HVAC systems electric fire damper / air damper

HVAC systems electric fire air damper introduction

1.The smoke senor send a firm alarm signals and controller switch on, valve opened

2. Open the valve by hand.

3. Reset by hand.

4. The valve is opened automatically when temperature reach 280℃.

5. The valve outputs electric signals, interlocked with fire control system.

6. BYK-BSD is remote control (no more than 6 m).

7. This electric fire air damper including fire air damper and aluminum grill air diffuser.

Electric fire air damper main parameter

1. The air leakage volume different pressure300 pa: 700 m3 / m2 .h
2. The control voltage: DC 24 v
3. The current action: 0.3 A
4. The micro switch contacts capacity: AC380V 3 a
5. The drag coefficient when full open: < 0.5 structure
6. The main components: the valve body, valve leaf, shaft and bushing, check the mouth and actuators

Attention:

1. Check air volume damper, fire damper body not deformation before installation, actuator manual action can flexible open and close, equipped with fusible piece to see the fusible piece is complete.

2. The air volume damper body and direction position should be correct when installation, the valve position when installing does not match, please don't use blunt knock each air volume damper, fire damper parts, should repair the installation location.

3.  After installation of air volume damper, clean the check should be made for the body, the body can’t have impurities. 

4. When the valve plug, should check whether the actuator power supply voltage level is reached DC24V. According to the electrical connection that confirms to rear can electricity debugging.
