2.01 MANUFACTURER

Revolving door shall be as indicated on plans, and as manufactured by Horton Automatics, a division of the Overhead Door Corporation.

2.02 EQUIPMENT

A. DOOR UNITS:

Shall be a three-wing design Control Flow Series 9100, as supplied by Horton Automatics. Door design shall be (specify) Fixed Wing (or) equipped with Magnetic Breakaway.

B. OPERATOR:

The operating mechanism shall be a fully adjustable power operator. Upon receipt of a signal to operate, the operator shall move the door at the required speed. The operator shall be so designed that someone desiring a faster speed can push the door with no harm to the operator. The operator shall be supplied with 1/4 HP 500 RPM high torque, DC, UL recognized motor, gear box, and control panel. Control panel shall provide adjustable speed control. The double seal, corrosion-proof, cast iron gear case shall contain case hardened (60Rc) helical gears in synthetic, low temp oil bath lubrication. The operator shall allow a single passage in the unauthorized direction or manual operation in either direction upon actuation of a remote keyswitch accessible by only security personnel. A 1 1/2" solid steel shaft shall serve as main linkage to connect the operator to the revolving door.

The door quarterpoint positions shall be adjustable to suit the traffic and desired function. See drawing for setting.

a. Motor drive control shall be enclosed to prevent EMI noise from affecting the microprocessor control.

b. Microprocessor control shall have four modular cards with edge connector for ease of service.

1. Voice annunciator card - must be 100% solid state. Tape recorded message will not be accepted.

2. Output card - controls the motor drive system.

3. Input card - from motion detector, security mat, safety switch, handicap switch, etc.

4. Microprocessor card contains the controlling software on eproms.

An RS-232 part shall be provided for communication with external display (by others) to monitor door status, violations and operation. The logic shall also accept commands from this external terminal overriding normal lock.

Modular control system shall be capable of exchanging the individual control circuits without having to replace the entire system.

2.03 TRAFFIC CONTROL FUNCTION - DAY/NIGHT OPERATION

To provide a barrier free exit to the non-secure area while maintaining a restricted entrance to the secure area.

A. ONE-WAY SECURITY:

Traffic shall be allowed to pass unrestricted from one direction. Traffic shall be controlled from the opposing direction. A keyswitch shall be used to gain authority to enter through the secure areas for security personnel use. Actuation of that switch shall also be capable of providing manual operation in either direction. The keyswitch shall also return the systems to normal operation. The free access side shall be supplied with a motion detector to set the door in motion. The actuation shall cause the door to revolve at the rate of 2 to 6 RPM's (adjustable) for a complete turn, after the actuating signal is removed, slow, then stop at the quarterpoint.

Any attempt of entry from the controlled access side during this operation shall be detected. The only way passage will be allowed from the controlled access side is by authority from the keyswitch.

B. DAY OPERATION/NON-SECURITY MODE:

Upon a signal from others (dry contact) the control shall operate as a two-way free access in both directions. Actuation shall be from microwave motion detectors (optional), activated by logic software. Any mat signal shall cause the door to turn to avoid entrapment. The bi-color LED shall also glow green denoting day operation.

2.04 SECURITY FUNCTION

The door shall be equipped with an electric brake. An area detection mat shall be placed inside the door where traffic passage is to be controlled.

The electric brake shall be a fail-safe design with battery backup (opt.) to maintain fail-secure in the event of power failure. The battery backup system shall also have integral anti-entrapment logic built in to eliminate any possible entrapment.

The brake shall have enclosed construction with sealed ballbearing and zero backlash.

Any attempt of passage by someone into the unauthorized area shall cause the door to ramp to a stop and a solid state voice annunciator will say "SECURITY VIOLATION, DOOR WILL REVERSE." (Repeat tape recorded systems will not be acceptable.) The door will then rotate backward to a position allowing the secure area to be cleared and proceed in slow speed for 1/3 revolution and then resume normal speed.

The door can be used as a fully automatic door by adding another microwave and a switch to control both the mat and detector.

2.05 HANDICAP SPEED

A momentary contact switch with 1" round pushbutton shall be placed at the entrance to the door. The switch mounting plate shall bear the Handicap Logo and reads, "PUSH BUTTON TO SLOW DOOR." Activation of this switch shall place the operator into a reduced speed, 2-3 RPM, for selected (adjustable) seconds.

An optional voice annunciator can be added to say, "DOOR IN SLOW SPEED, DO NOT PUSH" when in the reduced speed mode.

2.06 SAFETY

A. BACK PRESSURE SENSING CIRCUIT:

Should the door wings encounter an obstacle at any point in rotation that creates a back pressure on the door of 5-10 pounds (adjustable), the door shall go into the EMERGENCY STOP MODE for 2-15 seconds where the motor circuit is completely turned off before normal operation is restored.

B. ENTRAPMENT PROTECTION:

The control shall be designed so as to prevent entrapment. Power failure will result in fail-safe operation. Optional fail-secure operation is supplied by a UPS battery backup (min. 1/2 hour) including anti-entrapment logic. This backup system shall continuously monitor motor and brake functions to assure proper operation. Should any periods of power interruptions, or malfunction be detected, the brake shall be engaged and a set of N.O. and N.C. contacts provided for external alarm or lights. (by others)

C. EMERGENCY STOP:

The door shall include a safety stop switch. Should an object be caught between the door and the drum edge, the safety switch in the drum edge shall signal the door to stop; the brake shall then engage. The door shall not be allowed to rotate to a point which would allow security to be violated. After 2-15 seconds (adjustable) the door shall restart in slow speed and accelerate to normal speed. The Emergency Stop shall work in normal rotation and during backup (security violation). To prevent nuisance stopping, the door will have a safety edge delay module installed that ignores safety edge activations of less than 1/4 second (such as briefcases, luggage) but ramp the door to a stop on activations over 1/4 second. After the adjustable delay, the door will start at slow speed for 1/3 revolution and resume normal speed.

D. MAGNETIC BREAKAWAY (Optional): The wings shall be held in their respective positions under normal conditions by electro-magnets capable of holding with 1,000 pounds (min) force to maintain building integrity. Upon a signal from a smoke or fire alarm or remote emergency button (by others), power to the door operator and magnets shall be removed. Wings will maintain their respective position but can be collapsed to the emergency position by exerting a force of 15-25 pounds at the outside stile.

2.07 FINISH

Specify: 204R1 Clear, 313R1 Dark Bronze, Other

2.08 SIGNAGE (Optional)

Backlit fluorescent signage shall be placed on both sides of the canopy reading:

Authorized side: "BAGGAGE CLAIM" or "ENTER" (white letters on a green background)

Restricted side: "DO NOT ENTER" (white letters on a red background)

2.09 ENCLOSURE

The enclosure shall be constructed so that proper clearance shall be maintained and weather seal assured.

2.10 DOOR CONSTRUCTION
