Its side-mountable design optimizes installation flexibility, especially in constrained spaces. Manual control is available through a built-in handwheel for power outages. Rated IP54 and operable from -30°C to +60°C, it supports remote operation, LED indicator boom integration, and compatibility with fire alarm triggers.
