MAx-31x-x-x-4 and MAx-41x-x-x-4 series actuators provide significantly improved high temperature exposure

performance for use in smoke or fire dampers, or combination smoke and fire dampers. Refer to Engineering

Information EN-216 (UL 555S), F-27068.

Class 1, Groups C & D, and Class 2, Groups E, F, and G hazardous locations; refer to EN-56-2.

Models for hazardous locations are only available as factory-built enclosure/actuator assemblies.
