Large sites defeat wireless call systems. A signal that works across a single wing drops out by the time it reaches the far end of a second building, and the call point that matters most is usually the one furthest away.
The slave zone repeater extends a Cura1 Long Range Call System across that distance. It talks to the master zone repeater under full wireless supervision, which means the system knows if a repeater stops responding, so coverage is never lost silently. Each repeater monitors its own set of wireless call points, and a system can carry a large number of them, so coverage grows with the site.
It is hardwired for power and can take an internal rechargeable backup battery so calls keep flowing through an outage. Status LEDs on the front let maintenance staff confirm it is healthy without opening anything.
This is facility infrastructure.
