NOTE
No connection should be made to the “+
Supply” terminal.
Supervised Input (IDC) Open Circuit
Supervision Class B
Connect external system wiring to the
appropriate terminals on the DCIO terminal
block. See Figure 3-39.
The input to the DCIO module consists of one
or more normally open switches, with a 10K
ohm, 1/4 watt EOL resistor in parallel across
the last switch.
NOTE
No connection should be made to the “+
Supply” terminal.
Supervised Input (IDCSC) Open
and Short Circuit Supervision
(Three state – open, switch closure, and
short) Class B
Connect external wiring to the appropriate
terminals on the DCIO terminal block. See
Figure 3-40. Indication of short circuit fault is
provided.
The input to the DCIO module consists of a
normally open switch, with a 10 K ohm, 1/4
watt EOL resistor in parallel across the switch,
and a 3.3 K ohm, 1/4 watt resistor in series with
the switch.
NOTE
No connection should be made to the “+
Supply” terminal. For correct operation,
only one input switch can be used per
channel.
Supervised Output Notication (Horns
and Strobes) Supervised Outputs for
Open & Short Circuits Class B
Connect external wiring to the appropriate
terminals on the DCIO terminal block. See
Figure 3-41.
NOTE
Polarity MUST be observed when
connecting the notication device.
It is critical to use a notification device
approved for fire alarm notification. These
devices are polarized and do not require the
use of an external diode for the supervision
of the circuit. Wire one or more notification
devices to the output, with a 10 K ohm, 1/4 watt
EOL resistor in parallel across the last device.
NOTE
No connection should be made to the “+
Supply” terminal.
