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 the supply voltage is applied.
The lock is mounted on the inner surfaces of the locker transversely to the door and is 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 eliminating 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.

TECHNICAL DATA

OPERATING CONDITIONS
The lock operation environment must be explosion-safe, free of current- conducting dust or gases that cause metal corrosion and destroy 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.

INSTALLATION AND CONNECTION

LOCK AND LATCH MOUNTING

  1. Screw out the screw on the front surface of the lock and remove the cover.

  2. Mount the lock on a wall, at a distance of 15mm from the locker wall edge.
    Promix SM308 Electromechanical Lock with Pusher And Door Position Sensor -
figure 5

  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 the voltage is applied, the lock must push out the 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.

EMERGENCY OPENING OF THE LOCK
For the 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. Promix SM308 Electromechanical Lock with Pusher And Door
Position Sensor - figure 7

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. Lock energizing.
  2. Normally open contact of the sensor.
  3. Common contact of the sensor.
  4. 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.

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).

See operating voltage range in 5.2. Avoid supply of overvoltage.
Example of the lock connection to the remote control system Promix-RDS.

Provide a reliable electric contact. To prevent short-circuiting, insulate places of connection.

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 the impact load on the lock and extends its service life.

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 enter with friction.| Restore the position of the door that changed in the course of operation. If  restoration is impossible, adjust the latch (see 6.1)

MAINTENANCE

Maintenance of the lock is performed at least once every two months and includes:

  • Visual inspection of the lock to check the reliability of fastening. If necessary, tighten the fasteners of the lock and the latch.
  • Checking the proper position of the latch. (see section 8).

The lock does not need lubrication!

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.

SAFETY REQUIREMENTS

The design of the locks ensures the safety of personnel involved in mounting and maintenance.
Due to low DC supply voltage, the products correspond to class III as per GOST 12.2.007.075 and are electrically safe. Fire safety of the locks is ensured by use of non-combustible or hardly combustible materials, and low supply voltage.

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 environmental protection.
