5.4.2.2 Check Proper Operation of Telguard Supervisory Output

Check for proper operation of each programmed supervisory output by causing it to trip the C/C and be

sure the proper LED illuminates and that the proper trouble code is reported to the central station. Skip

the testing of any supervisory functions that have not been enabled. Note that the yellow MODE LED #3

starts to flash when the C/C goes off-hook to report the alarm signal over cellular.

• Low Battery Condition (LBC)

: Disconnect the battery and during the next 60 seconds check to see

that the STC LED #2 flashes 2 times indicating that the battery is missing. Check to see that the C/C

transmits the STC trouble code (over cellular) to the central station. Reconnect the battery and

check during the next 60 seconds to see that the STC LED #2 goes off, indicating the missing battery

condition has been restored.

• Line Fault Condition (LFC):

Disconnect J/J cable at RJ-11. Check to see that the STC LED #2

flashes 3 times in 30/60 seconds and the C/C transmits the STC trouble code (over cellular) to the

central station indicating the incoming telco line is disconnected. Reconnect J/J cable and check to

see that the STC LED #2 goes off in 30/60-seconds indicating telco line restoral.

• No Service Condition (NSC)

: Disconnect the antenna from the Telguard. Check to see that the

STC LED #2 flashes 4 times in 30/60 seconds and the C/C transmits the STC trouble code over the

telco line indicating loss of RF signal strength. Reconnect the antenna and check to see that the

STC LED #2 goes off in 30/60-seconds indicating RF signal strength restoral.

Note: The Received Signal Strength (RSSI) must be less than -114 dBm in order to cause a NSC

condition. If the Telguard is located in a high signal strength area (close to a cellular tower),

it is possible for the signal strength to be greater than -114 dBm even with the antenna

disconnected.

• AC Fail Condition (ACFC)

: Disconnect the 12VAC, 10VA transformer and check to see that the AC

POWER LED #6 goes out and the STC LED #2 flashes once indicating that AC power is missing.

Reconnect the AC transformer and check to see that the AC POWER LED goes on and the STC

LED goes off indicating that AC power has been restored. No transmissions will be sent to the

central station. The AC power must be off, continuously, for 2-hours before the STC relay causes

the C/C to send a trouble code. If the AC power is restored for 60 seconds or more, then the 2-hour

timer restarts.

5.5 STEP 5: COMPLETE THE TELGUARD INSTALLATION

Last step is to handle loose ends.

5.5.1 Check Settings

Check the jumper setting of J10 (LED mode, “OPEN” = normal, “SHORTED” = RSSI mode).

5.5.2 Permanently Mount and Properly Ground the Telguard Chassis

Attach earth ground to the green grounding screw located on lower right-hand corner of printed circuit

board assembly and permanently mount the Telguard enclosure.

Using the enclosure as a template, mark the top mounting holes on the mounting surface

Pre-start the mounting screws (not supplied) for these two holes. Slide the enclosure onto these screws

so that the screws move up into the thinner section of the holes. Tighten the screws.

Screw in the remaining two screws in the bottom set of mounting holes.

Knock out the desired wire entrance on the enclosure.
