The Model 349 Series Override Timers are one-shot timers designed as lighting control timers or override controls for energy management applications. The timers are designed to operate from either 24 or 120 VAC and mount in a standard wall switch box. Wire leads allow connections to be made with wire nuts.
The Model 349-2 is a 2-hour timer adjustable from 5 minutes to 2 hours. Pressing the start button pulls in the internal relay. After the delay, the relay drops out. pressing the button again during the delay period will restart the timer. An indicator light shows when the relay is pulled in.
The Model 349-5 has a maximum delay of 75 minutes in 5 minute increments. The Model 349-15 has a maximum delay of 15 hours, in 1 hour increments. The 349-15 can also be set to 15 minute increments (3 ¾ hours maximum delay).
On both models (349-5 and 349-15), after the start button is pressed, the internal relay pulls in for one timing increment. Each additional press of the button adds one timing increment to the time, up to 15 increments total. The 16th press of the button drops out the relay. Binary numbered indicator lights show remaining time.
