2. Replace ALERT1 receiver with 5052RD-K ALERT2 receiver/decoder Upgrade base station software to receive ALERT2 data Make ALERT2 source address and TDMA plan Upgrade ALERT1 repeaters to receive and transmit ALERT2 Upgrade remote stations to transmit ALERT2

3. Replace ALERT1 receiver with 5052RD-K ALERT2 receiver/decoder Add ALERT1 receiver/decoder option to collect legacy ALERT1 date during upgrade transition Rack mount installation recommended Desktop installation possible Use AC power adapter Connect to battery backup power system Stand alone battery with charge no longer used Antenna splitter uses same receiver antenna for ALERT1 and ALERT2

9. ALERT2 Receiver Decoder ALERT1 Receiver ALERT1 Transmitter ALERT1 ALERT1 and ALERT2 Antenna Splitter ALERT1 Receiver Decoder Polyphaser Battery Backup Battery with charger AC Power

10. Install powered preamp after polyphaser Increases received signal to offset splitter and filter insertion losses Install antenna splitter after preamp Antenna splitters have small insertion loss Install cavity or crystal filters after splitter Separate filters required for ALERT1 and ALERT2 receiver frequencies Crystal filters have the best performance as filters Very compact size and inline installation 7dB insertion loss requires preamp for signal boost 8 week delivery so order in advance

17. Check type and gender of antenna cable connectors Polyphasers, splitters, crystal filters connect to N male cable connector ALERT2 receiver connects to a BNC male connector Connecting cable from polyphaser to splitter Check length of cable required Remove existing polyphaser from ALERT1 receiver? Preamp increase in signal level for ALERT1 may require a higher squelch level in radio receiver -104 dB instead of -113 dB

18. Select a source address range available in region Possible numbers are 1 to 65534 Orange County CA range is 23000 to 23999 Do not limit yourself to old ALERT1 ID range Coordinate with other ALERT2 users in region Record source addresses with regional or national web page sites

19. Pick frame size for transmitters 120 transmitters with 500 millisecond slot in 1 minute frame Pick frame size for repeaters 5 second slots Frame size = # repeaters * 5 seconds Assign station slots Transmitter slot should be before repeater slot Leave room for expansion before repeater slot Use first slots for stations with few sensors Use later slots for stations that require time for data collection, for example wireless links.
