Notifier FDM-1 Dual Monitor Module

The Notifier FDM-1 is an addressable dual monitor module that monitors and supervises two independent two-wire Style B (Class B) dry-contact initiating device circuits at two separate, consecutive addresses. It is designed for use in intelligent, two-wire fire alarm systems.

Each circuit provides an interface for normally open contact devices such as waterflow switches, pull stations, and supervisory devices. The module mounts to a 4-inch square electrical box, features rotary address switches, and is powered directly by the SLC loop. The FDM-1 is compatible with Notifier intelligent fire alarm control panels using FlashScan or CLIP protocol.
