nominal 20 minutes if old GPS position data is stored in the memory of the RapidFix™. If there is no old GPS position
data present, the beacon will acquire current data within a minute of being connected to a GPS with a valid position fix.
You can force the RapidFix™ to update its position at any time by connecting to a GPS with a valid position fix and
initiating the Self-Test (see 5.10). If valid GPS position data is not available, the beacon will not clear the previously
stored GPS position data. In this case, call ACR Customer Service at +1 (954) 491-3933 for instructions on how to
reset the RapidFix™ with the beacon's default message.
Testing the GPS Interface
Connect the optical interface plug to the RapidFix™ bezel and allow sufficient time for the GPS receiver to acquire
valid GPS position data (usually less than 1 minute; but it can take up to 20 minutes). Lift the thumb switch to the
vertical (Self-Test) position and release. Your RapidFix™ will confirm that it has acquired valid GPS data by emitting a
beep along with a flash of the red and green LEDs. This will occur approximately 2.5 seconds after the Self-Test.
Updating GPS Position Data
When the beacon is properly connected to a functioning and compatible GPS receiver, GPS position data is
automatically updated about every 20 minutes, while valid GPS position data is present UNLESS the beacon is
activated. The operator can force the acquisition of new GPS position data, by executing a Self-Test with the beacon
connected to a GPS with a valid position fix. This bypasses the normal, programmed, waiting time of 20 minutes for the
automatic update of GPS position data. Once the RapidFix™ has completed the Self-Test sequence by emitting the
beep and flash of red and green LEDs, as described in 5.10, the RapidFix™ will request and acquire new position data
from the GPS. This can take a nominal 15 seconds or up to one minute.
NOTE: While the beacon is not activated, GPS position data will be received and continuously stored by the
RapidFix™. No GPS position data updates will occur while the beacon is activated.
A new RapidFix™ is programmed with the GPS position data set to "default." This default GPS position data indicates,
upon activation, to the satellite system that the beacon has no valid GPS position stored in memory. Once a
functioning and compatible GPS receiver is properly connected to the beacon, this "default" data will be replaced by
valid GPS position data, as described in the previous sections.
SECTION 6 – CARE AND MAINTENANCE
6.1
Routine Maintenance
At least every ninety days, the Category I mounting bracket and beacon should be inspected for deterioration and/or
residue buildup that may affect the function of the beacon or automatic release. Part of the visual check includes
checking the antenna for tightness. Clean the beacon and the mounting bracket to remove residue buildups. It is
recommended that the beacon and mounting bracket be wiped with a damp cloth.
Carefully inspect the beacon case for any visible cracks. Cracks may admit moisture, which could falsely activate the
beacon or otherwise cause a malfunction. Any cracking observed should be immediately referred to ACR for evaluation
by calling 1-800-432-0227 ext. 2155 in the US, or +1-954-981-3333 ext 2155 elsewhere.
6.2
Battery Replacement
For beacons with model number RLB-33
Battery replacement is due 5 years from date after the beacon placed into service, or by date on beacon whichever is
first. During each inspection, check the time remaining until battery replacement is required. The battery must also be
replaced if the beacon has been activated for any use other than the Self-Test.
For model RLB-32 beacons with "NH" in the model number
RLB-32 beacons with "NH" as part of the model number contain non- hazardous lithium batteries.
It is the beacon owner's responsibility to record the expiration dates for both the beacon battery and the HydroFix™
hydrostatic release unit. This information must appear on the product itself.
The left side of the battery housing indicates the battery expiry date. Space is provided for the beacon owner to mark
the date the beacon was placed into service. The beacon should be serviced 5 years from the installation date but no
later than the battery expiry date.
