LTR Series Master Controls

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). All models in the series support Lathem's DDC-series Digital Clocks via RS485 network cable. Additionally, The Model LTR4-512 has a capacity of four bell circuits, or one clock system (any of over 50 makes / models) and two bell circuits. The Model LTR8-512 can support either 8 bell circuits, or one clock system and six bell circuits, or two clock systems (any 2 of 50+) and four bell circuits. It can load and 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 LTR8-512 series models are also compatible with the LTR-RSS Remote Schedule Selector, which is particularly well suited to school applications.
