As standard, all fire dampers are designed and certified to comply with EI-S performance attributes. PK-I fire dampers are intended to be embedded into fire partition walls. Installation of these units is described in the Installation, Operation and Maintenance manual for square and circular fire dampers PP28_PKI-R_S_EN.pdf. As standard, all dampers can be supplied with a manual actuator, optional accessories, e.g. microswitches, electromagnets, or a servo-driven actuator and communication control units. Detailed description regarding individual models can be found in TPI28_PKI-R_S_EN.pdf.

 

Servo-driven Fire Dampers
Fire dampers can be equipped with a servo that closes the damper blade on demand of the Building Management System or based on a signal received from the thermoelectric fuse or through the use of smoke detectors. Servo fitted fire dampers are standardly equipped with an electrothermal fuse which, when having reached or exceeded the ambient temperature of 72°C with a tolerance of ±1.5°C, activates the servo and closes the damper blade within 20 seconds.

 

Function
The function of the fire damper is to stop the spread of fire, flames and smoke.


Design
Fire damper casings are made of galvanized steel sheets and the blades are made of calcium silicate boards (asbetstos free).
