GSM SIM card (IRIS Touch 200 & 240)
6.4.
DO NOT FIT the SIM card until after you have performed the GPRS Network Scan detailed in the
Section 6.8
“Configuration”
you will be prompted when to insert the SIM card.
Dial capture
6.5.
Dial capture enabled systems
: Connect the dial port screw terminals with the alarm panel dialler telecoms
line connections.
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.
PIN Inputs
6.6.
The IRIS Touch dialler has 4 pin inputs
that can be used to generate alarm messages, if you require more
than 4 pin inputs then you can fit the IRIS Touch
expansion board (ordered separately). These can be:
Text messages via SMS
(GSM
).
SIA, Contact ID and 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 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
6.7.
To confirm power is applied, look for the indicator SYS LED is flashing yellow
on the IRIS Touch dialler
board.
