About this detail

An addressable relay module mounts inside a four-inch square deep electrical box with four machine screws securing the assembly. A CB500 barrier is included as required for the separation of power-limited and nonpower-limited wiring. A module cover plate fastens over the module using two countersunk screws. The relay module terminals accept Signaling Line Circuit loop wiring in and out, along with connections for system auxiliary inputs such as damper control and elevator recall.
