Test for proper operation using one or more of the following methods.
1.
Manual pull handles: Pull the manual pull handle from the exterior of the smoke vent.
Pull the internal manual pull handle if it has been routed down to the floor level.
2.
Fusible link: Melt the fusible link from the inside at the smoke level using a hand-held
propane tank torch. Make sure to have replaceable fusible links on hand to reset the
latch and close the doors. An alternative method is to remove the fusible link to
simulate melting to verify that the smoke vent would indeed open.
3.
Optional electrical Belimo actuator: Send an electrical signal from the fire alarm, push
button control, or other to validate electrical fire system performance.
MAINTENANCE
•
Manually operate vents once a year to inspect, maintain, and replace components as
necessary.
•
Inspect fusible links for evidence of corrosion, stress/strain or build up. Clean or
replace as required.
•
Nonmoving parts may be cleaned with a mild soap or dishwashing detergent and
water solution.
•
Gaskets should be washed with a clean, damp, lint-free cloth. Do not apply mineral
oils vinyl dressings, or other lubricants to the gasket as they can cause the gasket to
break down over time.
Fusible link ambient temperature rating
The fusible link should be specified with a temperature rating greater than the maximum
ambient exposure temperature that will be seen at the installation.
For example, an “ordinary”
fusible link rated at 165 degrees F has a maximum ambient
exposure temperature rating of 100 degrees F. If this fusible link is routinely exposed to
ambient temperatures over 100 degrees F, it is liable to separate. Select a fusible link rated at
212 degrees F (or greater) for this type of application. See table below to find a fusible link
temperature range compatible with an expected or measured ambient temperature. This is
in accordance with UL guidelines.
