The TS150 is a UL Classified heat responsive device which is used in conjunction with Lau fire/smoke dampers. The TS150 is an optional device which can be ordered with electric actuators or pneumatic actuators and EP (electro/pneumatic) switches. The TS150 allows the dampers to be reopened after the initial closure for dynamic smoke control. The TS150 must be installed at the factory and cannot be added in the field. Replacement TS150’s may be field installed with the approval of the local authority.
