Siemens FDM230 Fire Door Monitoring Device

1. General Description

The Siemens FDM230-CN Manual Alarm Button is a device from the Siemens 720 series. People use it for manual fire alarm activation and for monitoring fire doors. It meets the GB19880-2005 standard for "Manual Fire Alarm Button." Part of Siemens’ reliable 720 series fire safety line.

The SIEMENS FDM230-CN manual fire alarm has two functions. It works as a manual fire alarm call point and a door monitoring unit. It consists of two primary components: the manual call point (hand report) and a base. When pressed, it manually initiates a fire alarm signal, allowing rapid human intervention during fire emergencies.

Each FDM230-CN unit has its own address. The system sets this address automatically, so you do not need an encoder or DIP switch. It communicates directly with Siemens controllers such as the FC720-CN and FS1120 series via C-NET communication. The device has a built-in 3.5 mm phone jack for direct communication in emergencies.

It also includes a tear-off coding sticker on the product label. This sticker makes engineering installation and debugging easier.

The FDM230-CN offers a resettable press-type design, allowing easy restoration after activation. Siemens offers an intelligent fire detection system. It works well with other parts, like the FDHM230-CN Hydrant Manual Call Point and FDM223-EX models. This helps ensure complete fire safety management in buildings.
