TPM 140/19
I. GENERAL
Description
Fire dampers are shutters in ducts of air-conditioning devices
that prevent the spread of fire and combustion products from
one fire segment to the other one by means of closing the
duct in the points of fire separating constructions.
Damper blade automatically closes air duct using a closing
spring or a spring return actuator. The closing spring is
actuated by pressing a button on the manual control or by
melting a thermal fuse.
The return spring of the actuator is actuated when a
thermoelectric activation device BAT is activated, when a test
button on BAT is pressed or when power supply of the
actuator is interrupted.
After closing the blade, the damper is sealed with silicon
against smoke penetration. On request by customer, the
damper can be supplied silicon-free. In the closed position,
the damper is also sealed with material which increases its
volume due to increasing temperature and air proofs the air
duct.
Working conditions
■ Exact damper function is provided under the following conditions:
■ maximum air velocity 12 m/s
■ maximum pressure difference 1200 Pa
■ the air circulation in the whole damper section must be secured steady over the entire surface.
■ Dampers can be installed in position with horizontal or vertical blade axis.
■ Dampers can be installed in position with actuating mechanism on top or on the side of the damper.
■ Dampers are suitable for systems without abrasive, chemical and adhesive particles.
■ Dampers are designed for macroclimatic areas with mild climate according to EN IEC 60 721-3-3 ed.2., class 3K22.
(Environment 3K22 is typically protected place with regulated temperature)
■ Temperature in the place of installation is permitted to range from -30°C to +50°C.
