(Additional smoke detectors may be added as necessary)<br />
Figure A. (Smoke Detector)<br />
Demonstrates how multiple units may be connected in parallel to perform independent non-blocking activation of alarms or warnings.<br />
If either smoke detector is activated it will activate a local 10 second alarm. It will also initiate a continuous alarm and indication in the<br />
cockpit that is controlled by VIVISUN Electronic Latching switches. The cabin alarm may be cancelled by pressing the associated cabin<br />
mute button. The Cockpit alarm is canceled by pressing the SMOKE ALARM MUTE switch or SMOKE ALARM reset switch. If a new smoke<br />
detection signal occurs the alarms will be reactivated. This example uses both channels of the VIVISUN <strong>Pulse</strong> / <strong>Timer</strong>: one channel is<br />
configured for a 10 second pulse to activate the local alarm and the other a 0.25 second pulse to activate the alarm in the cockpit.

Figure B. (Speaker Inhibit)<br />
Pressing the RAAS SPEAKER<br />
switch will cause the RAAS<br />
speakers to toggle between<br />
the INHIBITED (OFF) and<br />
ACTIVE (ON). Any transition<br />
of weight on wheels will<br />
cancel the RAAS inhibit<br />
causing the RAAS speakers<br />
to become ACTIVE (ON).<br />

Figure D. (Motor Control)<br />
Demonstrates an automatic motor control using the VIVISUN<br />
<strong>Pulse</strong> / <strong>Timer</strong>. Pressing the STOWED switch will activate the<br />
Stow relay for a maximum of 10 second causing the motor to<br />
move to the stowed direction. When the Stowed limit switch<br />
is reached the VIVISUN <strong>Pulse</strong> / <strong>Timer</strong> will be automatically<br />
reset stopping the motor. Pressing the DEPLOYED switch will<br />
activate the Deployed relay for a maximum of 10 second causing<br />
the motor to move to the deployed direction. When the<br />
Deployed limit switch is reached the VIVISUN <strong>Pulse</strong> / <strong>Timer</strong> will<br />
be automatically reset stopping the motor. Note: if the motor<br />
is currently in transit pressing the other switch will reverse the<br />
direction of movement.<br />
