Bosch D7052

The module connects normally‐open (NO) contacts to the multiplex bus of an FPD‐7024, D7024, or DS9400M FACP. Use the module for two Class B supervised inputs or one Class A input. All operating power for the input module is drawn from the FACP. Rotary switches allow convenient address setting. A status LED indicates normal, alarm, and trouble conditions. The LED is visible on the module or on a low‐profile faceplate.
