 FUNCTIONS
Unit unlocks, opens and locks
open; or unlocks, closes and deadlocks closed, an individual door.
Door movement may be stopped in mid-travel, leaving the door in a fixed (non-movable)
position. The device must be electrically or mechanically operated or moved to
the open or closed position to lock. Pressure exerted by a door in travel is approximately
40 pounds.
Blockage of a door will not cause motor damage. When obstruction is removed, the
door continues movement to the open or closed position.
Individual doors may be mechanically unlocked at the door.
LOCKING
SYSTEM
The door automatically deadlocks
closed, and locks open at two points on the rear edge of the door. Locking components
are concealed, and not subject to inmate tampering. Components do not project
into the door opening.
TESTING
D3B Operators have been thoroughly
function tested, and have been in service since 1994. Folger Adam Security Inc.
has established test criteria for this system at 500,000 cycles.
STANDARD
FEATURES
- Motor voltage - 120VAC
- Precise, rack and pinion gear drive
- Detention construction - D3B Operators are built for the
detention environment.
- Tamper resistance - All openings are baffled to preclude inmate
tampering.
- Sloped top housing - Eliminates hiding contraband. Flat top
housing is provided where operator must install close to ceiling.
- Automatic deadlocking - When fully closed, top and bottom locking
points on the rear of each door are forced down into deadlock.
- Indication switch - An internal switch monitors the deadlocked
condition of both locking locking points.
- Meets NFPA 101 Life Safety Code®
- Remote electric unlocking - Each door is controlled by a three-position
switch (OPEN-OFF-CLOSE)
- Emergency manual unlocking - In event of power failure, a release
port may be opened by paracentric key. This action allows use of a "T"
handle to disengage motor. The door may then be manually moved to open or closed
position.
- Emergency release column and door receiver - Provides mechanical
release approximately 3'-6" from the floor. A Paracentric Key unlocks the
emergency release handle. Turning the handle releases the motor and unlocks the
door. The door may the be manually moved to the open or closed position, and locked.
OPTIONAL
FEATURES
- Electrical control console - Provides a three position switch for each corridor
door, accompanied by red and green indication lamps. Operation switches are labeled:
OPEN-OFF-CLOSED. Indication lamps are labeled:
Red - OPEN
Green - CLOSED
- A two position power cut-off switch is also installed to cut power to the
controls.
- Interlocking - Wiring and adaptations may be made to permit interlocking
of two or more doors in a sallyport or vestibule application. Prevents electrical
operation of any other interlocked door.
- Custom graphic consoles - In many cases, corridor operators are merely one
part of a complete security system. For these larger installations, or those with
particular needs, custom built consoles may be easily provided with floor plan
graphics screened on the control panel, and an array of specialized features.
- Electrical operation at the door is optional by adding a Prison Key operated
key switch. Turning the key in one direction opens the door, the other direction
closes it. The key is removable in the off position.
