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 initializes. The red and yellow
LEDs will continue to flash until the communicator has successfully 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 trouble and the green LEDs are not valid for communicator placement test).
Correct trouble indicated by flashes on yellow LED before continuing. (See Table 7 for troubleshooting assistance).
7.
Perform the communicator placement test below.
8.
Mount the panel in final location indicated by placement test.
Cellular Communicator Models Only
To confirm that the cellular antenna location is suitable for radio operation, perform the placement test as follows:
NOTE: It might be necessary to relocate the panel or install an optional extension antenna during this procedure, if the
radio signal strength is too low.
1.
Confirm that the yellow LED on the communicator is not flashing. A flashing yellow LED indicates trouble on the com-
municator. See Table 7 to troubleshoot and correct the cause of this trouble before continuing to the next step.
2.
Confirm 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
(furthest from the yellow LED) is
receiver strength on LEDs, refer to the table
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 followed by up to five bars of signal strength. This display will auto-
matically update every three seconds. For the relationship between signal strength bars, CSQ level, and signal level in
dBm, refer to "Radio Signal Strength".
SIM card active and current signal strength
SIM card inactive and current signal strength
Radio not registered
NOTE: If the required signal strength is too low with the panel in its current location, the panel must be relocated or an
external antenna is required.
If required, the following cellular extension antenna kits are available to the installer:
GS-15ANTQ - 4.57m (15') internal antenna extension kit (suitable for interior mounting).
l
GS-25ANTQ - 7.62m (25') external antenna extension kit (suitable for interior/exterior mounting).
