Electromagnetic actuator
Notes
The initial position of the damper flap of the fire damper is "open", of the smoke damper - "closed".
The operating position of the damper flap of the fire damper is "closed", of the smoke damper - "open".
Symbols on the diagrams
EMP - electromagnetic actuator;
EM - electromagnet;
KV, KV1, KV2 - limit switches;
KN - button;
KK - terminal block.
The electromagnetic actuator is installed on the valves:
- fire dampers with normally open flap;
- smoke dampers with normally closed flap.
The method of transfer of the damper from the initial position to the working position:
- automatic from the thermal lock at a temperature inside the valve of 72 ° C (only for fire retardant valve in combination with a thermal lock);
- automatic by fire automation signals;
- remote from the control panel:
- from a toggle switch at the place of valve installation (toggle switch not included in the delivery set).
Method of transferring the damper from the working position to the initial position:
- manually
The principle of operation of the damper.
The valve is actuated when the supply voltage is applied to the solenoid or the thermal lock is broken. The solenoid lever releases the damper and the return spring moves the damper from the initial position to the operating position. In the operating position the damper is locked by the bolt. The butterfly valve is manually moved from the operating position to the home position using a special spanner supplied with the valve. As the actuating mechanism of the actuator an electromagnet with supply voltage 220V or 24V is used, the control signal for the actuation of which is the voltage supply (not more than 15-20 s). The actuators are equipped with microswitches for controlling the flap position, as well as a terminal block (except for actuators installed on KDM valves).
