PART II - PRODUCT

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 four-wing design Control Flow Series 9200 one or two-way controlled access security, as supplied by Horton Automatics.

B. OPERATOR: The operating mechanism shall be an adjustable slow speed power operator. Upon receipt of a card signal to operate, the operator shall move the door at the low energy and speed mode. 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, 90V, 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 fail secure when power is removed. A 1 1/2" solid steel shaft shall serve as main linkage to connect the operator to the revolving door.

The door quarter points 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.

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

A. TWO-WAY SECURITY: Traffic shall be controlled from both directions. The Access Control System (ACS) shall be placed at the entrance to each side to obtain clearance to allow passage through the door. The Access Control System shall cause the electric brake to unlock and set the operator in motion. The actuation shall cause the door to revolve at the rate of 3 to 5 RPM's (adjustable) for one quarter turn, then stops at the next quarter point and the electric brake shall lock the door.

Any attempt of entry from the unauthorized side during this operation shall be detected. The only way passage will be allowed from either side is by authority from the Access Control System (ACS).

One-way security requires an additional motion detector.

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. The door shall quarter point in the (X) position. Upon release of the dry contact, the door shall automatically convert to security operation and re- quarterpoint in the centerpoint position. (+)

2.04 SECURITY FUNCTION

A. ACCESS CONTROL SYSTEM (ACS): The operator microprocessor shall have the capability to interface with an Access Control System furnished by others. The ACS shall be placed at the door entrance on the side where access is being controlled.

B. SECURITY FUNCTION: The door shall be equipped with an electric brake. An area detection system shall be placed inside the door where traffic passage is to be controlled.

The electric brake shall keep the door in a normal locked position. It shall be a fail-safe design and have enclosed construction with sealed ballbearings and zero backlash.

The operator control shall interface with a visible indicator panel of pending requests. If no requests are present, the red indicator shall be on. When an approved signal is generated from the Access Control System, the visible indicator panel will change from red to green, signaling the user that an authorized entry is possible. If the signal was not approved, the red indicator shall stay on so the person will know to make another request. (In day mode, green signal shall be illuminated).

When the green light appears, the person shall enter the door opening and step on the floor mat or detector system. This unlocks the electric brake and turns on the operator. The door will slowly accelerate and rotate at the rate of 3-5 RPM. Both the acceleration rate and speed are adjustable. The door indexes one quarter turn, allowing entry and then relocks. The operator shall always be adjusted with sufficient power to drive the door to the locked quarter point position.

A valid signal from the ACS will not be accepted if a signal from the mat is lso detected. The floor mat and the door position indicators shall be monitored to assure that a person passes through the door. If the operator does not register a passage, an additional opportunity shall be granted. The door control system shall communicate with an anti-passback system (by others) to verify passage. Three opportunities for passage are allowed before the request will be canceled.

The microprocessor control must be capable of storing multiple entries from the Access Control System in order to move maximum traffic flow through the door.

An authorized signal shall be held for 10 seconds when the door is not in motion. If no attempt for passage has been made, the signal shall be canceled.

Any attempt of unauthorized passage by someone from the opposite side, at the same time as an authorized entry, shall result in the door being locked by the electric brake. A solid state voice annunciator will state "SECURITY VIOLATION DOOR WILL REVERSE" to inform the person that they have entered a no-entry zone. The operator will then rotate the door backward to a position allowing the secure area to be cleared. When the secure area is clear, the door will resume to normal rotation,

allowing any authorized entry to be completed.

2.05 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 (adjustable) before normal operation is restored.

B. ENTRAPMENT PROTECTION: In DAY operation, an active mat signal shall cause door to continue rotating to prevent entrapment. Plus (+) position prevents entrapment while in the security mode.

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 5-25 seconds (adjustable) the door shall restart and accelerate to normal speed. The Emergency Stop shall work in normal rotation and during backup (security violation).

D. BREAKAWAY SYSTEM (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.
