Warnings
All units are recommended for indoor use, not for outdoor use. Unit must be tested periodically
to verify the life of battery. STI recommends you change the 9 Volt battery twice a year.
Installer may need to purchase a simple audio-meter, typically available at your local electronics
store, to measure the sound in areas where the alarm is expected to be heard during normal
noise environment. Results from this test may prove it beneficial to purchase additional exit
stopper units. When purchasing a remote unit (STI-6403) you will need to periodically test the
connections to make sure audibles function at a sound level to alert staff. Maximum of three
STI-6403 may be used in parallel.
All specifications and information shown are current as of publication and subject to change
without notice.
Warranty Information
· Three year guarantee against breakage of polycarbonate in normal use (one year on electro
mechanical and electronic components).
· Electronic warranty form at www.sti-usa.com/wc14

Alarm Feature Description
· Volume Switch JP2 - Sets alarm volume to high 105 dB or low 95 dB.
· Duration Switch JP3 and JP4 - Amount of time alarm sounds after trip. Arming resets at
end of duration if door is closed. Alarm will not reset if in continuous mode; alarm sounds
until battery is drained. Annunciator Mode is a series of 10 short beeps or until door is
closed.
· Trip Delay Switch JP5 - If you wish to ENTER an alarmed door without sounding the horn
immediately, the trip delay will allow 15 seconds for you to enter and de-activate the alarm
with the key switch before the alarm will sound.
· Arming Switch JP7 - This mode is useful when an AUTHORIZED EXIT is required through
alarmed door. In “ON” position immediate arming will set the alarm ready to function as
soon as door is opened. In “OFF” position delay arming will allow 15 seconds for you to exit
through the door without sending alarm signal.
Installation Instructions
1. Make sure key switch is in the OFF
position.
2. Remove tamper screw on side of unit
and remove housing cover. Save this
tool for future servicing and battery
change (Fig. 2).
3. Set switches, on circuit board, to
desired alarm settings (Fig. 1).
4. Test settings by connecting battery
or external power source. If using
external power source a Class II UL
Listed transformer is required. If power
is present at terminal block (Fig. 1) 9V battery
is in no-load on standby power consumption.
5. Mount main unit on or next to door using hardware provided. Reed switch mounting
locations can be moved to one of the four positions shown in Fig. 2. If mounted next to
door, route reed switch wire through knockout in bottom of housing as shown in Fig. 3.
6. Mount magnet on door frame (or door
if unit is mounted next to door) using
screws provided. When mounting on
metal doors or door frames, use plastic
spacers provided. Reed switch and
magnet must be within 3/4” when door
is closed (3/8” on metal door and frame).
Please refer to figures 4, 5 and 6 on page
6 for other mounting options.
7. If installing STI-6402, STI-6403, or
STI-6404 continue to page 7 for more
instructions (Fig. 7 and 8). STI-6402
mounting option is shown on page 6.
8. Replace cover by sliding flanges on
inside of cover into slots on base. Then
rotate the cover over unit and snap close.
Replace tamper screw.
Note: STI recommends setting up unit and testing settings prior to mounting.

STI-6402 Double Door Install Notes
1. Determine length needed for reed switch
wires. STI provides 1 reed switch with 6 ft.
wires. Cut to desired length.
2. Connect first reed switch in RS1 and
second in RS2 (Fig. 7). (Refer to Fig. 1 for
additional details on page 4.)
3. If not using extra reed switch, add jumper
across two terminals of RS2 on terminal
block.
*Note: Alarm will sound when either door is
opened.

2. Connect two conductor wire (14-24 AWG)
from main unit terminal block pins COM
and NO to remote horn unit terminal block.
(wire not provided). Units can be set up to
300 ft. apart. Not polarity sensitive (refer to
Fig. 1 and Fig. 7 for details).
3. Connect internal battery.
4. Mount similar to main unit with #8 x 1 in.
screws and anchors if necessary.
5. Replace cover and screws.
6. Turn key switch to ON position.
*Note: The ON/OFF key position is opposite
from 6400 main unit. Remote horn sounds
when main unit alarm is activated.
STI-6404 Double Door with Remote Horn Install Notes
The STI-6404 is a combination unit for double doors with a remote horn. Reference the installation
instructions for the main unit, the STI-6402 and the STI-6403 for complete installation.
STI-6405 Exit Stopper with Momentary Reset
The STI-6405 uses a momentary switch. After initial
installation, unit is always on and you do not have to
remember to turn it on when you leave a protected area.
This model also eliminates having to remember to re-arm it
because it is never off.
When the alarm is triggered, to silence the alarm, insert the
key and turn completely to the “RESET” position and hold
for 2 seconds, then release. The switch will spring back to
its original position and push the key out. To turn the unit
off, supply power must be removed.
