Product Description: This SuperBus 2000 8-Zone Input Module adds eight supervised hardwire zones. The module includes mounting hardware and eight 2.0K ohm end-of-line (EOL) resistors. Power for the module is provided by the security panel. Both normally open and normally closed detectors can be wired to module inputs. Using an EOL resistor on each loop input, the module monitors all zones and alerts the panel if there is an open/short circuit. Advent panels can support multiple modules for up to 250 zone inputs. UltraGard panels can support up to eight modules for 64 additional zone inputs. Concord panels can be expanded up to 76 zone inputs. For additional security, the plastic case includes space for installing a magnet and reed switch that can provide tamper protection to detect cover removal.
