Description

Siemens GNA326.1E – Spring Return Electric Actuator for Fire & Smoke Dampers

Fire and smoke damper actuator Siemens GNA326.1E is robust, high performance spring return or fail-safe electric actuator for motorised operation of safety dampers, like fire dampers, fire smoke damper, smoke dampers.

When control signal is applied, actuator drives the damper to operational position, while evenly tensioning the integrated spring. Therefore, in case of power failure, like smoke or fire incidence, the store energy in the spring immediately bring the damper to the safety position. It is equipped with 2 position auxiliary switches and 230VAC powered. GNA326.1E also comes with or without temperature monitoring unit.
