Z Command
Function:
Creates groups of inputs (Zones). Allows shunting of multiple inputs.
One command can shunt all required points on the panel rather than
one command for each point. Commands are similar to the G command.
Creation:
Z
=pn_zgn_input_input etc.
zgn: The number of the group being created (up to 16 of these groups
can be created)
input: The input number included in the group.
Control:
Through O commands with energize and de-energize such as:
_
O
=pn_
Z
_zgn_E<CR>
or
_
O
=pn_
Z
_zgn_D<D>

If two or more inputs are interlocked to a single output to energize on alarm and
de-energize on normal, both/all inputs must be normal before the interlock will
allow the relay to de-energize.
1. This E (Energize) action will allow situations where, for example, several input
points can be interlocked to one relay which is driving a sounder, visual alert or
digital dialer. When several inputs go into alarm and remain in alarm all at
once, the relay will not be turned off after one of them goes back to normal.
Rather all inputs must go back to normal before the output will be turned off.
2. The above operation is standard. An alternate method, where one input returning
to normal would de-energize the relay, is offered as an option through the
use of a terminal or text command. The command is written with a G designation
in place of the E for energize.
