transmission. If the alarm format is changed for whatever reason, the Telguard will sense the new
format and accept the alarm signal.
In order for the alarm panel to be compatible with the Telguard, the alarm panel must be
programmed to transmit alarm messages to the central station using one of the following non-
extended formats:
Pulse Formats:
o
3+1 pulse; 10pps, Double Round, 1400Hz ack
o
3+1 pulse; 20pps, Double Round, 2300Hz ack

OMMUNICATION
P
ATH
The Telguard TG-4 continuously supervises both the Telco and cellular communication paths. If
either communication path becomes inoperative, the Telguard generates a relay trip output that can
be connected to a zone input of the host alarm panel and/or used to control remote annunciation
devices.

ECURITY
The Telguard TG-4 meets the requirements for Standard Line Security (equivalent to previously
known AA Grade security) when used with a UL Listed compatible alarm panel and when monitored
using the 200-second Supervision cellular service plan. The 200-second supervision is required to
meet Standard Line Security. Once the TG-4 model is provisioned with the 200-second supervision,
the TCC constantly monitors the cellular path and sends a specific message to the central station if
the path is broken. After the initial account activation is done, the installer must verify the Standard
Line Security by turning off the device for 200 seconds and making sure an alarm with the specific
code is delivered to the central station.
WARNING: Standard Line Security has only been evaluated between the TG-4 and the
TCC. It is the responsibility of the installer to verify Standard Line Security from the Listed
control unit to the Listed receiver through the TG-4 as marked on the alarm panel and as
indicated in the control unit manufacturer's installation instructions.

ONDITION
(LFC)
The Telguard monitors voltage on the incoming Telco line. If an inoperative Telco line is identified,
(voltage below –20vdc, on hook) a Telco line fault condition (LFC) is declared. The System Trouble
Condition LED (STC LED) will flash 3 times and the STC relay will trip after a programmable delay of
30 or 60 seconds. Upon Telco restoral, the relay and STC LED are returned to normal.
