Damper actuator on/off & modulating
Damper actuator on/off & modulating
(OP)
Hi , I am looking for an actuator to work in a fire type situation for auto and manual control through a control panel
The actuator is to be both modulating when in auto and on/off(open/closed)when in hand at the panel
The actuator will be spring return and with power on it 24 V it will open fully, remove the 24 V it will close fully
With power on it, and 0-10 V control signal it will modulate it is position
Does anyone know they type I need..model number..??
I can only find on/off or modulating but not both

If I take any mod actuator 0-10v and break the 0-10 v signal will I use the 24 v power supply to operate on/off ??

What kind of application is this for?
You mention a fire situation, do you mean a combination fire/smoke damper? a control damper to work as a smoke damper?
You would be controlling this damper from DDC panel during "normal" operation and then thru FACP during a fire situation? i.e. smoke?
Or is this a fire damper? can't be of course.
I think you may be complicating your controls to save a damper. I'd keep it simple - OPEN/CLOSE; START/STOP is best when it comes to fire situations. Firemen are not savvy to operate complicated dampers with multiple functions, they want simple ON/OFF type activation for ENABLE/DISABLE at the FACP. NO MODULATION FOR FIRE SITUATIONS

Pay attention to HerrKaLeun's and cry22's notes.
