EPORT
The Telguard automatic self-test signal is originated by the Communication Center on a daily, weekly, or
monthly schedule (note: UL Listed installations require a daily self-test). When the time for an automatic
self-test occurs, the Communication Center transmits a radio signal to the Telguard and the Telguard responds
with a self-test radio signal that is received by the Communication Center and processed on to the central
station, just as normal alarm signals are processed. The central station receives the automatic self-test report
in the same format that the C/C normally uses for communication over the telco line. The central station
provides the Telguard self-test code along with the time and frequency of transmission when the Telguard is
initially activated. However, an automatic self-test report can be initiated later, after the Telguard is
installed, as well as modifying the time or frequency of reporting.
The Communication Center captures all current and historical data pertaining to the operation of the Telguard
when it processes the automatic self-test signal on to the central station. This data contains current
operational status (C.O.S.) of the Telguard such as "All OK", "AC fail condition", "low/missing battery
condition", "line fault condition", or any combination of these as well as the current signal strength and mode
of operation. In addition, the data also contains historical data for supervisory events that occurred since the
last self-test signal was transmitted. This data includes the number of occurrences of AC fail conditions, low
battery conditions, line fault conditions, communications failure conditions and no cellular service
conditions. This self-test data is available for review at any time by authorized personnel such as installers,
dealers, central station operators, or technical service personnel. Methods used to review this data include
Telular's Interactive Voice Response System (IVR), Telular's computer access Communication Center
Intranet System, or simply calling Telular Customer Service who can review the data using the "Back Office"
program.
2.5.1 Telguard Remote Query Capability
Although Telguard has the capability for a daily, weekly, or monthly automatic self-test, a separate
feature is provided for determining the current operational status of every Telguard. This feature is
called Remote Query and is used to provide real-time operational status for Telguard on-demand. It
is useful in resolving STC events that are reported by the C/C to the central station. Authorized
personnel can initiate the Remote Query at any time by accessing the IVR, Intranet, or calling
Customer Service. The Remote Query causes Telguard to upload current operational status data and
historical data, just as the automatic self-test described above, except that the query signal is
controlled by the one who initiates it. The query signal is held in the Telguard database at the
Communication Center for review and is not forwarded on to the central station.

ONNECTIONS
The conveniently located terminal strip provides wiring connections for the Telguard supervisory trip output
(STC-pins 1&2, N.O.), battery leads for connecting to a 12 volt 7.0Ah, or 14.0AH rechargeable battery
(BAT-pin 3 neg., pin 4 pos.), and AC power (16.5VAC 20VA, pins 6&7). The removable terminal strip can
accommodate solid or stranded wire sizes from 14 gauge to 30 gauge.
2.6.1 Programmable Supervisory Trip Output (STC) Relay
The Telguard has one supervisory relay trip output (STC), a single pole single throw (SPST, form
C) with contacts rated at 1.0A 30VDC, and is energized normally open (N.O.) in a powered up state
when no system troubles exist. It enables a supervisory trouble code (zone shorted) to be
transmitted to the central station when connected to a C/C’s 24-hour instant input zone. The STC
relay is programmable, using a standard touch-tone telephone or buttset, to meet virtually any
installation requirement.
The following supervisory features or combination of features are programmable to trip the STC
relay in order to meet a variety of installation requirements:
•
Always Off.
•
Trips on
AC fail condition
(ACFC)
•
Trips on
low or missing battery condition
(LBC).
•
Trips on
line fault condition
(LFC).
•
Trips on
no service condition
(NSC).
•
Trips on
radio communication failure condition
(RFC).
