All the Disys Technologies nodes are micro-controller based intelligent devices which monitor the status of other elements of the damper control system and broadcast status information to the network.
- DIN 12
- The DIN 12 is most commonly used as the fire/smoke damper control node. Available to control either 230V ac or 24V ac/dc actuators, it also monitors the status of the actuator limit switches.
- DIN 08F
- The DIN 08F provides 8 opto isolated zone alarm inputs to the damper control system from fire alarm system relay outputs.
- DIN 24A
- This variant is most commonly used as an interface between the damper control system and AHU's. It provides the facility to shutdown the AHU in the event of a fire and then to override it via the fireman's override switches.
