DIVISION 11190 DETENTION
EQUIPMENT
GENERAL SCOPE:
CELL DOORS
A. GENERAL:
1) Each cell door
will be rack and pinion driven,
and controlled electrically by remote
means through the operation of an
individual motor above the door.
2) System allows for unlocking at
the door from a Release Cabinet in
the event of a power failure.
3) The use of chain
and sprocket, screw type drive or
air system as a means to propel
cell doors will not be acceptable.
4) Devices using
springs to assist operation will
not be allowed. (A spring will be
allowed on the motor hold down and
stops)
5) Cast or Nylon
Parts will not be allowed on Carriage
Unit.
6) While in operation
there shall be no more 1/4" over-travel
movement at the door.
B. ELECTRICAL FUNCTIONS: The control
means will enable the operator to
accomplish the following from the
Control Panel:
1) Unlock, open
and lock open, or unlock, close
and lock closed the selected cell
door.
2) Reverse the
direction of travel of the selected
door without completing a cycle.
3) A door may be
stopped in mid travel by exerting
a force of 40 lbs of pressure. After
the blocking obstruction is removed,
the door will continue to move in
the selected direction and lock
automatically. The blocking of one
or more doors will not affect the
operation of the other doors.
4) Although the
door movement can be stopped by
the application of approximately
40 lbs of pressure, the direction
can not be reversed at the door.
However, the operator can reverse
the direction electrically from
the control panel.
5) The time to
open a 2'-4" door will not exceed
6 seconds.
C. MECHANICAL FUNCTIONS
- The mechanical means will enable
the operator to accomplish the following:
1) With the lever
in the Release Cabinet in the "ELECTRIC"
Position the Officer can electrically
unlock, open and lock open or unlock,

door by use of the switch on the
Control Panel.
2) With the lever
in the Release Cabinet in the "KEY"
Position the Officer can manually
unlock, open and lock open, or unlock,
close and lock close door at the
door by use of a special key.
3) With the Lever
on the Release Cabinet in the "RELEASE"
Position the system will automatically
unlock all cell doors.
4) Mechanically
lock door in the closed or open
position at no less than two points
at the head and at one point at
the bottom of the door. Bottom locking

and operate automatically in a vertical
tamperproof column. Lock bar shall
engage a minimum of 3/4” into the
door guide in the locked open or
locked
closed position.
5) The loss of
electrical power will cause a door
or doors in transit to be held in
that location (devices which allow
"free-wheeling" will not be accepted).
Further movement of a door or doors
during power failure can only be
accomplished by use of the "KEY"
or "RELEASE" mode from the Release
Cabinet.
