The FMM‐7045 MUX manual stations are UL Listed fire alarm initiating devices. They can be connected along with other multiplex (MUX) devices on the FPE-7039, D7039, DS9431 MUX expansion modules. The FPE-7039 or D7039 are used with the FPD‐7024 or D7024 FACPs.

The DS9431 is used with the DS9400 FACPs. The FACPs supervise the entire MUX loop, including the manual stations, for troubles, alarms, and ground fault conditions. Each manual station occupies only one address on the MUX bus. A manual station can be addressed for any point within the MUX module’s 9 to 255 range. A manual station is generally installed near building exits, allowing persons evacuating the building to activate the fire alarm. 

They have optional scored acrylic break rods and a pull handle that locks in the activated position. These features allow easy identification of alarm activation points. The manual stations have a low profile and rounded edges to fit most design applications. They are manufactured in conformance with the standards set forth in the Americans with Disabilities Act (ADA). All components are painted or have plated surfaces to inhibit corrosion. Non-corroding screw terminals are provided for wire connections.
