Simplex 478-332 Legacy Module for Simplex Fire Alarm Panels
14 in stock
The Simplex 478-332 is a legacy module for older Simplex fire alarm control panels, supporting service and retrofit work on installed systems that predate the current IDNet2 platform.
Compliance
- Designed for use within UL 864 listed Simplex fire alarm control panel assemblies
- NFPA 72 National Fire Alarm and Signaling Code installations
- FM Approved system context (panel dependent)
Key features
- Board-level module for legacy Simplex panel configurations
- Intended for repair, retrofit, and like-for-like replacement on installed systems
- Mounts in the original board position within the host panel chassis
- Supports continuity of existing fire alarm infrastructure without a full panel swap
- Specified by Simplex part number to match the panel revision in service
- Used in commercial and institutional buildings running earlier Simplex platforms
Earlier Simplex panels were assembled from discrete boards on a modular chassis, each handling communication, monitoring, or control on conventional and early addressable circuits. Matching the original part number keeps the installed system aligned to its listing, and replacing a single board rather than the whole panel lets a facility defer a larger migration while the platform remains in active service.
