The digital display clocks can be used as a stand-alone system or as a secondary to virtually any master controlled system. This flexibility allows you to install additional clocks or replace old clocks in an existing analog system.

The four-digit display is highly visible from 100 feet and can be mounted directly to the wall or to a single gang outlet box. With other kits, it can also be dual wall or dual ceiling mounted. A vented hole is provided for 1/2-inch conduit. During power failures a 9-volt alkaline battery provides continuous timekeeping. When power resumes, the display illuminates the correct time.

Features:
Operates as a secondary clock to virtually any master controlled system.
Available in 115V or 24V models.
New 2-inch display model is ideal for smaller office and classroom environments.
Large 4-inch tall digital display model is highly visible from 100 feet.
Ability to count-up and countdown using the DDC-TC Timer Control sold separately.
Selectable time display is 12 hours and minutes with PM indicator or 24 hours and minutes.
During power failures a 9 volt alkaline battery provides power to continue timekeeping.
When power resumes, the display illuminates the correct time.
Can be directly mounted to the wall or mounted to a single gang outlet box
With optional kits, clocks can be dual wall mounted or dual ceiling mounted.
A vented-hole plug is provided for 1/2 inch conduit.
A standard RS485 port allows automatic correction from Lathem’s:
Install additional clocks or replace worn clocks in an existing analog system.
Optional: LTR-GPS can synchronize a network of up to 31 DDC-Series clocks to an ‘Atomic’ reference.
Optional: DDC-TC Precision timer control allows you to use your Lathem digital wall clock for counting and timing applications.
