Test voltage input to actuators and repair as necessary if voltage is not correct. Old breakers often deliver below 115V and failed actuators may be due to power supply problems. A record of all repairs must be kept and made available to AHJ. INSTRUCTION SHEET Replacement of Multiproducts motors with Belimo FSxx Series... -
Page 4: Local Code Approval
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. -
Page 5: Cross Reference
A general rule of thumb is that the FSLF replaces motors on dampers 3 sq.ft. and smaller and the FSNF replaces motors on dampers greater than 3 sq.ft. The Belimo FSLF has passed UL555S testing at larger sizes; however, with age and corrosion, it is best to be conservative. -

As with the other examples above, remove the old motor, linkage and spring. Mount the Belimo over the shaft. Other examples are shown above. The arrow points at the spring in the right photograph.

Page 9: Shaft Springs And Fusible Links
In above examples, the extraneous parts are removed and the Belimo dropped onto the damper shaft. Shaft Springs and Fusible Links In the examples below there is a spring wrapped around the damper shaft with a fusible link holding it (arrows). The link prevents the spring from slamming the damper blades closed. -

If they are intact then a kit is available from Ruskin. See below. If the springs are not intact, then the rod can be replaced with ones made by a machine shop. A Belimo BAE 165 US sensor can be installed. This upgrades the damper to modern standards. Call for information. -

NOTE: If the damper shaft bearing does not hold the shaft firmly, then a Belimo FSNF should be used with a leg kit, ZG-AF. The actuator then serves to hold the jackshaft steady. On small dampers, it may be necessary to extend a flat plate out in the air in order to mount leg kit.

Use it as a basis for any of the other wiring schematics. Note that the alarm connections are not touched when replacing an actuator. This is a major concern for Fire Marshals.

There is no electric sensor in the damper in that case as there is typically a shaft spring performing the fire function. Wiring is shown to right.
