Are MA-223 Fire and Smoke Damper Actuators still available?


Do we have a replacement for the Fire Rated Damper Actuator:

Fire Rated Smoke actuators



Siebe Fire/ Smoke rated damper actuators are all obsolete.


Schneider Electric no longer manufacture any fire and smoke actuators so the MA-223 range are obsolete with no replacement.

The only suggestion we can offer is for the customer to contact the damper manufacturer that this actuator is mounted on and see what they would use to replace the actuator.

We only sold these fire/smoke rated actuators directly to the damper manufacturers.
