3B
SLIDING DOOR LOCKING DEVICE
Type 3B Locking Devices are high security, motorized
sliding cell door operating and locking systems for use with doors not exceeding
300 pounds.
APPLICATIONS
3B devices are applicable to any multiple cell or inmate room door situation.
Optional controls provide selective operation of single or groups of doors simultaneously.

 FUNCTIONS
- Unit unlocks, opens or
closes and locks closed pre-selected individual doors or door groups, via optional
electric controls. Gang release is via mechanical release cabinet.
- Door movement may be stopped
in mid-travel leaving the door in a fixed (non-movable) position. The door must
be moved (restarted) electrically or mechanically to the open or closed position
to lock.
- Direction of movement
of any individual door may be reversed without interrupting the movement of other
door in the group.
- When a single door is
blocked, there is no interruption in the operation of any other door in the group.
On removal of the blockage, the door will automatically continue movement to the
open or closed position.
- In event of emergency,
all doors may be unlocked from the mechanical release cabinet. In mechanical mode,
the motor is disengaged from the rack, and doors may be unlocked or re-locked
using a special tool.
- In the event of power failure,
all doors remain in a fixed position, and must be operated mechanically. Doors
are free-wheeling when released.
LOCKING
SYSTEMS
Upon closure, each door automatically locks 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. Components do not project into the door opening.
TESTING
Type 3B Device has been thoroughly function tested, and have been in service since 1994. Folger Adam Security Inc. has established test criteria for this system at 200,000 cycles.
STANDARD
FEATURES
- Motor voltage- 120VAC
- Plug-type connectors - Simplify wire harness installation.
- Rack and pinion gear drive.
- Heavy duty construction - 3B devices are built for the rigors
of maximum security applications.
- Tamper-resistance - Openings in housings are baffled to resist
inmate tampering.
- Selective operation - Single or groups of doors may be simultaneously
opened or closed and deadlocked.
- Sloped-top housing - Resists hiding of contraband.
- Flat-top housing - Provided where device must install close
to ceiling.
- Cover lock - Device mechanisms are concealed by an outer cover
and unlocked from the release cabinet.
- Automatic locking - When fully closed or open, top and bottom
locking points on the rear of each door automatically deadlock.
- Indication switch - Monitors the deadlocked condition of both
locking points.
- Gang release - From mechanical release cabinet.
- Self-contained - A continuous, surface-mounted housing contains
the drive and mechanical release mechanisms and wiring.
- Full length wire tray - Simplifies routing of electrical wire
harnesses. Runs the full length of the housing.
- Meets NFPA 101 Life Safety Code.
OPTIONAL
FEATURES
- Key Switches - May be added in columns or nearby for local electric control.
- Mechanical release cabinet - A two-position lever handle or crank handle
is provided:Lever provides:
1. Electric operation - Door control from a remote location.
2. Emergency unlock - Gang release of all doors in event of emergency or power
failure.
- Electrical/Mechanical control cabinet - Electrical switches may be ordered
to provide control of each door in addition to mechanical function. These
switches may be built into the same cabinet as the mechanical levers, or located
remotely as needs dictate. The following switch functions are available:
Three position operating switches (Open-Group-Close)
Group Switch - Provides group control (Open-Off-Close)
Power Cut-Off Switch - Cuts off electrical current to controls.
Indication Lamps - Red and green indicator lamps may be installed with switches
to show deadlocked, closed or open status of each door. Special Indication lamps
- An additional (amber) lamp is available. When used, indication is as follows:
RED - Locked open.
GREEN - Deadlocked closed.
AMBER - Moving, or stopped in mid-travel.
- Custom graphic controls - In many cases, it may be desirable to separate
electric controls from the mechanical release cabinet located near the cells.
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.
- Wire harness - For applications using a series of locking devices, a wire
harness(es) may be specified to interconnect terminal strips in the mechanical
control/release cabinet to a plug connector at the door operating unit. Simplifies
routing of wire, and saves installation cost and time.
