Typical Specification
Where indicated on drawings, combination fi re and smoke and balancing dampers
shall be controlled by Belimo FSAF24-BAL or equal actuators. The actuators must
be designed so that they may be used for either clockwise or counter clockwise
failsafe operation. Actuator shall open damper in <75 seconds per UL555S and shall
spring closed in under 20 seconds. Actuators shall have a 5-year warranty and be
manufactured under ISO9001 International Quality Control Standards.
Actuator shall have an adjustable Maximum Opening Potentiometer which shall be
used by the TAB contractor to adjust fl ow to that portion of the system fed by the
damper.
The actuator shall spring closed if either the smoke detector or alarm system
removes power from it. Actuator shall spring closed if the primary temperature
thermodisc opens due to high ambient of >165°F or as otherwise indicted on
drawings.
The actuator shall drive full open if either the smoke control system 100% open
override or Fire Fighters Smoke Control Station override is activated. Damper shall
spring closed again if the thermodisc of a combination fi re and smoke damper opens
due to high temperature (typically 250°F).
