The parameter describes input configuration and stable state of input. Any change
of that state causes alarm message to be sent. The following configuration types are
available: NO / NC / EOL-NO / EOL-NC / DEOL-NO / DEOL-NC. NC type input must
be closed for the whole time. Line interruption causes its induction. NO type input
remains open. It activates when closed. EOL and DEOL (single end-of-line resistor
and double end-of-line resistor) differ with 1 or 2 resistors allowing distinguishing
alarm from sabotage. Electric diagrams for all configuration types were described in
chapter 3.4. INPUT CONFIGURATION.
7.3.1.2.
Delay
This parameter means minimum time for change maintenance at input so that it
would be detected by transmitter. Factory setting is 400 ms.
7.3.1.3.
Locks
With this option you can lock any input of transmitter, and as a result condition
changes on this input will be ignored and will not be reported to monitoring station.
Lock may be persistent or temporary.
In case of temporary lock – user can set lock time and number of input state
changes after which lock occurs. Lock time is counted from first input state change.
More detailed information about input locks is shown on a diagram below.
Both types of lock can be deactivated by SMS command (see RLIMIT command
described in chapter 9).
