SC-HCNT Serial Hall Call Node Board
In a typical installation, an SC-HCNT Serial Hall Call Node board is mounted in each hall call
fixture enclosure. Please refer to “Hall Call Installation” on page 5-32. The board provides two
outputs to power the hall call lamps or LEDs, two inputs for the hall call buttons, and jumpers
to set the floor ID and hall call “type”.
