1.3.3 Model 13-14 – Type 3 – Type 2 System with Controlled Electrical Dampers
This system takes the Type 2 approach a step further, making the start/stop damper interlock an inher-
ent feature and providing power to electrically-operated/spring-return dampers. The first damper to
open causes the fan to start; the last one to close causes it to stop. AMU or other start interlocks are
also provided.
Up to six dampers may be accommodated with a standard system – more are available on special order.
