Description

The Bosch FLM-325-IM Contact Module provides a variety of fire alarm functions, such as monitoring manual pull stations, waterflow devices, or other dry contact fire alarm activation applications. It also allows for alarm, trouble, and supervisory conditions. The Bosch FLM-325-IM is mounted inside of a single‑gang backbox and is normally out of view. The module allows compatible fire alarm control panels (FACP) to supervise Form A or B dry contact devices in a polling circuit, and has an eight‑bit microprocessor and communicates with the control panel (both power and data) over a two-wire polling circuit. The initiating device circuit (NFPA Style B) connected to the module can have up to 20 normally open (NO) dry contact devices. Each module can monitor one normally-closed (NC) device (NC devices must be non-alarm applications).
