Code and Standard Issues
In general, the administrative section of codes state that all mechanical and electrical systems
must be kept in working order and an individual section may state that all life safety devices and
systems must be operable. NFPA 80 (Fire) & NFPA 105 (Smoke) require periodic testing and
repair of dampers as soon as possible after any deficiency is uncovered.

Not required
Fire & smoke dampers are appliances and field replacement of components is required when
failure of any component occurs.
The Authority Having Jurisdiction (local Fire Marshal and/or Building Official) must be
consulted if any blade or auxiliary switches are employed and are connected to the fire
alarm system or to a Fire Fighters Smoke Control System (FSCS) panel. Retesting is
required. A permit and inspection may be required since connections to an alarm system
have been touched
.
In the “Marking & Application Guide, Dampers for Fire Barrier and Smoke Applications &
Ceiling Dampers” April 2013 by Underwriters Laboratories Inc.®, page 6 they state:
DAMPER ACTUATORS
“… field mounting or substitution of actuators is not covered within the scope of the UL
certification of the product. However, this does not necessarily preclude replacement of
ac•tuators in the field. Like any appliance, field servicing of these products is not covered
under the scope of the UL certification and factory follow-up service program. As with any
part of the damper, it is expected that replacement of actuators in the field be done in
accordance with the damper manufacturer
’s
normal field servicing program.”
