STC LED #2 goes off after a period of time, indicating cellular
service has been restored.
Step 5: Connect and Test the Trip Input (optional)
In addition to the interface to the alarm panel, a single trip input may be
connected to the terminal block of the Telguard TG-1 Express. When the
input is tripped and properly configured within TelguardOnline, a custom
message can be generated and sent to the central station. This allows an
external relay, separate from the alarm panel, to be connected to the Telguard
unit in order to provide independent sensor input for other functions, such as
tamper detection.
The trip input is connected to the external relay by wiring one side of the
external relay to the TRIP IN terminal, and the other side to either the GND
terminal or to the chassis ground on the Telguard TG-1 Express circuit board.
Note that trip inputs are normally wired such that there is a 2.2kΩ resistor in
parallel with the external relay, so that a tamper condition (i.e. a cut wire) can
be detected.
When the trip input functionality is being used, closing the trip contact will
cause the Telguard unit to send a message to the Telguard Communication
Center, which in turn will cause the Telguard Communication Center to send
a message to the central station. If the Telguard unit is configured to report
restorals, the contact opening will also be reported.
UL Note: Trip input is not evaluated when connected to Burglary Zones
on the panel. For UL installations, burglary zones shall not be connected
to the Trip Input.
Step 6: Complete the Telguard Unit Installation
The last step is to permanently mount the Telguard unit.
1.
Attach earth ground to the grounding screw located on lower left-
hand corner of printed circuit board assembly and permanently
mount the Telguard enclosure.
2.
Install the mounting screws (not supplied). The “keyhole” mounting
holes on the back of the Telguard TG-1 Express are 2.5” apart,
center-to-center.
