NOTIFIER Monitor Modules FMM-1 Monitor Modules

The NOTIFIER Monitor Modules FMM-1 is a key device in fire alarm systems, mainly used for monitoring specific equipment and providing status feedback. Here is a detailed introduction:

General Overview

The FMM-1 is a multi - input monitor module. It is designed to monitor the status of multiple dry - contact devices simultaneously within a fire alarm system. This module can be connected to various types of equipment, such as smoke detectors, heat detectors, and other sensors, to continuously monitor their working conditions.

Features

Multi - Input Capability: The FMM - 1 can monitor up to four different dry - contact inputs. This allows it to handle multiple monitoring points simultaneously, reducing the number of modules required in the system and simplifying the overall wiring and installation.

Reliable Monitoring: It uses advanced sensing technology to accurately detect the status changes of the connected devices. Whether it is the activation of a detector due to a fire - related event or a normal operational status change, the FMM - 1 can promptly sense and report these changes to the fire alarm control panel.

LED Indication: For easy visual inspection, the module is equipped with four individual LED indicators, one for each input channel. The LEDs provide clear visual cues about the status of each monitored device. For example, a lit LED may indicate that the corresponding device is in a normal working state, while a flashing LED could signal an alarm or a fault condition.

Addressable Functionality: Similar to other NOTIFIER modules, the FMM-1 is addressable. It can be assigned a unique address on the fire alarm system's communication bus. This enables the fire alarm control panel to precisely identify the status of each input channel of the FMM-1, facilitating efficient system management and troubleshooting.

Technical Specifications

Power Supply: It operates on a low - voltage DC power supply, usually in the range of 12 - 24 VDC, which is supplied by the fire alarm control panel through the communication bus. This ensures stable and reliable power supply for the module's operation.

Input Characteristics: The FMM - 1 accepts dry - contact inputs, meaning it can monitor the open - circuit or closed - circuit status of the connected devices. The input impedance is designed to be compatible with a wide range of sensors and devices, ensuring reliable signal detection.

Communication Protocol: It complies with the specific communication protocol of the NOTIFIER fire alarm system. This allows seamless integration and reliable communication with the fire alarm control panel and other system components, ensuring accurate and timely transmission of monitoring data.

Operating Temperature Range: The module is designed to operate within a wide temperature range, typically from - 10 °C to 50 °C. This wide temperature tolerance ensures that the FMM - 1 can perform stably in various environmental conditions, from cold storage areas to relatively warm indoor environments.

Humidity Range: It can work in an environment with a relative humidity of 5% - 95% non - condensing. This makes the module suitable for use in different climatic conditions, whether it is a dry desert - like environment or a humid coastal area.
