3. SET OF DELIVERY
4. DESIGN AND PRINCIPLE OF OPERATION
The locks are produced in two versions: normally opened (NO), and normally closed (NC).
NO lock is in the open state when de-energized and in the closed state when voltage is supplied.
NC lock is in the closed state when no voltage is supplied, and in the open state when the lock is
energized. For opening the lock, it is necessary to de-energize a normally open lock or to supply
voltage to a normallyclosed lock.
The external body of the lock and the matching latch plate have a special standard shape and
a suitable for the majority of plastic shapes. Examples of the lock mounting on plastic shapes of
various configurations see at the website www.promix-center.com
As the door is closed, the latch enters the slot in the lock and, overcoming the catch hook
force, is fixed transferring the catch hook from “open” position to “closed” position. As supply
voltage is applied (or, for a normally closed version, as the lock is de-energized), the catch hook
is blocked in the "closed"position and locks the latch.
There is a possibility of emergency opening of the lock
by means of the release lever (see 7.1).
There are adjustments to the position ofthe bolt in the
horizontal and vertical planes. To correct the position
of the roller depending on the gap between the door
frame and the door, adjusting gaskets 3 are used (see
6.2, Fig.6).
The design allows the ignition of the normally open-
type to normally closed and Vice versa (see 7.2).

NC locks are not intended for outdoor installation. NO lock can be mounted
outdoors on condition that it is energized for most time.
5. TECHNICAL DATA
5.1 OPERATING CONDITIONS

6. INSTALLATION AND CONNECTION
6.1 LOCK AND LATCH MOUNTING
1. Drill a hole for lead-out of the power wire at the place of the lock installation.
2. Laythe power wire through the hole produced inside the shape slot and lead it to outside by
drilling the shape.
3. Apply the catch to the fittings slot of the door frame and fix it with self-tapping screws 4 .
4. Using a knife or a chisel, remove two projections 12-14 mm long in the door frame shape
(see Fig.5).
5. Insert the plate with the latch 2 in the slot of the door section so that the roller is at the center
of the lock slot (if the door shape slot is occupied with fittings, then the latch is mounted
without the base(see Fig.6).

See operating voltage range in 5.2. Avoid supply of overvoltage.
Provide a reliable electriccontact. To prevent short-circuit, insulate places of
connection.
6. Mark the edges of the latch plate.
7. Take off the latch and, using a knife or a chisel, remove aflush the projection in the shape to
a width of 60-70 mm (see Fig.7).
8. Mount the latch in the door shape slot and fix with self-tapping screws 5 .
6.2 LATCH ADJUSTMENT
It is necessary to adjust the latch position so that the latch, with the door closed, enters the
lock slot to complete operation of the catch hook. For adjustment in the vertical plane, loosen the
self-tapping screws 5 and shift the latch. For adjustment in the horizontal plane: screw out the
latch screws from the base, drill the necessary holes in the latch
plate, shift the latch, screw the screws into the new holes.
` In case the clearance between the door and the door frame
is greater than the rated 12 mm (the latch does not reach the
lock slot), one or more adjustment shims 3 must be placed
between the plate and the latch plate (see Fig.6).
6.3 CONNECTING PROCEDURE
The lock operation is controlled by means of energizing and de-energizing. For this purpose, a
controller (control board) or a switch (button) is generally used. The controller is mounted in
accordance with its certificate.
Connect the lock power wires adhering to the following polarity:
Red (black with a red stripe) –positive pole of the power supply;
Black –negative pole of the power supply;
Application of voltage of reverse polarity does not provide the lock operability but does cause
its failure.
Example of the lock connection to the remote control system Promix-RDS.
7. SPECIAL ASPECTS OF INSTALLATION AND
OPERATION
1) The possibility of using of the locks for restriction of access to the premises and the place of
installation (outdoors or indoors) are determined by the installation organization on the
basis of the design features and the mounting method, room criticality level, the purpose of
Allowable clearance between the door frame and the door.

the access restriction regime and other factors (the presence of security providers, video
surveillance, etc.).
2) To prevent deformations of the door due to attempts to open the door with the lock closed, it is
recommended to mount the lock in the area of the door handle.
3) It is recommended to install the lock together with a door closer –this reduces impact load on
the lockand extends its service life.
4) Operation of an installed NC lock should be tested only if the supply voltage can be applied
thereto.
7.1 EMERGENCY OPENING
There is an emergency exit rod in the lock case. To mechanically open the lock, pull the
rod, moving it to the "open" position (see Fig.10) and then open the door.
7.2 LOCK TRANSFER FROM ONE VERSION TO
ANOTHER
The lock transfer from the normally open to normally closed version:
1. Unscrew three fastening screws 1 and take off the base.
2. Take off the thrust 2 from the base.
3. Unscrew the fastening screw 3 and remove the bracket of the solenoid.
4. Unscrew the fastening screw 4 and remove the coil and the angle.
5. Withdraw the fastening screw 4 from the coil and insert it in the reverse side of the coil.
6. Fix the coil with the turned angle 5 on the bracket with the screw in the adjacent threaded hole.
7. Mountthe bracket on the body and fix with the screw 3 .
8. Mount the rest on the axle 2 .

The lock does not need lubrication!
The lock transfer from the normally closed to normally open version is
performed in a similar way.
9. Make sure of the lock operability, then mount the base passing the power wire through the slot,
and fix the base with screws 1 .
8. TROUBLE-SHOOTING
Troubles and problems
Remedies
The lock does not fix the latch roller (the
door is not fixed in the closed state).
Check polarity and conformity of the lock supply
voltage to the required value.
Adjust the latch (see 6.2) so that, with the door
closed, the roller enters the snap slot before
operation of the catch hook.
The door is not closed completely since the
latch does not enter the snap.
Perhaps the catch hook was manually transferred
to the “closed” position (see Fig 2).
Deblock the catch hook and transfer it to the
“open” position manually.
The latch roller does not enter the snap
slot, or enters with friction.
Restore position of the door that changed in the
course of operation. If restoration is impossible,
adjust the latch (see 6.2)
The door is not opened when transferred to
the “open” state. To open the door, one has
to press it more snugly to the door frame.
Remove the causes of the non-tight door bearing
against the door frame.
Adjust the latch in the horizontal plane.
9. MAINTENANCE
Maintenance of the lock is performed at least once every two monthsand includes:
 Visual inspection of the lock to check reliability of fastening. If necessary, tighten fasteners
of the lock and the latch.
 Checking the proper position of the latch (see section 6.2).
10. STORAGE AND TRANSPORTATION
Prior to putting into operation, the locks must be stored in the manufacturer’s packing, in
rooms with an ambient temperature of -30 to +50 °С and a relative humidity not higher than 98%
at 25º С in compliance with storage conditions as per GOST 15150-69.
Locks transportation conditions must comply with group C as per GOST 23216-78 in terms of
exposure to mechanical factors, and Ж2 as per GOST 15150-69 in terms of exposure to climatic
factors.
11. SAFETY REQUIREMENTS
The design of the locksensures safety of personnel involved in mounting and maintenance.
Due to low DC supply voltage, the products correspond to class III as per GOST 12.2.007.0-
75 and are electrically safe.

obligatory condition that factory labels are retained on the product body.
To improve product quality the manufacturing plant reserves the right to make
modifications to the product design without prior notice.
Fire safety of the locks is ensured by use of non-combustible or hardly combustible materials,
and low supply voltage.
