This equipment 3G3070 is fixed and shall be installed by Service Persons only (Service Person is
defined as a person having the appropriate technical training and experience necessary to be
aware of hazards to which that person may be exposed in performing a task, and of measures
available to minimize the risks to that person or other persons). It shall be installed and used
within an environment that provides the pollution degree max 2, over voltages category II, in
non-hazardous, indoor locations only. This manual shall be used with the Installation Manual of
the relevant alarm control panel. All instructions specified within that manual must be observed.
Description
This 3G3070 manages transmissions to a central station and can simulate the landline in the event of
trouble (e.g., landline down) or even substitute the landline completely in areas where the 3G or 2G
wireless service is provided and a landline is not available.
The 3G3070 has the capability of communicating alarm signals via the 3G or 2G data network. This
capability ensures a fast, reliable path to central stations equipped with a Sur-Gard System I / II / III / IV /
5 receiver. By connecting a 3G3070 to a control panel's standard PSTN interface, telephone-based
Contact ID signals are decoded and seamlessly routed through the 3G or 2G network to any of the
compatible receiver options.
The performance of the 3G3070 depends greatly on wireless network coverage. Therefore, it should not
be mounted without first performing placement tests to determine the best location for reception
(minimum of one green LED ON). Optional antenna kits – GS15/25/50-ANT (15ft/4.6m, 25ft/7.6m or
50ft/15.2m) – are available.
The 3G3070 shall be powered from any compatible listed control unit or compatible listed power supply that
complies with the ratings specified on page 1. The power supply shall be listed for burglary applications and
provide a minimum of 4 hours standby power capabilities. An example of a suitable listed compatible control
unit is the DSC Model PC1864 with an AUX output rated 11.1 - 12.6VDC. An example of a suitable Listed
power supply is DSC Model PC5204 with an AUX output rated 11.6 - 12.6VDC.
ATTENTION:
The 3G3070 is equipped with a current limiter that limits current demand on the
12V
DC
power input to 120mA. The current limiter is enabled by default (see Part #8 in 'Identifica-
tion of Parts’ on page 3) with JP3 in the OFF position. The current limiter can be disabled
(bypassed) with JP3 in the ON position. When the 3G3070 12V
DC
power input is supplied by the
Alarm Panel Aux+ output, DSC recommends that the current limiter be active to limit the demand
from the panel. If the alarm panel is intended to supply all of the current demand, you must
ensure that the panel can supply 500mA and that the current limiter is disabled. When the 3G3070
is transmitting, the current demand exceeds 120mA (500mA). With the current limiter in place,
the additional current demand is supplied by the 3G3070 battery.
NOTE:
With the current limiter active, there is a risk of discharging the 3G3070 battery when
transmission frequency is high. The back up battery must always be connected to the device when
the current limiter is enabled.
If power to the 3G3070 is supplied by an external power supply (recommended 13.8 V
DC
, 0.7A), the
current limiter must be disabled to allow the full current demand to be supplied. In this configuration
the 3G3070 battery is not required.
