DualCom GPRS
Installation Manual
Description
DualCom GPRS is an advanced auto-dialling Digital Communication Device for
secure alarm reporting. It is supplied as a ‘dual path’ Alarm Transmission Sys-
tem (ATS) that when fully installed will meet EN50136 standard for ATS 4 & 5
that is suitable for EN50131 Security Grade 1, 2, 3 and 4 installations. In
addition, it is suitable for use in systems installed to conform to PD 6662:2010
at Grades 1-4 and for EN50136 environmental classifications 1 and 2.
DualCom GPRS is a low power device that can operate from any voltage be-
tween 9 and 30 volts DC. Quiescent current is 30mA or less.
DualCom GPRS can transmit alarm signals to an Alarm Receiving Centre (ARC)
via the radio GPRS path, the radio GSM path, the customer’s wired LAN net-
work (IP) in connection with the Internet, and the PSTN (Public Switched Tel-
ephone Network).
DualCom GPRS is supplied with a SIM Card and programmed NVM and is
ready for immediate operation.
When DualCom GPRS is triggered by the alarm system it sends messages to
the ARC over any one of its communication paths. Manually triggered test calls
are delivered using all paths to test the system fully.
DualCom GPRS monitors its radio, LAN and PSTN communication paths con-
tinuously. A fault on one path is reported to the ARC using any one of the other
functioning paths. In addition, the Gemini network continuously monitors the
polling calls from the DualCom to detect and report total path or equipment
failure.
DualCom GPRS includes extensive diagnostic, testing and setup functions
that use multiple LED displays that are controlled by push buttons.
DualCom GPRS is housed in a plastic case which protects the electronics and
meets PSTN safety requirements.
DualCom GPRS is available for use as a stand-alone unit with screw-terminal
inputs and with a Plug-on Adapter for use with Control Panels having the corre-
sponding plug-on connection.
Grade 2 and 3 tamper protected steel boxed power supplies are also available.
