The input to the EDIO module consists of
normally open switches, with a 10 K ohm, 1/4
watt EOL resistor in parallel across the return
channel, and a 3.3 K ohm, 1/4 watt resistor in
series with each switch.
NOTE
If using more than one switch, the rst
active condition (switch closed) must be
latched. Any subsequent closed switch
will indicate a short circuit fault condition.
Make no connection to “+ Supply” terminal.
Input — Deluge and Pre-Action
The initiating device circuit(s) for use with the
deluge and pre-action system configuration
must use Class A wiring or be wired within 20
feet and in conduit from the EDIO.
Two-Wire Smoke Detectors
The EDIO supports 2-wire devices from Kidde-
Fenwal and Apollo. Figure 3-29 shows the
wiring for Apollo detectors connected to EDIO
Channel 1 through terminals 1 and 2.
Figure 3-30 shows the typical wiring for Kidde-
Fenwal detectors connected to the EDIO
through Channel 1 using terminals 1 and 2.
The EDIO supports either brand of detection
products, however, mixing brands is not
supported on either a single channel or module.
IMPORTANT
No more than 15 devices can be
connected per channel.
Unsupervised Output
Connect external system wiring to the
appropriate terminals on the terminal block.
See Figure 3-31.
No connection should be made to “+ Supply”
terminal.
