Two-Wire Smoke Detectors
The EDIO supports 2-wire devices from Kidde-Fenwal
and Apollo. Figure 3-31 shows the wiring for Apollo
detectors connected to EDIO Channel 1 through
terminals 1 and 2.
Figure 3-32 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 3-33.
No connection should be made to “+ Supply”
terminal.
