2B 
SLIDING DOOR OPERATING DEVICEType 2B Locking Devices are high security, motorized 
sliding cell door operating and locking systems for use with any doors not exceeding 
300 pounds.
 APPLICATIONS2B devices are applicable to any multiple cell or inmate room door situation. 
Optional controls provide selective operation of single or groups of doors simultaneously.

Quote Request Please Click on Captions below to display / hide information:  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.
