Notes:

tone instead of the pre-recorded message.
2. The strobe circuit is a latching output. Once the strobe circuit is energized, it will stay energized until
the “RESET” switch is activated. Activating the “RESET” switch has no effect while an evacuation
signal is initiated.
3. The strobe circuit does not latch on when a digital voice message is being played from the MDX-2.
When the message ends the strobe circuit will revert back to standby mode.
