GPRS/3G SIM Card (IRIS Connect Duo only)
DO NOT FIT SIM card until after you have performed the GPRS/3G Network Scan detailed in the
Section 7.9
“Configuration”
you will be prompted when to insert the SIM card.
Dial Capture
Dial capture enabled systems: Connect either the dial port RJ45 or the 2 dial screw terminals with the supplied RJ11
dialler cable to the alarm panel dialler telecoms line connection. If the alarm panel has screw connections, cut the
connector off the cable and strip the cable using the 2 inner wires.
Note: Polarity is not important in this instance.
Fit the supplied 18K sense resistor in parallel with the dialler output of the alarm panel, at the alarm panel end of the
cable.
Note: This resistor enables the dialler to detect cable faults and/or tampers and must be fitted at the alarm panel
end of the cable to function correctly, the monitoring centre will also need to enable the dial port monitoring from
the IRIS Secure Apps software to receive alarm notifications.
Pin Inputs
The IRIS Connect dialler has 2 Pin inputs
that can be used to generate alarm messages. These can be:
Text messages via SMS (GPRS/3G).
SIA, Contact ID or Fast Format alarm messages over IP to the monitoring centre.
Note: These pin alarm inputs can also be used when the dialler is directly connected to an alarm panel via the dial
capture, serial or RS485 connections.
Via Open/Close Contact Source
Each pin input is designed to be connected in a loop via an open/close contact
source from an alarm panel, or other device, to a reference ground pin available
on the IRIS dialler, as shown opposite.
Opening the contact (i.e. loop is open circuit) generates an alarm signal. Closing
the contact generates the equivalent restore signal.
Via Sense Resistors
It is also possible to link the contacts to the IRIS dialler via sense resistors so that
an open or short circuit tamper on the loop can be detected and the monitoring
centre alerted. In this case, the connections should be made as shown opposite.
Note: For this feature to work correctly it is essential that the resistors are
connected at the contact end of the loop and not the dialler end. The
monitoring centre must also enable the monitoring of this facility on the
dialler within the IRIS Secure Apps receiving system.
Switch On and Test
To confirm power is applied, look for the indicator SYS LED flashing red
on the IRIS Connect dialler board, top left
hand corner.
