Description______________
Type 2B.3 locking devices are high
security, motorized sliding cell door
operating and locking systems for use
with any doors not exceeding 300
pounds.
Applications_____________
2B.3 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 freewheeling in the electrical 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 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 event of power failure, doors may be
manually opened or closed by sliding
the door.
Locking System__________
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 Series has been in service since
1962, and this system has been tested
at 500,000 cycles.
Standard Features_______

Electrical/mechanical control
cabinet – Electrical switches may be

as required. The following switch
functions are available:
Three-position operating switches –
(OPEN-GROUP-CLOSE).
Group switch – Provides group
control (OPEN-OFF-CLOSE).

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.
G90 galvanized finish available.
