Belimo BAE72B-S Thermoelectric Tripping Device

Belimo BAE72B-S Thermoelectric Tripping Device - ApplicationThe BAE72-S Thermoelectric tripping device operates in conjunction with a spring-return actuator to drive a motorized fire damper to its "safe" position in the event of the preset maximum temperature being exceeded. The device is normally connected to the BKN230-24... communications and power unit. In systems with no such unit, the BAE72-S device is connected in series with the power supply of the spring-return actuator (use only 24V actuators).Mode of operationThe BAE72-S tripping device employs three thermal trips Tf1, Tf2 and Tf3. Thermal trip Tf1 operates if the ambient temperature exceeds 72C. Replaceable thermal trip Tf2/Tf3 operates if the temperature inside the duct exceeds 72C. Tf1, Tf2 or Tf3 trips cause the power supply to be interrupted permanently so that it cannot be uncancelled. If the power supply is interrupted, the energy stored in the spring moves the damper back to its safe position. - Belimo - Belimo - BAE72B-S - BAE72B-S
