Digital Security Controls HSM3408 PowerSeries Pro 8-Zone Expander

Add eight wired zone connections to a PowerSeries Pro security system without replacing the primary control panel. This expansion module provides additional points for wiring security devices where the original panel zone capacity has been allocated. Its eight-zone format suits sites that are extending perimeter coverage, adding interior detection, or connecting further supervised field circuits as a system grows. Removable terminal blocks distinguish this module from fixed-terminal expansion hardware. Installers can terminate field conductors at the connector, remove the connector when service access is required, and reconnect it without individually releasing every conductor from the board. That arrangement can simplify cabinet work where multiple zone wires must remain organized during installation, testing, or maintenance. Digital Security Controls HSM3408 is intended for PowerSeries Pro applications requiring a defined eight-zone expansion point with removable field-wire terminals. Use it where added wired inputs are needed close to the control equipment and where serviceable terminal connections matter. The module expands zone capacity rather than serving as a control panel, detector, keypad, or communications device, keeping its role clear within a larger intrusion security installation.
