4. DESIGN AND PRINCIPLE OF OPERATION
The lock Promix-SM308 is produced in a normally closed version, i.e., it is in the closed state
when de-energized and opens as supply voltage is applied.
The lock is mounted on inner surfaces of the locker transversely to the door andis operable in
both vertical and horizontal positions. The mating part (latch) is mounted on the door.
As the door is closed, the latch is inserted in the lock and becomes blocked therein. As supply
voltage is applied, the lock deblocks the latch and pushes it with a built-in pusher, which allows to
eliminate mounting of a handle on the door.
The spring-loaded pusher of the lock is connected to the door position sensor. The operating
principle of the sensor is described in 6.3.
5. TECHNICAL DATA
5.1 OPERATING CONDITIONS
The lock operation environment must be explosion-safe, free of current-conducting dust or
gases that cause metal corrosion and destroying insulation of current conductors and electric
elements, free of current-carrying dust or water vapor, and preventing ingress of water, steam,
fuel and lubricants.
Climatic conditions of operation –У3.1 as per GOST 15150-69 with extended temperature
range:
 ambient temperature: from -30 to +50 °С;
 Relative air humidity: not higher than 98% at 25°С or lower temperatures without moisture
condensation and hoar-frost formation;
 installation indoors or outdoors excluding ingress of moisture, dust, dirt, etc. inside the lock.

6. INSTALLATION AND CONNECTION
6.1 LOCK AND LATCH MOUNTING
1. Screw out the screw on thefront surface of the lock and remove the cover.
2. Mount the lock on a wall, at a distance of 15mm from the locker walledge.
3. Connect the lock to the power supply (see 6.3).
4. Insert the latch into the lock.
5. Test operability of the lock –as voltage is applied, the lock must push outthe latch.
6. Fasten the latch to the door at a distance of 20±3mm from the base edge of the lock (see
Fig. below).
7. Test operability in door closing.

6.2 EMERGENCY OPENING OF THE LOCK
For emergency opening of the lock, insert a wire (e.g., a paper clip) and, having caught the
part “lever” (see the Figure below), move it until the lock operates.
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.
Purpose of terminals:
1-2 Lock energizing.
3 Normally open contact of the sensor.
4 Common contact ofthe sensor.
5 Normally closed contact of the sensor.
Connect the lock power wires adhering to the
following polarity:
Terminal 1 –positive pole of the power supply;
Terminal 2 –negative pole of the power supply;
Application of voltage of reverse polarity does not
provide the lock operability but does cause its failure.
Move the lever until
operation

See operating voltage range in 5.2. Avoid supply of overvoltage.
Provide a reliable electriccontact. To prevent short-circuit, insulate places of
connection.
When the pusher is embedded in the lock (the door is closed), the output contacts 3-4 of the
sensor are closed 3-4 (5-4 are open); when the pusher is shifted out of the lock (the door is
open),the output contacts 3-4 of the sensor are open(5-4 are closed).
Example of the lock connection to the remote control system Promix-RDS.
7. SPECIAL ASPECTS OF INSTALLATION AND
OPERATION
1) The possibility of using the lock and the place of installation (outdoors or indoors) are
determined by the installation organization on the basis of the design features and the lock
operating principle, method of installation, room criticality level, the purpose of 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.
8. TROUBLE-SHOOTING
Troubles and problems
Remedies
The lock does not fix the latch (the door is
not fixed in the closed state).
Check the absence of supply voltage.
Adjust the latch position (see 6.1) so that the
latch, with the door closed, enters the lock slot
until the catch hook operates.
The latch does not enter the lock 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 6.1)

The lock does not need lubrication!
The warranted operation period is 12 months from the date of sale but not
longer than 18 months from the day of acceptance by the manufacturer’s QCD.
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 8).
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 ГОСТ 12.2.007.0-
75 and are electrically safe.
Fire safety of the locks is ensured by use of non-combustible or hardly combustible materials,
and low supply voltage.
