Overview of Hikvision DS-PM1-I8O2-H
The Hikvision DS-PM1-I8O2-H is a wired input expander that adds 8 wired zones to a Hikvision hybrid alarm panel. It supports 3EOL wiring (Alarm 1KΩ, Tamper 1KΩ, Fault 2.2KΩ) for detecting zone alarm, tamper, masking, fault and short circuits, giving installers better line supervision. Two Speed-X bus ports, one input from the control panel and one output for the next expander, allow cascade wiring across large sites. It also provides 2 IO outputs for relay modules and a power output of 9 to 12 VDC up to 500 mA for wired detectors. It suits large villas, compounds, schools, factories and warehouses with many wired zones.
