Smoke damper S-SA1

Overview
S-SA1 smoke control dampers are rectangular dampers designed to operate with mechanical or natural smoke and heat extraction systems. They enable removal of smoke and toxic gases and can also supply clean air to fire compartments. The dampers are actuator-operated (no spring) and provide defined open and closed safety positions. Electrical power is required for actuator operation.

Key features

• Versatile
• Duct installation (for ducts terminating with a grille)
• Galvanised sheet metal casing
• Provision of clean air to fire compartments

Benefits

• Compatibility — Designed to operate with mechanical or natural smoke and heat extraction systems.
• Actuator operated — Supplied with an actuator without a spring; provides defined open and closed safety positions.
• Duct installation — Intended for duct installations finishing with a grille (not suitable for direct wall or ceiling installation).

Materials and construction

• Casing: galvanised sheet metal
• Blades: calcium silicate boards
• Seals: silicone rubber gasket to minimise smoke/heat leakage

Installation notes
S-SA1 dampers are designed for duct installations that terminate with a grille; they are not suitable for wall or ceiling mounting. A power supply is required to operate the actuator.
