This insures onsiteperformance equal to test results.• Multi-Section units can be ordered with afusible link and locking hard quadrants.• Also available are options EFL (Electric FusibleLink) and PFV (Pneumatic Fusible Valve). Theseoptions provide quick and economical ways tocheck damper operations and also provide aSystematic Closure Control. Option PFV allowsdamper operation without the need/cost for an E-P valve and electrical connection at the damper.16”StandardLISTED AND LABELLED BY:DESIGNED AND TESTED IN ACCORDANCE WITHUL-555 AND ULC-S112.
