B228 SDI2 8-Input, 2-Output Expansion Module

The B228 SDI2 Expansion Module offers enhanced flexibility for intrusion alarm systems by providing 8 supervised input zones and 2 independently switched outputs. Designed for easy integration with control panels via the SDI2 bus, this module enables precise monitoring and control, communicating all status changes back to the control panel for real-time system updates. Ideal for expanding zone coverage, it simplifies complex setups by using onboard screw terminals for secure connections and supports up to 16 zones through double wiring.

Engineered with durability and functionality in mind, the B228 module supports versatile loop configurations, detecting open, short, normal, and ground fault conditions across each sensor loop. Each loop is assigned a unique zone number for accurate tracking. The module includes a tamper switch connector, a power state indicator LED, and configurable outputs that can be set to trigger based on specific system events, ensuring maximum control over integrated security systems.

  • 8 programmable input zones with supervised loop monitoring.
  • 2 configurable switched outputs with shared +12V terminal.
  • Power and status LED indicators for quick monitoring.
  • Compatible with a range of loop resistances for flexible configurations.
  • Supports both Normally Open (NO) and Normally Closed (NC) contacts, with split EOL options.
  • PRODUCT TYPE INPUT/OUTPUT EXPANDER
