Description

The Bosch D7053 MUX input/output module (12V) is a general-purpose device that monitors a normally-open (NO), supervised contact device. It provides a separately controlled Form C relay output. The module connects to the multiplex bus of an FPD-7024, D7024 or DS9400M FACP. It configures as either Class A or Class B and addresses using rotary switches. All operating power for the module is drawn from the control panel’s multiplex bus. An on-board status LED indicates normal, alarm, and trouble conditions.

The Bosch D7053 is compatible with the FPD-7024, D7024*, and DS9400M* Fire alarm control panels. The modules connect to the FACP through an expansion module. Use the FPE‑7039 with the FPD-7024 FACP or the D7039* with either the FPD‑7024 or D7024* FACPs. Use the DS9431* Multiplex expansion module with the DS9400* FACPs.
