Normal
This is the default mode for a terminal.
Set / unset
In a normal alarm installation, the terminal is used with an attached alarm panel.
However, if the requirements for monitoring are simple, requiring only a few
alarm events like set & unset or entry / exit alarms (e.g., ATM monitoring), the
terminal can be set up to be a simple alarm panel using the pin inputs.
6.11.2.1 Set / unset pin
Configuration options for the Set/Unset pin.
6.11.2.1.1 Pin number
Allocate which pin is for the set and unset signals.
6.11.2.1.2 Trigger mode
This sets the trigger mode to "normal", which means that the unit is unset when
the input pin is "open circuit". This method is suitable for an external physical
switch such as a key-switch.
The trigger mode can be set to "pulse", which means that a pulse on the
set/unset input toggles the set/unset status. This is suitable for an external device such as a proximity tag
reader.
6.11.2.2 Exit delay
This option lets you set the exit delay timer. The default is 10 seconds.
6.11.2.3 Entry Pin
This option lets you allocate which pin is to be used for the entry signal.
6.11.2.4 Entry delay
This option lets you set up the entry delay timer. The default is 10 seconds.
6.11.2.5 Set status relay
This option lets you allocate which relay output is to be the set/unset status
indicator and to set the default state to "Normally open" or "Normally closed".
The default is "Normally open".
6.11.2.6 Alarm status relay
This option lets you enable relay D as the alarm status indicator. This means that
if any (enabled) pin Inputs are in an alarm state, the relay will change state
according to what the default state is set to (default is normally open).
