Switch placement is shown on drawing. A safety system shall be placed on the swing side of the door as described in item (1), (2), or (5) (specify appropriate selection). Safety and Activation System

(5) Electric floor mat switch complete with (a) surface (b) recess trim mounted on each side of the door (activating and safety area) or mounted in the safety area.
