1. PURPOSE
Promix-SM420 series electromechanical rim locks with a pin locking mechanism (hereinafter
referred to as locks) are intended for locking retail space and office furniture which can be
opened remotely by supplying DC power voltage by means of switches (buttons) or controllers of
access monitoring and control systems, audio and video intercoms, code panels or other
devices.
2. LABELING

following information:
1. Lock model
2. Nominal supply voltage
3. Nominal consumed current
4. Date of manufacture and QCD mark
5. Identification number

4. DESIGN AND PRINCIPLE OF OPERATION
Locks are manufactured with a normally-closed design (hereinafter referred to as NC). NC
lock is in the closed state when no voltage is supplied, and in the open state when power is
supplied to the lock.
When closing the door, the latch enters the lock groove and is fixed once it has overcome the
pin force. When voltage is supplied, the pin will be drawn into the lock housing and the latch will
be unblocked.
The possibility of emergency opening of the lock is provided with the help of the unlocking lever
(see cl. 7.1).

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 operating conditions: У3.1 as per GOST 15150-69 with extended temperature range:
 ambient temperature: -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. Install the latch in the area designedfor installation.
2. Insert the latch into the lock and fix the lock so that the latch entersit until click.
3. Connect the lock (see cl. 6.2) and function test by applying supply voltage. The lock must
unlock the latch. Open the door so that the latch disengages with the lock.
4. If the latch is not unlocked when power is supplied, push the door in the area of lock fixation
and apply voltage. Then adjust the latch length providing for the necessary free play and
alignment.
6.2 CONNECTING PROCEDURE
The lock operation is controlled by supplying and blocking power. 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:

See operating voltage range in cl. 5.2. Avoid supply of increased voltage.
Ensure a reliable electric contact. To prevent short-circuit, insulate places of
connection.
White –positive pole of the power supply;
Black –negative pole of the power supply;
Reverse voltage supply does not ensure lock operability, but it does not cause its failure.
Example of the lock connection to the remote control system Promix-RDS.
7. FEATURES OF INSTALLATION AND
OPERATION
1) The possibility of using the locks for access restriction to retail and office furniture and the
place of installation are determined by the installation organization on the basis of the
design features and the mounting method, furniture criticality level, the purpose of the access
restriction regime and other factors (the presence of security providers, video surveillance,
etc.).
2) To prevent door deformation, it isrecommended to install the lockin the area of the handle.
3) When mounting the lock and the latch, it is necessary to ensure their coaxial alignment within
the latch free movement allowance.
4) When the door is closed, the latch must be inserted all the way into the lock. The lock may fail
to open when the door is in “tension” condition, i.e., an external force for opening is applied.
7.1 EMERGENCY OPENING
There is an emergency opening lever
next to the power supply wire output. For
mechanical unlocking of the lock, pull the
lever and then open the door.

8. POTENTIAL MALFUNCTIONS
Malfunctions and problems
Remedies
The lock does not open when supply
voltage is applied.
Check polarity and conformity of the lock supply voltage
to the required value.
Close the door tightly and press on it at the latch
fastening place, and apply voltage to the lock.
After opening of the lock, adjust the latch length.
The lock does not block the latch.
Check the distance between the latch and the lock; if
necessary, increase the latch length.
9. MAINTENANCE
Maintenance of the lock is performed at least once every two monthsand includes:
 Visual inspection of the lock to check the reliability of the fastening. If necessary, tighten
the fasteners of the lock and the latch.
 Check the latch length. If the latch bar abuts against the lock and this leads to non-tight
door closing, or if the latch is not fixed by the lock when the door is closed, adjust the latch
length.
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 25 ºС 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.
Fire safety of the locks is ensured by use of non-combustible or hardly combustible materials,
and low supply voltage.
12. DISPOSAL
The product is not hazardous for human life and health or for the environment; disposal after
its service life is performed without taking any special measures for environment protection.
13. WARRANTY LIABILITIES
