Communicator Placement Test - DSC TL2803GR Installation Manual

5. Install the RS-422 connections (R models only). If using the communicator with a 3rd party
device, wire the connections as per the table below:
NOTE: The GND connection is optional. DSC recommends connecting GND wire at both ends.
6. Perform the following steps for initial power on of the panel with communicator installed:
a. Reconnect the AC power, telephone line, and battery + connector to the panel.
(The communicator and panel will power up together).
b. Observe that the communicator's red and yellow LEDs are flashing together while it initial-
izes. The red and yellow LEDs will continue to flash until the communicator has success-
fully communicated to all programmed receivers.
NOTE: During radio reset, the two green LEDs will flash alternately.
NOTE: Initialization may take several minutes to complete. red and yellow LEDs will flash
together during initialization. Do not continue to next step until the red and yellow LEDs
have stopped flashing. (If only the yellow LED is flashing, there is a communicator trou-
ble and the green LEDs are not valid for communicator placement test). Correct trouble
indicated by flashes on yellow LED before continuing. (See Table 8 for troubleshooting
assistance).
7. Perform the communicator placement test below.
8. Mount the panel in final location indicated by placement test.
3G2080(R) and TL2803G(R) only
To confirm that the cellular antenna location is suitable for radio operation, perform the placement
test as follows:
NOTE: You may need to relocate the panel or install an optional extension antenna during this
procedure, if radio signal strength is too low.
1. Confirm that the yellow LED on the communicator is not flashing. A flashing yellow LED indi-
cates trouble on the communicator. See Table 8 to troubleshoot and correct the cause of this trou-
ble before continuing to the next step.
2. Observe that the strength of the radio signal on the yellow LED and the 2 green LEDs on the
communicator meet or exceed the minimum signal level requirement. Minimum signal level:
The yellow LED is OFF and the green LED 1
not flashing) for the panel location to be acceptable. See table for "Radio Signal Strength" on
page 16 for interpretation of receiver signal strength on LEDs.
Cellular Signal Strength Display - LCD Keypad Only
The cellular network signal strength can be checked on the keypad LCD screen by entering
installer programming section [850]. The LCD will indicate the SIM card activation status fol-
lowed by up to five bars of signal strength. This display will automatically update every three sec-
onds. Refer to "Radio Signal Strength" on page 16 for the relationship between signal strength
bars, CSQ level, and signal level in dBm.
