1. Introduction
Uplink’s MODEL 2550 GSM Alarm Communicator is a UL Listed alarm
communicator designed to interface with most manufacturer’s alarm panels that
incorporate a digital telephone dialer. A key feature of the 2550 is a “
dialer
capture
” interface to the alarm panel. If the alarm panel’s TELCO connection is
compromised, or if no TELCO connection is present, the 2550 will “
intercept
”
the alarm panel’s digital dialer output when the panel has an event to report, and
communicate with the panel as if it were a central station alarm receiver. Once
the 2550 communicates with the alarm panel, it transmits the alarm information
to the central station receiver in either Contact ID (SIA-DC05) or SIA (SIA-DC03)
format.
The 2550 uses GSM technology to send event information to the central station.
It can be used as the primary or backup communications path. The 2550 is
perfect for residential and small business burglary and fire installations. (Please
refer to the UL Compliance section of this manual for detailed requirements on
compliance with various UL Standards.)
2. Key Features
A. Full Event Reporting
.
Compatible with most alarm panels using Contact
ID (SIA DC-05 Standard) or SIA FSK Level 1 (SIA DC-03 Standard) digital dialer
formats. All event information sent by the alarm panel in either format (Account
number, zone information, User IDs, etc.) will be sent to the central station by the
2500 using the GSM network.
B. Telephone Line Supervision
.
Features a built-in telephone line
monitoring circuit designed to detect voltage (in the On-Hook state) or voltage
and current (in the Off-Hook state). If sufficient voltage or current is not detected,
a relay is activated causing the unit to “intercept” (or “capture”) the alarm panel’s
digital dialer output and substitute the GSM cellular network instead of the Public
Switched Telephone Network (PSTN) as the communications path for sending
event information.
C. Panel to 2550 Cable Supervision
.
Monitors continuity of the cable
connecting the panel’s telephone dialer to the 2550. This feature is activated
through the web site
www.numerexsolutions.com
or by calling Uplink Customer
Service at 1-888-9-UPLINK (1-888-987-5465).
D. Two Zone Inputs
.
Reports programmed events to the central station.
Programmable for Normally Opened or Normally Closed.
E. Three Relay Outputs
.
Programmable to activate upon the occurrence of
one or more of the following Trouble conditions:
•
Cellular Network Loss
•
No Central Station Acknowledgement
