4.2 PCB
The TG-7FS LTE unit has I/O connections for communication and power, as well as
LEDs to display device status.
4.2.1 I/O Connections
• Antenna port: TNC female connection, 50 ohms
• RJ connections: Two RJ-45 connectors. Gray jack from communication from
the panel. Black jack for pass through to incoming Telco (not applicable to
sole path)
• Pin connectors and terminal blocks: There are four sets of pins, with three
available terminal blocks.
o DC-GND pins: 6.2V-16VDC in. To be used if receiving power from an
FACP with an auxiliary output within that range.
o STC and Trip In pins: There are two pairs of STC pins. STC 1 acts as a
Normally Open relay that will trip on a programmed Telguard failure,
whereas STC2 will trip as a Normally Closed relay. There is also a pair of
Trip Input connections labeled as Trip and Gnd, which can be optionally
used to monitor a dry contact device, with the capability of sending an
event to Central Station or provide customer notification on that trip
closure/restoral.
o Battery pins: There is a set three pins labeled as BATT, with only the
outer pins functional and labeled as – and +. This is an alternate
connection for the battery, with the same functional specifications as
the battery connector.
o AC pins: There is a set of two pins for the AC Adapter to connect to.
Polarity is not labeled because it is AC voltage
• Battery Connector: There is a VHR-2N connector that is keyed to fit with the
provided battery harness. Polarity is not labeled as the battery harness can
only fit in a specific way.
