Local Code Approval
While it is not detailed in codes, the following rules should be followed for selecting Belimo
actuators for replacement:
Check the technical specifications to ensure an "equal or better" actuator is used.
• Temperature – the replacement actuator shall have been UL555S tested at the same or
better temperature as the original actuator. 250˚F or 350˚F are standard.
• Time – the replacement actuator shall drive open and spring closed at a speed equal or
faster than presently required by codes. (The AHJ may grant an exception and
"grandfather" slower actuators where the original actuator was slower.)
• Torque – replacement actuator shall have equal or greater torque than the failed actuator.
• Voltage – replacement actuator shall have the same voltage rating as the original.
• Amperage – the replacement actuator(s) shall not draw more amperage than the
original(s) and cause the total connected amp draw on a circuit breaker to be greater
than allowed by electrical code.
• Final Testing – actuated damper and associated devices shall be tested for proper
operation. See Acceptance testing details below.
In all cases, installation must comply with any and all local electrical
and life safety codes. Operation of the system after installation must
be performed to verify proper damper cycling. Final checkout requires
verifying correct function.
Note that where any fire alarm wiring is touched, the fire department
must be informed.
