Compumatic MP550 Synchronized Time Clock & Bell Kit

Description

The MP550 synchronized bell kit is an electronic punch clock system designed to record employee time while automatically activating a connected bell at scheduled times. It is built around the Compumatic MP550 front-loading time clock and is used to automate shift changes, breaks, and lunch periods without requiring software, networking, or external timers. Scheduling is handled directly within the clock, allowing stand-alone operation.

This configuration includes the MP550 time clock with a factory-installed signal kit, external power supply, wiring, and a 110V bell depending on package selection. Once programmed, the clock sends an external signal to the bell at scheduled times, creating a consistent audible alert across the work area. Signal duration can be adjusted through the clock’s internal programming, allowing different alert lengths for warning signals or shift changes. The optional signal circuit enables external signaling through the clock’s internal timing controls rather than a separate timer. :contentReference[oaicite:0]{index=0}

The MP550 platform is commonly used where a simple time card system is preferred but audible shift signaling is also required. Typical installations include shops, warehouses, maintenance departments, and small production areas where employees may not always be watching the clock. The integrated signal board keeps both time recording and signaling controlled from a single device, simplifying installation and reducing system complexity.
