Lathem LTR4-512 Master Control - 1 Clock + 2 Signal Circuits (or 4 signal only). Lathem Master Controls are ideal for schools, hospitals, airports and industry. With Lathem's wall clocks, the Master Control series can improve attendance, organize schedules and increase efficiency. The system can be programmed, via keypad, with eight password-protected bell schedules, which may be used in combinations; each capable of executing 64 multi-function "events" (512 aggregate). There are two models, LTR4 (4 circuits) and LTR8 (8 circuits). It can store schedules and controls from any RS232 / RS485 connected computer running Lathem's MasterLink Software, or can be accessed and diagnosed remotely, via modem (Model LTR8-512M). The LTR Series controls virtually any type of secondary clock system. Lathem manufactures both synchronous and minute impulse secondary wall clocks in a variety of shapes, sizes and clock dial types.
