Alpha IS407S 4-Wire Apartment Intercom Station, Stainless Steel

Built to protect entry points and simplify tenant communication, the Alpha Communications IS407S 4-Wire Apartment Intercom Station provides rugged, vandal-resistant performance for multi-tenant security and access control. The .035" thick stainless steel faceplate and metal push-buttons minimize damage and maintenance costs, while the high-sensitivity 2.75" (70mm) speaker ensures clear voice transmission and reliable tone signaling for visitor screening and monitoring. Designed for quick surface mounting onto finished walls, the IS407S can also be fitted to the included BP407S steel backplate for added security or uneven surfaces—making installation straightforward in apartments, condos, and managed housing. Color-coded pigtail wiring resists corrosion and reduces installation time compared with printed circuit board designs. As a wired 4-wire apartment intercom, it supports a wide range of access control accessories such as multi-entrance operation and delayed or silent door releases, allowing easy integration into broader security and surveillance systems.
