Activation methods 9
Installation and Programming manual
STOP INPUT
The STOP signal allows you to force the Ivy unit to standby status
thus blocking all signaling. Once this signal is removed, the device
will restart the evaluation process and if the alarm conditions are
still active, it will trigger the respective signals.
Note
Although the STOP input is fully programmable, the manufacturer
strongly recommends an “applied” signal configuration rather than a
“removed” signal configuration, in order to avoid the risk of disablement
in the event of wire cutting.
LED INPUT
This input, which activates when it connects to negative, operates
as an ancillary channel which the panel can use to activate any type
of signal, in accordance with the configuration of the Ivy unit.
3-2Managing multi-alarm
conditions
There is no priority amongst the various signals. If the Ivy unit
detects signals, it will activate the programmed signaling cycle and,
in the event of concurrent activations, add on the respective signals.
Restoral of a detected signal annuls the respective alarm cycle
automatically, but it does not annul alarm cycles relating to other
signals. The Ivy unit will restore to standby status when all alarm
conditions cease.
