The LVN20S provides a unique solution to the problem of containing both fire and smoke in emergency conditions yet offering good air transfer through doors in everyday use. Using the same intumescent louvred slat configuration as the LVN20 but incorporating an electro mechanically operated smoke shutter mechanism. Can provide up to 60 minutes fire and smoke resistance

Simple installation.
Auto reset plus failsafe.
Safe low DC voltage.
Status reporting plus auto-cycling via Talkback Damper Control Monitor (DCM).

Use with talkback damper control system. Conductor hinges. Optional Alarm Monitoring System (AMS) and battery backup.
Other non-standard sizes may be available - consult the manufacturer for details.
Each damper is manufactured 2 mm less than a nominal aperture size to provide clearance when installed in a duct or other aperture of the same nominal dimensions. e.g. a 198 x 198 mm nominal size damper will suit a 200 x 200 mm aperture. Screwed into door with an aperture lined with Lorient intumescent liner (B24402).
