KR SLIDING DOOR LOCKING DEVICE
Type KR Devices are medium security, sliding cell door
locking devices for use with doors not exceeding 300 pounds.
APPLICATIONS
KR Devices are applicable to any multiple cell or inmate room door situation requiring
selective, remote, electrical unlocking and manual movement of the door either
open or closed.

 FUNCTIONS
Unit unlocks selected individual doors from a remote push button. A door starter then opens the door(s)
a few inches.
Doors opened or closed manually automatically snaplock and deadlock.
In event of emergency or power failure, gang unlocking is accomplished in a remote,
mechanical release cabinet. Doors are then opened the remainder of the way by
hand.
LOCKING
SYSTEMS
Upon closure, each door automatically
locks at two concealed points at the rear 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 KR Devices have been thoroughly function tested, and have been in service since 1962. Folger Adam Security Inc. has established test criteria for the system at 500,000 cycles.
STANDARD
FEATURES
- Motor voltage: 120VAC
- Plug-type connectors - Simplify wire harness installation.
- Individual motor unlocking - Each door is unlocked by its
own motor.
- Heavy duty construction - KR Devices are ruggedly built for
a range of detention environments.
- Tamper-resistance - All openings in housings are baffled to
resist inmate tampering.
- Selective unlocking - Each door may be unlocked by an individual
control switch, group-unlocked with an all-door switch, or individually released
through a port. See optional controls.
- Sloped-top housing - Resists hiding of contraband.
- Flat-top housing - Provided where the device must install close
to the ceiling.
- 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, and mid-travel.
- Mechanical release cabinet - A three-position lever handle
or crank handle is provided.
- Lever position controls device operation and allows:
1. Deadlocking - All doors isolated from electric or manual operation.
2. Electric operation - Door controlled from a remote location.
3. Emergency unlock - Gang release of all doors in event of emergency or power
failure.
- Full-length wire tray - Simplifies routing of electrical wire/harnesses.
Runs the full length of the housing.
- Meets NFPA 101 Life Safety Code.
- Locked open feature - Permits doors to be held open and immovable.
OPTIONAL
FEATURES
- Motor voltage: 24DC
- Mechanical release column - A release column containing a #82 Deadlock may
be added to provide local mechanical locking and unlocking by paracentric prison
key.
- Two-position motor (MC) - Unlocks the door by an electric switch. Once unlocked,
the mechanism remains in the unlocked position until electrically selected to
relock. The door may then be deadlocked in either the open or closed position.
- Key switch - An electric key switch may be added to the above column for local
electric control.
- Inmate control feature - Release columns may be equipped with an inmate push
button on the cell side, and a key cylinder on the outside. Inmates may exit by
pressing the push button, and reenter using a key. Feature may be canceled at
a remote console or other control point.
- 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 mechanical release cabinet, or located remotely as needs
dictate.
1. Individual Push Button Unlocking
2. Group Switch - Provides group unlocking.
3. Power Cut-off switch - Cuts electric current to controls.
Indication lamps may be installed in conjunction with switches to show deadlocked
closed or open status of each door. When used, indication is as follows:
RED: - Open of locked open
GREEN: - Deadlocked closed
- Custom graphic consoles - In many cases, it may be desirable to separate electric
controls form the mechanical cabinet located near the cells. For larger installations,
or those with particular needs, custom-built consoles may be easily provided with
floor plan graphics screened on the control panel, and an array of specialized
features. (See Controls Section for further details)
- Wire harness - For applications using a series of locking devices, a wire
harness(es) may be specified to interconnect terminal strips in the mechnical
control/release cabinet to a plug connector at the door operating unit. Simplifies
routing of wire, and saves installation cost and time.
