remote unit (STI-6403 or STI-6404) you will need to periodically test the connections to make
sure audibles function at a sound level to alert staff. Maximum of three remote alarms may be
used in parallel.

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.
