The Loop Detector Interface allows connection of up to three
plug-in detectors associated with standard functions. The
board is designed to fit in the FAAC standard 16” x 14” enclo-
sure on the existing DIN rail. To connect the interface board:
1) Connect the 2EASY BUS from the E024U to the interface
board (no polarity) - Green Wires
2) Connect pin 8 on the E024U board (+24V) to the +24
input on the interface board - Red Wire
3) Connect pin 7 on the E024U board (GND) to the GND input
on the interface board - Black Wire
4) Connect the loops to the interface board as in the figure
below

Turn the power on on the E024U board. The LED on the inter-
face board will blink briefly and then will stay ON solid if the
BUS connection is working correctly.
IMPORTANT
: Briefly press the SW1 button on the E024U board
to make it aware of the presence of the additional interface
board.
To make sure the board is working properly you can check
the behaviour of BUS LED on the E024U board. It will be nor-
mally on when none of the loop detectors is active. If any of
the detectors is activated the LED will turn off.
12.2 LOOP DETECTORS INTERFACE (p/n 2670)
NOTE
: You can use the shadow loop interface OR the loop detectors interface but not both at the same time. If two monitored
open safeties are required the additional loop detectors (other than the shadow) must be wired directly to the E024U board.
