Activation of this input unlocks the door and starts the door unlock timer.
When the door is open this input is active and when the door is closed the input is
inactive.
The general purpose input is mainly used for establishing a correlation with a
specific output. When a general purpose input becomes active it is considered as
an event that correlates to either turn on or off a general purpose output, or to turn
on or off the high security mode. Other correlated events include different
functions such as forced entry, auto relock or interlock.
An active state is when the input circuit is considered active and is configured as
one of the following:
•
open
•
short (default)
There are some restrictions in configuring the active state depending on what
kind of supervision is required.
If the input is not supervised the input is either 'open' or 'closed'. If the input is
supervised for 'open' the active state cannot be 'open'.
If the input is supervised for both 'open' and 'short' the active state cannot be
'open'.
Each input is configured for a specific type of supervision depending on your
particular installation requirements as follows:
•
no supervision
•
supervise for open
•
supervise for short
•
supervise for both open and short
When inputs are configured with no supervision, the active state is either 'open'
or 'short' as programmed.
