Comelit 1424 Digital Switching Device with Simplebus Top

The Comelit 1424 Digital Switching Device with Simplebus Top delivers scalable, reliable switching for professional intercom and entry systems. Designed for integrators and security teams, it supports up to 120,000 users and can incorporate up to 500 Comelit Simplebus KITS, enabling large-scale access control, surveillance, and visitor management across commercial, multi-tenant, and campus environments. The 1424 allows independent main and secondary switchboards with alarm signaling for clear event routing and rapid incident response, while cascadable bus distribution optimizes cabling and reduces installation time and cost. A self-powering LS|LS input simplifies riser management so you can avoid extra secondary power units; the unit mounts in 4 DIN modules (60 x 85 x 35 mm) and accepts a 12Vac / -20Vdc supply for standard electrical environments. By combining robust networking features with compact, DIN-rail form factor, the Comelit 1424 streamlines system architecture for monitoring, security, and access control professionals.
