 FUNCTIONS
Unit unlocks, opens and locks
open; or unlocks, closes and deadlocks closed, an individual door.
Movement of a door may be stopped in mid-travel to reverse its direction. When
interrupted, the door is not free-wheeling.
Interlocking: Any door not closed and deadlocked will also prevent electric operation
of all other doors.
Manual emergency locking, unlocking and operation is accomplished by a clutch
release and crank located in the locking column.
LOCKING
SYSTEM
The door automatically deadlocks closed at two concealed points at the rear edge of the door. Locking components are not exposed at the front edge of the door and, therefore, not subject to tampering. No components project into the door opening.
TESTING
Type D Operators have been thoroughly function tested, and have been in service since 1949. Folger Adam Security Inc. has established test criteria for this system at 500,000 cycles.
STANDARD
FEATURES
- Motor voltage - 208VAC
- Rugged chain drive - Provides sure action of the door under
a variety of conditions and installation variables.
- Heavy-duty construction - Type D Operators are ruggedly built
for a range of detention environments.
- Tamper-resistance - All openings in housings are baffled to
preclude inmate tampering.
- Sloped-top housing - Eliminates hiding of contraband.
- Flat-top housing - Provided where operator is installed close
to the ceiling.
- Automatic deadlocking - Doors automatically deadlock at two
concealed points at the rear of the door on closure.
- Indication switch - An internal switch monitors deadlocked
condition of both locking points.
- Terminal strip - All internal components are pre-wired to
a terminal strip. The strip is also used for ease of field wiring.
- Meets NFPA 101 Life Safety Code.
- Adjustable friction clutch - In case of door blockage, clutch
slips until obstruction is removed. If not removed, power to the motor is cut
to avoid damage. Adjustment is provided to compensate for various sizes and weights
of doors.
- Emergency manual unlocking and operation - In event of power
failure, unlocking the column provides access to the release mechanism. The door
may then be operated by hand crank.
OPTIONAL
FEATURES
- Electric control cabinet - Control cabinets may be furnished to house all
wiring and switches for each door controlled. Three push buttons are provided
for each door, labeled: OPEN-CLOSED-STOP. Two indicator lamps above the push buttons
indicate door position: Red-OPEN, Green-CLOSED and deadlocked.
- Electrical interlocking - Wiring and adaptations may be made to permit interlocking
of two or more doors in a sallyport or vestibule application. Prevents electric
operation of any other interlocked door.
- Custom graphic consoles - In many cases, corridor operators are merely one
part of a complete security system. For larger installations, or those with particular
needs, custom-built control consoles may be easily provided with floor plan graphics
screened on the control panel, and an array of specialized features. (See controls
section for further details)
