GTS-2
The GTS-2 can be used with combination fire smoke dampers equipped with Greenheck’s TOR option. The GTS-2 has a key switch with red indicator light for closed damper, green for open damper. The GTS-2 has a three position control switch with the following options:

  • Normal position – power is routed to the actuator through the primary, low-temperature, thermostat
  • Closed position – power is cut to the actuator closing the damper
  • Override position – power is routed to the actuator through the secondary, high – temperature, thermostat. This position is used to reopen the damper for smoke control purposes after the damper’s primary thermostat has tripped and closed the damper. The damper will close when the secondary thermostat’s temperature is reached, when a smoke detector senses smoke or when power is cut by a smoke or building management system.
