The American Time U55BABA532X is a 12-inch round double-dial AllSync Plus wired analog clock. It is a direct drop-in replacement for the Simplex 6310-9239 12″ round synchronized clock.
First, the U55BABA532X reads the time-correction signal from your existing wired master clock. Then it adjusts itself automatically — no manual setting after install. As a result, every clock in the building shows the same time, accurate to ±1 second of the master.
The movement is solid-state, not mechanical. Therefore, it uses up to 80% less energy than the original Simplex motor. In addition, fewer moving parts means fewer wear-out failures and a quieter clock.
Why the American Time U55BABA532X Replaces a Simplex 6310-9239
The U55BABA532X is engineered as a wired-sync replacement for legacy OEM systems. Specifically, the on-board circuit reads the Simplex 3-wire secondary clock correction protocol. As a result, the U55BABA532X drops into existing wiring without changes at the master clock.
Furthermore, the AllSync Plus circuit board is field-jumpered for either 120 VAC or 24 VAC operation. Therefore, the same part number fits both common Simplex secondary clock voltages. Always confirm the jumper matches your system voltage before powering up.
This is the double-dial variant. Therefore, both faces show synchronized time, making it ideal for hallways, corridors, and through-wall mount applications.
Key Features
- 12-inch round double-dial analog clock
- Black plastic case with poly-crystal lens
- Auto-correcting movement reads OEM Simplex 3-wire correction protocol
- Accurate to ±1 second of the master clock
- 15-minute backup keeps time across brief power interruptions
- Solid-state circuit board movement — up to 80% less energy use
- Field-selectable 120 VAC or 24 VAC operation via jumper
- Three-year manufacturer warranty
- Lifetime technical support from American Time
Compatibility
The U55BABA532X replaces the Simplex 6310-9239 12-inch round double-dial clock. In addition, AllSync Plus clocks support six different OEM wired-system correction protocols. Therefore, the same body also serves as a replacement for many other legacy wired master systems beyond Simplex.
Installation Notes
- Verify the supply voltage at the clock leads (120 VAC or 24 VAC) before powering up
- Set the on-board jumper to match the system voltage
- Connect to the existing 3-wire secondary clock circuit — no new wiring needed
- Allow 24–36 hours for the clock to fully synchronize, depending on correction protocol
- Wrong-voltage jumper setting will either blow the on-board fuse (24V jumper on 120V) or starve the board (120V jumper on 24V)
