Hikvision Wired Input Expander (Cascade) | DS-PM1-I8O2-H

The Hikvision DS-PM1-I8O2-H is a Speed-X wired zone expander for the Hikvision AX Hybrid Pro control panel. It adds 8 on-board wired zones and 2 on-board collector outputs, and it can be installed up to 900 m from the control panel. A second Speed-X bus lets you cascade the next expander another 900 m away.

8 Wired Zones: The expander adds 8 on-board wired zones to the AX Hybrid Pro system. Each zone supports alarm, tamper, masking, fault and short detection, so the panel can tell a real alarm from a wiring problem.

3EOL Connection: Zones support 3EOL wiring with 1 kΩ for alarm, 1 kΩ for tamper and 2.2 kΩ for fault. This lets each zone report alarm, tamper and fault states separately over the same pair of wires.

2 Outputs: 2 on-board collector (IO) outputs are provided for connecting a relay module.

Speed-X Bus and Cascading: The module communicates with the control panel over the Speed-X bus at up to 900 m. Its second Speed-X bus output cascades the next zone expander, with up to another 900 m of cable.

Power for Detectors: 1 power output supplies wired detectors with 9 to 12 VDC, up to 500 mA, so nearby detectors can be powered from the expander.

Tamper and Status: Front and rear tamper protection reports attempts to open or remove the module, and LEDs show power and fault status.

Who it's for / Works with

Hikvision AX Hybrid Pro control panels, over the Speed-X bus. Hikvision lists it for small to medium sites such as villas, shops, offices and hotels.

Good to know

Needs an 11 to 24 VDC power supply (12 VDC typical).

Operating temperature is -10 °C to 40 °C, so the module is meant for indoor installation.
