AIS LifeGuard Quick Start Guide
QUICK START AIS LIFE GUARD V1.00
4. Operation
When powered up, the AIS LIFEGUARD will emit a short beep and the Green and Red LEDs will quickly flash
for about 1 second and then the Green LED will stay on. This is the normal state of the AIS LIFEGUARD and
indicates that it is working correctly.
Every time that a valid !AIVDM message is received from the AIS system, the Green LED will briefly flash which
indicates that correct NMEA 0183 data communication is taking place.
The AIS LIFEGUARD checks all MSG1 and MSG14 AIS Sentences to see if an AIS SART/MOB/EPIRB has
been activated or tested. If it detects one of these conditions, then AIS LIFEGUARD alarms in the following way;
ALARM TYPE
RED LED
INT BUZZER
EXT BUZZER
MUTE ALARM
REAL
CONTINUOUS
CONTINUOUS
CONTINUOUS
MANUAL
TEST
FLASH x5
BEEP x5
SILENT
AUTOMATIC
A Real Alarm will cause all audible and visual alarm indications to occur and can only be “Muted” by someone
pressing the Mute/Reset button. A short press of the Mute/Reset button will cause the Internal and External
buzzers to silence but the Red Alarm LED will stay illuminated to show that an alarm condition has occurred and
that the MMSI number of the SART that caused the alarm is stored in memory and will not cause another alarm.
The AIS LIFEGUARD will alarm again if it detects another alarm message from a SART with a different MMSI
number. The AIS LIFEGUARD can store up to 20 different MMSI numbers of SARTs that have activated the
Alarm. Each time a SART makes the AIS LIFEGUARD alarm, the Mute/Reset button must be pushed to silence
that particular alarm.
After an emergency situation has finished and one or more alarms have occurred and been silenced by pressing
the Mute/Reset switch, the AIS LIFEGUARD should be RESET to make it forget all of the previous MMSI
numbers of SARTs that have triggered an alarm. To RESET the AIS LIFEGUARD, press and hold the
Mute/Reset switch for 4 seconds until the Internal Buzzer beeps once and the RED Alarm LED goes out.
Most AIS SARTs have a test mode and the AIS LIFEGUARD allows you to easily test the AIS SARTs before
commencing a voyage. When the AIS LIFEGUARD detects a SART in test mode, it Beeps the Internal Buzzer
and flashes the RED Alarm LED five times. If you have multiple AIS SARTs to test, it is recommended that you
test them one at a time. Activate the AIS SART test mode, and at the end of the test, the AIS LIFEGUARD will
beep and flash to indicate the test has worked, before automatically returning to normal operation.
NOTE
– the AIS LIFEGUARD has a Self-Test mode which is entered if you press and hold the Mute/Reset
button whilst the AIS LIFEGUARD powers up. In Self-Test mode the two LEDs and the Internal and External
buzzers are turned ON, which is useful for testing that everything is working correctly. To exit Self-Test Mode
simply release the Mute/Reset switch.
