Description______________
Type 3B.2 locking devices are high
security, motorized cell door operating
and locking systems for use with doors
not exceeding 300 pounds.
Applications_____________
3B.2 devices are applicable to multiple
cell or inmate room 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
any other door in the group.
When a single door is blocked, there is
no interruption in operation of any
other door in the group. On removal of
the blockage, the door will automatically
continue 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 relocked
using a special tool.
In event of power failure, all doors
remain in a fixed position, and must be
operated mechanically. Doors are freewheeling when released.
Locking System__________
Upon closure, each door automatically
locks at two concealed points at the rear
edge of the door. No locking
components are exposed at the front
edge of the door where they might be
subject to tampering. Components do
not project into the door opening.
Testing__________________
Type 3B Series have been in service
since 1972 and has been tested to
500,000 cycles.

Electrical/mechanical controls –
Electrical switches may be specified to
provide control of each door in
addition to mechanical function.

as needs dictate. The following switch
functions are available:
Three-position operating switches –

consoles may be easily provided with
floor plan graphics screened on the
control panel, and an array of
specialized features.

using a series of locking devices, a
cell line cable may be specified to
