Lf these systems are only tested on an annual basis provisions must also be made to cycle test all associated motorized fire smoke dampers on a six month or semi annual basis.
Motorized fire damper control.
We are involved in manufacturing and supplying high quality motorized fire dampers.
Smoke must be sensed using electrical sensing smoke detectors.
They feature mill finish extruded aluminum frames and louvers.
These power open spring return single panel motorized channel style dampers can regulate exhaust or supply airflow in medium and low pressure commercial applications.
Dayton square motorized smoke dampers are designed for use in hvac system applications where emergency smoke control is required.
Combination fire and smoke dampers are actuated due to the smoke function.
Dayton motorized volume control dampers.
Motorized fire and smoke dampers that are part of any non dedicated smoke control system must be cycle tested every six months.
Upon power interruption the dampers close automatically to prevent the spread of smoke through ducts or ventilation openings in smoke barriers.
These dampers are provided with power motor that are manufactured using finest quality mild steel.
Many smoke control applications require modulating control of dampers.
Spring return actuators are used to close the dampers and then the actuator motor used to open the damper.
