2.7.1 LED Signal Strength Indication
The Telguard provides the installer with an easy to use LED radio signal strength indicator (RSSI) for
positioning the unit or remote antenna to obtain the strongest RF signal possible. A signal strength reading
can be obtained at any time there is power applied to the Telguard without affecting the operation of the
unit. When the “RSSI” jumper J10 is “IN”, the Telguard displays the current received signal strength
within 5 seconds. The signal strength is read from Left to right using the four sequential LEDs located on
the top right side of the printed circuit board with the Radio TX LED = 1 and the AC POWER LED = 4.
RSSI Value LED’s Lighted RF dBm
NO SVC LED 1* = on, LED 2-4 = off
≤ -114 dBm
0 LED 1 = on, LED 2-4 = off
≤ -111 dBm
1 LED 1 = on, LED 2 = slow flash
LED 3-4 = off
≥ -110 dBm
2 LED 1-2 = on, LED 3-4 = off
≥ -100 dBm
3 LED 1-2 = on, LED 3 = slow flash
LED 4 = off
≥ -90 dBm (Minimum signal
strength required)
4 LED 1-3 = on, LED 4 = off
≥ -80 dBm
5 LED 1-3 = on , LED 4 = slow flash
≥ -70 dBm
6 LED 1-4 = on
≥ -60 dBm
