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 host alarm panel to be compatible with the Telguard, the 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
o
3+1 pulse; 40pps, Double Round, 2300Hz ack
o
4+2 pulse; 10pps, Double Round, 1400Hz ack

Complete Supervision of Communication Path
The Telguard TG-1 Express continuously supervises the (cellular)
communication path. If the cellular communications path becomes
inoperative, the TG-1 Express generates a relay trip output that can be
connected to a zone input of the host alarm panel and/or used to activate
remote annunciation devices.
No Service Condition (NSC)
The Telguard TG-1 Express declares a no service condition (NSC) when it is
unable to register with the cellular network.
NSC is programmable to trip the supervisory relay output (STC relay) after a
variable period of time. The STC LED will flash 4 times immediately after
losing cellular. NSC restoral occurs immediately after cellular service has
been acquired.
