c. Disconnect the Positive and Negative connections to the battery.
E. Connecting The 2550 to the Alarm Panel and Telephone Jack
IMPORTANT
: Make all connections to the 2550 in the powered down state.
Once all connections have been established, turn power on.
1.Remove AC and battery power from the 2550, then proceed as follows:
2. Dialer & Telco Connections.
a. Use the dual modular plug telephone cable provided with the 2550 to
connect it to the premises’ RJ31X jack. On the 2550’s side, one end of
the cable should be plugged into Jack JP4 (the Jack closer to the
Antenna). The other end of the cable should be plugged into the RJ31X
unit’s modular jack.
b. Connect the alarm panel’s telephone output to the 2550 with an
appropriate cable. On the 2550’s side, the cable should use an RJ45 plug
and be connected into Jack JP3 (the Jack closer to the Terminal Strip).
3. Inputs
The 2550 has two EOLR supervised inputs that report to the central station when
activated. These inputs are disabled in the default state and must be enabled via
the Dealer Web Site. The EOL resistors should be 2.2 kohms.
Connect activation devices into terminal strip JP10, terminals 7 (IN 1+) and 8 (IN
1-) for Input 1, and terminals 9 (IN 2+) and 10 (IN 2-) for Input 2 as needed. Both
inputs are Normally Open.
Note: It is recommended that Input 1 be used as a “Summary Alarm” input
from the alarm panel if the panel is capable of providing such an output. This
will provide the system with additional protection by reporting an alarm to the
central station in the unlikely event that the Telephone Line Supervision Circuit
has been circumvented by a perpetrator.
4. Outputs
The 2550 has three relay outputs that can be used to activate inputs on the alarm
panel or for other local purposes. Decide on how to use these outputs, then wire
them to terminal strip JP10 as follows:
Output #1
Terminals 1 (OUT 1+) and 2 (OUT 1-)
Output #2
Terminals 3 (OUT 2+) and 4 (OUT 2-)
Output #3
Terminals 5 (OUT 3+) and 6 (OUT 3-)
