The Simplex 743-182 is a Simplex 4004R system board and upgrade kit. As a result, it lets a service technician restore or refresh the core electronics inside a Simplex 4004R fire alarm control panel.
Specifically, the kit supplies the replacement system board for the 4004R platform. In addition, it is intended as a like-for-like service part for facilities still operating Simplex 4004R panels.
Where the Simplex 743-182 Fits
The 4004R is a small-footprint conventional Simplex panel. First, identify the panel as a 4004R (not the addressable 4004 variants). Then, plan the board swap during a scheduled outage. Therefore, the building remains under fire watch only briefly.
Also, this is a common spare for older Simplex installations in low-occupancy commercial buildings. Furthermore, the part is sold for service replacement, not for new construction.
