Examples of Input Connection Methods
Single without EOL and without TAMPER Supervision
(Limit of 1 Detection Device on the Input)
When using this method, only one device can be connected to the
input. The input must be connected using only one Contact (NO
or NC: programmable per INPUT in Software) as described in the
following gure. This setup will not support WIRE CUT or WIRE
SHORT supervision, but will generate an alarm condition when the
state of the input is breached.
WIRE SHORT supervision: NO
WIRE CUT supervision: NO
Doubled with WIRE CUT Supervision
(2 Detection Device on the Input)
When using this method, two device can be
connected to the input. The input must be
connected using two Contacts (NO or NC:
programmable per INPUT in Software) as
described in the following gure. This setup
will support WIRE CUT supervision but not
WIRE SHORT supervision and will generate
an alarm condition when the state of one of
the input is breached.
WIRE SHORT supervision: NO
WIRE CUT supervision: YES (Detected as INPUTS CUT)
Doubled with WIRE SHORT and WIRE CUT Supervision
(2 Detection Device on the Input)
When using this method, two device can be
connected to the input. The input must be
connected using two Contacts (NO or NC:
programmable per INPUT in Software) as
described in the following gure. This setup
will support WIRE CUT and WIRE SHORT
supervision and will generate an alarm
condition when the state of one of the input is
breached.
WIRE SHORT supervision: YES (Detected as INPUTS SHORT)
WIRE CUT supervision: YES (Detected as INPUTS CUT)
