2B
SLIDING DOOR OPERATING DEVICE
Type 2B Locking Devices are high security, motorized
sliding cell door operating and locking systems for use with any doors not exceeding
300 pounds.
APPLICATIONS
2B 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 and deadlocks open, or closes and deadlocks closed pre-selected individual
doors or door groups, via optional electric controls. Gang release is by mechanical
release cabinet.
Door movement may be stopped in mid-travel. The door is not free-wheeling in the
electric mode. Pressure exerted by a door in travel is factory set at approximately
40 pounds. Force is adjustable between 20 and 50 pounds.
Direction of travel of any individual or selected group of doors may be reversed
without interrupting the operation of other doors.
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 the event of emergency or power failure, any door may be unlocked manually
at the door, and moved by hand without changing the locked status of any other
doors.
In the event of power failure, doors may be manually opened or closed by sliding
the door.
LOCKING
SYSTEMS
Upon closure, each door automatically
deadlocks at two concealed points at the rear edge of the door. Upon opening,
each door automatically deadlocks open at the front 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 2B Device has been thoroughly
function tested, and in service since 1962. Folger Adam Security Inc. has established
test criteria for this system at 500,000 cycles.
STANDARD
FEATURES
- Motor voltage - 120VAC
- Plug-type connectors - Simplify wire harness installation.
- Rugged chain drive - Provides sure action of the door under a variety
of conditions and installation variables.
- Heavy duty construction - 2B 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.
- Adjustable torque limiter - Simple adjustment of force exerted by
the door. May be set between 20 and 50 pounds.
- 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 deadlocking - 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.
