Bosch DS7465I

The Bosch DS7465I is a single input/output module for multiplex fire alarm and security systems, using two multiplex zone addresses to supervise one power-limited input zone while providing one DIP-switch-programmable Form C relay output. Designed for UL-listed fire and security applications, this module activates its output relay on various system events—alarm, supervision, or other configured triggers—and supports standard contact supervision with normally-open (NO) or normally-closed (NC) contacts. The DS7465I enables flexible integration of auxiliary devices, remote annunciators, or zone-level control logic into multiplex systems, with support for up to sixty modules on a compatible control panel.
