Bosch’s D7053 Multiplex Input-output Module is a general purpose device that monitors a normally-open (NO), supervised contact device and provides a separately controlled Form C relay output. The D7053 connects to the multiplex bus in either a Class A (Style 6) or Class B (Style 4) configuration. All operating power for the D7053 module is drawn from the control panel.
The D7053 MUX I/O Module is designed for use with Bosch’s D7024, DS9400M, or FPD-7024 addressable FACPs.
Mounts to a standard double-gang or four-inch square back box.
