The Simplex 4905-9903 is an adapter plate (part number 0740640) designed to adapt older Simplex notification appliance mounting footprints to current Simplex 4905-series horn/strobe devices. When upgrading or replacing older Simplex notification appliances, the mounting hole pattern or backbox footprint may not match newer devices — the 4905-9903 bridges this gap, allowing new devices to be installed without cutting new holes or replacing electrical backboxes.
