Enable; Inverse Polarity - AddSecure IRIS-4 Technical Reference Manual

Test alarm
Where the IRIS terminal is not connected to an alarm panel that can itself
generate a regular test alarm (e.g., when inputs are used), it can be convenient
for the terminal to generate a regular test alarm. This gives the ARC a consistent
way to monitor end-to-end connectivity across many installations.
Add SIA Timestamp
This option causes the terminal to append the date and time to any SIA format messages generated
internally, including those generated from activity on the Pin Inputs. The date and time will be correct only if
the terminal is connected to an ISA 4 system at the ARC as this can send the date and time to a terminal.
Note: The timestamp cannot be enabled if the PSTN transmission path is selected, likewise the PSTN
transmission path cannot be selected if timestamp is already enabled.
6.12 Incoming IP address
This lets you limit incoming calls to the terminal serial port to up to three source
IP addresses. If all the addresses are left blank, all calls are allowed.
6.13 Pin inputs
This lets you set the alarm format for the pin inputs to SMS, SIA, Fast Format (FF) or Contact ID (CID).
Note: You can select one alarm format, see subsections below, for the pin inputs (SIA, FF or CID)
and then also setup individual pins to be SMS messaging if required.
When changing the alarm format, you will receive a warning message indicating
that all current pin inputs will be setup for this alarm format and returned to the
default settings shown below, as they cannot be set up to different alarm
formats.
Common options
These options are available for all pins for all alarm formats
6.13.1.1 Monitor cable
Monitors tamper detection when ticked. This requires resistors to be
fitted at the alarm panel end of the cable to enable the terminal to
detect cable faults and/or tampers.
Wire the alarm outputs from the panel to the position in the diagram
marked as a switch – open is the alarm condition and closed is the
restore condition.

6.13.1.2 Enable

Enables this pin input when ticked.

6.13.1.3 Inverse polarity

When ticked, this reverses the function of the inputs "Set" and "Restore". This will mean that the "Set" will
be a closed circuit and the "Restore" will be an open circuit.
