Description
The Notifier DS-SFM is a single-mode fiber option module designed to convert digital audio ports on compatible NOTIFIER emergency voice systems from copper wiring to fiber-optic communication. It extends Digital Audio Loop (DAL) communication distances while maintaining reliable audio data transmission between DAA2, DAX, DS-DB, and DVC system components. The module is used in large-scale fire alarm voice evacuation systems requiring long-distance fiber connectivity.

Information About DS-SFM
The DS-SFM is part of the NOTIFIER Digital Audio Loop fiber option module family, developed to provide single-mode fiber communication capability for emergency voice evacuation systems. The module installs into compatible DAA2, DAX, DS-DB, and DVC devices, converting one digital audio port from wired communication to fiber optic transmission. It supports mixed-media DAL networks where wire, single-mode fiber, and multi-mode fiber segments can operate together within the same audio loop architecture. The DS-SFM is designed for DVC-based emergency communication systems where extended distance, reduced signal interference, and reliable audio distribution are required.
Key Features:
- Single-Mode Fiber Conversion: Converts one digital audio port from copper wiring to single-mode fiber communication.
- Digital Audio Loop Support: Enables fiber integration within NOTIFIER DAL emergency voice communication networks.
- Extended Communication Distance: Allows longer digital audio runs compared with traditional copper wiring.
- Compatible Host Devices: Designed for use with DAA2, DAX, DS-DB, and DVC systems.
- DVC Compatibility: Supports DVC systems requiring DVC-EMPCC version or later.
- Mixed Media Networking: Allows wire, single-mode fiber, and multi-mode fiber segments on the same Digital Audio Loop.
- Flexible Installation: Supports installation of one or two fiber option modules in compatible devices.
- Fiber-Based Communication: Provides reliable transmission using single-mode fiber optic cable.
- Reduced Signal Interference: Fiber communication improves resistance to electromagnetic interference in demanding environments.
- Emergency Voice Integration: Supports distributed voice evacuation and mass notification system architectures.
- Modular Expansion: Enables partial or complete conversion of digital audio networks to fiber communication.
- System Compatibility: Integrates with NOTIFIER ONYX® fire alarm voice evacuation solutions.
The DS-SFM delivers the reliability and precision required for fiber-based emergency voice communication and digital audio loop expansion.
