D. Locating and Installing the 2550
The 2550 is housed in a plastic enclosure and requires an additional 16.5 VAC –
40VA transformer (Recommended Transformers: Ademco 1361, MG Electronics
Model MGT1640 or equivalent) and backup 1.4 AH battery (Recommended
Battery: Powersonic PS-1212 or equivalent). The recommended battery
measures 3.8 inches long by 2.3 inches high by 1.7 inches wide. A battery wider
than 1.7 inches will not allow for proper closure of the Uplink 2550 case.
After carefully considering all issues outlined in Section B (General
Considerations), proceed as follows:
1. Separate the top and bottom of the enclosure by depressing the tab on the
bottom of the unit and tilting the bottom of the plastic top outward and up.
2. Connect the supplied antenna with the 2550. The Antenna supplied may differ
from the ones depicted in the figures in this manual.
3. Go to the red, 4-position Dipswitch as shown in Figure 1 and set the dipswitch
as appropriate for this installation. (See Section 7B.)
4. Place Dipswitch #4 (S4) in the ON position. The LEDs are now operating in
RSSI Mode. Locate a good mounting position based on a good Received
Signal Strength Indication (RSSI).
It is recommended that the
installation location demonstrate an RSSI of at least -60 dBm (3
solid green LEDs).
The minimum acceptable RSSI is -80 dBm (1 solid
green LED). If the minimum acceptable RSSI cannot be achieved with the
supplied antenna at the installation location, contact customer service.
