DESCRIPTION
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
120VAC 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.

Installation Instructions
INSTALLATION
The Model 349 Override Timer has 4” wire leads for AC
power connections.
For 24VAC operation, connect power to the WHITE
and RED leads. Cut back the unused BLACK lead and
cover with a wire nut.
For 120VAC operation, connect power to the WHITE
and BLACK leads. Cut back the unused RED lead and
cover with a wire nut.
The Model 349 has 4” wire leads for load circuit
connections. These are color-coded as follows:
YELLOW.....Relay Common
ORANGE....Normally Open
BLUE.....Normally Closed
Connect the appropriate wires into your circuit wiring
and secure with wire nut. When used to turn a load on
for a timed period, the yellow and orange leads will
be used.
To turn a load off for a timed period the yellow and
blue leads will be used.
Unless both the open and closed contacts are being
used in the same circuit, the unused lead should be cut
back and covered with a wire nut to prevent its shorting
to the mounting box. Secure the Model 349 in a
standard switch box (at least 3” deep) and apply power.
