ALP Fingerprinting
[Download not found]
ABSTRACT:
As we transition to G4, ALP (Advanced Locating Protocol) will become an integral part of our increased locating capability. Fingerprinting or mapping a facility properly is essential to the accuracy and reliability of this new capability. However, if not done in the correct order, it can cause lots of headaches and extra work.
TECH SUPPORT SUMMARY:
ALP Now uses RSSI (Received Signal Strength Indicator) to record and measure the location of a resident in your facility. Fingerprinting is the recording aspect of this process in which the installer will build a database of average signal strengths for locators in a specific area. The Fingerprinting table will create a database that is then used to match the values of signal strength when a regular device triggers an alarm.
Step 1: Learn pendant in as device function “Fingerprint”.
Step 2: Select New Fingerprint Option in System Settings to access Fingerprinting Table.
Step 2: Select New Fingerprint Option in System Settings to access Fingerprinting Table.
Step 3: Fingerprinting – This must be done in this specific order or you will not have accurate data.
A) Select Add New Location
B) Enter Floor Number (Must be Numerical) and Description. The more descriptive the better because the information in this field is how location will now be reported to end users. Then Press Save Location.
C) Press device every 10 seconds with a recommended minimum of 5 presses per location. Outer limits and a central location is best. You may need to hit refresh a few times before the correct quantity shows up as the database processes our calls
D) VERY IMPORTANT: This location that you saved last will remain the active fingerprinting location until you save a new one. You MUST save before the location can be fingerprinted or else you are finger printing the previous location still and filling your database with inaccurate signal strength values. Do not worry that your saved location does not populate automatically. It does not populate until it has data. By hitting Refresh it will populate with an update on the quantity of presses. There is a lag on the press quantity as the system process new data into the database, but if you do not wait the full 10 seconds it may not register your press properly. You will not be able to go back to a location once you have finished fingerprinting it. If you made a mistake, you will have to delete entry and re-fingerprint that section.
Step 4: Verify by select a “Normal Call” Pendant that has been programmed to confirm location
SOLUTION:
The more descriptive, the better! Remember, the description you manually enter is now the data that will be presented to caregivers. Make sure they understand your descriptions before leaving a facility. First Floor West means nothing if they consider that hall the 100 Hall. Outside areas like parking lots or near elevators that has increased natural interference require more presses to make the average value more accurate. If you fingerprint your facility using the proper steps you will have a drastically improved ability to locate residents. If you do it wrong, you could have drastically decreased your ability.
