PART ll - PRODUCTS

2.01 MANUFACTURER

Automatic revolving door(s) furnished and installed shall be of type(s) and size(s)
specified and as indicated on plans and door schedule and shall be manufactured by
Horton Automatics, a division of Overhead Door Corporation.

2.02 EQUIPMENT

A. MANUFACTURED DOOR UNITS: Shall be a three-wing design Control Flow Series

9100. Door design shall be Fixed Wing or equipped with Magnetic Breakaway.

B. OPERATOR: The operating mechanism shall be an adjustable power operator. The

operator shall be supplied with 1/4 HP 500 RPM high torque, 90 VDC, 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-safe when
power is removed. Operators that fail-secure shall not be accepted. A 1 1/2" (38 mm)
solid steel shaft shall serve as main linkage to connect the operator to the revolving door.
The quarter points shall be adjustable to suit the traffic and desired function.

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

Microprocessor control to have the following four modular cards with edge connectors:
1. Input card from motion detector, security mat, safety switch, handicap switch, etc.
2. Microprocessor card contains the controlling software permanently stored on eproms.
3. Output card controls the motor drive system.
4. Voice annunciator card, a dual voice, field programmable card shall be provided and
must be 100% solid state. Tape recorded message will not be accepted.

An RS-232 port 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.

C. COLLAPSING MECHANISMS: Door will be fixed wing (check with local officials for
compliance) or optional magnetic breakaway(preferable). The door wings shall be held in
their respective positions under normal conditions by electromagnets capable of holding
with 1000 lbs. (4400N) force to maintain system integrity. The door manufacturer shall
supply a set of contacts which when activated by the building's alarm system, smoke
detector or remote emergency button, shall remove power to the door's electromagnetic
locks. The manufacturer shall supply an emergency switch to be mounted near the door
and shall be labeled "Break Glass to Release Revolving Door". Wings will maintain their
respective positions when power is released, but can be broken away into a book-fold
position with 15-25 lbs. (66-110 N) of force. The door manufacturer shall provide a set of
alarm contacts to activate a remote signal (by others) when the door has a loss of power
or the electromagnetic locks have the power removed from them.

D. 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.

1. One-Way Security: Traffic shall be allowed to pass unrestricted from one direction and
controlled from the opposing direction. A keyswitch shall be used by security personnel
to gain access to secure areas. Actuation of that switch shall also be capable of providing
manual operation in either direction. Another keyswitch activation shall return the
systems to normal operation. The free access side shall be supplied with a motion
detector to set the door in motion. An actuation signal shall cause the door to revolve at
the rate of 2 to 6 RPM's depending on door size (adjustable) for a complete turn after the
actuating signal is removed, the door will slow and 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 the keyswitch.

2. Day Operation/Non-Security Mode: A double pole, double throw switch signal by

others (dry contact) shall cause the control to 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.

E. 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 to provide full operation
for 2 hours in the event of power failure. The control shall have integral anti-entrapment
logic built in to eliminate any possible entrapment. The brake shall have enclosed
construction with sealed ballbearings and no backlash.

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

F. HANDICAP SPEED: A momentary contact switch with 1" (25 mm) round pushbutton
shall be placed at the entrance to the door. The switch mounting plate shall bear the
Handicap Logo and read, "PUSH BUTTON TO SLOW DOOR." Activation of this switch
shall place the operator into a reduced speed, 2-3 RPM, for an adjustable time. A second
voice annunciator will say, "DOOR IN SLOW SPEED, DO NOT PUSH" when in the
reduced speed mode.

G. SAFETY: Revolving door unit shall have the following safety features:

1. Back Pressure Sensing Circuit: Should the door wings encounter an obstacle at any
point in rotation that creates an adjustable back pressure on the door of 15-25 lbs. (66-
110 N), 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.
2. Entrapment Protection: The control shall be designed so as to prevent entrapment.
Power failure will result in normal operation for 2 hours and is supplied by a UPS battery
backup including anti-entrapment logic. This system shall continuously monitor motor
and brake functions to assure proper operation. Should any periods of power
interruptions, or malfunction be detected, a set of N.O. and N.C. contacts will activate an
external alarm or lights. (by others)

3. Emergency Stop: The door shall include a wall safety edge 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 a time-delay of 2-15
seconds (adjustable) the door shall restart in slow speed for 1/3 revolution then
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 in software 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.

4. Magnetic Breakaway (Optional): See paragraph “C. COLLAPSING MECHANISMS”.

H. ENCLOSURE: The enclosure shall be constructed so that proper clearance shall be

maintained and weather seal assured.

1. Canopy: Shall match contour of the enclosureCanopy sides to be furnished in

aluminum panel. Ceiling shall be 3/4” (19 mm) thick and be comprised of decorative resin
material laminated to a medium density fiberboard (MDF) substrate.

Optional: Round canopy on segmented enclosure.

Optional: Exterior roof fabricated from .090" (2 mm) anodized aluminum.
Optional: Two ceiling lights with energy efficient lighting systems with flush lens.
Optional: Backlit fluorescent signage shall be placed on both sides of the canopy stating
"ENTER" and "DO NOT ENTER".

I. PANEL/DOOR WING: Nominal narrow stile panel width shall be 1 3/4" (45 mm) wide.
Horizontal rails on door wings shall have sloped stops. An intermediate muntin bar is to
be furnished on each wing for safety and division of glass.

Optional: Medium stile rails.

J. HARDWARE/WEATHERSTRIPPING: Provide locks with five pin cylinders and

concealed bolts on two door wings. A sweep shall be affixed to each wing to provide
adequate weatherstripping and ensure weatherseal. Lower shaft bearing shall be surface
mounted, not requiring excavation below floor line.

2.04 RELATED WORK REQUIREMENTS

A. ELECTRICAL: 120 VAC, 60 cycle, 1 phase, 15 amp. Non-North American voltages

can be 240 VAC (operator must have 240 volt power supply). Remote switch locations
